Srping MVC项目结构如下：
一、首先创建一个Dynamic Web Project
二、WebContent/WEB-INF/文件夹下新增 web.xml，配置servlet
容器对于web.xml的加载过程是context-param >> listener >> filter >> servlet，本例子中只配置了servlet，其余按默认配置。
<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>Spring MVC Application</display-name> <servlet> <servlet-name>HelloWeb</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 用于配置spring mvc的配置文件的位置和名称，对应的是下一步(步骤三)中的springmvc.xml --> <!-- 也可以不用配置<init-para>，默认的配置文件为/WEB-INF/[servlet-name]-servlet.xml，此项目中为WEB-INF文件夹下新增HelloWeb-servlet.xml --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>WEB-INF/config/springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>HelloWeb</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
二、WebContent/WEB-INF/config文件夹下新增springmvc.xml
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!-- spring可以自动去扫描base-pack下面或者子包下面的java文件，如果扫描到有@Component @Controller@Service等这些注解的类，则把这些类注册为bean --> <context:component-scan base-package="com.mousewheel" /> <!-- 视图解析器，用于将控制器中handler的结构解析为实际的物理视图 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
三、新增Controller，HelloController.java
package com.mousewheel.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("/hello") public class HelloController { @RequestMapping(method = RequestMethod.GET) public void printHello(ModelMap model) { model.addAttribute("message", "Spring MVC Framework!"); } }
四、新增页面，hello.jsp
<%@ page contentType="text/html; charset=UTF-8" %> <html> <head> <title>Hello World</title> </head> <body> <h2>Hello, ${message}</h2> </body> </html>
运行结果:
