Cannot deploy a spring boot app on tomcat - spring-boot

Question

My spring boot app works fine and correctly when I access it locally localhost:8080.
When I deploy it on Apache Tomcat/7.0.76 I get the following error:
FAIL - Application at context path /attributes could not be started
FAIL - Encountered exception org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/attributes]]
I followed the instructions here and read many SO questions similar to mine but cannot find the solution.

xxxLinkingserviceApplication.app
#SpringBootApplication
public class xxxLinkingserviceApplication extends SpringBootServletInitializer {
/**
* Used when run as WAR
*/
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(xxxLinkingserviceApplication.class);
}
/**
* Used when run as JAR
*/
public static void main(String[] args) {
SpringApplication.run(xxxLinkingserviceApplication.class, args);
}
}
I build the war using mvn clean install and rename the xxx-linkingservice-0.0.1-SNAPSHOT.war to attributes.war and deploy it to Apache Tomcat/7.0.76. Tomcat installs it under /attributes but fails to start it.
Not sure if this is important but the java version on the machine where I build the .war is:
openjdk version "1.8.0_275"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_275-b01)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.275-b01, mixed mode)
while the tomcat runs using:
Java 1.8.0_302-b08 Red Hat, Inc.
Update:
I tried to create a new war with a "vanilla" spring boot application following this article and received the same error when starting the app on tomcat.

I followed #Joachim Rohde answer and added the servlet-api dependency to my pom.xml.
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
</dependency>
From what I understand Tomcat 7 comes with tomcat-servlet-3.0-api.jar. The HttpSessionIdListener class come according to this documentation in version 3.1.
This is still not fixing my problem and I still get the following error:
Sep 10, 2021 1:12:51 PM org.apache.catalina.startup.HostConfig deployWAR
SEVERE: Error deploying web application archive /vol/data/tomcat/webapps/web-services.war

Answer 1

The solution in my case was the spring-boot-starter-version in pom.xml. This one had to be 2.3.12.RELEASE (https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-parent).
