基于配置的Spring MVC3
网上查找的spring mvc3大部分都是基于注射的方式,总感觉注射有点怪怪。不利于后期扩展和项目管理,于是特意写下这篇基于xml配置的Spring MVC3。以供大家參考。
怎么建立web项目和下载相关jar这里就不说了,直接写下关键内容。
1. 所需jar
aopalliance-1.0.0.jar
commons-logging.jar
jsp-api.jar
jstl-1.2.jar
servlet-api.jar
spring-aop-3.2.9.RELEASE.jar
spring-beans-3.2.9.RELEASE.jar
spring-context-3.2.9.RELEASE.jar
spring-context-support-3.2.9.RELEASE.jar
spring-core-3.2.9.RELEASE.jar
spring-expression-3.2.9.RELEASE.jar
spring-web-3.2.9.RELEASE.jar
spring-webmvc-3.2.9.RELEASE.jar
standard-1.1.2.jar
<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">2. web.xml配置</span>
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>baseweb</display-name> <context-param> <param-name>webAppRootKey</param-name> <param-value>web.base</param-value> </context-param> <!-- Spring配置 --> <!-- ====================================== --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 指定Spring Bean的配置文件所在文件夹。默认配置在WEB-INF文件夹下 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/webxml/applicationContext.xml</param-value> </context-param> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/webxml/dispatcher-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> </web-app>
3. 在WEB-INF下新建webxml文件夹,以下新建<span style="font-family: Arial, Helvetica, sans-serif;">dispatcher-servlet.xml和</span><span style="font-family: Arial, Helvetica, sans-serif;">applicationContext.xml</span>文件。
<pre name="code" class="html"><span style="font-family: Arial, Helvetica, sans-serif;">dispatcher-servlet.xml</span>
<span style="font-family: Arial, Helvetica, sans-serif;"> </span>
<span style="font-family: Arial, Helvetica, sans-serif;"></span><pre name="code" class="html"><?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" default-autowire="byName"> <!-- handler 的使用顺序 假设第一个找不到对应的controller, 则会调用第二个 1: ControllerClassNameHandlerMapping 2: BeanNameUrlHandlerMapping --> <bean id="beanNameUrlHandlerMapping" class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"> <property name="order" value="1"></property> </bean> <bean id="webController" class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" > <property name="order" value="2"></property> </bean> <!-- Web请求与视图之间的约定,使用RequestToViewNmaeTranslator --> <bean id="viewNameTranslator" class="org.springframework.web.servlet.view.DefaultRequestToViewNameTranslator"/> <!-- 声明使用的视图技术 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="order" value="1"></property> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> <!-- MultiController -> multi/add.do , multi/list.do --> <bean id="methodNameResolver" class="org.springframework.web.servlet.mvc.multiaction.InternalPathMethodNameResolver" /> <bean id="index" class="com.liuxm.base.web.IndexController"> </bean> </beans>
<span style="font-family: Arial, Helvetica, sans-serif;"> </span>
<span style="font-family: Arial, Helvetica, sans-serif;">applicationContext.xml</span>
<?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:tx="http://www.springframework.org/schema/tx" 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/tx http://www.springframework.org/schema/tx/spring-tx-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"> </beans>
package com.liuxm.base.web; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.AbstractController; public class IndexController extends AbstractController{ private String success; @Override protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception { return new ModelAndView(getSuccess()); } public String getSuccess() { return success; } public void setSuccess(String success) { this.success = success; } }5. 在WEF-INF下新建jsp目录,在jsp新建index.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> This is index page ....... </body> </html>
6. 在tomcat中执行web,输入http://xxxxxxx/xx/index.do
