跟Spring有关的,在web.xml的配置

Spring MVC的前端控制器，用来处理所有请求

	<!-- Handles all requests into the application -->
	<servlet>
		<servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>
				/WEB-INF/spring/appServlet/servlet-context.xml
			</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

contextConfigLocation如果不写的时候，默认为{servlet-name}-context.xml
