springboot+mybatis＋SpringSecurity 实现用户角色数据库管理

本文使用springboot+mybatis＋SpringSecurity 实现用户权限数据库管理

实现用户和角色用数据库存储，而资源(url)和权限的对应采用硬编码配置。 也就是角色可以访问的权限通过硬编码控制。角色和用户的关系通过数据库配置控制

本文用户和角色的关系是多对多的关系。

SpringSecurity 验证帐号密码

首先在usernamePasswordAuthenticationFilter中来拦截登录请求，并调用AuthenticationManager。

AuthenticationManager调用Provider，provider调用userDetaisService来根据username获取真实的数据库信息。 
最终验证帐号密码的类是org.springframework.security.authentication.dao.DaoAuthenticationProvider这个流程虽然没多么复杂，但是花费我不少时间给理解到了。。。

本文结构： 
1：数据库表设计 
2：springboot＋mybatis 配置 
3：业务实现 
4：springSecurity整合 
5：页面实现 
6：测试验证

完整目录结构如下：

---

1：数据库表设计

数据库表有 用户表，角色表，用户角色关系表三张表：

插入数据

insert into SYS_USER (id,username, password) values (1,'admin', 'admin');
insert into SYS_USER (id,username, password) values (2,'abel', 'abel');

insert into SYS_ROLE(id,name) values(1,'ROLE_ADMIN');
insert into SYS_ROLE(id,name) values(2,'ROLE_USER');

insert into SYS_ROLE_USER(SYS_USER_ID,ROLES_ID) values(1,1);
insert into SYS_ROLE_USER(SYS_USER_ID,ROLES_ID) values(2,2);

2：springboot＋mybatis 配置

2.1 springboot 配置

新建maven 工程，pom.xml 内容如下：

3：业务实现

3.1 java bean

有三个bean ，sysuser（用户），sysrole（角色）msg（信息，用于和页面传递信息使用）

sysuser.java

package com.us.example.domain;

import java.util.List;

/**
 * Created by yangyibo on 17/1/17.
 */

public class SysUser {
    private Integer id;
    private String username;
    private String password;

    private List<SysRole> roles;

    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;
    }

    public List<SysRole> getRoles() {
        return roles;
    }

    public void setRoles(List<SysRole> roles) {
        this.roles = roles;
    }
}

SysRole.java

package com.us.example.domain;

/**
 * Created by yangyibo on 17/1/17.
 */

public class SysRole {

    private Integer id;
    private String name;
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

Msg.java

package com.us.example.domain;

/**
 * Created by yangyibo on 17/1/17.
 */

    public class Msg {
        private String title;
        private String content;
        private String etraInfo;

        public Msg(String title, String content, String etraInfo) {
            super();
            this.title = title;
            this.content = content;
            this.etraInfo = etraInfo;
        }
        public String getTitle() {
            return title;
        }
        public void setTitle(String title) {
            this.title = title;
        }
        public String getContent() {
            return content;
        }
        public void setContent(String content) {
            this.content = content;
        }
        public String getEtraInfo() {
            return etraInfo;
        }
        public void setEtraInfo(String etraInfo) {
            this.etraInfo = etraInfo;
        }

    }

3.2 dao 层实现

UserDao.java

package com.us.example.dao;

import com.us.example.config.MyBatisRepository;
import com.us.example.domain.SysUser;

public interface UserDao {
    public SysUser findByUserName(String username);
}

mapper.xml

在src/resource目录下新建 mapper 文件夹，在mapper文件夹下新建UserDaomapper.xml文件内容如下；

<?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.us.example.dao.UserDao">
    <resultMap id="userMap" type="com.us.example.domain.SysUser">
        <id property="id" column="ID"/>
        <result property="username" column="username"/>
        <result property="password" column="PASSWORD"/>
        <collection property="roles" ofType="com.us.example.domain.SysRole">
            <result column="name" property="name"/>
        </collection>

    </resultMap>
    <select id="findByUserName" parameterType="String" resultMap="userMap">
        select u.*
        ,r.name
        from Sys_User u
        LEFT JOIN sys_role_user sru on u.id= sru.Sys_User_id
        LEFT JOIN Sys_Role r on sru.Sys_Role_id=r.id
        where username= #{username}
    </select>
</mapper>

由于本例较为简单，所以就去掉了service 层。

4：springSecurity整合

添加springSecurity 配置，在com.us.example.config 包下，新建 
WebSecurityConfig.java 配置文件，用于管控登录访问权限

可以在WebSecurityConfig 中 使用                .antMatchers("/admin/**").hasRole("ROLE_ADMIN")

