【SpringMVC框架】注解的处理器映射器和适配器配置

package cn.edu.hpu.ssm.controller;

import java.util.ArrayList;
import java.util.List;


import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import cn.edu.hpu.ssn.po.Items;

//注解的Handler类
//使用@Controller来标识它是一个控制器
@Controller
public class ItemsController3 {
  
  //商品查询列表
  //@RequestMapping实现 对queryItems方法和url进行映射，一个方法对应一个url
  //一般建议将url和方法写成一样
  @RequestMapping("/queryItems")
  public ModelAndView queryItems()throws Exception{
    
    //调用Service查找数据库，查询商品列表，这里使用静态数据模拟
    List itemsList=new ArrayList();
    //向List中填充静态数据
    Items items_1 = new Items();
    items_1.setName("联想笔记本22222222");
    items_1.setPrice(6000f);
    items_1.setDetail("ThinkPad T430 联想笔记本电脑！");
    
    Items items_2 = new Items();
    items_2.setName("苹果手机22222222");
    items_2.setPrice(5000f);
    items_2.setDetail("iphone6苹果手机！");
    
    itemsList.add(items_1);
    itemsList.add(items_2);
    
    //返回ModelAndView
    ModelAndView modelAndView=new ModelAndView();
    //相当于request的setAttribut，在jsp页面中通过这个来取数据
    modelAndView.addObject("itemsList",itemsList);
    
    //指定视图
    modelAndView.setViewName("/WEB-INF/jsp/items/itemsList.jsp");


    return modelAndView;
  }
  
  //定义其它方法
  //商品添加
  //商品删除
}
