查询数据库用户信息的服务

@Service
public class UserService {

    /**
    * @Description: 这里应该写的是调用Dao层，根据主键查询出用户，由于我没有配置直接返回用户，注意，密码是经过加密的
    * @author: YunZhao.Wang
    * @date: 2020/10/21 10:26
    * @version:
    */

    public User getUser(String name){

       User user =  new User("1","test", new BCryptPasswordEncoder().encode("123")) ;
       if (user.getName().equals(name)){
           return user;
       }else {
           return new User();
       }
    }
}

实现security底层查询用户信息的接口，让security的底层查询数据的用户信息

@Service
public class CustomUserService implements UserDetailsService {

    @Autowired
    private UserService userService;

    @Override
    public UserDetails loadUserByUsername(String account) throws UsernameNotFoundException {
        //账号信息
        com.example.security.model.User accountInfo = userService.getUser(account);
        if (accountInfo == null)
            throw new UsernameNotFoundException("Account[" + account + "]not found");

        List<SimpleGrantedAuthority> authorities = new ArrayList<>();
        //对应的权限添加
        authorities.add(new SimpleGrantedAuthority("ROLE_USER"));

        return new User(accountInfo.getName(), accountInfo.getPassword(), authorities);

    }
}
