Spring Boot REST Controller returns 404 when deployed on external tomcat 9 server
I have a spring boot rest web application which works perfectly on the embedded server. However after following the steps mentioned in the is blog https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file, I got a 404 error message whan I send a resquest to a resource on the server.I have used java 1.8.0_212 locally and used java 1.8.0_131 and deployed my app on tomcat 9 on the server. One thing that's puzzling me is that the repositories which extends CrudRepository can be accessed. Below is my application's entry point.
@SpringBootApplication
@ComponentScan(basePackages = "com.dbe.ref")
public class RefmsApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(RefmsApplication.class);
}
public static void main(String[] args) {
SpringApplication.run(RefmsApplication.class, args);
}
and also my pom.xml

Answer
There is a little difference when you deploy application on embedded server and external server by default.
With embedded server you can access you application by using:
http://localhost:<port>/<resourceName>
While if you deploy war in another container then you need to add application name with version like:
http://localhost:<port>/<applicationNameWithVersion>/<resourceName>
For example if you deploy this example then URL for embedded server is:
http://localhost:8080/greeting
And URL for Externally deployed application if like:
http://localhost:8999/gs-rest-service-0.1.0/greeting
Note: This URL is of my application server so it may have some changes for yours.
