Struts2文件上传，基本的配置如下：

UploadFileAction

Java代码

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();
}
}

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：

Xml代码

<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>

<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

Java代码

<%@ 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">

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
