Jboss7 : Undertow Spring Boot throwing 404 - spring

Question

I'm developing a Spring boot application.
I'm building a war file for JBoss
My war is building correctly , I'm using *-war.original as deployment for JBoss
the deployment seems fine
But when I make call to controller, it's throwing a 404
With embedded sever it's working fine

Getting "404 - Not found" error with Wildfly and springboot

Answer 1

Finally figured out what was wrong in I did, I have an Application class with main method without #SpringBootApplication along with SpringBootServletInitializer , So Jboss was not picking up the mapping correctly
The resolution was to make SpringBootServletInitializer class with main method. So I change ServletInitializermentioned in question
#SpringBootApplication
public class ServletInitializer extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(ServletInitializer.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(ServletInitializer.class);
}
#Override
public void onStartup(ServletContext servletContext) throws ServletException{
super.onStartup(servletContext);
}
}
After that I was able to hit endpoint,
Why I didn't do this earlier ??
I generated the project using
SPRING INITIALIZR with war packaging, When SPRING INITIALIZR generate project Application and SpringBootServletInitializer classes was there.
Among both classes Appliaction class has the main method and #SpringBootApplication annotation
While writing Integration test initially it was not working , Then I change #SpringBootApplication annotation to SpringBootServletInitializer and write a main method in SpringBootServletInitializer test start working. But I kept the main method back in Appliaction class that was the root cause of this issue.
Since Spring Initializer, generate the classes I was in assumption , all classes generated are required to build war .So I kept the Application class the way it's generated without #SpringBootApplication annotation while generating war file. I think Jboss got confused which main method it should run. And eventually throwing a 404 exception while hitting end point
