How to deploy a spring boot web application on the embedded tomcat server, from the spring boot itself

Question

I have a spring boot project and I want to deploy the project on the embedded spring tomcat, since the server (suse-linux) does not have an application container. How can I do this? Is a .war or un.jar used for it? How do I configure the embedded tomcat to point to the java installed on the server ?.

.JAR

.WAR

Thanks for the help.

Answer 1

Providing the spring-boot-starter-web package with the correct configuration (maybe check the Basic guide from Spring Boot) your application will run in an embedded Tomcat application server. When building as a jar you should be able to run the application using java -jar on the SUSE machine. The embedded Tomcat should use the java installation from the process it was started by.
