Shiro安全框架之整合Spring框架

官方文档：http://shiro.apache.org/spring.html

要求：实现用户登录功能 （与前几章讲的一样，只不过这里整合到了Spring框架中，可以对比来看）

一、新建个maven项目

二、将需要的依赖包贴到pom中

    </dependency>
    

  </dependencies>

三、src/main/java新建dao entity controller realm service service.impl

 1、entity.User.java

package com.guo.entity;

public class User {

    private Integer id;
    private String userName;
    private String password;
    
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    
    
}

2、dao.UserDao.java

package com.guo.dao;

import java.util.Set;

import com.guo.entity.User;

public interface UserDao {

    /**
     * 通过用户名查询用户
     * @param userName
     * @return
     */
    public User getByUserName(String userName);
    
    /**
     * 通过用户名查询角色信息
     * @param userName
     * @return
     */
    public Set<String> getRoles(String userName);
    
    /**
     * 通过用户名查询权限信息
     * @param userName
     * @return
     */
    public Set<String> getPermissions(String userName);
}

3、service.UserService.java

package com.guo.service;

import java.util.Set;

import com.guo.entity.User;

public interface UserService {

    /**
     * 通过用户名查询用户
     * @param userName
     * @return
     */
    public User getByUserName(String userName);
    
    /**
     * 通过用户名查询角色信息
     * @param userName
     * @return
     */
    public Set<String> getRoles(String userName);
    
    /**
     * 通过用户名查询权限信息
     * @param userName
     * @return
     */
    public Set<String> getPermissions(String userName);
}

4、serviceimpl.UserServiceImpl

package com.guo.service.impl;

import java.util.Set;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.guo.dao.UserDao;
import com.guo.entity.User;
import com.guo.service.UserService;

@Service("userService")
public class UserServiceImpl implements UserService{

    @Resource
    private UserDao userDao;
    
    public User getByUserName(String userName) {
        return userDao.getByUserName(userName);
    }

    public Set<String> getRoles(String userName) {
        return userDao.getRoles(userName);
    }

    public Set<String> getPermissions(String userName) {
        return userDao.getPermissions(userName);
    }

}

5、controller.UserController.java

package com.guo.controller;

import javax.servlet.http.HttpServletRequest;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.guo.entity.User;



/**
 * 用户Controller层
 * @author Administrator
 *
 */
@Controller
@RequestMapping("/user")
public class UserController {

    
    /**
     * 用户登录
     * @param user
     * @param request
     * @return
     */
    @RequestMapping("/login")
    public String login(User user,HttpServletRequest request){
        Subject subject=SecurityUtils.getSubject();
        UsernamePasswordToken token=new UsernamePasswordToken(user.getUserName(), user.getPassword());
        try{
            subject.login(token);
            Session session=subject.getSession();
            System.out.println("sessionId:"+session.getId());
            System.out.println("sessionHost:"+session.getHost());
            System.out.println("sessionTimeout:"+session.getTimeout());
            session.setAttribute("info", "session的数据");
            return "redirect:/success.jsp";
        }catch(Exception e){
            e.printStackTrace();
            request.setAttribute("user", user);
            request.setAttribute("errorMsg", "用户名或密码错误！");
            return "index";
        }
    }
    

}

6、realm.MyRealm.java

package com.guo.realm;


import javax.annotation.Resource;

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
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 com.guo.entity.User;
import com.guo.service.UserService;

public class MyRealm extends AuthorizingRealm{

    @Resource
    private UserService userService;
    
    /**
     * 为当限前登录的用户授予角色和权
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        String userName=(String)principals.getPrimaryPrincipal();
        SimpleAuthorizationInfo authorizationInfo=new SimpleAuthorizationInfo();
        authorizationInfo.setRoles(userService.getRoles(userName));
        authorizationInfo.setStringPermissions(userService.getPermissions(userName));
        return authorizationInfo;
    }

    /**
     * 验证当前登录的用户
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        String userName=(String)token.getPrincipal();
            User user=userService.getByUserName(userName);
            if(user!=null){
                AuthenticationInfo authcInfo=new SimpleAuthenticationInfo(user.getUserName(),user.getPassword(),"xx");
                return authcInfo;
            }else{
                return null;                
            }
    }

}

四、在src/main/resource下建mappers.xml映射包（一些SSM配置文件也放到src/main/resource下）

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.guo.dao.UserDao">

    <resultMap type="User" id="UserResult">
        <result property="id" column="id"/>
        <result property="userName" column="userName"/>
        <result property="password" column="password"/>
    </resultMap>
    
    <select id="getByUserName" parameterType="String" resultMap="UserResult">
        select * from t_user where userName=#{userName}
    </select>
    
    <select id="getRoles" parameterType="String" resultType="String">
        select r.roleName from t_user u,t_role r where u.roleId=r.id and u.userName=#{userName}
    </select>
    
    <select id="getPermissions" parameterType="String" resultType="String">
        select p.permissionName from t_user u,t_role r,t_permission p where u.roleId=r.id and p.roleId=r.id and u.userName=#{userName}
    </select>

</mapper> 

五、Shiro.ini配置文件 被放到Spring的配置文件applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>    
<beans xmlns="http://www.springframework.org/schema/beans"    
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
