Struts Myeclipse Apache Java JSP

先看JSP

<%@ page language="java" pageEncoding="GBK"%>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>
<%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %>
<html:html lang="true">
  <head>
    <title>Upload.jsp</title>
  </head>
  
  <body>
    <html:form action="upload.do" method="post" enctype="multipart/form-data">
    	文件的名称：<html:text property="name"></html:text><br>
    	选择上传的文件：<html:file property="pic"></html:file><br>
    	<html:submit value="上传"/>
    </html:form>
  </body>
</html:html>

在看form

/*
 * Generated by MyEclipse Struts
 * Template path: templates/java/JavaClass.vtl
 */
package com.hcwy.struts.form;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.upload.FormFile;

/** 
 * MyEclipse Struts
 * Creation date: 06-06-2007
 * 
 * XDoclet definition:
 * @struts.form name="uploadForm"
 */
public class UploadForm extends ActionForm {
	/*
	 * Generated Methods
	 */
	private FormFile pic ;
	private String name ;
	/** 
	 * Method validate
	 * @param mapping
	 * @param request
	 * @return ActionErrors
	 */
	public ActionErrors validate(ActionMapping mapping,
			HttpServletRequest request) {
		// TODO Auto-generated method stub
		return null;
	}

	/** 
	 * Method reset
	 * @param mapping
	 * @param request
	 */
	public void reset(ActionMapping mapping, HttpServletRequest request) {
		// TODO Auto-generated method stub
	}

	public FormFile getPic() {
		return pic;
	}

	public void setPic(FormFile pic) {
		this.pic = pic;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
}

最后看action

/*
 * Generated by MyEclipse Struts
 * Template path: templates/java/JavaClass.vtl
 */
package com.hcwy.struts.action;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;

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 com.hcwy.struts.form.UploadForm;

/** 
 * MyEclipse Struts
 * Creation date: 04-08-2008
 * 
 * XDoclet definition:
 * @struts.action path="/upload" name="uploadForm" input="/form/upload.jsp" scope="request" validate="true"
 */
public class UploadAction extends Action {
	/*
	 * Generated Methods
	 */

	/** 
	 * Method execute
	 * @param mapping
	 * @param form
	 * @param request
	 * @param response
	 * @return ActionForward
	 */
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) {
		UploadForm uploadForm = (UploadForm) form;
//		System.out.println(request.getRequestURI());
		 
//		 System.out.println("** "+uploadPath) ; 
//		 System.out.println(request.getSession().getServletContext().getRealPath(""));
		 try {
			 if(uploadForm.getPic().getFileName()==null||uploadForm.getPic().getFileName().equals("")){
				 return mapping.findForward("no");
			 }else{
				 String uploadPath = this.getServlet().getServletContext().getRealPath("/");
				 String dir="\\upload\\"+uploadForm.getName()+"."+(uploadForm.getPic().getFileName().split("\\.")[1]) ;
				 String dir1=uploadPath+dir;
				 OutputStream out=new FileOutputStream(new File(dir1));
					System.out.println(uploadForm.getPic());
					byte b[]=uploadForm.getPic().getFileData();
					out.write(b);
					out.close();
					 request.setAttribute("dir", dir);
			 }
			
			
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
		 return mapping.findForward("ok");
	}
}
