spring Boot 用@Autowired自动注入UserDetailsService 找不到bean

Question

package com.hrbust.server.service.impl;

import com.hrbust.server.config.security.JwtTokenUtil;
import com.hrbust.server.pojo.Admin;
import com.hrbust.server.mapper.AdminMapper;
import com.hrbust.server.pojo.RespBean;
import com.hrbust.server.service.IAdminService;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Service;

import javax.servlet.http.HttpServletRequest;
import java.util.HashMap;
import java.util.Map;

  @Service
  public class AdminServiceImpl extends ServiceImpl<AdminMapper, Admin> implements IAdminService {

  @Autowired
  private UserDetailsService userDetailsService;
  @Autowired
  private PasswordEncoder passwordEncoder;
  @Autowired
  private JwtTokenUtil jwtTokenUtil;
  @Value("${jwt.tokenHead}")
  private String tokenHead;

  @Override
  public RespBean login(String username, String password, HttpServletRequest request) {

    //登录
    UserDetails userDetails = userDetailsService.loadUserByUsername(username);
    if(userDetails == null || !passwordEncoder.matches(password,userDetails.getPassword())){
        return RespBean.error("用户名或密码不正确");
    }
    if(!userDetails.isEnabled()){
        return RespBean.error("账号被禁用，请联系管理员！");
    }
    return null;
  

  }

这是今天做乐字节的云E办开源项目时候遇到的问题，@Autowired就说找不到相关的bean，其他的pojo等等层都是逆向工程数据库直接自动生成的，没找到问题。上网找解决方案说让重启清缓存都试过了还是没有用。
