Run Spring Boot application in Standalone Tomcat Server

How to run Spring Boot application on Tomcat

To deploy a Spring Boot application on existing Tomcat Server, or to bundle it as war file and deploy on Tomcat, following changes are required:

• Change to war packaging in pom.xml:

<packaging>war

• Application Main class to extend  SpringBootServletInitializer.
• Override configure method in this class.

               protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

                       return application.sources(Application.class);

               }

• Add Tomcat-starter dependency in pom.xml.

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-tomcat</artifactId>

    <scope>provided</scope>

</dependency>

• Run maven install, war will generate in target folder.
• Deploy on standalone Tomcat Server.
• Don't forget to add context root to access the services.
