我从这里读了很多与我的案子有同样问题的话题，但没有找到解决我问题的方法。这是我使用命名空间

的servlet配置

web.xml配置

当我运行我的应用程序时，没有发现任何错误，但在堆栈跟踪中它没有显示通知控制器已加载的文本行。所以当我点击链接时，我收到404错误。有人可以帮帮我吗？！

您没有分享如何启动应用程序。

对于任何Spring Web应用程序，您必须在应用程序中提供DispatcherServlet的配置。

方法1 您可以将以下映射放在web.xml文件中

 <servlet>
    <servlet-name>myWebApp</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 </servlet>
 <servlet-mapping>
    <servlet-name>myWebApp</servlet-name>
    <url-pattern>/</url-pattern>
 </servlet-mapping>

方法2 您可以注册实现接口WebApplicationInitializer的bean，并可以以编程方式注册DispatcherServlet

现在bean配置文件名应为{servlet-name} -servlet.xml

因此对于上面的servlet，bean配置文件名应该是myWebApp-servlet.xml

或者如果您想自定义bean配置文件的名称，那么您可以在web.xml中提及它，如下所示

 <servlet>
    <servlet-name>myWebApp</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring-mvc-config.xml</param-value>
    </init-param>
 </servlet>
 <servlet-mapping>
    <servlet-name>myWebApp</servlet-name>
    <url-pattern>/</url-pattern>
 </servlet-mapping>

删除pom.xml文件中的log4j12依赖项解决了我的问题。

<dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
