在WEB-INF创建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"
xmlns:context="http://www.springframework.org/schema/context"

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-4.0.xsd

<!-- 配置自动扫描的包 -->
<context:component-scan base-package="com.zjq.springmvc"></context:component-scan>
<!-- 配置视图解析器 如何把handler 方法返回值解析为实际的物理视图 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name = "prefix" value="/WEB-INF/views/"></property>
<property name = "suffix" value = ".jsp"></property>
</bean>
</beans>
在WebContent下建index.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>界面标题</title>
</head>
<body>
<a href="helloworld">hello world</a>
</body>
</html>
在WEB-INF下建views文件夹再在文件夹下建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=ISO-8859-1">
<title>成功界面</title>
</head>
<body>
<h4>恭喜您成功了</h4>
</body>
</html>
创建一个包名,我的包名com.zjq.springmvc.handlers,下面创建一个HelloWorld的类
package com.zjq.springmvc.handlers;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloWorld {
@RequestMapping("/helloworld")
public String HelloWorld() {
// TODO Auto-generated constructor stub
System.out.println("hello world");
return "success";
}
}
包名要在springmvc.xml中改
程序代码
点击运行即可,运行效果图
