jsp 页面 图片请求成功后 请求路径被当成jsp页面地址

Question

问题描述 图片请求成功，图片正常显示，但是后台报错误； 页面图片请求 <img src="/file/see/${item.image}" /> Request URL: http://127.0.0.1:8081/file/see/71 Request Method: GET Status Code: 200 OK Remote Address: 127.0.0.1:8081 Referrer Policy: no-referrer-when-downgrade Content-Disposition: inline;fileName=20180905185410754FFL.png Content-Type: image/png Date: Thu, 06 Sep 2018 02:54:41 GMT Server: Apache-Coyote/1.1 Transfer-Encoding: chunked Accept: image/webp,image/apng,image/*,*/*;q=0.8 Accept-Encoding: gzip, deflate, br Accept-Language: zh-CN,zh;q=0.9 Connection: keep-alive Cookie: sid=9bf5a6b7-36b7-46ae-8fdb-04ffc662986c; tset=test123; JSESSIONID=338F787EDC932735E50D98AC13B866EC Host: 127.0.0.1:8081 Referer: http://127.0.0.1:8081/ User-Agent: Mozilla/5.0 (Linux; Android 5.0; SM-G900P Build/LRX21T) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Mobile Safari/537.36 控制台报错信息 九月 06, 2018 10:27:03 上午 org.apache.catalina.core.ApplicationDispatcher invoke 严重: Servlet.service() for servlet jsp threw exception javax.servlet.ServletException: File &quot;/WEB-INF/jsp/file/see/71.jsp&quot; not found …… 问题出现的环境背景及自己尝试过哪些方法 一开始请求方法是由json返回值的，后来我把返回值去掉还是不行；网上搜索说可能是response重复调用问题？我推测可能是jsp页面把这个请求地址当成静态页面取获取了，结果就后台找不到页面所有报错了； 相关代码 // 请把代码文本粘贴到下方（请勿用图片代替代码）图片请求方法 @RequestMapping("/see/{id}") public void seeUrl(@PathVariable("id")Integer id) { sysFileService.fileDownload(id, false, true, response); } @Override public void fileDownload(Integer id, Boolean isName, Boolean isOpen, HttpServletResponse response) { TbFile tbFile = tbFileMapper.selectByPrimaryKey(id); if( null != tbFile) { File file = new File(tbFile.getSaveDir() + "/" + tbFile.getSaveName() + "." + tbFile.getFileSuffix()); if(file.exists()){ try { FileUtils.fileDownload(file, tbFile, response, isName, isOpen); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } } public static void fileDownload(File file, TbFile tbFile, HttpServletResponse response, Boolean isName, Boolean isOpen) throws FileNotFoundException, IOException { String fullName = ""; //是否使用生成的文件名 if(null == isName) { fullName = new String(tbFile.getFileName().getBytes(),"ISO-8859-1") + "."+tbFile.getFileSuffix(); } else { fullName = new String(tbFile.getSaveName().getBytes(),"ISO-8859-1") + "."+tbFile.getFileSuffix(); } //是否打开 if(null == isOpen) { //强制下载 response.setContentType("application/force-download"); response.setHeader("Content-Disposition", "attachment;fileName=" + fullName); }else { //浏览器查看 response.setContentType(tbFile.getFileType()); response.setHeader("Content-Disposition", "inline;fileName=" + fullName); } streamWrite(new FileInputStream(file), response.getOutputStream()); logger.info( "fileDownload---" + "\t文件名:" + tbFile.getFileName() + "\t文件后缀类型：" + tbFile.getFileType() + "\t文件大小：" + tbFile.getFileSize() + "\t生成文件目录：" + tbFile.getSaveDir() + "\t生成文件名：" + tbFile.getSaveName() ); } public static void streamWrite(InputStream is, OutputStream os) throws IOException { byte[] b = new byte[1024]; int len; while((len = is.read(b)) != -1) { os.write(b, 0, len); } os.flush(); os.close(); is.close(); } 你期待的结果是什么？实际看到的错误信息又是什么？ 1.这个请求路径还需要再配置不访问jsp文件吗2.还是后台response的时候给设置一个值返回成功后不再请求
