如何使用MockMvc爲DefaultMultipartHttpServletRequest控制器方法編寫單元測試？

Question

這樣的代碼：

@RequestMapping(value = "/upload/{resource}",method=RequestMethod.POST) 
@ResponseBody 
public Object uploadfileUpload(@PathVariable("resource") String resource,DefaultMultipartHttpServletRequest request,HttpServletResponse resp,MultipartFile file) throws IOException { 
    ...... 
} 

代碼

：

this.mockMvc.perform(mockMultipartHttpServletRequestBuilder) 

只能發佈MultipartHttpServletRequest，因爲mockMultipartHttpServletRequestBuilder implements MultipartHttpServletRequest。 MultipartHttpServletRequest是一個界面。

如何創建DefaultMultipartHttpServletRequest類對象然後在mockMvc發佈請求以完成我的單元測試？

Answer 1

@Test 
public void testUploadARA3() throws Exception { 
    FileInputStream file = new FileInputStream(
      "C:/test_42873.xlsm"); 
    MockMultipartFile multipartFile = new MockMultipartFile(
      "test_42873.xlsm", file); 
    MockMultipartHttpServletRequestBuilder mockMultipartHttpServletRequestBuilder = (MockMultipartHttpServletRequestBuilder) fileUpload(
      "/upload/{resource}", "ARA").accept(MediaType.ALL); 
    mockMultipartHttpServletRequestBuilder.file(multipartFile); 
    //mockMultipartHttpServletRequestBuilder.content("whatever"); 

    MockHttpServletRequest request; 
    MvcResult response = this.mockMvc.perform(mockMultipartHttpServletRequestBuilder).andDo(print()) 
      .andExpect(status().isOk()).andReturn(); 
    System.out.println(response.getResponse().getContentAsString()); 

} 

我的測試代碼沒有輸入uploadfileUpload方法。
