1.spring security入门

decurity-demo.sql 数据库验证的文件

密码是123或者123456/ 可以使用 new BCryptPasswordEncoder_().encode(“123”)_;加密出来
模板项目地址https://gitee.com/find_me/java-findme

1.创建项目，引入依赖

  <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency>

引入依赖后，项目中所有的接口就会被保护起来，项目默认用户名为user，密码为启动后随即生成的，在控制台打印的密码

2.security的其他配置方式

spring:security:user: name: find mepassword: 123456roles: admin

2.2基于内存

当然，开发者也可以自定义类继承自WebSecurityConfigurerAdapter ，进而实现对 Spring Security
更多的自定义配置，例如基于内存的认证，配置方式如下：

@Configuration public class MyWebSecurityConfig extends WebSecurityConfigurerAdapter { // 密码不加密的配置 ，过时的方法@Bean //PasswordEncoder passwordEncoder () { //return NoOpPasswordEncoder. getlnstance () ; // }// 密码需要加密@BeanPasswordEncoder passwordEncoder() {return new BCryptPasswordEncoder();}//基于内存的配置@Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {auth.inMemoryAuthentication().withUser("javaboy").password("$2a$10$KlbLLUVVyvP0/vuhlabv0upg/ALdCrVEhUJOJDEND5ZtZJ.nGfVCm").roles("admin").and().withUser("findme").password("$2a$10$KlbLLUVVyvP0/vuhlabv0upg/ALdCrVEhUJOJDEND5ZtZJ.nGfVCm").roles("user");}

代码解释：
·自定义 MyWebSecurityConfig 继承自 WebSecurityConfigurerAdapter ，并重写configure(AuthenticationManagerBuilder auth）方法，在该方法中配直两个用户，一个用户名是
admin，密码123 ，具备两个角色 ADMIN USER 另一个用户名是 findme，密码是 123 ，具备一个角色USER
Spring Security 本是 0.6 Spring Security 中引入了多种密码加密方式，开发者必须指定其中一种， NoOpPasswordEncoder ，即不对密码进行加密。

