import org.springframework.http.HttpHeaders; import org.springframework.http.HttpStatus; import org.springframework.http.MediaType; import org.springframework.http.ResponseEntity; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class MyController { @RequestMapping("download.do") public ResponseEntity byte[] download() throws IOException { File file=new File("F://Y2//OA//.metadata//.me_tcat//webapps//SpringMVC_fileupload//images//111.jpg"); HttpHeaders headers = new HttpHeaders(); String fileName=new String("你好.jpg".getBytes("utf-8"),"iso-8859-1");//为了解决中文名称乱码问题 headers.setContentDispositionFormData("attachment", fileName); headers.setContentType(MediaType.APPLICATION_OCTET_STREAM); return new ResponseEntity byte[] (FileUtils.readFileToByteArray(file), headers, HttpStatus.CREATED); }
