3.配置文件db.properties ; shiro-spring.xml ; spring-mvc.xml

4MyRealm.java
package com.ym.shiro;
import com.ym.entity.Permission;
import com.ym.entity.Role;
import com.ym.entity.User;
import com.ym.service.IUserService;
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 javax.annotation.Resource;
import java.util.List;
public class MyRealm extends AuthorizingRealm {
@Resource
private IUserService userService;
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
SimpleAuthorizationInfo info=new SimpleAuthorizationInfo();
String username = getAvailablePrincipal(principalCollection).toString();
List<Role> roles = userService.getAllRolesByUsername(username);
for (Role role : roles) {
info.addRole(role.getRname());
}
List<Permission> permissions = userService.getAllPermissionsByUsername(username);
for (Permission permission : permissions) {
info.addStringPermission(permission.getPname());
}
return info;
}
//认证
@Override

User u = userService.login(username, pass);
if (u!=null && u.getUid()!=0){
String name = getName();

}
return info;
}
}
5.entity层的Javabean
- User.java : 用户
package com.ym.entity;
import lombok.Data;
import java.io.Serializable;
import java.util.Set;
@Data
public class User implements Serializable {
private static final long serialVersionUID = 617289138502785533L;
private Integer uid;
private String username;
private String password;
private String tel;
private String addr;
private Set<Role> rs;
}
- Role.java : 角色
package com.ym.entity;
import lombok.Data;
import java.io.Serializable;
import java.util.Set;
@Data
public class Role implements Serializable {
private static final long serialVersionUID = -74163700661732397L;
private Integer rid;
private String rname;
private String rdesc;
private Set<Permission> ps;
}
- Permission.java : 权限
package com.ym.entity;
import lombok.Data;
import java.io.Serializable;
@Data
public class Permission implements Serializable {
private static final long serialVersionUID = 581645870054218482L;
private Integer pid;
private String pname;
private String pdesc;
}
6.dao层接口IUserDao
package com.ym.dao;
import com.ym.entity.Permission;
import com.ym.entity.Role;
import com.ym.entity.User;
import java.util.List;
public interface IUserDao {
User login(User user);
List<Role> getAllRolesByUsername(String username);
List<Permission> getAllPermissionsByUsername(String username);
}
7.与dao层接口对应的mapper文件
- UserMapper.xml
<?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.ym.dao.IUserDao">
<select id="login" resultType="User">
select * from user where username=#{username} and password=#{password}
</select>
<select id="getAllRolesByUsername" resultType="Role">
select r.* from user u
inner JOIN user_role ur on u.uid = ur.uid
inner join Role r on r.rid=ur.rid
where u.username=#{username};
</select>
<select id="getAllPermissionsByUsername" resultType="Permission">
select p.* from user u
inner JOIN user_role ur on u.uid = ur.uid
inner join Role r on r.rid=ur.rid
INNER JOIN role_perms rp on r.rid = rp.rid
INNER JOIN permission p on p.pid = rp.pid
where u.username=#{username};
</select>
</mapper>
8.service层接口与实现类
- 接口 IUserService.java
package com.ym.service;
import com.ym.entity.Permission;
import com.ym.entity.Role;
import com.ym.entity.User;
import java.util.List;
public interface IUserService {
User login(String username, String pass);
List<Role> getAllRolesByUsername(String username);
List<Permission> getAllPermissionsByUsername(String username);
}
- 实现类UserServiceImpl.java
package com.ym.service.impl;
import com.ym.dao.IUserDao;
import com.ym.entity.Permission;
import com.ym.entity.Role;
import com.ym.entity.User;
import com.ym.service.IUserService;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
import java.util.List;
@Service
public class UserServiceImpl implements IUserService {
@Resource
private IUserDao userDao;
@Override
public User login(String username, String pass) {
User u=new User();
u.setUsername(username);
u.setPassword(pass);
return userDao.login(u);
}
@Override
public List<Role> getAllRolesByUsername(String username) {
return userDao.getAllRolesByUsername(username);
}
@Override
public List<Permission> getAllPermissionsByUsername(String username) {
return userDao.getAllPermissionsByUsername(username);
}
}
9.controller层UserService.java
package com.ym.controller;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
@Controller
public class UserController {
@PostMapping("/login")
public String login(@RequestParam("username") String username,@RequestParam("password") String password){
Subject subject = SecurityUtils.getSubject();
UsernamePasswordToken token=new UsernamePasswordToken(username,password);
try {
subject.login(token);
return "main.jsp";
} catch (AuthenticationException e) {
e.printStackTrace();
return "index.html";
}
}
}
10.前端页面
-
登陆成功之后,看是否拥有访问delete.jsp ; select.jsp ; manager.jsp ; guest.jsp的权限
-
index.html : 匿名用户访问
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>index</title>
</head>
<body>
<h1>this is index page.</h1>

password:<input type="text" name="password" /><p />
<input type="submit" value="submit" /><p />
</form>
</body>
</html>
- main.jsp : 认证之后的用户才可以访问
<%@ page contentType="text/html;charset=UTF-8" language="java" %>

- manager.jsp : 用户角色是manager的用户才可以访问
<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<head>
<title>guest</title>
</head>
<body>
<h1>i am a guest</h1>
</body>