注意：基于配置和内存的方式在配置角色的时候不需要添加"ROLE_".基于数据库的需要

2.3HttpSecurity（入门配置此文件）

根据实际情况进行角色配置

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {@Resourceprivate ObjectMapper objectMapper;@BeanPasswordEncoder passwordEncoder() {return new BCryptPasswordEncoder();}// 配置登录的账号@Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {auth.inMemoryAuthentication().withUser("javaboy").password("$2a$10$KlbLLUVVyvP0/vuhlabv0upg/ALdCrVEhUJOJDEND5ZtZJ.nGfVCm").roles("admin").and().withUser("findme").password("$2a$10$KlbLLUVVyvP0/vuhlabv0upg/ALdCrVEhUJOJDEND5ZtZJ.nGfVCm").roles("user");}//基本的httpSecurity配置// 1.请求路径角色// 2.配置表单登录// 3.配置登录成功，失败或者登出的处理方式// authentication里面存放登录成功后的信息//      {//            "password": null, 密码//             "username": "javaboy",//             "authorities": [ 具备的角色//            {//                "authority": "ROLE_admin" //            }//        ],//            "accountNonExpired": true, 账户没有过期，//                "accountNonLocked": true, 账户没有锁定//                "credentialsNonExpired": true, 密码没有过期//                "enabled": true 账户可用//        },@Overrideprotected void configure(HttpSecurity http) throws Exception {http.authorizeRequests()//开启配置.antMatchers("/admin/**").hasRole("admin")//路径符合这个需要admin角色
//                .antMatchers("user/**").hasAnyRole("admin", "user")//路径符合这个，需要这两个的任意一个.antMatchers("/user/**").access("hasAnyRole('user','admin')").anyRequest().authenticated()//其他请求，登录后就可以访问.and().formLogin()//表单登录.loginProcessingUrl("/doLogin")//处理登录请求的地址.loginPage("/login")//配置登录页面（实际上还是一个请求地址） 前后端分类不存在这种页面 这里还是访问的应该请求，会根据这请求去返回登录页面.usernameParameter("uname")//修改登录的key.passwordParameter("passwd")//修改登录的key.successHandler(new AuthenticationSuccessHandler() { //登录成功的处理@Override// authentication保存了登录成功后的信息public void onAuthenticationSuccess(HttpServletRequest req, HttpServletResponse resp,Authentication authentication) throws IOException, ServletException {resp.setContentType("application/json;charset=utf-8");PrintWriter out = resp.getWriter();Map<String, Object> map = new HashMap<>();map.put("status", 200);map.put("msg", authentication.getPrincipal());out.write(new ObjectMapper().writeValueAsString(map));out.flush();out.close();}}).failureHandler(new AuthenticationFailureHandler() {//登录失败的处理@Override // e登录失败的异常public void onAuthenticationFailure(HttpServletRequest req, HttpServletResponse resp,AuthenticationException e) throws IOException, ServletException {resp.setContentType("application/json;charset=utf-8");PrintWriter out = resp.getWriter();Map<String, Object> map = new HashMap<>();map.put("status", 401);if (e instanceof LockedException) {map.put("msg", "账户被锁定，登录失败!");} else if (e instanceof BadCredentialsException) {map.put("msg", "用户名或密码输入错误，登录失败!");} else if (e instanceof DisabledException) {map.put("msg", "账户被禁用，登录失败!");} else if (e instanceof AccountExpiredException) {map.put("msg", "账户过期，登录失败!");} else if (e instanceof CredentialsExpiredException) {map.put("msg", "密码过期，登录失败!");} else {map.put("msg", "登录失败!");}out.write(new ObjectMapper().writeValueAsString(map));out.flush();out.close();}}).permitAll().and().logout().logoutUrl("/logout") //配置注销请求的地址.logoutSuccessHandler(new LogoutSuccessHandler() {//注销成功后的回调@Overridepublic void onLogoutSuccess(HttpServletRequest req, HttpServletResponse resp,Authentication authentication) throws IOException, ServletException {resp.setContentType("application/json;charset=utf-8");PrintWriter out = resp.getWriter();Map<String, Object> map = new HashMap<>();map.put("status", 200);map.put("msg", "注销登录成功!");out.write(new ObjectMapper().writeValueAsString(map));out.flush();out.close();}}).and().csrf().disable();/*** 权限不足处理*/http.exceptionHandling().accessDeniedHandler(new AccessDeniedHandler() {@Overridepublic void handle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, AccessDeniedException e) throws IOException {httpServletResponse.setContentType(MediaType.APPLICATION_JSON_UTF8_VALUE);Map<String, Object> failureMap = new HashMap<>();failureMap.put("code", 403);failureMap.put("msg", "权限不足！");httpServletResponse.getWriter().println(objectMapper.writeValueAsString(failureMap));}});
//        /**
//         * 未登陆处理
//         */
//        http.exceptionHandling().authenticationEntryPoint(new AuthenticationEntryPoint() {//            @Override
//            public void commence(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, AuthenticationException e) throws IOException {//
//
//                httpServletResponse.setContentType(MediaType.APPLICATION_JSON_UTF8_VALUE);
//
//                Map<String, Object> failureMap = new HashMap<>();
//                failureMap.put("code", 401);
//                failureMap.put("msg", "请先登录！");
//
//                httpServletResponse.getWriter().println(objectMapper.writeValueAsString(failureMap));
//
//            }
//        });}
}

2.4多个HttpSecurity的配置（复杂业务场景下）—security

参考项目 spring-security-me/security
采用静态内部类的方式采用order设置优先级，数字越小，优先级越大

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true,securedEnabled = true) //开启方法安全
public class MultiHttpSecurityConfig {@BeanPasswordEncoder passwordEncoder() {return new BCryptPasswordEncoder();}@Autowiredprotected void configure(AuthenticationManagerBuilder auth) throws Exception {auth.inMemoryAuthentication().withUser("javaboy").password("$2a$10$G3kVAJHvmRrr6sOj.j4xpO2Dsxl5EG8rHycPHFWyi9UMIhtdSH15u").roles("admin").and().withUser("").password("$2a$10$kWjG2GxWhm/2tN2ZBpi7bexXjUneIKFxIAaMYJzY7WcziZLCD4PZS").roles("user");}@Configuration@Order(1)public static class AdminSecurityConfig extends WebSecurityConfigurerAdapter{@Overrideprotected void configure(HttpSecurity http) throws Exception {http.antMatcher("/admin/**").authorizeRequests().anyRequest().hasAnyRole("admin");//只有这种格式的路径才会去要求角色}}@Configurationpublic static class OtherSecurityConfig extends WebSecurityConfigurerAdapter{@Overrideprotected void configure(HttpSecurity http) throws Exception {http.authorizeRequests().anyRequest().authenticated().and().formLogin().loginProcessingUrl("/doLogin").permitAll().and().csrf().disable();}}
}

