Hibernate在SqlServer中上传图像

1、sqlServer中photo表字段（int id,image image,varchar contentType）

2、html页面如下：

<form action="uploadPhotoAction.action" method="post" enctype="multipart/form-data" >
         	<input type="hidden" name="userId" value="1"/>	
	上传文件:<input type="file" name="upload" /><br>	  
	<input type="submit" value="提交">	 			  
</form>

 3、uploadPhotoAction如下：

public class UploadPhotoAction {
	@Autowired(required = true) @Qualifier("productManager")
	private ProductManager productManager;
	
	private File upload;
	private String uploadContentType;
	private String uploadFileName;
	
	private Integer userId;

	public File getUpload() {
		return upload;
	}

	public void setUpload(File upload) {
		this.upload = upload;
	}

	public String getUploadContentType() {
		return uploadContentType;
	}

	public void setUploadContentType(String uploadContentType) {
		this.uploadContentType = uploadContentType;
	}

	public String getUploadFileName() {
		return uploadFileName;
	}

	public void setUploadFileName(String uploadFileName) {
		this.uploadFileName = uploadFileName;
	}

	public Integer getUserId() {
		return userId;
	}

	public void setUserId(Integer userId) {
		this.userId = userId;
	}
	
    @Action(value="uploadPhotoAction",results={
			@Result(name="success", location="/success.jsp", type="redirect"),
			@Result(name="error", location="/error.jsp", type="redirect")
    	})
    		
	public String execute(){
    	if( this.getUserId() != 1){
    		return ActionSupport.LOGIN;
    	}
    	productManager.uploadPhoto(upload, uploadContentType);
    	return ActionSupport.SUCCESS;
    }
}

3、service部分

Integer photoId;
		try {						
		   FileInputStream in = new FileInputStream(photo);
		   byte[] b = new byte[in.available()];
		   in.read(b);
		   in.close();
		   Photo image = new Photo();
		   image.setContentType(uploadContentType);
		   image.setImage(Hibernate.createBlob(b));
		   Session  session = sessionFactory.getCurrentSession();
		   session.save(image);
		} catch (FileNotFoundException e) {
			e.printStackTrace();
			return "error";
		} catch (IOException e) {
			e.printStackTrace();
			return "error";
		}
		catch (RuntimeException re) {
			re.printStackTrace();
			throw re;
		}
		return "success";	
	}
