我已经阅读了一些有关集成测试的教程。他们建议使用TestRestTemplate发出请求。但是，当我这样做

restTemplate.postForObject()

它不尊重@WithMockUser我不认为，我遇到了

这样的异常 
org.springframework.web.client.ResourceAccessException: I/O error on POST request for "http://localhost:60196/api/v1/users": cannot retry due to server authentication, in streaming mode; nested exception is java.net.HttpRetryException: cannot retry due to server authentication, in streaming mode

但是，在我的单元测试中，当我通过

发出HTTP请求时 
mockMvc.perform(request)

@WithMockUser确实可以工作，并且无需传递JWT令牌。

那是为什么？

1 个答案:

答案 0 :(得分：0)

由@WithMockUser管理的模拟用户基于线程，并且MockMvc和TestRestTemplate具有不同的线程模型。

当您使用MockMvc时，将模拟HTTP层和servlet容器，并且将来自测试的调用直接在同一线程上直接发送到Spring MVC的调度程序servlet中。在这种情况下，可以使用模拟用户。

使用TestRestTemplate时，您正在发出完整的HTTP请求。该请求在测试运行所在的线程上发送，并由服务器上的其他线程处理。在这种情况下，模拟用户在处理请求的线程上不可用，因为它与配置模拟用户并发出请求的线程不同。
