Spring -Hateoas Client using Traverson

I want to use my Spring-Hateoas rest service from Traverson, but I came up with the next question: I didn't find anything on the internet. I am using Spring-Boot 1.1.10.RELEASE .

My client call looks like this:

... 

final Traverson traverson = new Traverson(new URI("http://localhost:8080/bbsng-app-rest"), MediaTypes.HAL_JSON);

...

      

        
        
        
      

    

And I am getting the following problem:

java.lang.NoClassDefFoundError: Could not initialize class org.springframework.hateoas.client.Traverson
at at.compax.bbsng.client.mvc.client.service.BerufServiceImpl.findeAlleBerufe(BerufServiceImpl.java:41)
