One of the most mutual confusion with spider web developers is the alternative of PUT or POST HTTP method for creating or updating a resources piece developing RESTful Web Services. Since both tin live on used to submit data, y'all tin work either POST or PUT to create or update a resource. Many spider web developers desire to work PUT for creating a resources on the server because it's idempotent. No matter, how many times y'all telephone telephone the PUT, the dry reason of the resources volition non jeopardize. Since the possibility of re-submission is existent on a ho-hum network, using PUT to create resources makes it easy, equally y'all don't postulate to worry most user clicking the submit push multiple times. But, the fundamental indicate to shout out upward is that when y'all work PUT to create a resource, y'all postulate to furnish the id e.g.
Since most of the arrangement desire to expire on command of id i.e. they desire to generate id past times their ain inward the database, rather than customer specifying the id, PUT doesn't seem to live on the correct method to create a resource. It equally good poses the challenge of multiple clients creating a resources with the same id too instead of creating they terminate upward updating the resource.
Even though POST is non idempotent, it is a ameliorate alternative for creating resources because it doesn't require a user to furnish the id of the resource. Instead, when POST method completes it render the id too URI of the newly created resources inward the place header. Allowing the user to farther update the resources because it has both id too URI of the resource. See HTTP: The Definitive Guide past times David Gourley to larn to a greater extent than most idempotent too prophylactic methods of the HTTP protocol. One of the must read books for whatever spider web developers, including Java JEE programmers.
Similarly, PUT is the ameliorate alternative for updating resources because y'all already convey an id for the resources too its idempotent, thence fifty-fifty if the user submits multiple PUT asking the dry reason of the resources volition non live on compromised.
That's all most when to work PUT too POST HTTP methods inward RESTful spider web service. The brusk reply is, work POST to create a resources too work PUT to update the resource. It's non mandatory, only this seems to a greater extent than logical unless y'all tin foresee whatever effect which completely changes the opinion. If y'all desire to larn to a greater extent than most designing RESTful spider web service or desire to genuinely sympathise the philosophy behind REST thence see RESTful Web Services by Leonard Richardson, Sam Ruby, too David Heinemeier Hansson to larn to a greater extent than about

P.S. - If y'all are looking for online preparation to larn how to develop RESTful Web Services inward Java using Spring framework, I propose y'all joining Eugen Paraschiv's REST with Spring course. The class has diverse options depending upon your sense score too how much y'all desire to larn e.g. beginner's class, intermediate class, too principal class. You tin bring together the 1 which suits y'all better, though I propose joining the Master Class if y'all are serious most becoming an proficient Java REST developer.
