Shiro(安全)

1、Shiro简介

Apache Shiro是一个强大且易用的Java安全框架,执行身份验证、授权、密码和会话管理。使用Shiro的易于理解的API,您可以快速、轻松地获得任何应用程序,从最小的移动应用程序到最大的网络和企业应用程序。

Shiro可以非常容易的开发出足够好的应用，不仅可以用在JavaSE环境，也可以用在JavaEE环境。

2、Shiro有哪些功能?

Authentication: 身份认证、登录,验证用户是不是拥有相应的身份;
Authorization:授权，即权限验证，验证某个已认证的用户是否拥有某个权限，即判断用户能否进行什么操
作,如:验证某个用户是否拥有某个角色，或者细粒度的验证某个用户对某个资源是否具有某个权限!
Session Manager:会话管理，即用户登录后就是第一次会话，在没有退出之前，它的所有信息都在会话中;
会话可以是普通的avaSE环境，也可以是Web环境;
Cnyptography: 加密，保护数据的安全性，如密码加密存储到数据库中，而不是明文存储;
Web Support: Web支持，可以非常容易的集成到Web环境;
Caching: 缓存，比如用户登录后，其用户信息,拥有的角色、权限不必每次去查,这样可以提高效率
Concurrency: Shiro支持多线程应用的并发验证，即，如在一个线程中开启另一个线程，能把权限自动的传
播过去
Testing:提供测试支持;
Run As: 允许一个用户假装为另- -个用户(如果他们允许)的身份进行访问;
Remember Me:记住我，这个是非常常见的功能，即一次登录后，下次再来的话不用登录了

3、Shiro架构(外部)

subject: 应用代码直接交互的对象是Subject, 也就是说Shiro的对外API核心就是Subject, Subject代表了当
前的用户，这个用户不-定是一个具体的人，与当前应用交互的任何东西都是Subject,如网络爬虫，机器人
等，与Subject的所有交互都会委托给SecurityManager; Subject其实是一个门面， SecurityManageer 才是
实际的执行者
SecurityManager: 安全管理器，即所有与安全有关的操作都会与SercurityManager交互，并且它管理着所有
的Subject,可以看出它是Shiro的核心，它负责与Shiro的其他组件进行交互，它相当于SpringMVC的
DispatcherServlet的角色
Realm: Shiro从Realm获取安全数据 (如用户,色，权限)，就是说SecurityManager 要验证用户身份,
那么它需要从Realm获取相应的用户进行比较，来确定用户的身份是否合法;也需要从Realm得到用户相应的
角色、权限，进行验证用户的操作是否能够进行，可以把Realm看成DataSource;

4、Shiro架构(内部)

Subject: 任何可以与应用交互的"用户;3
Security Manager:相当于SpringMVC中的DispatcherServlet;是Shiro的心脏，所有具体的交互都通过
Security Manager进行控制，它管理者所有的Subject,且负责进行认证，授权，会话，及缓存的管理。
Authenticator: 负责Subject认证，是一一个扩展点，可以自定义实现;可以使用认证策略(AuthenticationStrategy)，即什么情况下算用户认证通过了;
Authorizer:授权器，即访问控制器，用来决定主体是否有权限进行相应的操作;即控制着用户能访问应用中
的那些功能;
Realm: 可以有一个或者多个的realm,可以认为是安全实体数据源，即用于获取安全实体的，可以用DBC实
现，也可以是内存实现等等,由用户提供;所以- -般在应用中都需要实现自己的realm
SessionManager: 管理Session生命周期的组件,而Shiro并不仅仅可以用在Web环境，也可以用在普通的
JavaSE环境中
CacheManager: 缓存控制器,来管理如用户，角色，权限等缓存的;因为这些数据基本上很少改变,放到缓
存中后可以提高访问的性能;
Cryptography:密码模块, Shiro 提高了一些常见的加密组件用于密码加密，解密等

5、进入实践

打开官网文档: http://shiro.apache.org//tutorial.html

创建一个普通的maven父工程
创建一个普通的Maven子工程: shiro-01-helloworld
根据官方文档，我们来导入Shiro的依赖

1、导入依赖

<dependencies><!-- https://mvnrepository.com/artifact/org.apache.shiro/shiro-core --><dependency><groupId>org.apache.shiro</groupId><artifactId>shiro-core</artifactId><version>1.8.0</version></dependency><!-- configure logging --><dependency><groupId>org.slf4j</groupId><artifactId>jcl-over-slf4j</artifactId><version>1.7.21</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>1.7.21</version></dependency><!-- https://mvnrepository.com/artifact/org.apache.logging.log4j/log4j-core --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-core</artifactId><version>2.14.1</version></dependency></dependencies>

