GWT spring-boot application: servlet initialization - spring-boot

Question

I have a GWT application (gwt 2.8) on wich I want to add Spring-Boot dependency (1.5.3.RELEASE). I want a standalone executable war application
Here is my web.xml:
<?xml version="1.0" encoding="UTF-8"?>

}
I launch my application. It seems to start with no error. Nevertheless, in my web broser I have this error:

Why, in the logs, we see ServletDispatcher occurences? In my application should I define a ServletDispatcher? If it is the case, how to define my 5 web.xml servlets and filter to be taken into account?
What is curious, is that application runs and responds normally when I launch it from the GWT Development Mode (eclipse plugin).
Thank you
