SpringMVC学习之环境搭建（一）-优快云博客

本文介绍了一个简单的 Spring MVC 应用程序实现，该应用通过点击链接显示“Hello World”消息，并返回一个名为“success”的字符串，进而加载 success.jsp 页面。

整体代码结构：

jdk1.8.0+tomcat9.0

index.jsp

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Index</title>
</head>
<body>
	<a href="sayHello">Hello World</a>
</body>
</html>

HelloWorld.java

package com.kinsey.woo.springmvc.controller;

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

@Controller
public class HelloWorld {

	
	@RequestMapping("/sayHello")
	public String sayHello(){
		System.out.println("Hello World");
		return "success";
	}
}

web.xml

		<url-pattern>/</url-pattern>
	</servlet-mapping>
        
        
        
        
</web-app>

springmvc.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"

	<!-- 配置包扫描 -->
	<context:component-scan base-package="com.kinsey.woo.springmvc.*">
	</context:component-scan>
	
	
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/JSP/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
	

</beans>

success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>SUCCESS</title>
</head>
<body>
	<h1>SUCCESS</h1>

</body>
</html>

结果:
