Struts2模型驱动封装

平常写一下小东西，用到模型驱动封装，简直方便的不要不要的。
action页面

package Action;

import entity.Product;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import org.apache.struts2.ServletActionContext;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

public class Product_Action extends ActionSupport implements ModelDriven<Product>{
    private Product product=new Product();
    @Override
    public Product getModel() {
        return product;
    }
    public String execute(){
        HttpServletRequest request= ServletActionContext.getRequest();
        HttpSession session=request.getSession();
        session.setAttribute("product",product);
        return SUCCESS;
    }
}

两个jsp页面
