SpringMvc注解方式开发入门

编写java文件

package com.cloud.po;

import java.util.Date;

publicclass Items {

    private Integerid;

    private Stringname;

    private Float price;

    private Stringpic;

    private Datecreatetime;

    private Stringdetail;

    publicInteger getId() {

        returnid;

    }

    publicvoid setId(Integer id) {

        this.id = id;

    }

    public String getName() {

        returnname;

    }

    publicvoid setName(String name) {

        this.name = name ==null ? null : name.trim();

    }

    public Float getPrice() {

        returnprice;

    }

    publicvoid setPrice(Float price) {

        this.price = price;

    }

    public String getPic() {

        returnpic;

    }

    publicvoid setPic(String pic) {

        this.pic = pic ==null ? null : pic.trim();

    }

    public Date getCreatetime() {

        returncreatetime;

    }

    publicvoid setCreatetime(Date createtime) {

        this.createtime = createtime;

    }

    public String getDetail() {

        returndetail;

    }

    publicvoid setDetail(String detail) {

        this.detail = detail ==null ? null : detail.trim();

    }

}

编写springmvc配置文件

   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:mvc="http://www.springframework.org/schema/mvc"

      <!--注解开发SpringMvc模式 -->

      <!--注解映射器 -->

      <beanclass="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>

      <!--注解适配器 -->

      <beanclass="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/>

      <!--可以代替上面2个配置 :还会默认加载许多参数绑定的方法，实际开发中的选择-->

      <!--

      <mvc:annotation-driven></mvc:annotation-driven>

       -->

      <!--可以扫描controller、service、...

        这里让扫描controller，指定controller的包

      -->

      <context:component-scanbase-package="com.cloud.ctroller"></context:component-scan>

</beans>

编写Handler

package com.cloud.ctroller;

import java.util.ArrayList;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.servlet.ModelAndView;

import com.cloud.po.Items;

@Controller

publicclass ItemController2{

   @RequestMapping("/queryItems")

   public ModelAndView queryItems(HttpServletRequest request,

         HttpServletResponse response)throws Exception {

      //创建几条静态数据

      List<Items> itemsList = new ArrayList<Items>();

      //向list中填充静态数据    

      Items items_1 = new Items();

      items_1.setName("联想笔记本");

      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");

      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();

      modelAndView.addObject("itemsList", itemsList);

      //指定试图

      modelAndView.setViewName("/WEB-INF/jsp/items/itemsList.jsp");

      return modelAndView;

   }

}

前端展示页面
