feign 接口返回流
@GetMapping("/{id}")
public void queryJobInfoLogDetail(@PathVariable("id") Long id, HttpServletResponse response) {
File file = new File("xxxxx");
InputStream fileInputStream = new FileInputStream(file);
OutputStream outStream;
try {
outStream = response.getOutputStream();
byte[] bytes = new byte[1024];
int len = 0;
while ((len = fileInputStream.read(bytes)) != -1) {
outStream.write(bytes, 0, len);
}
fileInputStream.close();
outStream.close();
outStream.flush();
} catch (IOException e) {
log.error("exception", e);
}
}
@GetMapping(value = "/{id}", consumes = MediaType.APPLICATION_JSON_UTF8_VALUE)
feign.Response queryJobInfoLogDetail(@PathVariable("id") Long id);
@GetMapping("/{id}")
public void queryJobInfoLogInfoList(@PathVariable("id") Long id, HttpServletResponse servletResponse) {
Response response = apiServices.queryJobInfoLogDetail(id);
Response.Body body = response.body();
InputStream fileInputStream = null;
OutputStream outStream;
try {
fileInputStream = body.asInputStream();
outStream = servletResponse.getOutputStream();
byte[] bytes = new byte[1024];
int len = 0;
while ((len = fileInputStream.read(bytes)) != -1) {
outStream.write(bytes, 0, len);
}
fileInputStream.close();
outStream.close();
outStream.flush();
} catch (Exception e) {
}
}
2.Could not resolve view with name xxx
问题：spring会认为你请求的结果是一个html的视图，所以才抛出了上面的异常。
解决方法：在请求的方法上加上@ResponseBody，或者有需要在控制层上加 @RestController 注解
3. 上传文件
服务调用者
@PostMapping("/xxx/file")
public xx uploadOrderFilesToOSS(@ApiParam("附件") @RequestParam("file") MultipartFile[] file) {
return xxxService.uploadOrderFilesToOSS(file);
}
Feign
@PostMapping(value = "/file", produces = {MediaType.APPLICATION_JSON_UTF8_VALUE}, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
xxx uploadSigleFile(@RequestParam("path") String path, @RequestPart("file") MultipartFile file);
服务提供者
@PostMapping(value = "/file", produces = {MediaType.APPLICATION_JSON_UTF8_VALUE}, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public xxx uploadSigleFile(@RequestParam("path") String path, @RequestPart("file") MultipartFile file) {
return fileService.uploadFileToOSS(path, file);
}
4. feign PathVariable获取文件后缀
今天在做一个返回图片接口，因鉴于通过get请求传参获取文件名和文件路径会出现严重漏洞问题，现采用直接以文件路径的方式访问文件下载，url这样的写法@RequestMapping(value = "/content/{fileName}", method = RequestMethod.GET)会导致文件类型丢失。
解决方案：
在@RequestMapping的value中使用SpEL来表示，value中的{fileName}换成{fileName:.+}。
@RequestMapping(value = "/content/{fileName:.+}", method = RequestMethod.GET)
比如我从图片服务器获取某一文件，路径是localhost:8080/file/test.jpg，
通过@PathVariable应该获取test.jpg，如果不做任何处理，结果获取到的是test。
解决方法：
@RequestMapping("/file/{filename:.+}")