2.5配置方法安全

在Security上面加上

@EnableGlobalMethodSecurity(prePostEnabled = true,securedEnabled = true) //开启方法安全
然后在方法上加PreAuthorize注解

@Service
public class MethodService {@PreAuthorize("hasRole('admin')")// 这个方法需要admin角色public String admin() {return "hello admin";}@Secured("ROLE_user")  //需要user角色public String user() {return "hello user";}@PreAuthorize("hasAnyRole('admin','user')")//需要两者之一public String hello() {return "hello hello";}
}

2.6基于数据库的认证（基础入门）-----sercuty-db/sercurity-dy

权限模型

权限实际开发模型

1.定义实体类user（继承UserDetails）和role

security-demo.sql


public class User implements UserDetails {private Integer id;private String username;private String password;private Boolean enabled;private Boolean locked;private List<Role> roles;public List<Role> getRoles() {return roles;}public void setRoles(List<Role> roles) {this.roles = roles;}public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}// 返回用户所有的角色@Overridepublic Collection<? extends GrantedAuthority> getAuthorities() {List<SimpleGrantedAuthority> authorities = new ArrayList<>();// 重新整理一下 角色认证要以ROLE_开始 数据库没有就要在这里手动拼接for (Role role : roles) {authorities.add(new SimpleGrantedAuthority(role.getName()));}return authorities;}@Overridepublic String getPassword() {return password;}public void setPassword(String password) {this.password = password;}@Overridepublic String getUsername() {return username;}// 账户是否未过期 目前数据库没有就直说true@Overridepublic boolean isAccountNonExpired() {return true;}// 账户是否未锁定@Overridepublic boolean isAccountNonLocked() {return !locked;}// 密码是否未过期@Overridepublic boolean isCredentialsNonExpired() {return true;}// 是否可用@Overridepublic boolean isEnabled() {return enabled;}public void setUsername(String username) {this.username = username;}public void setEnabled(Boolean enabled) {this.enabled = enabled;}public void setLocked(Boolean locked) {this.locked = locked;}
}

2.配置SecurityConfig

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {@AutowiredUserService userService;@BeanPasswordEncoder passwordEncoder() {return new BCryptPasswordEncoder();}// 此处去调用数据库的或者采用静态数据@Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {auth.userDetailsService(userService);}@Overrideprotected void configure(HttpSecurity http) throws Exception {//对于不同的路径要不同的角色 静态配置http.authorizeRequests().antMatchers("/dba/**").hasRole("dba").antMatchers("/admin/**").hasRole("admin").antMatchers("/user/**").hasRole("user").anyRequest().authenticated().and().formLogin().permitAll().and().csrf().disable();}// 角色继承的bean@BeanRoleHierarchy roleHierarchy() {RoleHierarchyImpl roleHierarchy = new RoleHierarchyImpl();// 以前String hierarchy = "dba > admin admin > user";// 现在String hierarchy = "dba > admin \n admin > user";roleHierarchy.setHierarchy(hierarchy);return roleHierarchy;}

3.动态权限配置的Security写法

1. 1.先定义MyFilter实现FilterInvocationSecurityMetadataSource

主要就是分析出需要哪些角色

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {@AutowiredUserService userService;@AutowiredMyFilter myFilter;@AutowiredMyAccessDecisionManager myAccessDecisionManager;@BeanPasswordEncoder passwordEncoder() {return new BCryptPasswordEncoder();}@Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {auth.userDetailsService(userService);}//    @Bean
//    RoleHierarchy roleHierarchy() {//        RoleHierarchyImpl roleHierarchy = new RoleHierarchyImpl();
//        String hierarchy = "dba > admin \n admin > user";
//        roleHierarchy.setHierarchy(hierarchy);
//        return roleHierarchy;
//    }
@Bean
@Override
protected UserDetailsService userDetailsService() {return super.userDetailsService();
}@Overrideprotected void configure(HttpSecurity http) throws Exception {http.authorizeRequests().withObjectPostProcessor(new ObjectPostProcessor<FilterSecurityInterceptor>() {@Overridepublic <O extends FilterSecurityInterceptor> O postProcess(O o) {o.setAccessDecisionManager(myAccessDecisionManager);o.setSecurityMetadataSource(myFilter);return o;}}).and().formLogin().permitAll().and().csrf().disable();}
}

