struts 2 上传显示进度条

[尼坤神]

我重写了MultiFileParser。在struts.xml里面配置了

 protected List<FileItem> parseRequest(HttpServletRequest servletRequest, String saveDir) throws FileUploadException {
        DiskFileItemFactory fac = createDiskFileItemFactory(saveDir);
        ServletFileUpload upload = createServletFileUpload(fac);
        
        upload.setSizeMax(maxSize) ;
        upload.setProgressListener(new UploadListener(servletRequest.getSession())) ;
        
        
        return upload.parseRequest(createRequestContext(servletRequest));
    }

<bean type="org.apache.struts2.dispatcher.multipart.MultiPartRequest" name="myRequestParser"
        class="com.cwb.listener.MultiFileParser" scope="default" optional="true" />
  	<constant name="struts.multipart.handler" value="myRequestParser" />

上传就爆异常，如下，求高手给指点一下。

[尼坤神]

求人不如求己。。。 在覆写的MultiFileParser类里把setLocaleProvider这个方法删除就没事了

[chiangho]

我也遇到这个问题，纠结中.....

[尼坤神]

public class UploadListener implements ProgressListener {

	private HttpSession session=null;
	
	public UploadListener (HttpSession session){  
        this.session = session ;  
        FileUploadStatus status = new FileUploadStatus() ;
        session.setAttribute("currentUploadStatus", status);
    }
	
	/**
	 * 更新状态
	 * @param readedBytes 读取字节总数 
	 * @param totalBytes 数据总长度
	 * @param currentItem 当前正在被读取的field号 
	 */
	public void update(long readedBytes, long totalBytes, int currentItem) {
		System.out.println("update:"+readedBytes+";"+totalBytes+";"+currentItem);
		
		FileUploadStatus status = (FileUploadStatus) session.getAttribute("currentUploadStatus") ;
		status.setReadTotalSize(readedBytes) ;
		status.setUploadTotalSize(totalBytes) ;
		status.setCurrentUploadFileNum(currentItem) ;
		
	}

}

这个监听方法，就没有大神知道吗？？？求指导
