struts1上传多个文件

html：

注意：<form action="*"  mothed="post" enctype="multipart/form-data">的设置

action类：

package test;

import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Hashtable;
import java.util.Iterator;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.upload.FormFile;

public class UploadFileSampAction extends Action {

 public ActionForward execute(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {

  // 获得上传的文件信息
  Hashtable fileh = form.getMultipartRequestHandler().getFileElements();
  String dirPath = getServlet().getServletContext().getRealPath("/")
    + "upload";

  if (fileh != null) {
   // 如果目录不存在，则创建
   File fpath = new File(dirPath);
   if (!fpath.exists()) {
    fpath.mkdir();
   }
   // 解析上传文件
   for (Iterator it = fileh.keySet().iterator(); it.hasNext();) {
    String key = (String) it.next();
    try {
     FormFile formfile = (FormFile) fileh.get(key);
     String filename = formfile.getFileName().trim(); // 文件名
     if (!"".equals(filename)) {

      InputStream ins = formfile.getInputStream();
      OutputStream os = new FileOutputStream(dirPath
        + File.separatorChar + filename);
      System.out.println("=======file dirPath========="
        + dirPath);
      System.out.println("=======file separatorChar========="
        + File.separatorChar);
      System.out.println("=======file filename========="
        + filename);
      int bytesRead = 0;
      byte[] buffer = new byte[8192];
      while ((bytesRead = ins.read(buffer, 0, 8192)) != -1) {
       os.write(buffer, 0, bytesRead);
      }
      os.close();
      ins.close();

     }
    } catch (Exception ex) {
     ex.printStackTrace();
    }
   }
  }

  return mapping.findForward("success");
 }
}

struts-config.xml配置：

<?xml version="1.0" encoding="gb2312" ?>
<!DOCTYPE struts-config PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
          "http://struts.apache.org/dtds/struts-config_1_2.dtd">

<struts-config>
 <form-beans>
   <form-bean type="test.UploadFileSample"/>
 </form-beans>
 
  <action-mappings>

  <action    path="/uploadfile"
       type="test.UploadFileSampAction"
      
       scope="request">
   <forward     path="/test.html"/>
  </action>

  </action-mappings>

</struts-config>

 

web.xml配置：

<?xml version="1.0" encoding="UTF-8"?>
<web-app>
   
    <servlet>
        <servlet-name>action</servlet-name>
        <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
         <init-param>
         <param-name>config</param-name>
         <param-value>
     /WEB-INF/struts-config.xml
    </param-value>
      </init-param>
     <load-on-startup>2</load-on-startup>
    </servlet>

 <servlet-mapping>
     <servlet-name>action</servlet-name>
     <url-pattern>*.do</url-pattern>
 </servlet-mapping>

</web-app>

以上是主要的代码以及配置，最后需要部署到应用服务器上运行试试！！祝大家好运。
