使用方法：

@Componentpublic class TPPStrategy implements Strategy {    @Autowired    private TPPTask tppTask;        public TPPStrategy() {       //  beanName 不规范会导致获取失败，看工具类描述        tppTask = SpringUtils.getBean("TPPTask");    }     @Override    public void consumeTask() {        tppTask.consumeTask();    }}
