SpringSecurity 认证快速入门

1、导入依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.example</groupId>
    <artifactId>myspringsecurity</artifactId>
    <version>1.0-SNAPSHOT</version>

    <parent>
        <artifactId>spring-boot-starter-parent</artifactId>
        <groupId>org.springframework.boot</groupId>
        <version>2.5.0</version>
    </parent>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <scope>test</scope>
        </dependency>

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

        <dependency>
            <groupId>com.mysql</groupId>
            <artifactId>mysql-connector-j</artifactId>
            <version>8.0.33</version>
        </dependency>

        <dependency>
            <groupId>com.baomidou</groupId>

        <dependency>

            <artifactId>fastjson</artifactId>
            <version>2.0.7</version>
        </dependency>

        <dependency>
            <groupId>org.projectlombok</groupId>

        </dependency>

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


</project>

2、配置application.properties

server.port=8002

spring.application.name=spring-security

spring.datasource.url=jdbc:mysql://localhost:3306/mybatis-plus?characterEncoding=utf-8&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=12345
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

3、编写domain，SecurityUser，User；

package com.wen.security.domain;

import lombok.Data;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;

import java.util.Collection;

/**
 * @author 文杰
 * @version 1.0
 */

@Data
public class SecurityUser implements UserDetails {

    private User user;

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return null;
    }

    @Override
    public String getPassword() {
        return null;
    }

    @Override
    public String getUsername() {
        return null;
    }

    @Override
    public boolean isAccountNonExpired() {
        return false;
    }

    @Override
    public boolean isAccountNonLocked() {
        return false;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return false;
    }

    @Override
    public boolean isEnabled() {
        return false;
    }
}

package com.wen.security.domain;

import lombok.Data;

import java.util.Date;

/**
 * @author 文杰
 * @version 1.0
 */

@Data
public class User {

    /**
     * 主键
     */
    private Long id;
    /**
     * 用户名
     */
    private String userName;
    /**
     * 昵称
     */
    private String nickName;
    /**
     * 密码
     */
    private String password;
    /**
     * 账号状态（0正常 1停用）
     */
    private String status;
    /**
     * 邮箱
     */
    private String email;
    /**
     * 手机号
     */
    private String phonenumber;
    /**
     * 用户性别（0男，1女，2未知）
     */
    private String sex;
    /**
     * 头像
     */
    private String avatar;
    /**
     * 用户类型（0管理员，1普通用户）
     */
    private String userType;
    /**
     * 创建人的用户id
     */
    private Long createBy;
    /**
     * 创建时间
     */
    private Date createTime;
    /**
     * 更新人
     */
    private Long updateBy;
    /**
     * 更新时间
     */
    private Date updateTime;
    /**
     * 删除标志（0代表未删除，1代表已删除）
     */
    private Integer delFlag;
}

4、编写UserMapper

package com.wen.security.mapper;


import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.wen.security.domain.User;

public interface UserMapper extends BaseMapper<User> {
}

5、编写UserDetailsServiceImpl

package com.wen.security.service.impl;

import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.wen.security.domain.SecurityUser;
import com.wen.security.domain.User;
import com.wen.security.mapper.UserMapper;
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 javax.annotation.Resource;
import java.util.List;

/**
 * @author 文杰
 * @version 1.0
 */

@Service
public class UserDetailServiceImpl implements UserDetailsService {

    @Resource
    UserMapper userMapper;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {

        User user = userMapper.selectOne(new LambdaQueryWrapper<User>().eq(User::getUserName, username));

        SecurityUser securityUser = new SecurityUser();
        securityUser.setUser(user);
        return securityUser;
    }

}

6、PasswordEncoder 替换

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}