2、配置文件

resources目录下

log4j.properties

log4j.rootLogger=INFO, stdoutlog4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m %n# General Apache libraries
log4j.logger.org.apache=WARN# Spring
log4j.logger.org.springframework=WARN# Default Shiro logging
log4j.logger.org.apache.shiro=INFO# Disable verbose logging
log4j.logger.org.apache.shiro.util.ThreadContext=WARN
log4j.logger.org.apache.shiro.cache.ehcache.EhCache=WARN

shiro.ini，需要安装ini插件

[users]
# user 'root' with password 'secret' and the 'admin' role
root = secret, admin
# user 'guest' with the password 'guest' and the 'guest' role
guest = guest, guest
# user 'presidentskroob' with password '12345' ("That's the same combination on
# my luggage!!!" ;)), and role 'president'
presidentskroob = 12345, president
# user 'darkhelmet' with password 'ludicrousspeed' and roles 'darklord' and 'schwartz'
darkhelmet = ludicrousspeed, darklord, schwartz
# user 'lonestarr' with password 'vespa' and roles 'goodguy' and 'schwartz'
lonestarr = vespa, goodguy, schwartz# -----------------------------------------------------------------------------
# Roles with assigned permissions
#
# Each line conforms to the format defined in the
# org.apache.shiro.realm.text.TextConfigurationRealm#setRoleDefinitions JavaDoc
# -----------------------------------------------------------------------------
[roles]
# 'admin' role has all permissions, indicated by the wildcard '*'
admin = *
# The 'schwartz' role can do anything (*) with any lightsaber:
schwartz = lightsaber:*
# The 'goodguy' role is allowed to 'drive' (action) the winnebago (type) with
# license plate 'eagle5' (instance specific id)
goodguy = winnebago:drive:eagle5

3、测试Quickstart

import org.slf4j.LoggerFactory;/*** Simple Quickstart application showing how to use Shiro's API.** @since 0.9 RC2*/
public class Quickstart {//日志private static final transient Logger log = LoggerFactory.getLogger(Quickstart.class);public static void main(String[] args) {// The easiest way to create a Shiro SecurityManager with configured// realms, users, roles and permissions is to use the simple INI config.// We'll do that by using a factory that can ingest a .ini file and// return a SecurityManager instance:// Use the shiro.ini file at the root of the classpath// (file: and url: prefixes load from files and urls respectively):Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");SecurityManager securityManager = factory.getInstance();// for this simple example quickstart, make the SecurityManager// accessible as a JVM singleton.  Most applications wouldn't do this// and instead rely on their container configuration or web.xml for// webapps.  That is outside the scope of this simple quickstart, so// we'll just do the bare minimum so you can continue to get a feel// for things.SecurityUtils.setSecurityManager(securityManager);// Now that a simple Shiro environment is set up, let's see what you can do:// get the currently executing user://获取当前的用户对象  SubjectSubject currentUser = SecurityUtils.getSubject();// Do some stuff with a Session (no need for a web or EJB container!!!)//通过当前对象获取当前用户的SessionSession session = currentUser.getSession();session.setAttribute("someKey", "aValue");//将aValue的session保存在someKey中String value = (String) session.getAttribute("someKey");if (value.equals("aValue")) {log.info("Subject==》session [" + value + "]");}// let's login the current user so we can check against roles and permissions://判断当前的用户是否被认证if (!currentUser.isAuthenticated()) {//Token 令牌UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");token.setRememberMe(true);try {currentUser.login(token); //执行 登录操作} catch (UnknownAccountException uae) {//未知账号log.info("There is no user with username of " + token.getPrincipal());} catch (IncorrectCredentialsException ice) {//密码错误log.info("Password for account " + token.getPrincipal() + " was incorrect!");} catch (LockedAccountException lae) {  //锁定账号log.info("The account for username " + token.getPrincipal() + " is locked.

