springboot项目如何在工具类中用到service或者bean实体

@Component
public class ResultAddOrEditUtil {

    @Autowired
    ICarTaskRecordDetailsService iCarTaskRecordDetailsService;

    private static ResultAddOrEditUtil resultAddOrEditUtil1;

    @PostConstruct
    public void init() {
        resultAddOrEditUtil1 = this;
		resultAddOrEditUtil1.iCarTaskRecordDetailsService = this.iCarTaskRecordDetailsService;
    }
    
    //方法中使用service
     public boolean returnDataAddOrUpdate(){
          resultAddOrEditUtil1.iCarTaskRecordDetailsService.list();
     }
}

@Component
public class JedisUtil {
    @Autowired
    private User user;

    private static JedisUtil jedisUtil;
    @PostConstruct
    public void init(){
        jedisUtil=this;
        jedisUtil.user= this.user;
    }
}

总结：
①工具类要添加@Component注解
②定义工具类静态实体： private static JedisUtil jedisUtil
③定义初始化方法，并在方法上添加@PostConstruct注解
④使用：通过工具类的静态对象调用。例如： resultAddOrEditUtil1.iCarTaskRecordDetailsService.list()
