springboot+mybatis＋SpringSecurity 实现用户角色数据库管理(一)

时间：2021-11-11 02:10:45

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="/POM/4.0.0"xmlns:xsi="/2001/XMLSchema-instance"xsi:schemaLocation="/POM/4.0.0 /xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.us</groupId><artifactId>springboot-security</artifactId><version>1.0-SNAPSHOT</version><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>1.3.0.RELEASE</version></parent><properties><start-class>com.us.Application</start-class><piler.target>1.8</piler.target><piler.source>1.8</piler.source><mybatis.version>3.2.7</mybatis.version><mybatis-spring.version>1.2.2</mybatis-spring.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency><dependency><groupId>org.thymeleaf.extras</groupId><artifactId>thymeleaf-extras-springsecurity4</artifactId></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>6.0.5</version></dependency><dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.5.2</version><exclusions><exclusion><groupId>commons-logging</groupId><artifactId>commons-logging</artifactId></exclusion></exclusions></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>${mybatis.version}</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>${mybatis-spring.version}</version></dependency></dependencies></project>

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.ponentScan;import static org.springframework.boot.SpringApplication.run;/*** Created by yangyibo on 17/1/17.*/@ComponentScan(basePackages ="com.us.example")@SpringBootApplicationpublic 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.Driverms.db.url=jdbc:mysql://localhost:3306/cache?characterEncoding=utf-8&useSSL=falsems.db.username=rootms.db.password=adminms.db.maxActive=.springframework.security= INFOspring.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.boPooledDataSource;/*** Created by yangyibo on 17/1/18.*/@Configurationpublic class DBconfig {@Autowiredprivate 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.ponentScan;import org.springframework.context.annotation.Configuration;import javax.sql.DataSource;@Configuration@ComponentScanpublic class MyBatisConfig {@Autowiredprivate 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;@Configurationpublic class MyBatisScannerConfig {@Beanpublic 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.ponentScan;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@ComponentScanpublic class TransactionConfig implements TransactionManagementConfigurer{@Autowiredprivate DataSource dataSource;@Bean(name = "transactionManager")@Overridepublic 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);}

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 "-////DTD Mapper 3.0//EN" "/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.namefrom Sys_User uLEFT JOIN sys_role_user sru on u.id= sru.Sys_User_idLEFT JOIN Sys_Role r on sru.Sys_Role_id=r.idwhere 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@EnableWebSecuritypublic class WebSecurityConfig extends WebSecurityConfigurerAdapter {@BeanUserDetailsService customUserService(){ //注册UserDetailsService 的beanreturn new CustomUserService();}@Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {auth.userDetailsService(customUserService()); //user Details Service验证}@Overrideprotected 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.*/@Servicepublic class CustomUserService implements UserDetailsService { //自定义UserDetailsService 接口@AutowiredUserDao userDao;@Overridepublic 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

<!DOCTYPE html><html xmlns:th=""><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></div></nav><div class="container"><div class="starter-template"><p th:if="${param.logout}" class="bg-warning">已成功注销</p><p th:if="${param.error}" class="bg-danger">有错误，请重试</p> <h2>使用账号密码登录</h2><form name="form" th:action="@{/login}" action="/login" method="POST"> <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

<!DOCTYPE html><html xmlns:th="" xmlns:sec="/thymeleaf-extras-springsecurity4"><head><meta content="text/html;charset=UTF-8"/><title sec:authentication="name"></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></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')"> <p class="bg-info" th:text="${msg.etraInfo}"></p></div> <div sec:authorize="hasRole('ROLE_USER')"> <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.*/@Controllerpublic 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.*/@Configurationpublic class WebMvcConfig extends WebMvcConfigurerAdapter{@Overridepublic void addViewControllers(ViewControllerRegistry registry) {registry.addViewController("/login").setViewName("login");}}
