标签:resttemplate文件上传 springmvc文件上传测试
在使用springmvc提供rest接口实现文件上传时,有时为了测试需要使用RestTemplate进行调用,那么在使用RestTemplate调用文件上传接口时有什么特别的地方呢?实际上只需要注意一点就行了,就是创建文件资源时需要使用org.springframework.core.io.FileSystemResource类,而不能直接使用java.io.File对象。
Controller中的rest接口代码如下:
@ResponseBody @RequestMapping(value = "/upload.do", method = RequestMethod.POST) public String upload(String fileName, MultipartFile jarFile) { // 下面是测试代码 System.out.println(fileName); String originalFilename = jarFile.getOriginalFilename(); System.out.println(originalFilename); try { String string = new String(jarFile.getBytes(), "UTF-8"); System.out.println(string); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } // TODO 处理文件内容... return "OK"; }
@Test public void testUpload() throws Exception { String url = "http://127.0.0.1:8080/test/upload.do"; String filePath = "C:\\Users\\MikanMu\\Desktop\\test.txt"; RestTemplate rest = new RestTemplate(); FileSystemResource resource = new FileSystemResource(new File(filePath)); MultiValueMap<String, Object> param = new LinkedMultiValueMap<>(); param.add("jarFile", resource); param.add("fileName", "test.txt"); String string = rest.postForObject(url, param, String.class); System.out.println(string); }
其中:
String string = rest.postForObject(url, param, String.class);可以换成:
HttpEntity<MultiValueMap<String, Object>> httpEntity = new HttpEntity<MultiValueMap<String,Object>>(param); ResponseEntity<String> responseEntity = rest.exchange(url, HttpMethod.POST, httpEntity, String.class); System.out.println(responseEntity.getBody());
