先创建一个空白新项目，再右击项目处添加框架支持
src处新建一个package，WEB-INF下新建一个jsp文件夹存放jsp文件
文件目录如下
新建一个class TestController 内容如下
package test.springmvc.helloworld;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestParam;
@Controller
@RequestMapping("/test") //类中所有响应请求的父路径
public class TestController {
@RequestMapping("/index") //此处的函数通过该路径响应
public String helloworld(@RequestParam(value = "id") String id, Model model){
model.addAttribute("url","http://www.baidu.com/"); // 指定Model的值
model.addAttribute("id",id);
return "/WEB-INF/jsp/helloworld.jsp";
}
}
@RequestParam(value = "id")用于获取传参id值 通过Model将变量传入视图
helloworld.jsp处的内容为
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
Hello World
<br/>id:${id}
<br/>url:${url}
</body>
</html>配置dispatcher-servlet.xml设置包查找
<?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.xsd">
<context:component-scan base-package="test.springmvc.helloworld"/>
</beans>
接着配置web.xml 修改url-pattern即映射的url路径
下面对tomcat进行配置，以启动程序
先配置Artifact
单击Add Configuration
启动之后会在浏览器打开idea提供的demo
访问http://localhost:8080/test/index?id=111
