上传多文件比较简单，大概就是把文件名，文件，文件类型等等保存成数组类型。然后再遍历数组进行保存就行了。

前台代码如下：

后台的处理代码如下：

package com.levi.action;
    
    import java.io.File;
    import java.util.Map;
    
    import org.apache.commons.fileupload.UploadContext;
    import org.apache.commons.io.FileUtils;
    
    import com.opensymphony.xwork2.ActionContext;
    import com.opensymphony.xwork2.ActionSupport;
    
    public class FileUploads extends ActionSupport
    {
    
    	/**
    	 * 
    	 */
    	private static final long serialVersionUID = 1L;
    	
    	private File[] fileUpload;
    	private String[] fileUploadFileName;
    	public File[] getFileUpload()
    	{
    		return fileUpload;
    	}
    
    	public void setFileUpload(File[] fileUpload)
    	{
    		this.fileUpload = fileUpload;
    	}
    
    	public String[] getFileUploadFileName()
    	{
    		return fileUploadFileName;
    	}
    
    	public void setFileUploadFileName(String[] fileUploadFileName)
    	{
    		this.fileUploadFileName = fileUploadFileName;
    	}
    
    	public String[] getFileUploadContentType()
    	{
    		return fileUploadContentType;
    	}
    
    	public void setFileUploadContentType(String[] fileUploadContentType)
    	{
    		this.fileUploadContentType = fileUploadContentType;
    	}
    
    	private String[] fileUploadContentType;
    	@Override
    	public String execute() throws Exception
    	{
    		ActionContext actionContext=ActionContext.getContext();
    		Map<String, Object> session=actionContext.getSession();
    		for(int i=0;i<fileUpload.length;i++)
    		{
    			String fileName="文件"+(i+1)+"的名字为:"+fileUploadFileName[i];
    			String fileContentType="文件"+(i+1)+"的类型为:"+fileUploadContentType[i];
    			System.out.println(fileName);
    			System.out.println(fileContentType);
    			String saveFilePath="d:\\upload\\"+fileUploadFileName[i];
    			File saveFile=new File(saveFilePath);
    			FileUtils.copyFile(fileUpload[i], saveFile);
    			session.put("fileUploadFileName", fileUploadFileName);//这里是保存到session中，以便后面获取使用
    			session.put("fileUploadContentType", fileUploadContentType);
    		}
    		return SUCCESS;
    	}
    }
