关于静态方法利用@Autowired注入的service类问题

//把Judge类实例化到spring容器中
@Component
public class Judge{
  //注入service的类
  @Autowired
  private ZhangStatusService zhangStatusService;
  private static Judge JudgeService;
  public Judge() {
    super();
    // TODO Auto-generated constructor stub
  }
  /* 被@PostConstruct修饰的方法会在服务器加载Servlet的时候运行，并且只会被服务器调用一次，
  类似于Servlet的inti()方法。被@PostConstruct修饰的方法会在构造函数之后，init()方法之前运行。*/
  @PostConstruct
  public void init() {
    System.out.println("实例化成功");
    JudgeService = this;
    JudgeService.zhangStatusService = this.zhangStatusService;
  }
  public static boolean compile(Integer id) throws Exception {
    //调用Service类的方法
    JudgeService.zhangStatusService.updateStatusJduge(id);
    }
  }
}