2.编写MyAccessDecisionManager继承 AccessDecisionManager


@Component
public class MyAccessDecisionManager implements AccessDecisionManager {/**** @param authentication 当前用户具备的角色* @param o* @param collection  当前路径需要的角色，这里是在MyFiter处理后得到的* @throws AccessDeniedException* @throws InsufficientAuthenticationException*/@Overridepublic void decide(Authentication authentication, Object o, Collection<ConfigAttribute> collection) throws AccessDeniedException, InsufficientAuthenticationException {for (ConfigAttribute attribute : collection) {if ("ROLE_login".equals(attribute.getAttribute())) {// 如果是返回的ROLE_login说明你请求的路径不存在，所有判断你有没有登录 登录的就直接放行if (authentication instanceof AnonymousAuthenticationToken) {throw new AccessDeniedException("非法请求!");} else {return;}}// 获取我具备的角色Collection<? extends GrantedAuthority> authorities = authentication.getAuthorities();// 做匹配for (GrantedAuthority authority : authorities) {if (authority.getAuthority().equals(attribute.getAttribute())) {return;}}}// 例如，我具备某些角色，但是此角色没有此路径的权限，那就是非要请求throw new AccessDeniedException("非法请求!");}@Overridepublic boolean supports(ConfigAttribute configAttribute) {return true;}@Overridepublic boolean supports(Class<?> aClass) {return true;}
}

3.1SecurityConfig的写法


@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {@AutowiredUserService userService;@AutowiredMyFilter myFilter;@AutowiredMyAccessDecisionManager myAccessDecisionManager;@BeanPasswordEncoder passwordEncoder() {return new BCryptPasswordEncoder();}@Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {auth.userDetailsService(userService);}/@Overrideprotected void configure(HttpSecurity http) throws Exception {http.authorizeRequests().withObjectPostProcessor(new ObjectPostProcessor<FilterSecurityInterceptor>() {//FilterSecurityInterceptor 拦截器@Overridepublic <O extends FilterSecurityInterceptor> O postProcess(O o) {o.setAccessDecisionManager(myAccessDecisionManager);o.setSecurityMetadataSource(myFilter);return o;}}).and().formLogin().permitAll().and().csrf().disable();}
}

2.7spring security整合oauth2—oauth2

2.7.1配置资源服务器 ResourceServerConfig

/*** 资源服务器*/
@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {@Overridepublic void configure(ResourceServerSecurityConfigurer resources) throws Exception {//指定资源id stateless配置基于令牌认证resources.resourceId("rid").stateless(true);}//此处角色路径可以从数据库加载//    @Override
//    public void configure(HttpSecurity http) throws Exception {//        // 路径的角色
//        http.authorizeRequests().antMatchers("/admin/**").hasRole("admin")
//                .antMatchers("/user/**").hasRole("user")
//                .anyRequest().authenticated();
//    }// 从数据库加载如下@AutowiredMyFilter myFilter;@AutowiredMyAccessDecisionManager myAccessDecisionManager;/*** @param http* @throws Exception*/@Overridepublic void configure(HttpSecurity http) throws Exception {http.authorizeRequests().withObjectPostProcessor(new ObjectPostProcessor<FilterSecurityInterceptor>() {@Overridepublic <O extends FilterSecurityInterceptor> O postProcess(O o) {o.setAccessDecisionManager(myAccessDecisionManager);o.setSecurityMetadataSource(myFilter);return o;}}).and().formLogin().permitAll().and().csrf().disable();}}

2.7.2授权服务器 AuthorizationServerConfig


/*** 授权服务器*/
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {// 支持password的认证模式@AutowiredAuthenticationManager authenticationManager;// 配置redis就会有@AutowiredRedisConnectionFactory redisConnectionFactory;// 密码加密方式@AutowiredUserDetailsService userDetailsService;@BeanPasswordEncoder passwordEncoder() {return new BCryptPasswordEncoder();}@Overridepublic void configure(ClientDetailsServiceConfigurer clients) throws Exception {//配置在内存中//配置认证模式//配置授权模式//资源id(名字)//配置的密码123456clients.inMemory().withClient("password").authorizedGrantTypes("password", "refresh_token").accessTokenValiditySeconds(1800).resourceIds("rid").scopes("all").secret("$2a$10$LcM2.fVWzB50vitKLrPPDugS/owlp.qVVT5jA0EyJuFeez6S5hTkm");}// 配置令牌的存储@Overridepublic void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {endpoints.tokenStore(new RedisTokenStore(redisConnectionFactory)) //.authenticationManager(authenticationManager).userDetailsService(userDetailsService);}@Overridepublic void configure(AuthorizationServerSecurityConfigurer security) throws Exception {security.allowFormAuthenticationForClients();}}

