SSH中action层的需要实现的几个接口

商城ssh架构 action层

上代码先，实现ModelDriven，可以在jsp中传值不家类名如  user.name,可以直接写成 name

RequestAware, SessionAware, ApplicationAware可以直接在三个内置对象中些数据，map格式

package com.zzu.shopol.action;

import java.lang.reflect.ParameterizedType;
import java.util.HashMap;
import java.util.Map;

import org.apache.struts2.interceptor.ApplicationAware;
import org.apache.struts2.interceptor.RequestAware;
import org.apache.struts2.interceptor.SessionAware;

import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.zzu.shopol.pojo.Account;
import com.zzu.shopol.service.AccountService;
import com.zzu.shopol.service.CategoryService;
import com.zzu.shopol.service.ForderService;
import com.zzu.shopol.service.GoodsService;
import com.zzu.shopol.service.SorderService;
import com.zzu.shopol.util.FileUploadUtil;
