测试一个spring文件上传表单，controlelr签名是这样的
@RequestMapping(value = "upload", method = RequestMethod.POST)
@ResponseBody
public void upload(@RequestParam("file") MultipartFile multipartFile) {}
和测试这个
final MockMultipartFile file
= new MockMultipartFile("content", "myFile.txt", "text/plain", "hello".getBytes());
MockHttpServletRequestBuilder mockHttpServletRequestBuilder =
.fileUpload("/upload/")
.file(file)
.accept(MediaType.APPLICATION_JSON);
但我得到了前面提到的:错误消息 = 所需的 MultipartFile 参数"file"不存在
最佳答案
您将参数命名为"file"而不是“内容”:
改变:
new MockMultipartFile("content", "myFile.txt", "text/plain", "hello".getBytes());
至:
new MockMultipartFile("file", "myFile.txt", "text/plain", "hello".getBytes());
