初识spring mvc 框架的搭建
spring mvc：spring提供的一套简洁mvc web框架
参考

http://blog.csdn.net/javabenface/article/details/7405677（spring3.0）
http://www.cnblogs.com/ooi-/p/3535512.html（eclipse搭建web框架）
环境：eclipse(Eclipse Java EE IDE for Web Developers)、tomcat7
jar包列表
spring：不知道那些是必须的，所有都加入
其他：commons-logging-1.1.3.jar、log4j-1.2.15.jar
1，新建controller
package net.ooi.action;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;/** * 用户controller * @author ooi * */@Controllerpublic class UserController { @RequestMapping("user/list") public ModelAndView userList(){ System.out.println("呵呵"); ModelAndView modelAndView = new ModelAndView() ; modelAndView.setViewName("user/userList") ; modelAndView.addObject("title", "123") ; return modelAndView ; }}
2，新建拦截器AccessInterceptor.java、UserInterceptor.java
AccessInterceptor.java示例：
package net.ooi.interceptor;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;/** * 自定义拦截器 */ public class AccessInterceptor extends HandlerInterceptorAdapter { /** * 最后执行，可用于释放资源 */ @Override public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception { System.out.println(getClass()+"afterCompletion"); super.afterCompletion(request, response, handler, ex); } /** * 显示视图前执行 */ @Override public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { System.out.println(getClass()+"postHandle"); super.postHandle(request, response, handler, modelAndView); } /** * Controller之前执行 */ @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { System.out.println(getClass()+"preHandle"); return super.preHandle(request, response, handler); } }
3，新建页面
位置：
内容：
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%><!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=ISO-8859-1"><title>Insert title here</title><script type="text/javascript" src="${pageContext.request.contextPath}/resource/common.js"></script></head><body>user list page /${title}</body></html>
4，新建springmvc-servlet.xml配置文件
新建source folder：src-resources。在src-resources下新建目录META-INF，
然后在META-INF中新建applicationContext.xml、log4j.properties、springmvc-servlet.xml
springmvc-servlet.xml内容：
<?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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" 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 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- 扫描 --> <context:component-scan base-package="net.ooi"/> <!-- 拦截器--> <mvc:interceptors> <bean class="net.ooi.interceptor.AccessInterceptor"></bean><!-- 拦截所有的配置在这里 --> <mvc:interceptor> <mvc:mapping path="/user/*"/> <bean class="net.ooi.interceptor.UserInterceptor"></bean> </mvc:interceptor> </mvc:interceptors> <!-- InternalResourceViewResolver为spring mvc默认的ViewResolver--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/view/"></property> <property name="suffix" value=".jsp"></property> </bean> </beans>5，配置web.xml
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"><!-- spring --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:/META-INF/applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- spring mvc --> <servlet> <servlet-name>spring-mvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:/META-INF/springmvc-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring-mvc</servlet-name> <url-pattern>*.action</url-pattern> </servlet-mapping> <!-- log --> <context-param> <param-name>webAppRootKey</param-name> <param-value>springmvc01.root</param-value> </context-param> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:/META-INF/log4j.properties</param-value> </context-param> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener><!-- 编码 --> <filter> <filter-name>CharsetFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharsetFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list></web-app>
6，访问地址http://localhost:8888/springmvc01/user/list.action
ok，结束
总算有了一点感觉
