spring 框架的配置文件

首先要导入需要的jar包

配置web.xml:

<!-- Spring MVC配置 --><!-- ====================================== --><servlet>    <servlet-name>spring</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <!-- 可以自定义servlet.xml配置文件的位置和名称，默认为WEB-INF目录下，名称为[<servlet-name>]-servlet.xml，如spring-servlet.xml    <init-param>        <param-name>contextConfigLocation</param-name>        <param-value>/WEB-INF/spring-servlet.xml</param-value>&nbsp; 默认    </init-param>    -->    <load-on-startup>1</load-on-startup></servlet><servlet-mapping>    <servlet-name>spring</servlet-name>    <url-pattern>*.jsp</url-pattern>

    <!-- <url-pattern>/</url-pattern> -->
</servlet-mapping><!-- Spring配置 --><!-- ====================================== -->

<listener>   <listenerclass>     org.springframework.web.context.ContextLoaderListener   </listener-class></listener>  <!-- 指定Spring Bean的配置文件所在目录。默认配置在WEB-INF目录下 --><context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:config/applicationContext.xml</param-value></context-param>

配置spring-servlet.xml(spring-servlet这个名字是因为上面web.xml中<servlet-name>标签配的值为spring（<servlet-name>spring</servlet-name>），再加上“-servlet”后缀而形成的spring-servlet.xml文件名，如果改为springMVC，对应的文件名则为springMVC-servlet.xml)：
