//url,realPath必填参数
 1 public String updatebendi()throws Exception{
 2         ServletContext servletContext = ServletActionContext.getServletContext();
 3         //获取项目根目录路径
 4         //String realPath= servletContext.getRealPath("/")+"image/yyy/yuangong";
 5         String realPath= "D:/image/yyy/yuangong";
 6         System.out.println("路径：：：:"+realPath);
 7         System.out.println("file:::"+file);
 8         File mulu=new File(realPath);
 9         if(!mulu.exists()){
10             mulu.mkdir();
11         }
12         String url="D:/logs";
13         //获取url的文件或文件夹
14         File file2 = new File(url);
15         File local=new File(mulu,file2.getName());
16         System.out.println("名字：：：:"+file2.getName());
17         
18         //将file2文件拷贝到local文件
　　　　　//File local = new File(mulu,fileFileName);
19       //FileUtils.copyFile(file2, local);
20         
21         //将file2文件夹拷贝到local文件夹
22         FileUtils.copyDirectory(file2, local);
23         return SUCCESS;
24     }

2.copy几类用法

 1     //结果是cxyapi和cxyapi1在同一目录  
 2     FileUtils.copyDirectory(new File("D:/cxyapi"), new File("D:/cxyapi1"));   
 3     //结果是将cxyapi拷贝到cxyapi2下  
 4     FileUtils.copyDirectoryToDirectory(new File("D:/cxyapi"), new File("D:/cxyapi2"));  
 5       
 6     //拷贝文件  
 7     FileUtils.copyFile(new File("d:/cxyapi.xml"), new File("d:/cxyapi.xml.bak"));  
 8     //拷贝文件到目录中  
 9     FileUtils.copyFileToDirectory(new File("d:/cxyapi.xml"), new File("d:/cxyapi"));  
10     //拷贝url到文件  
11     FileUtils.copyURLToFile(new URL("http://www.cxyapi.com/rss/cxyapi.xml"), new File("d:/cxyapi.xml"));
