Struts2 上传文件allowedTypes详解
原文地址：http://www.iteye.com/topic/1121677
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 block
- e.printStackTrace();
- }
- }
- private static String getExtention(String fileName) {
- int pos = fileName.lastIndexOf(".");
- return fileName.substring(pos);
- }
- @Override
- public 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" class="jp.co.ricoh.action.upload.FileUploadAction">
- <interceptor-ref name="fileUpload">
- <param name="allowedTypes">
- image/bmp,image/png,image/gif,image/jpeg,image/jpg,
- </param>
- </interceptor-ref>
- <interceptor-ref name="defaultStack"></interceptor-ref>
- <result name="input">/upload/upload.jsp</result>
- <result name="success">/upload/showUpload.jsp</result>
- </action>
- </package>
Upload.jsp
- <%@ 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">

- </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>
但是，我明明上传的文件格式是正确，还是出现：
- Content-Type not allowed: file "09poC_wallpapers.jpg" "upload_1ea6fe4e_13611ac7d7c__8000_00000012.tmp" image/pjpeg

firefox 和 ie 的文件类型区别
| Firefox： |
image/jpeg, image/bmp, image/gif, image/png |
| ie 6： |
image/pjpeg ,image/bmp, image/gif, image/x-png |
| ie 7： |
image/pjpeg, image/bmp, image/gif, image/x-png |
| ie 8： |
image/pjpeg, image/bmp, image/gif, image/x-png |
| Ie 9： |
image/jpeg, image/bmp, image/gif, image/png |
所以在struts.xml配置文件中需要
<param name="allowedTypes">
image/bmp,image/png,image/gif,image/jpeg,image/jpg,
image/pjpeg ,image/bmp, image/gif, image/x-png,
</param>
