title: Spring Boot full REST CRUD example
body: <p>Does anyone have a full spring boot REST CRUD example? The spring.io site just has a RequestMapping for GET. I'm able to get POST and DELETE working but not PUT. </p>
  
  <p>I suspect it's how I'm trying to get the params where the disconnect is, but I have not seen an example where someone is performing an update. </p>
  
  <p>I'm currently using the SO iPhone app so I can't paste my current code. Any working examples would be great!</p>
