图片上传(ssh)

项目中需添加照片:该方式采用的是存放相对路径
页面:
<form action="addTechnicalsupport.action" id="form" method="post"  enctype="multipart/form-data">
<!--enctype="multipart/form-data" 必须-->
   <td align="right" bgcolor="#ddeefc" class="STYLE1" >照片：</td>
        <td align="center" class="STYLE1">
        <input type="file" name="myPhoto" id="myPhoto"    style="width:95%" />
   </td>
</form>
对应的action
public class TechnicalsupportAction extends CommonAction {
     private File myPhoto; //上传的照片
      private String myPhotoFileName;
     private Technicalsupport technicalsupport; //对象
     //上传照片的全名,myPhotoFileName=myPhoto+FileName 自动会得到照片的名称
     
      public String addObject(){
          String end = myPhotoFileName.substring(myPhotoFileName.indexOf(".")); //得到图片后缀名
String newFileName = sdf.format(new Date()) + end ; //给图片取一个新名称
    
if(end.equals(".bmp") || end.equals(".jpg") || end.equals(".gif")){
String photeAbsolutePath = ServletActionContext.getServletContext().getRealPath("/")+"dataDirectory/temp/"+newFileName; //图片的相对路径(图片上传到服务器后存放的位置)
File tempFile = new File(photeAbsolutePath);
FileUtil.copyFile(myPhoto, tempFile); //拷贝文件

String photoRelativePath = request.getContextPath()+"/dataDirectory/temp/"+newFileName; //绝对路径 存放在数据库中

technicalsupport.setPhoto(photoRelativePath); //对象设置路径
//保存对象
}


     }

       public String getMyPhotoFileName() {
return myPhotoFileName;
      }
public void setMyPhotoFileName(String myPhotoFileName) {
this.myPhotoFileName = myPhotoFileName;
}

public File getMyPhoto() {
