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

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

</struts-config>
?
web.xml配置：
<?xml version="1.0" encoding="UTF-8"?>
<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。
