线程中调用service方法出错

public class PnFileTGIComputeThread implements Runnable {
    @Resource
    private AppUsedService   appUsedService;
//    AppUsedService appUsedService = (AppUsedService) AllBean.getBean("appUsedService");
    public  String taskId;
    public  int  cityId;
    public PnFileTGIComputeThread(String name, int cityId){
        this.taskId = name;
        this.cityId = cityId;
    }
    @Override
    public void run() {
        try {
            this.appUsedService.doSaveAzTaskAppUsedInfoCity(Integer.valueOf(taskId),cityId);
        } catch (Exception e){
           e.printStackTrace();
        }
    }
}

老办法，翻了度娘的牌子，找到问题，在线程中为了线程安全，是防注入。没办法，要用到这个类啊。只能从bean工厂里拿个实例了

public class AllBean implements ApplicationContextAware{
   
    private static ApplicationContext applicationContext; 
   
    public void setApplicationContext(ApplicationContext context) {
       AllBean.applicationContext = context;
       }
   
    public static Object getBean(String name){
         return applicationContext.getBean(name);
    }
    
     public static ApplicationContext getApplicationContext() {  
          return applicationContext;  
      }  
}

<bean id="allBean" class="xxxxx.AllBean"  />

AppUsedService appUsedService = (AppUsedService) AllBean.getBean("appUsedService");
