1、导致原因：

如同上面说的，启动Tomcat之后，项目初始化找不到配置文件dispatcher-servlet.xml。

1.1、配置文件命名问题

web.xml文件中配置的servlet名字和springmvc配置文件的名字不一样，修改成一样即可。

这里要注意的是：的名字默认为servlet-name 的值-servlet.xml，所以我们需要删除第一张图中dispatcher-servlet后面的“-servlet”部分，因为这个部分是默认就有的。

springmvc的配置文件是：dispatcher-servlet.xml

servlet-name配置是:

    <servlet>        <servlet-name>dispatcher</servlet-name>//这里不能写成dispatcher-servlet，因为 -servlet是默认就有的！！！        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>dispatcher</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping>

1.2、Spring容器启动问题

Spring容器启动的问题，没有配置好启动的spring配置文件。

<context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:applicationContext.xml</param-value>    </context-param>

这个文件的映射配置是必须的，而且命名不能自定义，必修是 <param-name>contextConfigLocation</param-name>
