SpringMVC框架搭建

1.导入JAR包

2.配置web.xml配置文件

  <servlet>
  	<servlet-name>SpringMVC</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  </servlet>
  <servlet-mapping>
  	<servlet-name>SpringMVC</servlet-name>
  	<url-pattern>/*</url-pattern>
  </servlet-mapping>

3.编写XX-servlet.xml配置文件（SpringMVC配置文件）

XX根据<servlet-name>SpringMVC</servlet-name>决定的

所以XX=SpringMVC,所以SpringMVC-servlet.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"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">
        <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
        <bean name="/hello.action" class="com.zhangpn.Controller.MyController"></bean>
</beans> 

4.写出

com.zhangpn.Controller.MyController

package com.zhangpn.Controller;

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

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

public class MyController extends AbstractController {

	@Override
	protected ModelAndView handleRequestInternal(HttpServletRequest req, HttpServletResponse resp) throws Exception {
		
		System.out.println("hello controller");
		
		return null;
	}
	
}

5.运行一下
