SpringBoot中用SpringSecurity实现用户登录并返回其拥有哪些角色 - 那二傻子

公告

SpringBoot中用SpringSecurity实现用户登录并返回其拥有哪些角色

注：在使用springsecurity之前我们用普通的登录方式

　　1、前端发来登录请求会带上username，password

　　2、后端根据username去数据库查询用户，查不到表示用户不存在，查到了再拿password去和数据库进行比对

　　3、如果比对一样把它存入session，后续实行任何操作都先从session中先判断user存不存在

其实一直以来我对用户登录的理解就是这么简单，然后我发现有很多地方的登录都五花八门，方式多了，自己也就会变得

有点糊涂，所以我在这里就使用博客形式来理清一下思路，如果用springsecurity的话这些步骤其实框架都给我们做了，这也是这篇博客的意义所在...

下面就使用springsecurity来进行登录，有人会问为什么不用shiro来实现，其实springsecurity这个技术也存在很多年了，并不是一个

新技术了，如果使用SSM框架确实配合shiro会香一点，但是在springboot中使用springsecurity会更方便，因为很多事情boot都帮我们做了

下面就来和我一起coding吧....

一、创建hr(user)表、role(角色)表、hr_role(用户角色关联表)

 1 CREATE TABLE `hr` (
 2   `id` int(11) NOT NULL AUTO_INCREMENT COMMENT 'hrID',
 3   `name` varchar(32) DEFAULT NULL COMMENT '姓名',
 4   `phone` char(11) DEFAULT NULL COMMENT '手机号码',
 5   `telephone` varchar(16) DEFAULT NULL COMMENT '住宅电话',
 6   `address` varchar(64) DEFAULT NULL COMMENT '联系地址',
 7   `enabled` tinyint(1) DEFAULT '1',
 8   `username` varchar(255) DEFAULT NULL COMMENT '用户名',
 9   `password` varchar(255) DEFAULT NULL COMMENT '密码',
10   `userface` varchar(255) DEFAULT NULL,
11   `remark` varchar(255) DEFAULT NULL,
12   PRIMARY KEY (`id`)
13 ) ENGINE=InnoDB AUTO_INCREMENT=13 DEFAULT CHARSET=utf8

1 CREATE TABLE `role` (
2   `id` INT(11) NOT NULL AUTO_INCREMENT,
3   `name` VARCHAR(64) DEFAULT NULL,
4   `nameZh` VARCHAR(64) DEFAULT NULL COMMENT '角色名称',
5   PRIMARY KEY (`id`)
6 ) ENGINE=INNODB AUTO_INCREMENT=22 DEFAULT CHARSET=utf8

 1 CREATE TABLE `hr_role` (
 2   `id` INT(11) NOT NULL AUTO_INCREMENT,
 3   `hrid` INT(11) DEFAULT NULL,
 4   `rid` INT(11) DEFAULT NULL,
 5   PRIMARY KEY (`id`),
 6   KEY `rid` (`rid`),
 7   KEY `hr_role_ibfk_1` (`hrid`),
 8   CONSTRAINT `hr_role_ibfk_1` FOREIGN KEY (`hrid`) REFERENCES `hr` (`id`) ON DELETE CASCADE,
 9   CONSTRAINT `hr_role_ibfk_2` FOREIGN KEY (`rid`) REFERENCES `role` (`id`)
10 ) ENGINE=INNODB AUTO_INCREMENT=76 DEFAULT CHARSET=utf8

二、先不急做其他的，可以先测试一下，下面我随便写了个controller【创建springboot工程时记得加上springsecurity依赖】

 1 package org.yybb.securitylogin.controller;
 2 
 3 import org.springframework.web.bind.annotation.GetMapping;
 4 import org.springframework.web.bind.annotation.RestController;
 5 
 6 /**
 7  * @Author: Ben
 8  * @CreateTime: 2020-03-12 06:00
 9  */
10 @RestController
11 public class HelloController {
12     @GetMapping("/hello")
13     public String hello() {
14         return "hello ";
15     }
16 }

三、访问hello

他会自动跳转到springsecurity的登录页，然后我们就行登录，默认用户名是user密码会在控制台随机打印出来的，然后登录过后就能访问了

只要引入security依赖就会把所以接口保护起来，下面我们连接上数据库使用

四、创建实体类

注意：使用springsecurity用户类必须实现UserDetail

  1 package org.yybb.securitylogin.model;
  2 
  3 import org.springframework.security.core.GrantedAuthority;
  4 import org.springframework.security.core.userdetails.UserDetails;
  5 
  6 import java.util.Collection;
  7 import java.util.List;

五、创建service和mapper和mapper.xml[service必须实现userdetaillservice接口]

 1 package org.yybb.securitylogin.service;
 2 
 3 import org.springframework.beans.factory.annotation.Autowired;
 4 import org.springframework.security.core.userdetails.UserDetails;
 5 import org.springframework.security.core.userdetails.UserDetailsService;
 6 import org.springframework.security.core.userdetails.UsernameNotFoundException;
 7 import org.springframework.stereotype.Service;
 8 import org.yybb.securitylogin.mapper.HrMapper;
 9 import org.yybb.securitylogin.model.Hr;
10 
11 /**
12  * @Author: Ben
13  * @CreateTime: 2020-03-12 06:17
14  */
15 @Service
16 public class HrService implements UserDetailsService {
17     @Autowired
18     HrMapper hrMapper;
19     @Override
20     public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
21         Hr hr = hrMapper.loadUserByUsername(username);
22         if (hr==null){
23             throw new UsernameNotFoundException("用户不存在");
24         }
25         return hr;
26     }
27 }

