How to purposely get a 409 HTTP Conflict response from a server?
问题
我们正在使用Spring Retry实现针对HTTP 409冲突响应的重试机制，有时我们在生产服务器上会收到这种响应。
但我们想知道如何有意地让服务器以409状态代码响应？在我们的情况下，错误似乎每当我们尝试并行加载大量数据时都会发生；由于发生的概率似乎相当随机，是否有一种方法可以在测试目的下获得一致的结果？
英文:
We are implementing a retry mechanism (using Spring Retry) for http 409 Conflict responses, which we sometimes get on the production server.
But we wonder how to purposely get a server to respond with a 409 status code? In our cases, the error seems to happen whenever we try to load a lot of data in parallel; since the probability of it happening seems quite random, is there a method to get it consistently for testing purposes?

这是要翻译的内容：
"好吧，可能有多种可能的方法来实现这个，您需要澄清您希望在哪里引发409错误，
我假设（这是Spring Boot应用程序）您的一个服务（A）调用另一个服务/API（B），您希望它引发409错误。
如果是这种情况，您可以编写**@RunWith(SpringRunner.class)/@SpringBootTest**测试，并模拟来自服务/API B的409响应，然后测试您的重试机制。"
英文:
Well, There might be multiple possible ways to do so, You need to clarify where exactly you need 409 to be thrown ,
I assume (Its spring boot app) from one of your service (A) calls to another service/API(B) and you expect it to throw 409.
If that's the case, you can write @RunWith(SpringRunner.class)/@SpringBootTest test and mock the response from service/API B with 409 and test your retry mechanism.
