Spring与struts整合

      今天介绍Spring与struts的整合 web项目，整合目的是为了解决web每次加载都需要加载配置文件引起的消耗时间的问题，整合之后我们运行服务器后会自动加载xml文件，减少时间的浪费。

      废话不多说首先第一步先导入Jar包

    下面是web.xml的配置

<?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_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>spring_day02_webdemo</display-name> <!-- 指定配置文件的位置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:bean1.xml</param-value> </context-param> <!-- struts的配置 -->> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter </filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <!-- ContextLoaderListener 要先配spring-web-source.jar 并且要指定加载文件的位置 --> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <welcome-file-list> <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>

 

struts.xml

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN" "http://struts.apache.org/dtds/struts-2.5.dtd"> <struts> <package name="demo1" extends="struts-default" namespace="/"> <action name="userAction" class="cn.incast.action.UserAction"> </action> </package> </struts>

applicationContext.xml

<?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:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd" > <bean id="userDao" class="cn.incast.Dao.UserDao"></bean> <bean id="userService" class="cn.incast.Service.UserService"> <property name="userDao" ref="userDao"> </property> </bean> </beans>

将这三个配置结束后，便完成了spring与Web的整合。

最后我们运行服务器发现 确实加载了xml文件
