先在struts-config.xml里面聲明一個DynaActionForm,在做一個關聯的Action
<form-bean name="uploadForm" type="org.apache.struts.action.DynaActionForm" dynamic="true">
<form-property name="filename" type="java.lang.String"/>
<form-property name="uploadfile" type="org.apache.struts.upload.FormFile"/>
</form-bean>
<action
attribute="uploadForm"
input="/form/upload.jsp"
name="uploadForm"
path="/upload"
scope="request"
type="com.gcoresoft.struts.action.UploadAction"
/>
Action代碼如下
/**//*

* Template path: templates/java/JavaClass.vtl
*/
package com.gcoresoft.struts.action;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;

public class UploadAction extends Action 
{
private static final Log log = LogFactory.getLog(UploadAction.class);

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
DynaActionForm uploadForm = (DynaActionForm) form;// TODO Auto-generated method stub
String filename=((String)uploadForm.get("filename")).trim();
FormFile file=(FormFile)uploadForm.get("uploadfile");
if(filename.equals("")||filename==null)
{
filename=file.getFileName();
try {
filename=new String(filename.getBytes("GBK"),"UTF-8");//編碼轉換
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
log.debug("Filename:"+filename);
String filepath="e:\\temp\\";
log.debug("Realpath:"+filepath);
try {
InputStream in=file.getInputStream();
OutputStream out=new FileOutputStream(filepath+filename);
byte[] buffer=new byte[20000];
int n=0;
while((n=in.read(buffer))!=-1)
{
out.write(buffer, 0, n);
}
out.close();
in.close();
log.debug("Upload Successfully");
return mapping.findForward("success");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return mapping.findForward("failure");
}
}
相關的jsp文件
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html"%>
<html>
<head>
<title>JSP for DynaActionForm form</title>
</head>
<body>
<html:form action="/upload" enctype = "multipart/form-data">
filename : <html:text property="filename"/><html:errors property="filename"/><br/>
uploadfile : <html:file property="uploadfile"/><html:errors property="uploadfile"/><br/>
<html:submit/><html:cancel/>
</html:form>
</body>
</html>
這樣基本就可以了。
還有就是在web.xml文件里面聲明了一個Set Character Encoding沒效果，不知道怎么回事，呆會晚上問下人看看是什么問題。
這幾天查了很多資料都無法解決那個問題，很多都提示需要修改源代碼，沒辦法，先拿這個湊合下吧。
在網上還找到一個方法就是將struts升級到1.2，formfile在1.2中解決了中文亂碼這個問題，所以我直接升級到了1.2問題解決。
老bean那里也有一個方法，就是使用
Jakarta 文件上傳類，詳細資料請參考：
