1.cope jar包到lib中
2.配置web.xml文件
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<!-- Map all requests to the DispatcherServlet for handling -->
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
3.在web-inf中创建springmvc的配置文件springmvc-servlet.xml
分别配置注解驱动、扫描器、视图解析器
<!-- springmvc注解驱动 -->
<mvc:annotation-driven/>
<!-- 扫描器 -->
<context:component-scan base-package="com.tideway.springmvc"></context:component-scan>
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
4.创建发送请求页面index.jsp
<form action="hello.do" method="post">
ID:<input type="text" name="userName"/>
<input type="submit" value="submit"/>
</form>
5.创建控制器HelloWorld.java
package com.tideway.springmvc;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloWorld {
@RequestMapping(value="/hello.do")
public String hello(String userName,Model model){
System.out.println(userName);
model.addAttribute("helloworld", "Hello:"+userName);
return "success";
}
}
6.在WebContent文件夹下创建views文件夹下创建响应页面success.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!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>Insert title here</title>
</head>
<body>
<!-- el方式 -->
<h1>${helloworld }</h1>
</body>
</html>
