java - 如何修复 org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping 中未找到类的异常？

Question

我正在运行一个 Maven 应用程序，它不断给我一个类未找到的 org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping 异常。

Tomcat 给我以下严重错误。

在我的 pom.xml 文件中，我包含了这些依赖项来解决这个问题。

 <dependency>
           <groupId>org.springframework</groupId>
           <artifactId>spring-context</artifactId>
           <version>5.1.2.RELEASE</version>
       </dependency>
       <dependency>
       <groupId>org.springframework</groupId>
       <artifactId>spring-web</artifactId>
       <version>5.1.2.RELEASE</version>
   </dependency>
          <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>5.1.2.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>5.1.2.RELEASE</version>
        </dependency>

我的 dispatcher-servlet.xml 文件包含处理程序的 bean

<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/>

然后在我的 web.xml 文件中引用它:

    <servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>2</load-on-startup>
</servlet>

我的项目使用 1.8 源/二进制格式。该项目将运行并出现此错误，这让我有点抓狂，我担心它可能会导致我没有看到的问题。

Answer 1

Spring 5.1.2 没有这个类。
