最近用spring MVC做一个文件下载程序的时候，发现IE对HttpStatus.CREATED状态的并非完全支持
如：
[java] view plain copy print?
@RequestMapping(value = "/download", method = RequestMethod.POST ) @ResponseBody public ResponseEntity<byte[]> download( @RequestParam("fileName") String fName) throws IOException { System.out.println(fName); String path = this.servletContext.getRealPath("/WEB-INF/load") + "\\aaa\\" + fName; System.out.println(path); HttpHeaders headers = new HttpHeaders(); headers.setContentType(MediaType.APPLICATION_OCTET_STREAM); headers.setContentDispositionFormData("attachment", new String(fName.getBytes("GBK"),"ISO8859-1")); File file = new File(path); if(file.exists()){ return new ResponseEntity<byte[]>(FileUtils.readFileToByteArray( file), headers,HttpStatus.CREATED); } headers.setContentDispositionFormData("attachment", "error.txt"); return new ResponseEntity<byte[]>("发送错误.".getBytes(), headers, HttpStatus.CREATED); }在IE中并不能下载，而在其他浏览器是可以下载的，但是下面的代码却可以

@RequestMapping(value = "/download", method = RequestMethod.POST ) @ResponseBody public ResponseEntity<byte[]> download( @RequestParam("fileName") String fName) throws IOException { System.out.println(fName); String path = this.servletContext.getRealPath("/WEB-INF/load") + "\\aaa\\" + fName; System.out.println(path); HttpHeaders headers = new HttpHeaders(); headers.setContentType(MediaType.APPLICATION_OCTET_STREAM); headers.setContentDispositionFormData("attachment", new String(fName.getBytes("GBK"),"ISO8859-1")); File file = new File(path); if(file.exists()){ return new ResponseEntity<byte[]>(FileUtils.readFileToByteArray( file), headers,HttpStatus.OK); } headers.setContentDispositionFormData("attachment", "error.txt"); return new ResponseEntity<byte[]>("发送错误.".getBytes(), headers, HttpStatus.OK); }
