# 一、PasswordEncoder #

在@Configuration注解的类下注入bean：

import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
    import org.springframework.security.crypto.password.PasswordEncoder;
        @Bean
        public PasswordEncoder passwordEncoder () {
            return new BCryptPasswordEncoder();
        }

# 二、自定义登录业务 #

新建MyUserDetailsService类实现`org.springframework.security.core.userdetails.UserDetailsService` 接口 ：

package com.xh.sercurity;
    
    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 MyUserDetailsService implements UserDetailsService {
    
        private Logger logger = LoggerFactory.getLogger(getClass());
    
        @Autowired
        private PasswordEncoder passwordEncoder;
    
        @Override
        public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
            // 根据用户名查找用户信息
            logger.info("login username is : " + username);
            // 权限  
            // 账号过期 -账户是否锁定-密码过期-账户是否可用 
            // passwordEncoder.encode("123456") 这是注册用的，这里写数据库读出的
            logger.info("数据库密码是: " + passwordEncoder.encode("123456"));
            // 用户名  密码(数据库查出来的,security自动与用户传入的对比)  权限
            // 用户名  密码  权限
            return new User(username, passwordEncoder.encode("123456"), 
                    true,true,true,true,
                    AuthorityUtils.commaSeparatedStringToAuthorityList("admin"));
        }
    
    }
