spring mvc模式下 下载xml格式的文档相关代码：

@RequestMapping(value = "/shili")
    public ResponseEntity<byte[]>  load(HttpServletRequest request)throws IOException {
       
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_XML);
        headers.setContentDispositionFormData("attachment", riskcode+".xml");
        StringBuffer a =request.getRequestURL();
        String rootPath = request.getContextPath();
        return new ResponseEntity<byte[]>(FileUtils.readFileToByteArray(new File("")),
                headers, HttpStatus.CREATED);
//      
    }

struts 配置中下载xml格式文档主要配置

<action name="shili" class="downAction" method="shili">
 <result type="stream" name="success">
 <!-- 文件MIME类型 -->
 <!-- ${contentType}读取Action的getContentType方法 -->
 <param name="contentType">${contentType}</param>
 <!-- 下载附件名称contentDisposition 格式：attachment;filename=xxxx -->
 <param name="contentDisposition">attachment;fileName=${
 file}</param>
 <!-- 设置流方法名称,必须Action内部 提供 getTarget 返回值InputStream， 用来返回文件内容 -->
 <param name="inputName">target</param>
 </result>
 <!-- 用户下载权限校验 -->
 </action>
