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" %>

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
| 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>
?
