首先要有一个index.jsp页面：
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h3>入门程序</h3>
<a href="hello">入门程序</a>
</body>
</html>
web.xml中进行前端控制器的配置：
<!--前端控制器配置-->
<servlet>
<servlet-name>dispatcherServlet</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>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
接着写控制类：
package net.togogo.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
* 控制类
*/
@Controller
public class HelloController {
@RequestMapping(path = "/hello")//请求映射
public String sayHello(){
System.out.println("Hello springmvc!");
return "success";
}
}
success.jsp:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h3>入门成功了！</h3>
</body>
</html>
接着在sprinigmvc.xml中配置：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="

http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<!--开启注解扫描-->
<context:component-scan base-package="net.togogo"></context:component-scan>
<!--视图解析器-->
<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!--配置文件所在目录-->
<property name="prefix" value="/WEB-INF/pages/"></property>
<!--配置文件的后缀名-->
<property name="suffix" value=".jsp"></property>
</bean>
<!--开启spinrMVC框架对注解的支持-->
<mvc:annotation-driven/>
</beans>