" +"Here are the keys - have fun!");} else {log.info("Sorry, you aren't allowed to drive the 'eagle5' winnebago!");}//all done - log out!//注销currentUser.logout();//结束System.exit(0);}
}

这些功能在Spring-Secutiry都有

//获取当前的用户对象  Subject
Subject currentUser = SecurityUtils.getSubject();//通过当前对象获取当前用户的SessionSession session = currentUser.getSession();//判断当前的用户是否被认证currentUser.isAuthenticated()//获取当前用户信息currentUser.getPrincipal()//测试角色  判断当前用户是什么角色currentUser.hasRole("schwartz")currentUser.isPermitted("lightsaber:wield")//注销
currentUser.logout();

6、SpringBoot整合Shiro环境搭建

导入相关依赖

7、shiro实现登录拦截

package com.kk.config;import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>Title</title>
</head>
<body>
<h1>登陆</h1>
<hr>
<form action=""><p>用户名:<input type="text" name="username"></p><p>密码:<input type="text" name="password"></p><p><input type="submit"></p></form>
</body>
</html>

MyController

@RequestMapping("/toLogin")
public String toLogin(){return "login";
}

8、Shiro实现用户认证

MyController

@RequestMapping("/login")
public String login(String username,String password,Model model){//获取当前的用户Subject subject = SecurityUtils.getSubject();//封装登陆用户的登陆数据UsernamePasswordToken token = new UsernamePasswordToken(username, password);try{subject.login(token);//执行登陆方法，如果没有异常就说明okreturn "index";}catch (UnknownAccountException e){//用户名不存在model.addAttribute("msg","用户名错误");return "login";}catch (IncorrectCredentialsException e){//密码不存在model.addAttribute("msg","密码错误");return "login";}}

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head><meta charset="UTF-8"><title>Title</title>
</head>
<body>
<h1>登陆</h1>
<hr>
<p th:text="${msg}" style="color: red;"></p>
<form th:action="@{/login}"><p>用户名:<input type="text" name="username"></p><p>密码:<input type="text" name="password"></p><p><input type="submit"></p></form>
</body>
</html>

UserRealm

//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {System.out.println("执行了=》认证doGetAuthenticationInfo");//用户名 密码 ---数据库String name="root";String password="123456";UsernamePasswordToken userToken = (UsernamePasswordToken) token;if (!userToken.getUsername().equals(name)){return null;//抛出异常UnknownAccountException}//密码认证  shiroreturn new SimpleAuthenticationInfo("",password,"");}

9、Shiro整合Mybatis

导入依赖

<!--        连接数据库--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.2.6</version></dependency>
<!--        引入mybatis-springboot--><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>2.2.0</version></dependency>

2.连接数据库application.yml

spring:datasource:username: rootpassword: 981204#?serverTimezone=UTC解决时区的报错url: jdbc:mysql://localhost:3306/mybatis?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8driver-class-name: com.mysql.jdbc.Drivertype: com.alibaba.druid.pool.DruidDataSource#Spring Boot 默认是不注入这些属性值的，需要自己绑定#druid 数据源专有配置initialSize: 5minIdle: 5maxActive: 20maxWait: 60000timeBetweenEvictionRunsMillis: 60000minEvictableIdleTimeMillis: 300000validationQuery: SELECT 1 FROM DUALtestWhileIdle: truetestOnBorrow: falsetestOnReturn: falsepoolPreparedStatements: true#配置监控统计拦截的filters，stat:监控统计、log4j：日志记录、wall：防御sql注入#如果允许时报错  java.lang.ClassNotFoundException: org.apache.log4j.Priority#则导入 log4j 依赖即可，Maven 地址： https://mvnrepository.com/artifact/log4j/log4jfilters: stat,wall,log4jmaxPoolPreparedStatementPerConnectionSize: 20useGlobalDataSourceStat: trueconnectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

3.设置application.properties

# 整合mybatis
mybatis.type-aliases-package=com.kk.pojo
mybatis.mapper-locations=classpath:mapper/*.xml

4.实体类

package com.kk.pojo;public class User {private int id;private String name;private String pwd;public User() {}public User(int id, String name, String pwd) {this.id = id;this.name = name;this.pwd = pwd;}public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPwd() {return pwd;}public void setPwd(String pwd) {this.pwd = pwd;}@Overridepublic String toString() {return "User{" +"id=" + id +", name='" + name + '\'' +", pwd='" + pwd + '\'' +'}';}
}

