Does the log report an error when springboot2+apache cxf is deployed to tomcat?

using springboot2 + cxf to develop web service service, debugging on idea is not a problem. If you package it into war and deploy it to tomcat, the error is as follows. Have you ever encountered this problem? is there a solution?

Tomcat cxf springboot
Apr.11,2021

solved. An error was reported here 

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cxf-org.apache.cxf.spring.boot.autoconfigure.CxfProperties': Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/el/ELManager

then I add the following to the pom file of the project 

        <dependency>
            <groupId>javax.el</groupId>
            <artifactId>javax.el-api</artifactId>
            <version>3.0.0</version>
        </dependency>

then it didn't work, and then I found out the reason. Because the version of tomcat is tomcat7, you need to put the jar package javax.el-api-3.0.0.jar in the lib of tomcat, or use tomcat8 or above directly

.
