paymentSlipPushService为null 调不到服务方方法，小错误忽略 服务层必备注解serive已加，应该是定时任务导致的错误 apiPost直接访问就可以 但是系统内定时任务执行时bean为null

大佬来帮我已被折磨一天；昨天还行呢

用bean工厂拿，不要用注入的

5

定时任务代码贴一下

bean工厂试过了，拿不到 我能感受到是定时任务出了问题，估计没初始上下文 但是这个定时任务代码不是我写的 我他妈太难受了

7

new出来的线程，脱离了Spring的容器

目前是我手动点的立即执行，但是apipost就行

10

非常有道理，这个定时任务启动时就会显示 - 新线程: XXX开始执行

这块代码执行完后就回到对应的定时任务类了

12

启动的时候拿一下你的那个bean，先确认spring中有这个bean

13

take from spring container instead of new. :tieba_087:

14

这都已经自己newInstance()了，不是spring 容器里的bean了吧，自己的实例去拿spring 容器的bean拿不到正常的吧

15

最好能贴出来报错的上下文, 报错的位置代码和调用处的代码, 最好能打印出来整个调用栈.
看你发的截图, 是通过newInstance实例化的对象, 里面的Field当然是null

16

尝试一下下面的办法:

  1. 这个地方改成从ApplicationContext中取对象, 而不是反射
  2. 改成setter注入, 并在实例化对象后, 手动set paymentSlipService
17

换成这种方法就行了，但是service里的dao又成null了

18

第一种方式我试过了，不行

19

I think you need take it from spring container. not use new.

20

套娃了，难搞。
