spring - 对依赖于请求上下文的方法进行单元测试

Question

我正在为包含以下行的方法编写单元测试:

String sessionId = RequestContextHolder.currentRequestAttributes().getSessionId();

我收到以下错误:

java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

原因很明显——我没有在请求上下文中运行测试。

问题是，如何在测试环境中测试包含对依赖于请求上下文的方法的调用的方法？

非常感谢。

Spring-test 有一个灵活的请求模拟，称为 MockHttpServletRequest。

MockHttpServletRequest request = new MockHttpServletRequest();
RequestContextHolder.setRequestAttributes(new ServletRequestAttributes(request));
