REST has directly buy the farm a touchstone way to prepare spider web services as well as when it comes to Java, in that place are many frameworks as well as library available e.g. JAX-RS, Restlet, Jersey, RESTEasy, Apache CFX etc, only I encourage Java developers to purpose Spring framework to prepare RESTful spider web services. But, closed to of you lot mightiness ask, why purpose Spring Framework to prepare RESTful spider web services inwards Java? What is the wages as well as why it's amend than other frameworks as well as libraries available out there? Well, the most of import argue I think to purpose Spring for developing RESTful spider web service is that you lot tin purpose your Spring MVC sense to prepare RESTful spider web services.
This is 1 of the biggest wages i.e. leveraging your years of sense on Spring MVC to break your application equally REST APIs. Another argue is that Spring has fantabulous back upwards for developing RESTful spider web services.
In final a distich of versions, starting from Spring version 3.0, it has provided a lot of enhancements to Spring MVC to render first-class REST support. It has provided dedicated annotations e.g. @RestController and @ResponseStatus to brand the evolution of RESTful resources fifty-fifty easier inwards Spring 4.0.
It's too non exclusively assist you lot to create RESTful spider web services only too provides classes to eat REST resources e.g. you lot tin purpose RestTemplate bird to eat RESTful resources.
There are many to a greater extent than utility classes as well as annotations which makes the evolution of RESTful spider web services inwards Spring easier as well as seamless as well as I'll portion a distich of them inwards this article to evidence my betoken that using Spring to prepare RESTful Web service is the right decision.
1. In Spring MVC, a controller tin grip requests for all HTTP methods, which is a backbone of RESTful spider web services. For example, you lot tin grip GET method to perform read operation, POST method to create resources, PUT method to update resources, as well as DELETE method to take away resources from the server. From Spring 3.2 onwards, you lot tin too grip PATCH requests. Btw, if you lot are non familiar alongside Spring MVC framework then Spring MVC For Beginners on Udemy is a proficient house to start.
2. In instance of REST, the representation of information is real of import as well as that's why Spring MVC allows you lot to bypass View-based rendering altogether past times using the @ResponseBody annotation as well as diverse HttpMessgeConverter implementations.
By using this ii you lot tin conduct shipping a reply to customer e.g. the resources clients wants as well as too inwards the format they want.
I'll write to a greater extent than nearly @ResponseBody annotations as well as HttpMessageConverter inwards this spider web log inwards coming articles, only if you lot can't wait, I advise you lot buy the farm through REST alongside Spring Certification class by Eugen. He non exclusively explains the basic details of developing RESTful spider web services only too advanced details similar versioning as well as securing your REST APIs using Spring Security.
3. The Spring 4.0 liberate added a dedicated annotation @RestController to brand the evolution of RESTful spider web services fifty-fifty easier.
If you lot annotate your controller bird using @RestController instead of @Controller as well as thus Spring applied message conversations to all handler methods inwards the controller.
This agency you lot don't demand to annotate each method alongside the @ResponseBody annotation. This too makes your code much cleaner. You tin read to a greater extent than nearly it on my post difference betwixt @Conroller as well as @RestController inwards Spring.
4. One of the primary departure betwixt REST spider web services as well as a normal spider web application is that REST overstep resources identifier information inwards URI itself e.g. /messages/101 spell spider web application unremarkably uses a query parameter e.g. /messages?Id=101.
If you lot remember, nosotros purpose @RequestParam to acquire the value of those query parameter only non to worry, Spring MVC too provides a @PathVariable annotation which tin extract information from URL. It allows the controller to grip requests for parameterized URLs.
You tin larn to a greater extent than nearly @PathVariable inwards my post difference betwixt @RequestParam as well as @PathVaraible inwards Spring.
5. Another key appear of RESTful spider web services is Representation e.g. the same resources tin live on represented inwards dissimilar formats e.g. JSON, XML, HTML etc. Thankfully Spring provides several thought implementations as well as views resolvers to homecoming information equally JSON, XML, as well as HTML.
For example, ContentNegotiatingViewResolver tin expect at the file extension of requests or Accept header to notice out the right representation of a resources for the client.
6. Similar to @ResponseBody annotation, which is used for converting the reply to the format customer wants (by using HttpMessageConverts), Spring MVC too provides @RequestBody annotation, which uses HTtpMethodConverter implementations to convert inbound HTTP information into Java objects passed into a controller's handler method.
You tin farther run across REST alongside Spring MasterClass to larn to a greater extent than nearly @RequestBody annotation as well as how to effectively purpose it to prepare RESTful spider web services inwards Java alongside Spring.
7. Spring Framework too provides a Template class, RestTemplate, similar to JdbcTemplate, as well as JmsTemplate, which tin eat REST resources. You tin purpose this bird to essay your RESTful spider web service or prepare REST clients.
I convey already talked nearly this bird inwards my before spider web log posts as well as you lot tin run across this tutorial for a alive illustration of using RestTemplate to eat JSON from a RESTful spider web service inwards Java.
These were closed to of the important features of Spring MVC framework which assistance inwards developing RESTful spider web services. As I told the most of import argue for me to select Spring for developing RESTful resources is that I tin purpose my existing cognition of framework, which agency no steep learning curve. If you lot expect at from high level, developing RESTful services is non real dissimilar from developing a spider web application.
The substitution departure is that inwards instance of former, nosotros generally bargain alongside human users where inwards instance of REST, you lot convey to bargain alongside non-human users generally rich JavaScript clients as well as mobile applications. This key departure as well as thus derives other differences e.g. representing information inwards JSON or XML instead of HTML which is suitable for human users only non for non-human systems.
If you lot are all the same non convinced, I advise you lot buy the farm through REST alongside Spring Certification class on Baeldung, belike the best resources on Spring alongside REST at the moment, which volition give you lot plenty argue to stick alongside Spring for developing both RESTful resources as well as REST clients.

How Spring Supports RESTful Web Services?
As I told you lot inwards the showtime paragraph that nosotros tin purpose Spring MVC to create as well as eat RESTful spider web services. Now, let's run across those supports inwards a fiddling flake to a greater extent than details thus that you lot tin brand the best purpose of them as well as rapidly prepare the RESTful services you lot e'er wanted to.1. In Spring MVC, a controller tin grip requests for all HTTP methods, which is a backbone of RESTful spider web services.
