REST call to spring boot RestController results 404 in tomcat but works in embedded tomcat

I am new to spring boot. I have knowledge on Spring mvc. I have developed small application with one @RestController as mentioned in Update below. This is working fine when I execute using

mvn spring-boot:run
(ie. embedded tomcat)


  1. The same REST call results in
    404 not found
    when I deploy as packaged war to tomcat. Target url
    http://localhost:8086/myapp/demo gives 404.

  2. I have the
    log4j2.xml
    created and when I execute with embedded tomcat it creates the expected log file, but with the external tomcat deployment it does not create the log file too and I do not find any logs in any of the tomcat logs under
    <tomcat-dir>/logs



What am I missing here ?

UPDATE:

The spring boot entry point class:

@SpringBootApplication
@RestController
public class App extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}

@Override
protected SpringApplicationBuilder configure(
SpringApplicationBuilder application) {
return application.sources(App.class);
}

@RequestMapping("/demo")
public String demo() {
return "Helloo.. !!";
}
}


Spring boot version => v1.3.2.RELEASE

The logs when I deploy to tcServer

UPDATE1:
I removed Angular, kept only spring boot @restcontroller. Problem still exists.

Answer

This was the problem with the target external Tomcat server that was pointing to JDK6, but my application was build using jdk7. Problem resolved once I point the external Tomcat to jdk7.