将url 权限分配给角色

WebSecurityConfig.java

package com.us.example.config;

import com.us.example.security.CustomUserService;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
/**
 * Created by yangyibo on 17/1/18.
 */
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    UserDetailsService customUserService(){ //注册UserDetailsService 的bean
        return new CustomUserService();
    }
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(customUserService()); //user Details Service验证

    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .anyRequest().authenticated() //任何请求,登录后可以访问
                .and()
                .formLogin()
                .loginPage("/login")
                .failureUrl("/login?error")
                .permitAll() //登录页面用户任意访问
                .and()
                .logout().permitAll(); //注销行为任意访问


    }
}

CustomUserService.java

新建 CustomUserService 用于将用户权限交给 springsecurity 进行管控；

package com.us.example.security;

import com.us.example.dao.UserDao;
import com.us.example.domain.SysRole;
import com.us.example.domain.SysUser;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;

import java.util.ArrayList;
import java.util.List;

/**
 * Created by yangyibo on 17/1/18.
 */
@Service
public class CustomUserService implements UserDetailsService { //自定义UserDetailsService 接口

    @Autowired
    UserDao userDao;

    @Override
    public UserDetails loadUserByUsername(String username) { //重写loadUserByUsername 方法获得 userdetails 类型用户

        SysUser user = userDao.findByUserName(username);
        if(user == null){
            throw new UsernameNotFoundException("用户名不存在");
        }
        List<SimpleGrantedAuthority> authorities = new ArrayList<>();
        //用于添加用户的权限。只要把用户权限添加到authorities 就万事大吉。
        for(SysRole role:user.getRoles())
        {
            authorities.add(new SimpleGrantedAuthority(role.getName()));
            System.out.println(role.getName());
        }
        return new org.springframework.security.core.userdetails.User(user.getUsername(),
                user.getPassword(), authorities);
    }
}

5：页面实现

在src/resource 目录下新建static/css 目录，并放入js 文件 bootstrap.min.css （此文件在本文源码里有， 源码地址在文章底端）

在src/resource目录下新建 templates 文件夹，里面编写静态页面

login.html

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta content="text/html;charset=UTF-8"/>
<title>登录页面</title>
<link rel="stylesheet" th:href="@{css/bootstrap.min.css}"/>
<style type="text/css">
    body {
  padding-top: 50px;
}
.starter-template {
  padding: 40px 15px;
  text-align: center;
}
</style>
</head>
<body>

     <nav class="navbar navbar-inverse navbar-fixed-top">
      <div class="container">
        <div class="navbar-header">
          <a class="navbar-brand" href="#">Spring Security演示</a>
        </div>
        <div id="navbar" class="collapse navbar-collapse">
          <ul class="nav navbar-nav">
           <li><a th:href="@{/}"> 首页 </a></li>

          </ul>
        </div><!--/.nav-collapse -->
      </div>
    </nav>
     <div class="container">

      <div class="starter-template">
       <p th:if="${param.logout}" class="bg-warning">已成功注销</p><!-- 1 -->
            <p th:if="${param.error}" class="bg-danger">有错误，请重试</p> <!-- 2 -->
            <h2>使用账号密码登录</h2>
            <form name="form" th:action="@{/login}" action="/login" method="POST"> <!-- 3 -->
                <div class="form-group">
                    <label for="username">账号</label>
                    <input type="text" class="form-control" name="username" value="" placeholder="账号" />
                </div>
                <div class="form-group">
                    <label for="password">密码</label>
                    <input type="password" class="form-control" name="password" placeholder="密码" />
                </div>
                <input type="submit" id="login" value="Login" class="btn btn-primary" />
            </form>
      </div>
    </div>  
</body>
</html>

home.html

注意：本文是通过home.html  的sec:authorize="hasRole('ROLE_ADMIN') 实现角色权限管理

        </form>
      </div>

    </div>

</body>
</html>

6. controller

在com.us.example.controller 包下 编写控制器 HomeController.java

HomeController.java

package com.us.example.controller;

import com.us.example.domain.Msg;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * Created by yangyibo on 17/1/18.
 */
@Controller
public class HomeController {

    @RequestMapping("/")
    public String index(Model model){
        Msg msg =  new Msg("测试标题","测试内容","额外信息，只对管理员显示");
        model.addAttribute("msg", msg);
        return "home";
    }
}

WebMvcConfig.java

springMVC 配置，注册访问 /login 转向 login.html 页面

package com.us.example.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
/**
 * Created by yangyibo on 17/1/18.
 */
@Configuration

public class WebMvcConfig extends WebMvcConfigurerAdapter{

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/login").setViewName("login");
    }
}

7：测试验证

启动项目 在浏览器输入 http://localhost:8080/ 进行测试：

首先使用 admin 帐号登录

结果：

然后注销，使用 abel 普通用户登录结果如下：