5.UserMapper

package com.kk.mapper;import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;@Repository
@Mapper
public class UserMapper {public User queryUserByName(String name);
}

6.UserMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.kk.mapper.UserMapper"><select id="queryUserByName" resultType="User">select * from mybatis.user where name = #{name}</select></mapper>

7.UserService

public interface UserService {public User queryUserByName(String name);
}

8.UserServiceImpl

package com.kk.service;import org.springframework.stereotype.Service;@Service
public class UserServiceImp implements UserService{@AutowiredUserMapper userMapper;@Overridepublic User queryUserByName(String name) {return userMapper.queryUserByName(name);}
}

9.测试查出对应User

@SpringBootTest
class ShiroSpringbootApplicationTests {@AutowiredUserServiceImpl userService;@Testvoid contextLoads() {System.out.println(userService.queryUserByName("雏田"));}
}

10、测试成功后将数据绑定到安全配置中，再次启动配置

package com.kk.config;import com.kk.pojo.User;
import com.kk.service.UserService;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;//自定义的 UserRealm         extends AuthorizingRealm
public class UserRealm extends AuthorizingRealm {@AutowiredUserService userService;//授权@Overrideprotected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {System.out.println("执行了=》授权doGetAuthorizationInfo");return null;}//认证@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {System.out.println("执行了=》认证doGetAuthenticationInfo");UsernamePasswordToken userToken = (UsernamePasswordToken) token;//连接真实数据库User user = userService.queryUserByName(userToken.getUsername());if (user==null){ //没有这个用户return null; //抛出异常UnknownAccountException}//密码认证  shiro//可以加密 MD5加密 MD5盐值加密return new SimpleAuthenticationInfo("",user.getPwd(),"");}
}

10、Shiro请求授权实现

1、授权正常的情况下，没有授权会跳转到未授权页面

package com.kk.config;import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;import java.util.LinkedHashMap;
import java.util.Map;@Configuration
public class ShiroConfig {//ShiroFilterFactoryBean:3@Beanpublic ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager) {ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();//设置安全管理器bean.setSecurityManager(defaultWebSecurityManager);/*anon:无需认 证就可以访问authc:必须认证了 才能让问user:.必须拥有 记住我功能才能用perms:拥有对某个资源的权限才能访间:role:拥有某 个角色权限才能访问*/Map<String, String> filterMap = new LinkedHashMap<>();//授权,正常的情况下，没有授权会跳转到未授权页面filterMap.put("/user/add", "perms[user:add]");filterMap.put("/user/update", "perms[user:update]");//第二个为权限，只有persm=user:add/user:update] 才可能进入相应的页面filterMap.put("/user/*", "authc");//filterMap.put("/user/add", "authc");//filterMap.put("/user/update", "authc");bean.setFilterChainDefinitionMap(filterMap);//设置获录的请求bean.setLoginUrl("/toLogin");//未授权页面bean. setUnauthorizedUrl("/noauth");return bean;}//Dafaul tWebSecurityManager:2@Bean(name = "securityManager")public DefaultWebSecurityManager getDefaultwebSecurityManager(@Qualifier("userRealm") UserRealm userRealm) {DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();//关联UserReaLmsecurityManager.setRealm(userRealm);return securityManager;}//创建UserRealm对象，需要自定义类:1@Beanpublic UserRealm userRealm() {return new UserRealm();}
}

controller

@RequestMapping("/noauth")
@ResponseBody
public String unauthorized() {return "未经授权无法访问此页面";
}

2、授予可以访问的权限

package com.kk.config;import com.kk.pojo.User;
import com.kk.service.UserService;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;public class UserRealm extends AuthorizingRealm {@AutowiredUserService userService;@Overrideprotected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {System.out.println("执行了=》授权doGetAuthorizationInfo");//SimpleAuthorizationInfoSimpleAuthorizationInfo info = new SimpleAuthorizationInfo();info.addStringPermission("user:add");return info;}@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {System.out.println("执行了=》验证doGetAuthorizationInfo");UsernamePasswordToken userToken = (UsernamePasswordToken) token;//连接真实的数据库User user = userService.queryUserByName(userToken.getUsername());if (user == null) { //没有这个用户return null; //UnknownAccountException}//可以加密: MD5: e10adc3949ba59abbe56e057f20f883e MD5 盐值加密: e10adc3949ba59abbe56e057f20f883eusername//密码认证, shiro 做~return new SimpleAuthenticationInfo("", user.getPwd(), "");}
}

