编写action类

package hu.action;

import java.io.File;
import java.io.IOException;

import org.apache.commons.io.FileUtils;
import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

public class FileAction extends ActionSupport {
   private File[] upload;
   private String[] uploadFileName;
   private String[] uploadContextType;

   private String path;
   public String saveFile() {
       // TODO Auto-generated method stub
       path = ServletActionContext.getServletContext().getRealPath("upload");

       try {
       for (int i = 0; i < upload.length; i++) {

           FileUtils.copyFile(upload[i], new File(path+"/"+uploadFileName[i]));
       }

           System.out.println("ad");
       } catch (IOException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }

           return SUCCESS;


   }
   public File[] getUpload() {
       return upload;
   }
   public void setUpload(File[] upload) {
       this.upload = upload;
   }
   public String[] getUploadFileName() {
       return uploadFileName;
   }
   public void setUploadFileName(String[] uploadFileName) {
       this.uploadFileName = uploadFileName;
   }
   public String[] getUploadContextType() {
       return uploadContextType;
   }
   public void setUploadContextType(String[] uploadContextType) {
       this.uploadContextType = uploadContextType;
   }
   public String getPath() {
       return path;
   }
   public void setPath(String path) {
       this.path = path;
   }



}

添加action的配置文件

<package name="action" extends="struts-default" namespace="/action">

       <action name="*_B1ction" class="hu.action.FileAction" method="{1}">
           <result name="success">/filesuccess.jsp</result>
           <result name="input">/error.jsp</result>
           <interceptor-ref name="fileUpload">

               <param name="allowedTypes">image/jpeg,image/bmp,image/gif</param>

           

               <param name="maximumSize ">10000</param>

           </interceptor-ref>
           <interceptor-ref name="defaultStack" />
       </action>
