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>
