title: Connection refused with rest assured junit test case
body: <p>The below test case gives me a connection refused exception and when i comment the method body it is success. So i believe there is no problem with ports but a problem with the rest assured invocation which i cant figure out. Even when i check with a rest client, the api it self successfully return books as json.</p>
  
  <pre><code>@Test
  public void testMe() {      
      get("/book").then().assertThat().contentType(ContentType.JSON);
  }
  </code></pre>
  
  <p>The controller looks like below,</p>
  
  <pre><code>@RestController
  @RequestMapping("/book")
  public class BookController {
  //Other crud api's are there
  
     @RequestMapping(method = RequestMethod.GET)
     public Map&lt;String, Object&gt; getAllBooks(){
     List&lt;Book&gt; books = bookRepository.findAll();
     Map&lt;String, Object&gt; response = new LinkedHashMap&lt;String, Object&gt;();
     response.put("totalBooks", books.size());
     response.put("books", books);
     return response;
     }    
  }
  </code></pre>
  
  <p>Exception trace,</p>
