获取本地文件（文件夹）上传，无点击事件

//url,realPath必填参数
 1 public String updatebendi()throws Exception{
        ServletContext servletContext = ServletActionContext.getServletContext();
        //获取项目根目录路径
        //String realPath= servletContext.getRealPath("/")+"image/yyy/yuangong";
        String realPath= "D:/image/yyy/yuangong";
        System.out.println("路径：：：:"+realPath);
        System.out.println("file:::"+file);
        File mulu=new File(realPath);
        if(!mulu.exists()){
            mulu.mkdir();
        }
        String url="D:/logs";
        //获取url的文件或文件夹
        File file2 = new File(url);
        File local=new File(mulu,file2.getName());
        System.out.println("名字：：：:"+file2.getName());
        
        //将file2文件拷贝到local文件
　　　　　//File local = new File(mulu,fileFileName);
      //FileUtils.copyFile(file2, local);
        
        //将file2文件夹拷贝到local文件夹
        FileUtils.copyDirectory(file2, local);
        return SUCCESS;
    }

2.copy几类用法

    //结果是cxyapi和cxyapi1在同一目录  
    FileUtils.copyDirectory(new File("D:/cxyapi"), new File("D:/cxyapi1"));   
    //结果是将cxyapi拷贝到cxyapi2下  
    FileUtils.copyDirectoryToDirectory(new File("D:/cxyapi"), new File("D:/cxyapi2"));  
      
    //拷贝文件  
    FileUtils.copyFile(new File("d:/cxyapi.xml"), new File("d:/cxyapi.xml.bak"));  
    //拷贝文件到目录中  
    FileUtils.copyFileToDirectory(new File("d:/cxyapi.xml"), new File("d:/cxyapi"));  
    //拷贝url到文件  
    FileUtils.copyURLToFile(new URL("http://www.cxyapi.com/rss/cxyapi.xml"), new File("d:/cxyapi.xml"));
