Spring Boot中Servletapi的多种实现

Question

试图调用方法javax.servlet.ServletContext.getVirtualServerName（）Ljava / lang / String;但它不存在。它的类javax.servlet.ServletContext可从以下位置获得：

jar:file:/C:/Users/ssen/.m2/repository/org/mortbay/jetty/servlet-api-2.5/6.1.12/servlet-api-2.5-6.1.12.jar!/javax/servlet/ServletContext.class
jar:file:/C:/Users/ssen/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/9.0.16/tomcat-embed-core-9.0.16.jar!/javax/servlet/ServletContext.class

它是从以下位置加载的：

file:/C:/Users/ssen/.m2/repository/org/mortbay/jetty/servlet-api-2.5/6.1.12/servlet-api-2.5-6.1.12.jar
