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
    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

What am I missing here ?


The spring boot entry point class:

public class App extends SpringBootServletInitializer {
public static void main(String[] args) {, args);

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

public String demo() {
return "Helloo.. !!";

Spring boot version => v1.3.2.RELEASE

The logs when I deploy to tcServer

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


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.
