我已成功将图像文件上传到 WebContent\resources\uploads\image.jsp。但是我在使用 MockMvc 进行测试时遇到了问题。当我运行测试用例时，我得到了异常 file not found 和 access denied。

Controller 如下所示:

@RequestMapping(value="/AddContacts", method=RequestMethod.POST)
    public @ResponseBody String addContacts(ContactBean cb,HttpServletRequest request,HttpServletResponse response,@RequestParam("upload") MultipartFile file) throws IllegalStateException, IOException 
    {

        String error=cb.validate();
        if(error.equals("")){
            Model m=new Model();
            String ret=m.addData(cb);
            System.out.println("Contact Bean: "+cb);
            if(ret.equals("DBFAIL")){
                response.setStatus(500);
            }
            else if(ret.equals("EXIST")){
                response.setStatus(409);
            }
            else{
                response.setStatus(200);
                /* to upload a file */
                if(file != null && file.getSize() > 0){
                    System.out.println("File name: "+file.getOriginalFilename());
                    String dir="C:\\web_latest\\Admin_FileUpload_29_01_15\\WebContent\\resources\\uploads\\"+cb.getName()+"_"+cb.getId()+"\\";
                    //String dir="C:\\Upload\\"+cb.getName()+"_"+cb.getId()+"\\";
                    File directory = new File(dir);
                    if (directory.exists()) {
                        System.out.println("Directory already exists ...");

                    } 
                    else {
                        System.out.println("Directory not exists, creating now");
                        boolean success = directory.mkdir();
                        if (success) {
                            System.out.printf("Successfully created new directory : %s%n", dir);
                        } 
                        else {
                            System.out.printf("Failed to create new directory: %s%n", dir);
                        }
                    }
                    String fileName = file.getOriginalFilename();
                    file.transferTo(new File(dir+fileName));
                }
            }
            return error;
        }
        else{
            //response.setStatus(500);
            return error;
        }

    }

我的测试用例是这样的:

public void testAddContacts() throws Exception {
    FileInputStream fis=new FileInputStream("C:\\Users\\Public\\Pictures\\Sample Pictures\\Penguins.jpg");
    //MockMultipartFile upload = new MockMultipartFile("upload", "Penguins.jpg", "image/jpeg", "C:\\Users\\Public\\Pictures\\Sample Pictures\\Penguins.jpg\\".getBytes());

    MockMultipartFile upload= new MockMultipartFile("upload",fis);
    MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
      mockMvc.perform(MockMvcRequestBuilders.fileUpload("/AddContacts")
              .file(upload)
              .param("some-random", "4")
              .param("name","deerdad")
              .param("email","niharik@gmail.com")
              .param("phone", "1234567890"))
          .andExpect(status().is(200));
}

我的jsp文件是这样的:

最佳答案 

public void testAddContacts() throws Exception{
            File f = new File("C:\\Users\\Public\\Pictures\\Sample Pictures\\Penguins.jpg");
            System.out.println(f.isFile()+"  "+f.getName()+f.exists());
            FileInputStream fi1 = new FileInputStream(f);
            FileInputStream fi2 = new FileInputStream(new File("C:\\Users\\Public\\Pictures\\Sample Pictures\\Tulips.jpg"));
            MockMultipartFile fstmp = new MockMultipartFile("upload", f.getName(), "multipart/form-data",fi1);
            MockMultipartFile secmp = new MockMultipartFile("upload", "Tulips.jpg","multipart/form-data",fi2); 
            MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
            mockMvc.perform(MockMvcRequestBuilders.fileUpload("/AddContacts")                
                    .file(fstmp)
                    .file(secmp)
                    .param("name","abc").param("email","abc@gmail.com").param("phone", "1234567890"))               
                    .andExpect(status().isOk());
    }
