非注解方式配置springmvc

第一步：放入jar包

 

第二步：配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>springmvc-1</display-name>
  
  <servlet>
  	<servlet-name>springmvc</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>
  	</init-param>
  </servlet>
  
  <servlet-mapping>
  	<servlet-name>springmvc</servlet-name>
  	<url-pattern>*.action</url-pattern>
  </servlet-mapping>
</web-app>

第三步：配置spingmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd">
	
	<!-- 配置handler -->
	<bean id="itemsController" name="/queryItems.action" class="com.hous.controller.ItemsController"/>
	
	<!-- 配置处理器映射器 -->
<!-- 	<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/> -->
	
	<!-- 处理器适配器 -->
<!-- 	<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean> -->
	
	<!-- 视图解析器 -->
<!-- 	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean> -->
</beans>

第四步：编写handler

package com.hous.controller;

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

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

import com.hous.vo.Items;

public class ItemsController implements Controller {

	@Override
	public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
		List<Items> itemsList = new ArrayList<Items>();
		Items items_1 = new Items();
		items_1.setName("联想笔记本");
		items_1.setPrice(6000f);
		items_1.setDetail("联想笔记本是我国重要硬件");
		
		Items items_2 = new Items();
		items_2.setName("苹果手机");
		items_2.setPrice(3000f);
		items_2.setDetail("苹果手机在我国非常流行");
		
		itemsList.add(items_1);
		itemsList.add(items_2);
		
		ModelAndView modelAndView = new ModelAndView();
		modelAndView.addObject("itemsList", itemsList);
		modelAndView.setViewName("index.jsp");
		return modelAndView;
	}