2.7.3security配置文件

@Override@Beanprotected AuthenticationManager authenticationManager() throws Exception {return super.authenticationManager();}@Bean@Overrideprotected UserDetailsService userDetailsService() {return super.userDetailsService();}//  静态的加载用户
//    @Override
//    protected void configure(AuthenticationManagerBuilder auth) throws Exception {//        auth.inMemoryAuthentication()
//                .withUser("javaboy").password("$2a$10$LcM2.fVWzB50vitKLrPPDugS/owlp.qVVT5jA0EyJuFeez6S5hTkm").roles("admin")
//                .and()
//                .withUser("finde")
//                .password("$2a$10$kwLIAqAupvY87OM.O25.Yu1QKEXV1imAv7jWbDaQRFUFWSnSiDEwG")
//                .roles("user");
//    }
// 从数据库加载用户@AutowiredUserService userService;@Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {auth.userDetailsService(userService);}//放开oauth相关的请求，不就行拦截@Overrideprotected void configure(HttpSecurity http) throws Exception {http.antMatcher("/oauth/**").authorizeRequests().antMatchers("/oauth/**").permitAll().and().csrf().disable();}

2.7.4 MyFilter

@Component
public class MyFilter implements FilterInvocationSecurityMetadataSource {// 做路径匹配的 提供了路径批评规则AntPathMatcher pathMatcher = new AntPathMatcher();@AutowiredMenuService menuService;/*** 分析请求地址 根据请求的地址，分析出需要哪些角色* @param o* @return* @throws IllegalArgumentException*/@Overridepublic Collection<ConfigAttribute> getAttributes(Object o) throws IllegalArgumentException {// 请求的地址String requestUrl = ((FilterInvocation) o).getRequestUrl();// 所有的菜单 ，这里可以给一个缓存List<Menu> allMenus = menuService.getAllMenus();for (Menu menu : allMenus) {// 如果请求地址批评上了if (pathMatcher.match(menu.getPattern(), requestUrl)) {List<Role> roles = menu.getRoles();String[] rolesStr = new String[roles.size()];//查看需要哪些角色 rolesStr，防止角色集合for (int i = 0; i < roles.size(); i++) {rolesStr[i] = roles.get(i).getName();}return SecurityConfig.createList(rolesStr);}}// 没有匹配上路径，这个就是标识符号，看在数据库中没有这个路径，怎么处理return SecurityConfig.createList("ROLE_login");}@Overridepublic Collection<ConfigAttribute> getAllConfigAttributes() {return null;}@Overridepublic boolean supports(Class<?> aClass) {return true;}
}

2.7.5 MyAccessDecisionManager


@Component
public class MyAccessDecisionManager implements AccessDecisionManager {/**** @param authentication 当前用户具备的角色* @param o* @param collection  当前路径需要的角色，这里是在MyFiter处理后得到的* @throws AccessDeniedException* @throws InsufficientAuthenticationException*/@Overridepublic void decide(Authentication authentication, Object o, Collection<ConfigAttribute> collection) throws AccessDeniedException, InsufficientAuthenticationException {for (ConfigAttribute attribute : collection) {if ("ROLE_login".equals(attribute.getAttribute())) {// 如果是返回的ROLE_login说明你请求的路径不存在，所有判断你有没有登录 登录的就直接放行if (authentication instanceof AnonymousAuthenticationToken) {throw new AccessDeniedException("非法请求!");} else {return;}}// 获取我具备的角色Collection<? extends GrantedAuthority> authorities = authentication.getAuthorities();// 做匹配for (GrantedAuthority authority : authorities) {if (authority.getAuthority().equals(attribute.getAttribute())) {return;}}}// 例如，我具备某些角色，但是此角色没有此路径的权限，那就是非要请求throw new AccessDeniedException("非法请求!");}@Overridepublic boolean supports(ConfigAttribute configAttribute) {return true;}@Overridepublic boolean supports(Class<?> aClass) {return true;}
}

