On the other hand, PUT, POST, and DELETE are unsafe, because they modify the resource on the server. Some of the HTTP operations, which doesn't modify the resource at the server, are known as safe operations, including GET and HEAD. REST API uses HTTP methods to perform operations. By exposing entities as the resource, it allows a client to read, write, modify, and create resources using HTTP methods, for example, GET, POST, PUT, DELETE, etc. However, if you are not familiar with REST, I suggest you to first check out the REST API design and development to better understand it.Ī resource is how data is represented in the REST architecture. a book in the server can be delivered to the client using JSON or XML. REST stands for the REpresentational State Transfer, which uses the HTTP protocol to send data from the client to the server, e.g. Here are a couple of frequently asked questions about using REST web services in the Spring Framework. 20 Spring REST Web Service Interview Questions Since you cannot make life a non-trivial REST API without security, a good knowledge of security basics, HTTP basic authentication, digest authentication, OAuth, and JWT is very important. which can make your Controller REST more aware, so that you don't need to do common stuff required by every single REST API, like converting the response to JSON.Ī good knowledge of Spring Security is also mandatory for developing security for RESTful web services in the real world. Spring also provides customized annotations for RESTful Web Services, e.g. The HTTPMessageConverter can convert your HTTP response to JSON or XML just by detecting a relevant library in the classpath, e.g. But, if the job description mentions REST and web services, you also need to be aware of how to develop RESTful web services using the Spring Framework.įrom Spring 3.1, the framework has been enhanced a lot to support many features needed for the RESTFul API. Since the Spring Framework is the most popular and standard framework for developing Java web applications and RESTful web services, a good knowledge of Spring core and Spring MVC is expected from any senior Java developer. Hopefully this post gave you a bit more background so you can do your own comparison.Hello guys! I have been sharing some REST with Spring tutorials from the last a couple of months, and today, I am going to share some of the frequently asked Spring MVC and REST interview questions for Java devs applying for web developer roles. Dropwizard (which uses an embedded Jetty container and Jersey) is probably the closest thing to a Spring Boot app. Now, comparing a Spring Boot application and an WAR packaged application, isn’t exactly comparing apples to apples. I hacked up a Thymeleaf view for Jersey once, but I think Spring MVC takes the cake here. Rendering pages server side is not part of the JAX-RS spec (though it is supported with extensions). If you’re creating an object JSON / XML REST layer, JAX-RS resources backed by the DI framework of your choice (Spring, Guice, etc.) might be the way to go. If you’re already a Spring shop, just use Spring. JAX-RS = Should You Use JAX-RS over Spring Rest? This is not an exhaustive list, but it does include the most common annotations. ![]() ![]() To help you navigate between the world of Spring and JAX-RS here is a quick cheat sheet. All that is left, is to instruct Jersey to scan the resources package again, the rest is handled for you (see what I did there?!).įrom the spring-jaxrs directory, this example can be started with the same mvn spring-boot:run command. ![]() First, you probably noticed the annotation which is used to mark this class managed by Spring. This class is a bit slimmer than the previous example. ( "/troopers" ) public class StormtrooperController
