注意两点：

1、Spring applicationContext先启动，servlet context后加载
2、dispatcher-servlet.xml中定义了控制器映射，使用Controller+RequestMapping注解映射时，相关controller组件扫描要定义在dispatcher-servlet.xml中，而非applicationContext.xml中。

你好：请问web.xml 要怎么配置这两个文件，我将这两个文件放到web-info/spring 这及目录下。我写的配置是这样。
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath*:**/spring/*bean*.xml
</param-value>
</context-param>
<!--
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
-->
<!--  Spring MVC 的Servlet，它将加载WEB-INF/spring/spring-mvc.xml 的 配置文件，以启动Spring MVC模块-->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>>
        classpath*:**/spring/*mvc*.xml
        </param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
但报parsing XML document from ServletContext resource的错误。谢谢
