SpringMVC学习（一）HelloWorld

1.新建工程

New Project->勾选Spring、SpringMVC

在src目录里新建一个包，新建HiController.java（作为controller部分）

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

@Controller
@RequestMapping("/hi")
public class HiController {
    @RequestMapping("/say")
    public String say(Model model){
        model.addAttribute("name","hyf");
        model.addAttribute("url","fucker");
        return "say";
    }
}

在\web\WEB-INF\jsp目录里新建文件say.jsp（作为Controller部分）

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>title</title>
</head>
<body>
hello world,${name}
<br>
${url}
</body>
</html>

4.配置dispatcher-servlet.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.xsd">

    <context:component-scan base-package="wormday.springmvc.helloworld"/>
    <!--指定视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 视图的路径 -->
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <!-- 视图名称后缀  -->
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

5.配置web.xml（改一下url-pattern）

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>
