第一次使用web应用，创建了一个简单的springboot restapi，在本地运行良好。通过将war文件复制到/webapps/目录，将war部署到tomcat服务器，并重新启动tomcat。我通过打开tomcat web应用程序管理器页面检查是否成功，并可以看到列出的应用程序：
http://1xx...：8080/经理/
单击“开始”使其运行时，会出现以下错误：

FAIL - Application at context path [/first_restapi] could not be started

我四处搜索，大多数答案都建议确保包含所有pom文件依赖项，并检查日志。我检查了tomcat服务器上的日志，发现以下错误：

Exception sending context initialized event to listener instance of class 
[org.springframework.web.context.ContextLoaderListener]
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: 
Unable to locate Spring NamespaceHandler for XML schema namespace 
[http://www.springframework.org/schema/security]
Offending resource: ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml]

我没有包含servlet-context.xml文件，因为教程没有显示该文件。但我还是添加了它，仍然得到了相同的错误。有人能帮忙解决这个问题吗？
