• 本文仅为个人学习spring security 的体会记录，如您恰巧刷到，且对您有帮助，荣幸之至。
• • 引入maven文件

本文仅为个人学习spring security 的体会记录，如您恰巧刷到，且对您有帮助，荣幸之至。

引入maven文件

由于我是基于activiti7 顺便学习了 security内容，所以这里引入的是 activiti相关内容：

<dependency>
		<groupId>org.activiti</groupId>
		<artifactId>activiti-spring-boot-starter</artifactId>
		<version>7.1.0.M4</version>
	</dependency>
	<dependency>
		<groupId>org.activiti.dependencies</groupId>
		<artifactId>activiti-dependencies</artifactId>
		<version>7.1.0.M4</version>
		<type>pom</type>
	</dependency>
           

如果您是只了解 security ，则只需引入security相关内容即可：

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-security</artifactId>
</dependency>
           

如果此时启动项目，并访问之前的网页，网页会出现security默认登录界面，如下：

security默认用户名为：user，password则为项目启动时候输出的内容（Note:每次启动会不一样）

创建user表

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(100) DEFAULT NULL,
  `password` varchar(100) DEFAULT NULL,
  `role` varchar(100) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8
           

如果需要测试数据，可执行以下sql:

INSERT INTO `act-demo`.`user` (username,password,`role`) VALUES 
('admin','$2a$10$odKAc3F4D/RoAvMOjFpslOO4S0B7XbZ9H.AdtbdR4z6NpukXcwTbi','ROLE_ACTIVITI_USER')
,('nancy','$2a$10$odKAc3F4D/RoAvMOjFpslOO4S0B7XbZ9H.AdtbdR4z6NpukXcwTbi','ROLE_ACTIVITI_USER')
;
           

创建UserBean实体类

import java.util.Arrays;
import java.util.Collection;
import java.util.stream.Collectors;
@Component
public class UserBean implements UserDetails {
    private long id;
    private String username;
    private String password;
    private String role;
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return Arrays.stream(role.split(","))
                .map(s -> new SimpleGrantedAuthority(s))
                .collect(Collectors.toList());
    }
    @Override
    public String getPassword() {
        return password;
    }
    @Override
    public String getUsername() {
        return username;
    }
    @Override
    public boolean isAccountNonExpired() {
        return true;
    }
    @Override
    public boolean isAccountNonLocked() {
        return true;
    }
    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }
    @Override
    public boolean isEnabled() {
        return true;
    }
}
           

UserBeanMapper

import com.example.actdemo.pojo.UserBean;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Component;

@Mapper
@Component
public interface UserBeanMapper {
    @Select("select * from user where username = #{username}")
    UserBean selectByUsername(@Param("username") String username);
}
           

MyUserDetailsService

import com.example.actdemo.mapper.UserBeanMapper;
import com.example.actdemo.pojo.UserBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;

@Component
public class MyUserDetailsService implements UserDetailsService {
    @Autowired
    UserBeanMapper mapper;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
  //注释内容可用于初始设置密码加密时使用
//        String password= passwordEncoder().encode("111");
//        System.out.println("password ========== > " + password);
//        return new User(username,password, AuthorityUtils.commaSeparatedStringToAuthorityList("ROLE_ACTIVITI_USER"));
        /**
         * 此处只做了数据库查询工作
         * 将UserDetalis 返回到 框架之后
         * 由框架 完成 安全比对工作
         */
        UserBean userBean = mapper.selectByUsername(username);
        if(userBean == null){
            throw new UsernameNotFoundException("数据库中无此用户");
        }
        return userBean;
    }
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}
           

HelloController

@RestController
public class HelloController{
    @RequestMapping(value = "hello",method = RequestMethod.GET)
    public String hello(){
        return new String("welcome to activity");
    }
}
           

基于以上代码，可实现采用数据库的数据登录
