Spring Security设置用户信息

spring security默认情况下存在一个名为user的账号，对应的密码会在控制台输出

2022-02-26 22:35:32.825  INFO 10816 --- [           main] .s.s.UserDetailsServiceAutoConfiguration : 

Using generated security password: 5a709d3a-0c45-4ff7-a294-8a5a1e8b1c54

可以通过以下三种方法修改登录账号

配置文件

spring:
  security:
    user:
      name: test
      password: 123

通过配置类

package com.example.securitydemo3.config;

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.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;


@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();
        String password = bCryptPasswordEncoder.encode("123");
        auth.inMemoryAuthentication()
                .withUser("admin")
                .password(password)
                .roles("admin");
    }

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

自定义实现类

实现UserDetailsService接口

package com.example.securitydemo3.service.impl;

import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.example.securitydemo3.domain.User;
import com.example.securitydemo3.mapper.UserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.AuthorityUtils;
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.stereotype.Service;

import java.util.List;


@Service("userDetailsService")
public class MyUserDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private UserMapper userMapper;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        QueryWrapper userQueryWrapper = new QueryWrapper<>();
        userQueryWrapper.lambda().eq(User::getUsername, username);
        User user = userMapper.selectOne(userQueryWrapper);
        if (user == null) {
            throw new UsernameNotFoundException("用户不存在！");
        }

        List roles = AuthorityUtils.commaSeparatedStringToAuthorityList("admin");
        String password = new BCryptPasswordEncoder().encode(user.getPassword());
        return new org.springframework.security.core.userdetails.User(user.getUsername(), password, roles);
    }
}

配置启用自定实现类

package com.example.securitydemo3.config;

import org.springframework.beans.factory.annotation.Autowired;
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;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;


@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsService userDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.formLogin() // 自定义登录页面
                // 设置自定义登录页面地址
                .loginPage("/login.html")
                // 登录访问路径
                .loginProcessingUrl("/user/login")
                // 默认登录成功跳转路径
                .defaultSuccessUrl("/index").permitAll()
                .and()
                .authorizeRequests()
                // 设置拦截放行路径
                .antMatchers("/", "/hello", "/user/login").permitAll()
                .anyRequest().authenticated()
                .and()
                // 关闭csrf防护
                .csrf().disable();
    }

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