web.xml基本配置描述

先載入一段寫好的web.xml：

<!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>  <display-name>Archetype Created Web Application</display-name>      <!--Spring ApplicationContext 載入 -->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>      <!-- SpringMVC -->    <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/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>          <!-- session逾時定義,單位為分鐘 -->    <session-config>        <session-timeout>30</session-timeout>    </session-config>    <!-- 預設首頁定義 -->    <welcome-file-list>        <welcome-file>index.ftl</welcome-file>        <welcome-file>index.html</welcome-file>    </welcome-file-list></web-app>

web.xml中通過以下配置載入/WEB-INFO/applicationContext.xml（spring 全域設定檔，用來控制spring特性）

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

/WEB-INFO/applicationContext.xml是預設路徑及檔案名稱，如果調整檔案路徑或名稱，需要額外添加以下contextConfigLocation參數：

<context-param>      <param-name>contextConfigLocation</param-name>      <param-value>/WEB-INF/applicationContext-new.xml</param-value> </context-param><listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>

web.xml中通過以下配置載入/WEB-INFO/applicationContext.xml（屬於spring mvc，載入控制器，攔截uri轉寄view）

    <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/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>
