ACTION中：
public InputStream getTargetFile() throws Exception{
        return ServletActionContext.getServletContext().getResourceAsStream("upload\\"+getDownloadFileName());
    }
    public String getDownloadFileName(){
        
         String downFileName=ServletActionContext.getRequest().getParameter("name");
        try{
            downFileName=new String(downFileName.getBytes(),"ISO8859-1");
        }catch(UnsupportedEncodingException e){
            e.printStackTrace();
        }
        return downFileName;
    }
怎么name得到的参数是中文就有问题呢，，，拔出异常
