Struts2 上传文件allowedTypes详解

Struts2文件上传，基本的配置如下：

UploadFileAction

package jp.co.ricoh.action.upload;import java.io.BufferedInputStream;import java.io.BufferedOutputStream;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.InputStream;import java.io.OutputStream;import java.util.Date;import org.apache.struts2.ServletActionContext;import com.opensymphony.xwork2.ActionSupport;public class FileUploadAction extends ActionSupport {/** *  */private static final long serialVersionUID = 7944571812664822722L;private static final int BUFFER_SIZE = 16 * 1024;private File file;private String contentType;private String fileName;private String imageFileName;private String caption;public File getFile() {return file;}public void setFile(File file) {this.file = file;}public String getFileContentType() {return contentType;}public void setFileContentType(String contentType) {this.contentType = contentType;}public String getFileFileName() {return fileName;}public void setFileFileName(String fileName) {this.fileName = fileName;}public String getImageFileName() {return imageFileName;}public void setImageFileName(String imageFileName) {this.imageFileName = imageFileName;}public String getCaption() {return caption;}public void setCaption(String caption) {this.caption = caption;}public static int getBufferSize() {return BUFFER_SIZE;}private static void copyFile(File src, File dest) {try {InputStream in = null;OutputStream out = null;try {in = new BufferedInputStream(new FileInputStream(src),BUFFER_SIZE);out = new BufferedOutputStream(new FileOutputStream(dest),BUFFER_SIZE);byte[] buffer = new byte[BUFFER_SIZE];while (in.read(buffer) > 0) {out.write(buffer);}} finally {if (null != in) {in.close();}if (null != out) {out.close();}}} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}private static String getExtention(String fileName) {int pos = fileName.lastIndexOf(".");return fileName.substring(pos);}@Overridepublic String execute() throws Exception {imageFileName = new Date().getTime() + getExtention(fileName);File imageFile = new File(ServletActionContext.getServletContext().getRealPath("/uploadFile") + "/" + imageFileName);System.out.println(imageFile.getName());copyFile(file, imageFile);return super.execute();}}

?struts.xml配置如下：

<package name="upload" namespace="/" extends="struts-default"><action name="FileUploadAction" name="code"><%@ page language="java" contentType="text/html; charset=utf-8"    pageEncoding="utf-8"%><%@ taglib prefix="s" uri="/struts-tags" %>    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><title>Struts2 File Upload</title></head><body><s:fielderror></s:fielderror><s:form action="FileUploadAction" method="post" enctype="multipart/form-data"><s:file name="file" label="Image File"></s:file><s:textfield name="caption" label="Caption"></s:textfield><s:submit></s:submit></s:form></body></html>
