尝试调用不存在的方法。超导系统

当我运行 STS（Spring Boot）应用程序时，出现以下错误：

The attempt was made from the following location:      org.apache.catalina.authenticator.AuthenticatorBase.startInternal(AuthenticatorBase.java:1321)

以下方法不存在：

javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;

该方法的类 javax.servlet.ServletContext 可从以下位置获取：

jar:file:/home/talha/.m2/repository/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar!/javax/servlet/ServletContext.class
    jar:file:/home/talha/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/9.0.33/tomcat-embed-core-9.0.33.jar!/javax/servlet/ServletContext.class

它是从以下位置加载的：

file:/home/talha/.m2/repository/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar

ide中的建议是： 行动：

更正应用程序的类路径，使其包含单个兼容版本的 javax.servlet.ServletContext

我猜我的 pom.xml 有问题，代码如下：

导致错误的主要依赖项是：

<dependency>
            <groupId>joda-time</groupId>
            <artifactId>joda-time</artifactId>
        </dependency>

            <artifactId>jsontoken</artifactId>
            <version>1.0</version>
        </dependency>

仅在添加上述依赖项后才出现错误，需要添加依赖项的是以下类：

请帮我解决这个问题。提前致谢

getVirtualServerName() http://tomcat.apache.org/tomcat-9.0-doc/servletapi/javax/servlet/ServletContext.html#getVirtualServerName--被添加到Servlet 3.1，但你包括了servlet-api-2.5.jar是你的应用程序。

Options:

• 更改您的依赖项以包括servlet-api-3.1.jar（或稍后）

• 去除servlet-api-2.5.jar依赖项，因为正确的版本包含在嵌入式 Tomcat 文件中（tomcat-embed-core-9.0.33.jar).

事实上，你永远不应该发货servlet-api.jar与您的应用程序一起使用，因为它将由 Servlet 容器提供。看来你失踪了<scope>provided</scope>在你的依赖标签中servlet-api file.
