struts2实现文件图片上传
我的JSP页面代码如下：
<body><form name="myform" method="post" action="/s2/user/fileAction.action" enctype="multipart/form-data"> <table align="center"> <tr> <td colspan="2">文件上传</td> </tr> <tr> <td>上传的文件:</td> <td><input type="file" name="myfile"/></td> </tr> <tr> <td>用户编号:</td> <td><input type="text" name="userId"/></td> </tr> <tr> <td>用户姓名:</td> <td><input type="text" name="userName"/></td> </tr> <tr> <td colspan="2"><input type="submit" value="上传"/></td> </tr> </table> </form></body>
我的Action如下：
package com.xll.util;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.InputStream;import java.io.OutputStream;import com.opensymphony.xwork2.ActionSupport;public class FileAction extends ActionSupport{public File myfile;public String myfileFileName;public String myfileContentType;public String userId;public String userName; public String execute(){ InputStream in = null; OutputStream out = null; try {in = new FileInputStream(myfile);out = new FileOutputStream("d:/temp/"+myfileFileName);int str = -1;while((str=in.read()) != -1){out.write(str);//str = in.read();}} catch (Exception e) {e.printStackTrace();} finally{try {out.flush();in.close();out.close();} catch (Exception e) {e.printStackTrace();}} System.out.println("userId="+userId+",userName="+userName); System.out.println("myfileFileName="+myfileFileName+",myfileContentType="+myfileContentType); return this.SUCCESS; }}struts.xml中的配置：
<action name="fileAction" name="code"><constant name="struts.i18n.encoding" value="gb2312"></constant>
页面编码统一为gbk 上传后的文件未出现乱码！