2.7.6 postman测试 -请求token

post http://127.0.0.1:8981/oauth/token
Body x-www-form-urlencoded
[{“key”:“username”,“value”:“admin”},
{“key”:“password”,“value”:“123”},
{“key”:“grant_type”,“value”:“password”},
{“key”:“client_id”,“value”:“password”},
{“key”:“scope”,“value”:“all”},
{“key”:“client_secret”,“value”:“123456”}]

{"username":"admin", "password":"123","grant_type":"password","client_id":"password","scope":"all","client_secret":"123456",
}

结果
{
“access_token”: “d1bdfd01-e06a-4b4e-a661-a49012da9afa”,
“token_type”: “bearer”,
“refresh_token”: “d31082b6-68a7-46b5-937a-62a24b186970”,
“expires_in”: 1325,
“scope”: “all”
}

换回新的token

{"grant_type":"refresh_token", "refresh_token":"d31082b6-68a7-46b5-937a-62a24b186970","grant_type":"password","client_secret":"123456",
}

2.8spring security支持json登录—security-dy/security-db/oauth2

2.8.1重写UsernamePasswordAuthenticationFilter方法

public class MyAuthenticationFilter extends UsernamePasswordAuthenticationFilter {@Overridepublic Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throwsAuthenticationException {if (!request.getMethod().equals("POST")) {throw new AuthenticationServiceException("Authentication method not supported: " + request.getMethod());}if (request.getContentType().equals(MediaType.APPLICATION_JSON_VALUE)) {//说明用户以 JSON 的形式传递的参数String username = null;String password = null;try {Map<String, String> map = new ObjectMapper().readValue(request.getInputStream(), Map.class);username = map.get("username");password = map.get("password");} catch (IOException e) {e.printStackTrace();}if (username == null) {username = "";}if (password == null) {password = "";}username = username.trim();UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(username, password);// Allow subclasses to set the "details" propertysetDetails(request, authRequest);return this.getAuthenticationManager().authenticate(authRequest);}return super.attemptAuthentication(request, response);}

2.8.2注入重写的方法

在securityconfig中写入一下文件

 // 配置支持json登录@BeanMyAuthenticationFilter myAuthenticationFilter() throws Exception {MyAuthenticationFilter filter = new MyAuthenticationFilter();filter.setAuthenticationManager(authenticationManagerBean());return filter;}/**** @param http* @throws Exception*/@Overrideprotected void configure(HttpSecurity http) throws Exception {http.addFilterAt(myAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class);}

2.8.3配置登录成功后的转跳和失败后转跳

在myAuthenticationFilter中配置
此时成功和失败的回调只能在fiter中配置，cnfigure中的配置是失效的

  // 配置支持json登录@BeanMyAuthenticationFilter myAuthenticationFilter() throws Exception {MyAuthenticationFilter filter = new MyAuthenticationFilter();filter.setAuthenticationManager(authenticationManagerBean());filter.setAuthenticationSuccessHandler(new AuthenticationSuccessHandler() { //登录成功的处理@Override// authentication保存了登录成功后的信息public void onAuthenticationSuccess(HttpServletRequest req, HttpServletResponse resp,Authentication authentication) throws IOException, ServletException {resp.setContentType("application/json;charset=utf-8");PrintWriter out = resp.getWriter();Map<String, Object> map = new HashMap<>();map.put("status", 200);map.put("msg", authentication.getPrincipal());out.write(new ObjectMapper().writeValueAsString(map));out.flush();out.close();}});filter.setAuthenticationFailureHandler(new AuthenticationFailureHandler() {//登录失败的处理@Override // e登录失败的异常public void onAuthenticationFailure(HttpServletRequest req, HttpServletResponse resp,AuthenticationException e) throws IOException, ServletException {resp.setContentType("application/json;charset=utf-8");PrintWriter out = resp.getWriter();Map<String, Object> map = new HashMap<>();map.put("status", 401);if (e instanceof LockedException) {map.put("msg", "账户被锁定，登录失败!");} else if (e instanceof BadCredentialsException) {map.put("msg", "用户名或密码输入错误，登录失败!");} else if (e instanceof DisabledException) {map.put("msg", "账户被禁用，登录失败!");} else if (e instanceof AccountExpiredException) {map.put("msg", "账户过期，登录失败!");} else if (e instanceof CredentialsExpiredException) {map.put("msg", "密码过期，登录失败!");} else {map.put("msg", "登录失败!");}out.write(new ObjectMapper().writeValueAsString(map));out.flush();out.close();}});return filter;}

swagger的两种配置的效果如下

输入 Bearer ${token}

postman测试参数如下先获取token，在传递token
