当不在方法签名中时，Spring MockMVC注入mockHttpServletRequest

您可以添加一个

RequestPostProcessor

with()

mockMvc().perform(  fileUpload("/upload")  .file(FileFactory.stringContent("myFile"))  .with(new RequestPostProcessor() {     public MockHttpServletRequest postProcessRequest(MockHttpServletRequest request) {       request.setRemoteAddr("12345");        return request;    }}));

这样的事情应该起作用。
