java - Spring Rest API 中的日期时间格式

Question

我无法运行应用程序，其显示错误如下，

---

应用程序无法启动

---

描述：

试图调用不存在的方法。尝试是从以下位置进行的：

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 可从以下位置获得：

jar:file:/D:/Comau_Mes/datemes/lib/javax.servlet.jar!/javax/servlet/ServletContext.class
jar:file:/C:/Users/YASH/.m2/repository/javax/servlet/javax.servlet-api/3.1.0/javax.servlet-api-3.1.0.jar!/javax/servlet/ServletContext.class
jar:file:/C:/Users/YASH/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/9.0.35/tomcat-embed-core-9.0.35.jar!/javax/servlet/ServletContext.class

它是从以下位置加载的：

file:/D:/Comau_Mes/datemes/lib/javax.servlet.jar

行动：

更正应用程序的类路径，使其包含一个兼容的 javax.servlet.ServletContext 版本

进程以退出代码 0 结束
