Spring MockMVC inject mockHttpServletRequest when not in method signature
You can add a RequestPostProcessor. Which you can then pass in to the mockmvc stuff by using the with() method.
mockMvc().perform( fileUpload("/upload") .file(FileFactory.stringContent("myFile")) .with(new RequestPostProcessor() { public MockHttpServletRequest postProcessRequest(MockHttpServletRequest request) { request.setRemoteAddr("12345"); return request; }}));Something like that should work.
