struts实现文件上传示意性源文件

1、jsp页面：

<html:form action="/upload.do" method="post" enctype="multipart/form-data">

标题：<html:text property="title" value=""></html:text><br>

文件：<html:file property="file" value="" onchange="return checkName(this);"></html:file><br>

<html:button property="btn1" value="提交" onclick="return validate();" />

</html:form>

2、ActionForm

package com.solid.upload;

import org.apache.struts.action.ActionForm;

import org.apache.struts.upload.FormFile;

public class UploadForm extends ActionForm {

//文件标题

private String title;

//上传文件

private FormFile file;

public FormFile getFile() {

return file;

}

public void setFile(FormFile file) {

this.file = file;

}

public String getTitle() {

return title;

}

public void setTitle(String title) {

this.title = title;

}

}

3、Action

package com.solid.upload;

import java.io.FileOutputStream;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

import org.apache.struts.action.ActionMapping;

import org.apache.struts.actions.DispatchAction;

import org.apache.struts.upload.FormFile;

public class UploadAction extends DispatchAction {

public ActionForward upload(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {

UploadForm uploadForm = (UploadForm)form;

//标题

String title = uploadForm.getTitle();

//文件

FormFile file = uploadForm.getFile();

try {

if(file != null) {

System.out.println("fileName=" + file.getFileName() + " fileSize=" + file.getFileSize());

String path = "D:" + java.io.File.separator + file.getFileName();

FileOutputStream fos = new FileOutputStream(path);

fos.write(file.getFileData());

fos.flush();

fos.close();

}

} catch (Exception e) {

e.printStackTrace();

}

return mapping.findForward("success");

}

}
