java如何模拟多端口异常

Question

我得到一个例外：

WARN  exceptions - Handler execution resulted in exception
org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is org.apache.commons.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed. Stream ended unexpectedly
    at org.springframework.web.multipart.commons.CommonsMultipartResolver.parseRequest(CommonsMultipartResolver.java:163)
    at org.springframework.web.multipart.commons.CommonsMultipartResolver.resolveMultipart(CommonsMultipartResolver.java:139)

在文件上传过程中，我不知道在我的应用程序中可以重复什么。你知道这方面的工具吗？或者你能给我一些建议吗

Answer 1

你检查过spring's unit test了吗

@Test(expected=MultipartException.class)
public void isMultipartRequest() throws Exception {
     MockHttpServletRequest request = new MockHttpServletRequest();
     resolver.resolveArgument(paramMultipartFile, new ModelAndViewContainer(), new ServletWebRequest(request), null);
     fail("Expected exception");
}