3、一般在数据库里添加权限的字段，修改数据库，和实体类

实体类

private int id;private String name;private String pwd;private String perms;

UserRealm实现授权的分配

package com.kk.config;import com.kk.pojo.User;
import com.kk.service.UserService;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;public class UserRealm extends AuthorizingRealm {@AutowiredUserService userService;@Overrideprotected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {System.out.println("执行了=》授权doGetAuthorizationInfo");//SimpleAuthorizationInfoSimpleAuthorizationInfo info = new SimpleAuthorizationInfo();//info.addStringPermission("user:add");//拿到当登录 的这个对象Subject subject = SecurityUtils.getSubject();User currentUser = (User) subject.getPrincipal(); //拿到User对象//设置当前用户的权限info.addStringPermission(currentUser.getPerms());return info;}@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {System.out.println("执行了=》验证doGetAuthorizationInfo");UsernamePasswordToken userToken = (UsernamePasswordToken) token;//连接真实的数据库User user = userService.queryUserByName(userToken.getUsername());if (user == null) { //没有这个用户return null; //UnknownAccountException}//可以加密: MD5: e10adc3949ba59abbe56e057f20f883e MD5 盐值加密: e10adc3949ba59abbe56e057f20f883eusername//密码认证, shiro 做~return new SimpleAuthenticationInfo(user, user.getPwd(), "");}
}

3.使用shirothymeleaf

在html页面中导入

xmlns:shiro="http://www.thymeleaf.org/thymeleaf-extras-shiro

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org"xmlns:shiro="http://www.thymeleaf.org/thymeleaf-extras-shiro">
<head><meta charset="UTF-8"><title>Title</title>
</head>
<body>
<h1>首页</h1>
<p><a th:href="@{/toLogin}">登录</a>
</p>
<p th:text="${msg}"></p>
<hr>
<div shiro:hasPermission="user:add"><a th:href="@{/user/add}">add</a>
</div>
<div shiro:hasPermission="user:update"><a th:href="@{/user/update}">update</a>
</div></body>
</html>

4.测试

存在登录按钮的问题

UserRealm中添加session

@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {System.out.println("执行了=》验证doGetAuthorizationInfo");UsernamePasswordToken userToken = (UsernamePasswordToken) token;//连接真实的数据库User user = userService.queryUserByName(userToken.getUsername());if (user == null) { //没有这个用户return null; //UnknownAccountException}Subject currentSubject = SecurityUtils.getSubject();Session session = currentSubject.getSession();session.setAttribute("loginUser",user);//可以加密: MD5: e10adc3949ba59abbe56e057f20f883e MD5 盐值加密: e10adc3949ba59abbe56e057f20f883eusername//密码认证, shiro 做~return new SimpleAuthenticationInfo(user, user.getPwd(), "");}
}

index.html

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org"xmlns:shiro="http://www.thymeleaf.org/thymeleaf-extras-shiro">
<head><meta charset="UTF-8"><title>Title</title>
</head>
<body>
<h1>首页</h1>
<div th:if="${session.loginUser==null}"><a th:href="@{/toLogin}">登录</a>
</div><p th:text="${msg}"></p>
<hr>
<div shiro:hasPermission="user:add"><a th:href="@{/user/add}">add</a>
</div>
<div shiro:hasPermission="user:update"><a th:href="@{/user/update}">update</a>
</div></body>
</html>

项目结构

nInfo");
UsernamePasswordToken userToken = (UsernamePasswordToken) token;
//连接真实的数据库
User user = userService.queryUserByName(userToken.getUsername());
if (user == null) { //没有这个用户
return null; //UnknownAccountException
}

    Subject currentSubject = SecurityUtils.getSubject();Session session = currentSubject.getSession();session.setAttribute("loginUser",user);//可以加密: MD5: e10adc3949ba59abbe56e057f20f883e MD5 盐值加密: e10adc3949ba59abbe56e057f20f883eusername//密码认证, shiro 做~return new SimpleAuthenticationInfo(user, user.getPwd(), "");}
