首先在spring.xml中,只需要使用
<?xml version="1.0" encoding="UTF-8"?>
-<beans xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans">
<!-- 扫描@Controler @Service -->
<context:component-scan base-package="cn.xwb"/>
</beans>
经过扫描即可直接找到相应的Control类
Control类
package cn.xwb;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.web.HttpRequestHandler;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import cn.item.*;
@Controller
public class ItemController {
@RequestMapping(value="/i.action")
public ModelAndView intemList(){
// 创建页面需要显示的商品数据
List<Items> list = new ArrayList<Items>();
list.add(new Items(1, "1华为 荣耀8", 2399f, new Date(), "质量好!1"));
list.add(new Items(2, "2华为 荣耀8", 2399f, new Date(), "质量好!2"));
list.add(new Items(3, "3华为 荣耀8", 2399f, new Date(), "质量好!3"));
list.add(new Items(4, "4华为 荣耀8", 2399f, new Date(), "质量好!4"));
list.add(new Items(5, "5华为 荣耀8", 2399f, new Date(), "质量好!5"));
list.add(new Items(6, "6华为 荣耀8", 2399f, new Date(), "质量好!6"));
ModelAndView mav = new ModelAndView();
//数据
mav.addObject("itemList", list);
mav.setViewName("/WEB-INF/jsp/itemList.jsp");
return mav;
}
}
web.xml
<?xml version="1.0" encoding="UTF-8"?>
-<web-app version="2.5" id="WebApp_ID" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

-<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
-<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
-<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>

因此使用注解开发十分简单,不需要十分复杂的适配器和映射器,下一阶段是利用SpringMVC整合Mybatis,很难,但是我会坚持,学完整合就是Spring cloud和Spring boot,然后是安卓,IOS…学习,这中间可能会学习maven,加油啦。
