1.编写jsp文件

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>

    <h3>入门程序</h3>
    <a href="">入门程序</a>
</body>
</html>

2.编写一个控制类

package cn.itcast.controller;
//控制器类
public class HelloController {
    public String sayHello(){
        System.out.println("Hello StringMVC");
        return "success";
    }
}

3.在XML中导入约束

<?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/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

</beans>

4.开启注解扫描

    <!--配置spring创建容器时要扫描的包-->
    <context:component-scan base-package="cn.itcast"></context:component-scan>

5.写请求路径

package cn.itcast.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
//控制器类
@Controller
public class HelloController {
    @RequestMapping(path = "/hello")
    public String sayHello(){
        System.out.println("Hello StringMVC");
        return "success";
    }
}
