title: How to make concurrent rest requests
body: <p>Hi I am trying to write an integration test which will make concurrent (say 3 concurrent for example) restful api calls, and I need to assert the data returned in each call is different.  This is because I have a find and update and return data within a synchronized block,so I need to test the data returned is different for each thread.  I have looked at the junit activetestsuite but unsure how to apply this to my integration test. API call i want to make in my IT test is below</p>
  
  <pre><code>  ResponseEntity&lt;String&gt; response = this.restTemplate
                  .exchange("endpoint/",HttpMethod.GET,String.class);
  
   //make assertions on each returned call
  </code></pre>
