SSH整合后Struts2上传功能失效

具体原因是Action中接不到值，但是将上传功能单独拿出来运行成功（不信自己拷贝代码来试），因此排除代码问题，整个项目的其他功能正常运行，在就是控制台没有报错信息，求教高手问题出在哪里？

由于Strust.xml 中配置太多这里就只贴上传代码
[code="java"]

这里是fileAction[code="java"]package com.role.action;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

public class fileAction extends ActionSupport {
//路径名
private String inputPath;

private File photo;

private String photoFileName;

private String photoContentType;

private String caption;


public String getInputPath() {
    return inputPath;
}

public void setInputPath(String inputPath) {
    this.inputPath = inputPath;
}

public File getPhoto() {
    return photo;
}

public void setPhoto(File photo) {
    this.photo = photo;
}

public String getPhotoFileName() {
    return photoFileName;
}

public void setPhotoFileName(String photoFileName) {
    this.photoFileName = photoFileName;
}

public String getPhotoContentType() {
    return photoContentType;
}

public void setPhotoContentType(String photoContentType) {
    this.photoContentType = photoContentType;
}

public String getCaption() {
    return caption;
}

public void setCaption(String caption) {
    this.caption = caption;
}

public String execute() throws Exception {
    System.out.println("文件描述+++++++"+caption);
    if (photo != null) {
        System.out.println(photo.length());
        System.out.println(photoFileName);

        FileInputStream fis = new FileInputStream(photo);
        String outfile = ServletActionContext.getServletContext()
                .getRealPath("/upload")
                + "/" + photoFileName;
        System.out.println(outfile);
        FileOutputStream fos = new FileOutputStream(outfile);

        byte[] bytes = new byte[2048 * 8];
        int len;
        while ((len = fis.read(bytes)) != -1) {
            fos.write(bytes, 0, len);
        }
        fis.close();
        fos.close();
    }
    return "input";

}

public String downFile()throws Exception{


    return"downfile";
}
/**
 * 下载
 * @return
 * @throws Exception
 */
public InputStream getTargetFile() throws Exception{
    return ServletActionContext.getServletContext().
            getResourceAsStream("/upload"+photoFileName);

}

}

最后是JSP[code="java"]<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<body>
    <s:form action="fileAction" method="post" theme="simple"
        enctype="multipart/form-data">
        <!-- 测试文件上传 -->
        <s:file key="photo" label="图片文件"></s:file>
        <s:textfield key="caption" label="描述"></s:textfield>
        <s:submit value="测试按钮"></s:submit>
    </s:form>
</body>

[/code]
下面是控制台仅有的信息但是我感觉没多大关系的说，可是运行啦四次无解- -[code="java"]文件描述+++++++null

我给你贴我做的
[code="jsp"][/code]
User类中
[code="java"]
private String savePath;
private File userImage;
private String userImageFileName;
private String contentType;[/code]

在Action中添加User属性，然后只用user中的属性就可以了。
[code="java"]if(user.getUserImage() != null){
String url = ServletActionContext.getRequest().getRealPath(savePath);
String imageFileName = new Date().getTime() + getExtention(user.getUserImageFileName());
File imageFile = new File(url+"/"+imageFileName);
int BUFFER_SIZE = 16 * 1024;
try {
InputStream in = null ;
OutputStream out = null ;
try {

in = new BufferedInputStream( new FileInputStream(user.getUserImage()), BUFFER_SIZE);
out = new BufferedOutputStream( new FileOutputStream(imageFile), 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) {
e.printStackTrace();
}[/code]
[quote]ServletActionContext.getServletContext().

getResourceAsStream("/upload"+photoFileName);[/quote]
xml中的参数没有加“/”,我看你上面的路径在xml中都配置了为什么在取路径的时候还写死呢？
