kisso 是一个中间件，提供 cookie 搭建 java web sso 的组件式解决方案。

shiro是目前比较常用的轻量权限控制框架。

SpringBoot集成Shiro的文章比较多，我不多赘述。下面介绍SpringBoot集成kisso。

思路

• Spring集成Shiro
• Shiro托管项目session，使用Redis保存Shiro缓存信息
• SpringBoot集成kisso
• kisso单点登录同步shiro授权信息

步骤

1.SpringBoot集成Shiro

略。

2.Shiro托管项目session，使用Redis保存Shiro缓存信息

这个的详细操作过程在这个博文里介绍过了 https://my.oschina.net/qwzhang01/blog/1620339

3.SpringBoot集成kisso

1）添加配置文件sso.properties

sso.encoding=UTF-8
sso.secretkey=Kisso4SpringBootK80mAS
sso.cookie.name=uid
sso.cookie.domain=canyou.xyz
sso.cookie.maxage=7200
sso.login.url=http://canyou.xyz:8088/login

2）注入kisso组件

@Configuration
public class WebAppConfig extends WebMvcConfigurerAdapter {/*** 注入kisso拦截器** @param registry*/@Overridepublic void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(new SSOSpringInterceptor()).addPathPatterns("/**").excludePathPatterns("/login/**");super.addInterceptors(registry);}/*** 注入Kisso** @return*/@Bean(initMethod = "initKisso")public WebKissoConfigurer webKissoConfigurer() {WebKissoConfigurer webKissoConfigurer = new WebKissoConfigurer("sso.properties");return webKissoConfigurer;}
}

3）修改登录方法，登录成功，调用kisso，将登陆信息保存在cookie中

 @RequestMapping(value = "/login/check", method = RequestMethod.POST)public String login(@RequestParam(value = "ReturnURL", defaultValue = "") String retuenUrl, LoginUserVo user, RedirectAttributes redirectAttributes, HttpServletRequest request, HttpServletResponse response) {if (StrUtil.hasBlank(user.getUsername(), user.getPassword(), user.getSafecode_iput())) {redirectAttributes.addFlashAttribute("msg", "用户名或密码验证码都均能为空");return "redirect:/login";}if (!CaptchaKit.validate(user.getSafecode_iput(), request)) {redirectAttributes.addFlashAttribute("msg", "验证码错误");return "redirect:/login";}User checkUser = userService.getByUserName(user.getUsername());if (checkUser == null) {redirectAttributes.addFlashAttribute("msg", "用户不存在，请核对后重新登录");return "redirect:/login";}String encrypt = ShiroCrypt.encrypt(user.getPassword());if (!checkUser.getPassword().equals(encrypt)) {redirectAttributes.addFlashAttribute("msg", "密码错误，请核对后重新登录");return "redirect:/login";}if (userService.login(checkUser.getUsername(), checkUser.getPassword())) {HttpSession session = request.getSession();session.setAttribute("username", checkUser.getUsername());session.setAttribute("fullName", checkUser.getRealname());// 单点登录核心代码SSOToken ssoToken = new SSOToken();ssoToken.setUid(user.getUsername());ssoToken.setApp("oms");ssoToken.setIp(IpHelper.getIpAddr(request));// 将sessionid保存在kisso的cookie里面ssoToken.setData(request.getSession().getId());SSOHelper.setSSOCookie(request, response, ssoToken, false);return "redirect:/";}redirectAttributes.addFlashAttribute("msg", "登陆失败");return "redirect:/login";}

至此，kisso集成完成。符合配置在sso.properties中的domain的域名cookie中，都会同步登陆信息。

但是目前只是把登陆信息同步在kisso里面了，对于shiro来说，不同应用之间的认证、授权信息并没有同步，因此需要在所有系统里面根据kisso，添加shiro的认证授权信息。

4.kisso单点登录同步shiro授权信息

上面已经实现了应用session由shiro托管，shiro缓存实现共享。给shiro添加filter，通过filter，对于符合kisso的单点登录条件的应用，通过kisso获取原来已经登录项目的sessionid，将其写入新应用的cookie里面，即实现将原已经授权认证的项目的shiro信息同步至新项目中。

import cn.hutool.core.util.StrUtil;
import com.baomidou.kisso.SSOHelper;
import com.baomidou.kisso.SSOToken;
import org.apache.shiro.web.filter.AccessControlFilter;
import org.springframework.stereotype.Component;import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;@Component
public class KissoFilter extends AccessControlFilter {@Overrideprotected boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) throws Exception {HttpServletRequest httpServletRequest = (HttpServletRequest) request;String username = (String) httpServletRequest.getSession().getAttribute("username");return StrUtil.isNotBlank(username);}@Overrideprotected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws Exception {SSOToken ssoToken = SSOHelper.getToken((HttpServletRequest) request);if (ssoToken != null && ssoToken.getApp().equals("oms")) {Cookie cookie = new Cookie("csid", ssoToken.getData());cookie.setPath("/");((HttpServletResponse) response).addCookie(cookie);}return true;}
}

把filter注册为shiro的过滤器，过滤所有请求

@Beanpublic ShiroFilterFactoryBean shirFilter(SecurityManager securityManager) {ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();shiroFilterFactoryBean.setSecurityManager(securityManager);Map<String, Filter> filterMap = new HashMap<>();filterMap.put("authc_kisso", new KissoFilter());filterMap.put("shiro_kisso", new KiSsoShiroAuthFilter());filterMap.put("logout_kisso", new KiSsoShiroLogoutFilter());shiroFilterFactoryBean.setFilters(filterMap);Map<String, String> filterChainDefinitionMap = new LinkedHashMap<String, String>();        filterChainDefinitionMap.put("/js/**", "anon");filterChainDefinitionMap.put("/css/**", "anon");filterChainDefinitionMap.put("/fonts/**", "anon");filterChainDefinitionMap.put("/login/logout", "logout_kisso");filterChainDefinitionMap.put("/login/**", "anon");       filterChainDefinitionMap.put("/**", "authc_kisso, shiro_kisso");       shiroFilterFactoryBean.setLoginUrl("/login");shiroFilterFactoryBean.setSuccessUrl("/index");       shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);return shiroFilterFactoryBean;}
