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：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

在com.us.example 目录下新建 Application.java 启动入口
package com.us.example;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import static org.springframework.boot.SpringApplication.run;
/**
* Created by yangyibo on 17/1/17.
*/
@ComponentScan(basePackages ="com.us.example")
@SpringBootApplication
public class Application {
public static void main(String[] args) {
ConfigurableApplicationContext run = run(Application.class, args);
}
}
在src/resource/目录下新建application.properties 配置文件，配置spingboot 的配置信息：
ms.db.driverClassName=com.mysql.jdbc.Driver
ms.db.url=jdbc:mysql://localhost:3306/cache?characterEncoding=utf-8&useSSL=false
ms.db.username=root
ms.db.password=admin
ms.db.maxActive=500
logging.level.org.springframework.security= INFO
spring.thymeleaf.cache=false
2.2 mybatis 配置
在com.us.example.config 包下新建 以下配置文件，
DBconfig.java （配置数据源）
package com.us.example.config;
import java.beans.PropertyVetoException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import com.mchange.v2.c3p0.ComboPooledDataSource;
/**
* Created by yangyibo on 17/1/18.
*/
@Configuration
public class DBconfig {
@Autowired
private Environment env;
@Bean(name="dataSource")
public ComboPooledDataSource dataSource() throws PropertyVetoException {
ComboPooledDataSource dataSource = new ComboPooledDataSource();
dataSource.setDriverClass(env.getProperty("ms.db.driverClassName"));
dataSource.setJdbcUrl(env.getProperty("ms.db.url"));
dataSource.setUser(env.getProperty("ms.db.username"));
dataSource.setPassword(env.getProperty("ms.db.password"));
dataSource.setMaxPoolSize(20);
dataSource.setMinPoolSize(5);
dataSource.setInitialPoolSize(10);
dataSource.setMaxIdleTime(300);
dataSource.setAcquireIncrement(5);
dataSource.setIdleConnectionTestPeriod(60);
return dataSource;
}
}
MyBatisConfig.java （扫描mapper.xml文件）
package com.us.example.config;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import javax.sql.DataSource;
@Configuration
@ComponentScan
public class MyBatisConfig {
@Autowired
private DataSource dataSource;
@Bean(name = "sqlSessionFactory")
public SqlSessionFactoryBean sqlSessionFactory(ApplicationContext applicationContext) throws Exception {
SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
sessionFactory.setDataSource(dataSource);
// sessionFactory.setPlugins(new Interceptor[]{new PageInterceptor()});
sessionFactory.setMapperLocations(applicationContext.getResources("classpath*:mapper/*.xml"));
return sessionFactory;
}
}
MyBatisScannerConfig.java (dao 扫描器)
package com.us.example.config;
import org.mybatis.spring.mapper.MapperScannerConfigurer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class MyBatisScannerConfig {
@Bean
public MapperScannerConfigurer MapperScannerConfigurer() {
MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
mapperScannerConfigurer.setBasePackage("com.us.example.dao");
mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory");
return mapperScannerConfigurer;
}
}
TransactionConfig.java (开启事物管理)
package com.us.example.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.TransactionManagementConfigurer;
import javax.sql.DataSource;
@Configuration
@ComponentScan
public class TransactionConfig implements TransactionManagementConfigurer{
@Autowired
private DataSource dataSource;
@Bean(name = "transactionManager")
@Override
public PlatformTransactionManager annotationDrivenTransactionManager() {
return new DataSourceTransactionManager(dataSource);
}
}
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);
}
1
2
3
4
5
6
7
8
9
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")
1
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
1
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org"
xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">
<head>
<meta content="text/html;charset=UTF-8"/>

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">
<h1 th:text="${msg.title}"></h1>
<p class="bg-primary" th:text="${msg.content}"></p>
<div sec:authorize="hasRole('ROLE_ADMIN')"> <!-- 用户类型为ROLE_ADMIN 显示 -->
<p class="bg-info" th:text="${msg.etraInfo}"></p>
</div>
<div sec:authorize="hasRole('ROLE_USER')"> <!-- 用户类型为 ROLE_USER 显示 -->
<p class="bg-info">无更多信息显示</p>
</div>
<form th:action="@{/logout}" method="post">
<input type="submit" class="btn btn-primary" value="注销"/>
</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;
/**

*/
@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：
