一、 导入SpringMVC环境所需基础Jar包
下载 http://pan.baidu.com/s/1jGEAZ9G
spring-aop-3.2.0.RELEASE.jar spring-aspects-3.2.0.RELEASE.jar spring-beans-3.2.0.RELEASE.jar spring-context-3.2.0.RELEASE.jar spring-context-support-3.2.0.RELEASE.jar spring-core-3.2.0.RELEASE.jar spring-expression-3.2.0.RELEASE.jar spring-instrument-3.2.0.RELEASE.jar spring-instrument-tomcat-3.2.0.RELEASE.jar spring-jdbc-3.2.0.RELEASE.jar spring-jms-3.2.0.RELEASE.jar spring-orm-3.2.0.RELEASE.jar spring-oxm-3.2.0.RELEASE.jar spring-test-3.2.0.RELEASE.jar spring-tx-3.2.0.RELEASE.jar spring-web-3.2.0.RELEASE.jar spring-webmvc-3.2.0.RELEASE.jar spring-webmvc-portlet-3.2.0.RELEASE.jar
commons-logging.jar //注:日志jar包
二、 编辑web.xml配置文件
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:com/llqqww/config/springMVC-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup> <!--启动顺序,tomcat一启动就初始化SprinMVC-->
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>注：
init-param 中设置其他配置文件路径，没有init-param默认是在/WEB-INF目录下所有*-servlet.xml文件
本文配置文件springMVC-servlet.xml在src的com.llqqww.config包内
spring配置文件名需与web.xml中的<servlet-name></servlet-name>中一致
三、 添加springMVC-servlet.xml配置文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:mvc="http://www.springframework.org/schema/mvc"
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.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<bean name="/hi/helloworld" class="com.llqqww.controller.HelloWorldController" />
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans> 注：
/hi/helloworld是访问Controller的URL路径、class是该URL访问的Controller
prefix 若是'/',则是用户可直接访问WebRoot下的jsp文件、若是"/WEB-INF/jsp/"，则只能通过Controller映射访问jsp文件(不能直接访问"/WEB-INF"目录下文件)
四、 编写Controller控制器
新建com.llqqww.controller包,创建类HelloWorldController 继承Controller 类，实现handleRequest方法
package com.llqqww.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
public class HelloWorldController implements Controller {
public ModelAndView handleRequest(HttpServletRequest arg0,
HttpServletResponse arg1) throws Exception {
System.out.println("-------Welocome-----");
return new ModelAndView("/welcome");
}
}
五、 在WebRoot目录下建立View文件
welcome.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!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=UTF-8"> <title>Insert title here</title> </head> <body> Welcome~ </body> </html>
六、 访问Controller控制器
启动tomcat部署项目,浏览器访问如:localhost:8080/hi/helloworld 则会看到welcome.jsp文件中的"Welcome~"信息
