我想知道，我做的是否正确。因为DocMgmtService服务是一个接口，它没有实现。控制器调用后，按上述配置转到Transformer。在这个设置中，我有以下问题

我可以用相同的设置模拟DocMgmtService吗？如果不是，正确的方法是什么

如果是的话，我怎么能嘲笑我的服务呢。谢谢

这完全取决于你想要测试什么

如果您模拟接口，那么您要测试的就是该接口的模拟存根（无意义）

框架创建接口的一个实现，该接口从参数创建消息并将其发送到通道

您应该将网关自动连接到测试中并调用它

您可以根据需要模拟任何下游组件（例如，

sendComnMsgActivator

）。

谢谢您的回复。是的，你的回答是正确的，我必须自动连接网关。但我已经试过了，结果是无效的。您能建议如何使用现有设置@Autowired网关吗？谢谢，我得到了它，而不是PowerMockito，我使用SpringJUnit4ClassRunner，仅此而已；我的电话是来变压器。再次感谢你救了我。
