(possibly) resolved `or at least it looks like. I am not quite sure where this is the problem. Surely the configuration proposed by Biju Kunjummen works and seems cleaner to me. What I am doing now so as not to create a mess is to work only inside Eclipse, sometimes cleaning projects and never using maven to package and deploy it (at least in everyday programming, I think with some reliable maven script or CI Server everything will work fine).
I am trying to configure the Rest API using Spring MVC. I read a lot of documentation, but I still get the error in the topic:
No mapping for HTTP request with URI [/ ecommerce-api / rest / checkout] in DispatcherServlet
The problem is exactly the same as reported (and resolved) in other similar issues, like this FIXED: "No mapping found" Attempt to configure the RESTfull interface using Spring -MVC
It is really strange that without changing anything in my code, once this works, and sometimes not. I am almost sure that nothing changes between these two points, because, for example, once I’m physically away, then I return and stop working.
At this specific moment, my code is as follows:

A fragment of the application server log file (VFabric, but I also tried with Tomcat 7) when I try to GET ecommerce-api / rest / checkout:

I really don’t know what to do, since it worked the last time I closed my Mac, and until that moment it seemed to me that I knew how to do it.
