javax.servlet.ServletException:?ClientAbortException:??java.net.SocketException:?Broken?pipe錯誤完美解決

現在百度太垃圾了，啥都搜不出來，啥時候才能上google,簡直成一個夢想了

?

用chrome跟蹤發現下載文件時出現如下錯誤：

錯誤 349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION)：我們收到了多個“Content-Disposition”標頭。我們不允許此行為，以防遭到 HTTP 響應拆分攻擊。

?

原代碼為:

public String downloadFile() throws Exception {
??HttpServletResponse response = ServletActionContext.getResponse();
??HttpSession session = HttpRequester.getHttpSession();
??Object su = session.getAttribute("ACCOUNT");
??if (su == null) {
???System.out.println("session超時");
???throw new Exception("session超時");
??}
??taskResultExcel = downloadFile.substring(downloadFile.lastIndexOf("/")+1, downloadFile.length());
??response.setContentType("application/vnd.ms-excel");
??response.setHeader("Content-Disposition", "attachment;filename=\""+ taskResultExcel + "\"");
??response.setHeader("Cache-Control","must-revalidate, post-check=0, pre-check=0");
??response.setHeader("Pragma", "public");
??return SUCCESS;
?}

修改為如下代碼即可解決

Caused by: ClientAbortException:? java.net.SocketException: Broken pipe

public String download() {
??HttpServletResponse response = getResponse();
??String flag = SUCCESS;
??log.info("下載的文件為: " + downloadFile);
??????? try {
??????????? String filePath2 = ServletActionContext.getServletContext().getRealPath("/"); //取當前系統路徑
??????????? // path是指欲下載的文件的路徑。在path 路徑下創建名為

??????????? // 取得文件名。
??????????? String filename = file.getName();
??????????? // 取得文件的后綴名。
