Tomcat 启动和停止：java.lang.NoSuchMethodError: javax.servlet.ServletContext.getClassLoader()Ljava/lang/ClassLoader

如何解决Tomcat 启动和停止：java.lang.NoSuchMethodError: javax.servlet.ServletContext.getClassLoader()Ljava/lang/ClassLoader

当我像“启动 catalina”这样的 cmd 启动 tomcat 时，另一个 cmd 终端打开，然后出现下面给出的错误 iis。如何解决这个问题？

解决方法

java.lang.NoSucMethodError 当 Java 代码尝试调用类中不存在的方法时出现，这可能是静态或非静态方法。
