What is REST

I have created several sample applications to demonstrate different backend solutions for producing REST API.

In this post, I will create the REST API using JAXRS which is part of Java EE platform. On different application servers, the JAXRS implementation is different. Jersey is the official reference implementation which is shipped with Glassfish by default, and Resteasy is the JBoss alternative JAXRS implementation on JBoss platform(Jboss AS has been named to Wildfly).

REST API design and implementation

REST API design should embrace the HTTP verbs, for example.

URI	HTTP METHOD	REQUEST	RESPONSE/HTTP STATUS	DESCRIPTION
/posts	GET		200, [{'id':1, 'title':'my first post'}, {}]	Get all posts
/posts	POST	{ 'title':'my first post'}	201	Creat a post
/posts/{id}	GET		200, {'id':1, 'title':'my first post'}	Get post by id
/posts/{id}	PUT	{ 'title':'my first post'}	205	Update the post by id
/posts/{id}	DELETE		205	Delete the post by id
