SpringBoot中使用RestTemplate发送文件流，以及读取zip压缩包中文件的方法

接收方与发送方代码

@RestController @RequestMapping("/optimistic") public class OptimisticController {     @Resource     private RestTemplate restTemplate;      //接收方     @PostMapping("receive")     public String receive(@RequestParam(value = "file",required = false) MultipartFile uploadFile) {         String originalFilename = uploadFile.getOriginalFilename();           return originalFilename;     }     //发送方     @PostMapping("send")     public String send(@RequestParam(value = "file",required = false) MultipartFile uploadFile) throws IOException {        //设置content-type为 multipart/form-data         HttpHeaders headers = new HttpHeaders();         headers.setContentType(MediaType.MULTIPART_FORM_DATA);         //获取流文件         InputStream inputStream = uploadFile.getInputStream();         InputStreamResource fileResource = new InputStreamResource(inputStream) {             //重写设置文件大小与名称             @Override             public long contentLength() {                 return uploadFile.getSize();             }              @Override             public String getFilename() {                 return uploadFile.getOriginalFilename();             }         };         MultiValueMap<String, Object> param = new LinkedMultiValueMap<>();         param.add("file",fileResource);         HttpEntity<MultiValueMap<String, Object>> requestEntity = new HttpEntity<>(param, headers);         String body = restTemplate.exchange("http://127.0.0.1:8088/optimistic/receive", HttpMethod.POST, requestEntity, String.class).getBody();         return body;     } }  

请求发送方接口成功返回

 读取zip压缩包中的文件方法

创建main函数测试

    public static void main(String[] args) throws IOException {         BufferedInputStream bufferedInputStream = new BufferedInputStream(new FileInputStream("D://jobhandler/zip/test.zip"));         ZipInputStream zis  = new ZipInputStream(bufferedInputStream);         ZipEntry zipEntry;         BufferedReader br = new BufferedReader(                 new InputStreamReader(zis));         while ((zipEntry = zis.getNextEntry()) != null) {             // 解压压缩文件的其中具体的一个zipEntry对象             String name = zipEntry.getName();             try {                 StringBuffer sb = new StringBuffer();                 String line;                 while ((line = br.readLine()) != null) {                     sb.append(line);                     sb.append("\r\n");                 }                  System.out.println(sb);              } catch (Exception e) {                 e.printStackTrace();             }             zis.closeEntry();         }         zis.close();         br.close();      }

成功读取zip中的json文件
