I have a SpringBoot application that I am trying to deploy to Tomcat Server. According to references online, I have added some code in the Application class as follows:
public class SkyVetApplication extends SpringBootServletInitializer{ ... @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(SkyVetApplication.class); } ... } In build.gradle I have added the following:
compile group: 'org.springframework.boot', name: 'spring-boot-starter-web' **providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'** After doing a clean build I have copied the war file to Tomcat's webapps folder. But the deployment happens twice and ends with an exception as context is already present. What am I missing?
Help is very much appreciated.

You should add a main method.
Check out these examples: https://github.com/Pytry/bootiful-war-deployment
Here's an example from the "hello" module (it's using Lombok annotation processors).
package com.example.bootifulwar; import lombok.extern.slf4j.Slf4j; import org.springframework.beans.factory.annotation.Value; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.support.SpringBootServletInitializer; import org.springframework.scheduling.annotation.EnableScheduling; import org.springframework.scheduling.annotation.Scheduled; @SpringBootApplication @EnableScheduling @Slf4j public class HelloServletInitializer extends SpringBootServletInitializer{ @Value("${messageForUser}") private String message; @Value("${whatDoesTheFoxSay:'No body knows.'}") private String whatDoesTheFoxSay; public static void main(String[] args){ SpringApplication.run(HelloServletInitializer.class, args); } @Scheduled(fixedRate = 2000) public void sayHelloTo(){ log.info("Hello! " + message); } @Override public SpringApplicationBuilder configure(SpringApplicationBuilder application){ log.info( "\n*********************\n" + "What does the fox say?\n" + whatDoesTheFoxSay + "\n*********************\n"); return application.sources(HelloServletInitializer.class); } } To take advantage of individualized logging and external "application.properties", assuming you deploy more than one war file to the same Tomcat, you will need to place a custom context.xml for each applications context-path inside of "conf/Catalina/localhost.".
Example:
<?xml version='1.0' encoding='utf-8'?> <Context docBase="hello.war" path="hello"> <Resources className="org.apache.catalina.webresources.StandardRoot"> <PreResources base="hello\\config" className="org.apache.catalina.webresources.DirResourceSet" internalPath="/" webAppMount="/WEB-INF/classes"/> </Resources> </Context> I'm not an expert at gradlem but your dependencies look fine.
Hope that helps.
