The great advantage of Spring Boot is that we can focus on the business rules avoiding some tedious development steps, boilerplate code, and a more complex configuration improving the development and easing the bootstrapping of new spring applications. dissertation where he proposed as its basis, six principles that should be separated between clients and servers the communication between client and server should be stateless multiple hierarchical layers can exist between them the server responses must be declared as cacheable or noncacheable the uniformity of their interfaces must be based in all interactions between client, server, and intermediary components and finally the clients can extend their functionality by using code on demand. REST stands for Representational State Transfer and it is an architectural style for designing distributed applications. The support for annotation starts from version 5 allowing different Java frameworks to adopt these resources.Īnnotation can also be used in REST API. This allows annotations to be retained by the Java virtual machine at run-time and read via reflection. Java annotations can also be embedded in and read from Java class files generated by the Java compiler. In the Java computer programming language, an annotation is a form of syntactic metadata that can be added to Java source code. At the same time, this can be achieved with a simple declarative annotation. ![]() By the standard programmatically process with a transaction template, this requires a more complex config and boilerplate code to write. As an example, we can refer to a transaction. The use of Java annotation gives developers the capability to reduce the code verbosity by a simple annotation. We at tutorialspoint wish you best luck to have a good interviewer and all the very best for your future endeavor.This post aims to demonstrate key Java used to build a functional Spring Boot Rest API. So just feel confident during your interview. Second it really doesn't matter much if you could not answer few questions but it matters that whatever you answered, you must have answered with confidence. If you are fresher then interviewer does not expect you will answer very complex questions, rather you have to make your basics concepts very strong. What is Next ?įurther you can go through your past assignments you have done with the subject and make sure you are able to speak confidently on them. It also provides supports for creating clients for RESTful web services. JAX-RS makes heavy use of annotations available from Java SE 5 to simplify development of JAVA based web services creation and deployment. JAX-RS is a JAVA based programming language API and specification to provide support for created RESTful Webservices. JAX-RS stands for JAVA API for RESTful Web Services. Throw generic Error Messages − A web service method should use HTTP error messages like 403 to show access forbidden etc. Validate Malformed XML/JSON − Check for well formed input passed to a web service method. GET method should not be able to delete data. Restriction on Method execution − Allow restricted use of methods like GET, POST, DELETE. No sensitive data in URL − Never use username, password or session token in URL, these values should be passed to Web Service via POST method. Session based authentication − Use session based authentication to authenticate a user whenever a request is made to a Web Service method. Protect your server against SQL or NoSQL injection attacks. Validation − Validate all inputs on the server. Following are the best practices to be followed while designing a RESTful web service − As RESTful web services work with HTTP URLs Paths so it is very important to safeguard a RESTful web service in the same manner as a website is be secured.
