Mock RequestContextListener

用Mock模拟

MockHttpServletRequest request = new MockHttpServletRequest(context);

遇到下面错误时：

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.

 

可以参考springframework里面的tester的写法
