HelloWorld程序
Step1 编写web.xml文件
<?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"> <display-name></display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet </servlet-class> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <!-- 匹配所有URL --> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
Step2 编写springMVC-servlet.xml（映射文件）
<?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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd"> <!-- spring自动去扫描base-package下面的包或者子包下面的java文件 --> <!-- 如果扫描到有spring的相关注解的类，则把这些类注册为spring的Bean --> <context:component-scan base-package="org.fkit.controller" /> <!-- 视图解析器配置开始 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 前缀 --> <property name="prefix"> <value>/WEB-INF/content/</value> </property> <!-- 后缀 --> <property name="suffix"> <value>.jsp</value> </property> </bean> </beans>
Step3 编写控制器org.fkit.Controller
package org.fkit.controller; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class HelloWorldController { @RequestMapping("/helloWorld") public String helloWorld(Model model) { //model为模型数据，增加属性message,值为:"hello World" model.addAttribute("message", "Hello World"); return "helloWorld"; } }
Step4 WEB-INF/content/目录下创建文件helloWorld.jsp