 1 package org.yybb.securitylogin.mapper;
 2 
 3 import org.apache.ibatis.annotations.Mapper;
 4 import org.yybb.securitylogin.model.Hr;
 5 
 6 /**
 7  * @Author: Ben
 8  * @CreateTime: 2020-03-12 06:19
 9  */
10 @Mapper
11 public interface HrMapper {
12 
13     Hr loadUserByUsername(String username);
14 }

 1 <?xml version="1.0" encoding="UTF-8" ?>
 2 <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
 3 <mapper namespace="org.yybb.securitylogin.mapper.HrMapper">
 4     <resultMap id="BaseResultMap" type="org.yybb.securitylogin.model.Hr">
 5         <id column="id" property="id" jdbcType="INTEGER"/>
 6         <result column="name" property="name" jdbcType="VARCHAR"/>
 7         <result column="phone" property="phone" jdbcType="CHAR"/>
 8         <result column="telephone" property="telephone" jdbcType="VARCHAR"/>
 9         <result column="address" property="address" jdbcType="VARCHAR"/>
10         <result column="enabled" property="enabled" jdbcType="BIT"/>
11         <result column="username" property="username" jdbcType="VARCHAR"/>
12         <result column="password" property="password" jdbcType="VARCHAR"/>
13         <result column="userface" property="userface" jdbcType="VARCHAR"/>
14         <result column="remark" property="remark" jdbcType="VARCHAR"/>
15     </resultMap>
16     <select id="loadUserByUsername" resultMap="BaseResultMap">
17         select * from Hr where username=#{username}
18     </select>
19 </mapper>

六、创建配置类

 1 package org.yybb.securitylogin.config;
 2 
 3 import org.springframework.beans.factory.annotation.Autowired;
 4 import org.springframework.context.annotation.Bean;
 5 import org.springframework.context.annotation.Configuration;
 6 import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
 7 import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
 8 import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
 9 import org.springframework.security.crypto.password.PasswordEncoder;
10 import org.yybb.securitylogin.service.HrService;
11 
12 /**
13  * @Author: Ben
14  * @CreateTime: 2020-03-12 06:28
15  */
16 @Configuration
17 public class SecurityConfig extends WebSecurityConfigurerAdapter {
18 
19     @Autowired
20     HrService hrService;
21     @Bean
22     PasswordEncoder passwordEncoder() {
23         return new BCryptPasswordEncoder();
24     }
25 
26     @Override
27     protected void configure(AuthenticationManagerBuilder auth) throws Exception {
28         auth.userDetailsService(hrService);
29     }
30 
31 }

再测试就可以用数据库里面的用户进行登录啦.....

下面开始配置登录成功、失败、注销

  1 package org.yybb.securitylogin.config;
  2 
  3 import com.fasterxml.jackson.databind.ObjectMapper;

 10 import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
 11 import org.springframework.security.core.Authentication;
 12 import org.springframework.security.core.AuthenticationException;
 13 import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
 14 import org.springframework.security.crypto.password.PasswordEncoder;
 15 import org.springframework.security.web.authentication.AuthenticationFailureHandler;
 16 import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
 17 import org.springframework.security.web.authentication.logout.LogoutSuccessHandler;
 18 import org.yybb.securitylogin.model.Hr;
 19 import org.yybb.securitylogin.model.RespBean;
 20 import org.yybb.securitylogin.service.HrService;
 21 
 22 import javax.servlet.ServletException;
 23 import javax.servlet.http.HttpServletRequest;
 24 import javax.servlet.http.HttpServletResponse;
 25 import java.io.IOException;
 26 import java.io.PrintWriter;
 27

 32 @Configuration
 33 public class SecurityConfig extends WebSecurityConfigurerAdapter {
 34

 36     HrService hrService;
 37 
 38     @Bean
 39     PasswordEncoder passwordEncoder() {
 40         return new BCryptPasswordEncoder();
 41     }
 42 
 43     @Override

 69                         hr.setPassword(null);
 70                         RespBean success = RespBean.success("登录成功!", hr);

测试

测试是成功了，但是角色没有，下面把返回角色查询出来就行，大家应该注意到，我的实体类别Hr里面返回的角色是return null;

所以首先把它加在Hr

 1  /**
 2      * 返回用户角色
 3      * @return
 4      */
 5     @Override
 6     public Collection<? extends GrantedAuthority> getAuthorities() {
 7         List<SimpleGrantedAuthority>authorities=new ArrayList<>(roles.size());
 8         for (Role role : roles) {
 9             authorities.add(new SimpleGrantedAuthority(role.getName()));
10         }
11         return authorities;
12     }

登录成功之后在service中给用户设置角色

1 //设置用户角色 2 hr.setRoles(hrMapper.getHrRolesById(hr.getId()));

给mapper加上方法，给xml加上SQL

1  /**
2      * 根据用户ID查询他拥有的角色
3      * @param id
4      * @return
5      */
6     List<Role> getHrRolesById(Integer id);

1  <select id="getHrRolesById" resultType="org.yybb.securitylogin.model.Role"> 
2 SELECT r.* FROM role r ,hr_role hrr WHERE hrr.rid=r.id AND hrr.hrid=#{id} 
3 </select>

最终测试

以上就是用springsecurity实现用户登录返回对应角色的全过程。。

公告

一、创建hr(user)表、role(角色)表、hr_role(用户角色关联表)

二、先不急做其他的，可以先测试一下，下面我随便写了个controller【创建springboot工程时记得加上springsecurity依赖】

三、访问hello

四、创建实体类

五、创建service和mapper和mapper.xml[service必须实现userdetaillservice接口]

六、创建配置类

最终测试
