Tomcat 404 java spring mvc - Codes Helper - Programming Question Answer

web.xml

    <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

mvc-dispatcher-servlet.xml

    <context:component-scan base-package="com.XXX.controller"/>

    <!-- (jsimage) -->
    <mvc:default-servlet-handler/>

    <!--  -->
    <mvc:annotation-driven/>

    <!--ViewResolver -->
    <!--ServletJSP-->
    <bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

I think the code and configuration should be fine. At startup, it is tomcat 404

. It is also useless to change / to / * in accordance with the solution of related problems .

thinks it may be a problem with tomcat

the following is the log at startup:
