一个合格的程序员，请注意细节。

Struts2文件上传

Struts2文件上传，本来很简单却很久没写了，犯了一致命错误

一、写action类

package com.struts.action;

import java.io.File;

import com.opensymphony.xwork2.ActionSupport;

public class DownActionextends ActionSupport {

/**

private static final long serialVersionUID = 1L;

//文件为xxx

private File uploadFile;

//file类型的属性名称必须为xxxFileName

private String uploadFileFileName;

//上传文件的类型类型必须为xxxFileContentType

private String uploadFileFileContentType;

public String getUploadFileFileName() {

return uploadFileFileName;

}

public void setUploadFileFileName(String uploadFileFileName) {

this.uploadFileFileName = uploadFileFileName;

}

public String getUploadFileFileContentType() {

return uploadFileFileContentType;

}

public void setUploadFileFileContentType(String uploadFileFileContentType) {

this.uploadFileFileContentType = uploadFileFileContentType;

}

public File getUploadFile() {

return uploadFile;

}

public void setUploadFile(File uploadFile) {

this.uploadFile = uploadFile;

}

public String upFile(){

System.out.println(uploadFile);

if(uploadFile!=null){

String dataDir = "d:\\upload\\";

File saveFIle = new File(dataDir,uploadFileFileName);

uploadFile.renameTo(saveFIle);

}else{

return INPUT;

}

return SUCCESS;

}

二、Struts2配置文件设置

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">

<result>/success.jsp</result>

<interceptor-ref name="defaultStack">

<param name="fileUpload.allowedTypesSet">image/gif,image/jpeg,image/png</param>

</interceptor-ref>

</action>

</package>

</struts>

三、前台页面展示

<html>

<body>

上传文件：<input type="file" name="uploadFile">

</form>

</body>

</html>
