以前一想要学习Java相关知识的时候，就会认为.NET FrameWork的相关技术还没学个通透还夹生饭。现在感觉只会.NET有些单一，需要多掌握几种开发技术，尽管.NET还没达到精通。貌似Hello XXX是很多程序的入门惯例。网上搜的都不全，自己摸索着来一篇Hello Spring MVC 开启我的Java之旅...
开发工具IDEA 2017.1.2
环境JDK1.8\Tomcat8.5.3
项目机构
1.新建项目
2.配置项目
3.src下新建HelloController控制器（属于页面控制器）
package com.cj.springmvc; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; @Controller @RequestMapping(value="hello") public class HelloController { @RequestMapping(method = RequestMethod.GET) public String printHello(ModelMap model) { model.addAttribute("message", "Hello Spring MVC Framework!"); return "hello"; } }
4.WEB-INF下新建文件夹jsp，jsp文件夹内新建hello.jsp文件
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Hello World</title> </head> <body> <h2>${message}</h2> </body> </html>
5.配置web.xml文件
<?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>helloweb</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>helloweb</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
6.配置helloweb-servlet.xml文件
<?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="com.cj"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
7.配置Tomcat，选择自己的Tomcat和JDK安装路径
开始运行
