1、依赖包

spring-context、spring-web、spring-webmvc、commons-logging、log4j、javax.servlet-api

配置 web.xml

<!– 使用SpringMvc的核心调度器sevlet配置起来 –>
<!– The front controller of this Spring Web application, responsible for handling all application requests –>
   <servlet>
       <servlet-name>springDispatcherServlet</servlet-name>
       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
       <!– 指定Spring配置文件所在位置 –>
       <init-param>
           <param-name>contextConfigLocation</param-name>
           <param-value>classpath:springmvc.xml</param-value>
       </init-param>
       <load-on-startup>1</load-on-startup>
   </servlet>

   <!– Map all requests to the DispatcherServlet for handling –>
   <!– 指定URL的映射地址 –>
   <servlet-mapping>
       <servlet-name>springDispatcherServlet</servlet-name>
       <url-pattern>/</url-pattern>
       <!– /表示网址根目下的所有静态资源和所有的url地址，但不包括其它servlet ,不要配置/*,/*一般用于配置拦截器(filter)中–>
   </servlet-mapping>

生成springmvc.xml文件

<?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:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
		<!-- 注解所在的基本包 -->
	<context:component-scan base-package="ljd.springMvc"></context:component-scan>
	<!-- 为SpringMVC指定解析器 -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="prefix" value="/WEB-INF/jsp/"></property>
	<property name="suffix" value=".jsp"></property>
	</bean>

</beans>

创建项目结构包

创建控制器

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

@Controller
public class IndexController {
	@RequestMapping("/index")
	public String index() {
		return "index";/* 返回的视图的名字（其实就是jsp中对应的jsp页文文件名） */
		
	}

}
