Web.xml配置多个*.xml模块化

对于在web.xml配置文件中配置ApplicationContext的自动创建有两种策略:
1.利用ServerContextListener;

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/daoContext.xml,/WEB-INF/applicationContext.xml</param-value>
	</context-param>


    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

	<servlet>
		<servlet-name>test</servlet-name>
		<servlet-class>lee.SpringTestServlet</servlet-class>
	</servlet>

    <servlet-mapping>
		<servlet-name>test</servlet-name>
		<url-pattern>/test</url-pattern>
    </servlet-mapping>

</web-app>

2.采用load-on-startup servlet实现

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>

	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/daoContext.xml,/WEB-INF/applicationContext.xml</param-value>
	</context-param>

	<servlet>
		<servlet-name>context</servlet-name>
		<servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet>
		<servlet-name>test</servlet-name>
		<servlet-class>lee.SpringTestServlet</servlet-class>
	</servlet>

    <servlet-mapping>
		<servlet-name>test</servlet-name>
		<url-pattern>/test</url-pattern>
    </servlet-mapping>

</web-app>
