spring security 之 自定义用户登录初体验

项目环境及依赖参考上一篇文章

https://www.cnblogs.com/HanShisi/p/13273772.html

1 创建一个继承了 WebSecurityConfigurerAdapter 的类 覆盖configure(HttpSecurity http)

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
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 MyCloudSecurityConfig extends WebSecurityConfigurerAdapter {

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

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
           .formLogin()
           .and()
           .authorizeRequests()
           .anyRequest()
           .authenticated();
    }
}

　

2 实现 UserDetailsService 这里密码设置为123456

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.userdetails.User;
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.password.PasswordEncoder;
import org.springframework.stereotype.Component;

@Component
public class MyCloudUserDetailService implements UserDetailsService {

    private Logger logger = LoggerFactory.getLogger(MyCloudUserDetailService.class);

    @Autowired
    private PasswordEncoder passwordEncoder;

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

        logger.info(passwordEncoder.encode("123456"));
        return new User(username,passwordEncoder.encode("123456"),
                true,
                true,
                true,
                true,
                AuthorityUtils.commaSeparatedStringToAuthorityList("admin"));
    }
}

　　

重启项目  使用任意用户名和密码 123456 即可登录项目。

说明：MyCloudUserDetailsServiceImpl 在这个类中 可以注入各自项目中的dao层 查询用户信息将查询出的用户名和密码替换username 和 密码（123456）

 PS: spring 5.0以后密码的传参方式有变必须要给一个加密方式
