Spring Boot vs. JAX-RS (Restlet) for dead simple microservice
<p>I want to build a really small self-contained microservices serving some REST operations storing the data in memory (no persistence required).</p>

<p>Hence, I am looking framework-wise for the most lightweight approach. After looking into an available JAX-RS implementations Restlet seemed to be a good choice.</p>

<p>Also got Spring Boot recommended with the comment you don't need JAX-RS. I got a bit confused. Isn't JAX-RS the standard for Java REST applications? Wouldn't I need to combine Spring Boot with JAX-RS anyway?</p>
