title: Getting "No message available" error with Spring Boot + REST application
body: <p>I have created demo Spring Boot project and implemented Restful services as shown here </p>
  
  <pre><code>@RestController
  public class GreetingsController {
      @RequestMapping(value="/api/greetings", method=RequestMethod.GET, produces=MediaType.APPLICATION_JSON_VALUE)
      public ResponseEntity&lt;String&gt; getGreetings(){
          return new ResponseEntity&lt;String&gt;("Hello World", HttpStatus.OK);
      }
  }
  </code></pre>
  
  <p>When I tried to invoke the service with Postman tool with url "<a href="http://localhost:8080/api/greetings" rel="noreferrer">http://localhost:8080/api/greetings</a>" as request method GET, I am getting below error message</p>
  
  <pre><code>{
    "timestamp": 1449495844177,
    "status": 404,
    "error": "Not Found",
    "message": "No message available",
    "path": "/api/greetings"
  }
  </code></pre>
  
  <p>Per Spring Boot application, I don't have to configure the Spring Dispatcher servlet in web.xml.</p>
  
  <p>Can someone help me to find out the missing point here? </p>
