表現出來的異常程式碼如下：

分析原因是：
public interface TaskTypeConstant{
enum TaskType{
TEST_TRIGGER("TestTrigger2");
public String typeName;
TaskType(final String name){
this.typeName=name;
}
}
}
static { JOB_RUNNER_MAP.put("hello", new TestTriggerService()); //1 JOB_RUNNER_MAP.put(TaskType.TEST_TRIGGER.typeName, SpringContextHolder.getBean(TestTriggerService.class));//2 JOB_RUNNER_MAP.put(TaskTypeConstant.TaskType.EQUIPMENT_APP_DATA.typeName, SpringContextHolder.getBean(EquipmentAppDataService.class));//3 }
看上面程式碼 static 塊裡面的第三步出了問題
最終發現
因為 EquipmentAppDataService.class 沒有加@Service註解，不在bean容器。 SpringContextHolder.getBean方法執行導致異常，從而影響到該類不能正
