1. Replace the @Controller annotation for TestController with @RestController, and remove @ResponseBody from the ping method.

2. In TestController, create a method named echo that's mapped to "echo" using the POST method. It should take a String parameter annotated with @RequestBody. It should return the parameter passed.

3. Test this endpoint using Postman. Add a new request tab. Select POST as the method and http://localhost:8080/echo as the URL. Under the request, click Body, and choose raw. Enter a message like "Hello, REST!" and send the request.
