In the post Exposing repositories as REST resources, we exposed a repository as a RESTful interface using Spring Data REST. However, that’s not the conventional way of creating REST API for Spring Boot Microservices. That particular approach works best if your data model is exactly similar to your domain model. Usually, that’s not the case. In this post, we will look at the right way of creating REST API using Spring Boot.
For any application, it is an important functionality to be able to provide its data to the consumer. REST APIs are one of the most popular ways to do so. In this post, we will look at the process of exposing repositories as REST resources using Spring Boot. REST or Representational State Transfer is an architectural style that advocates the use of standard HTTP protocol to expose such an interface. And by the way, Spring Boot makes it very easy to do so.
If you are familiar with modern web development then you will have encounter the terms like REST and API. If you have worked with APIs or heard of these terms but do not have complete understanding of how to build your own API or how they communicate and work, this tutorial RESTful web services – simple tutorial for beginners is for you. In this tutorial, I will be sharing what are REST and RESTful APIs, overview of REST principles, understanding the terms Request and Response, REST API Endpoints and at last conclusion.
Some cURL POST request examples for self reference: To POST without data, To POST with data, To POST with a file, add this -F file=@”path/to/data.txt” , To POST with JSON data, add this -H “Content-Type: application/json”
APIs often self-document information, such as their implementation and internal structure, which can be used as intelligence for a cyber-attack. Additional vulnerabilities, such as weak authentication, lack of encryption, business logic flaws and insecure endpoints make APIs vulnerable to the attacks outlined below: Man In The Middle (MITM), API injections (XSS and SQLi), Distributed denial of service (DDoS)
APIs are created in ways that redefine and stretch products, services, and organizations. In this article, we’ll dig a little deeper into API design principles and best practices. Also, we’ll provide some examples and, hopefully, by the end, you’ll be more confident with moving forward with your APIs.
Spring is a popular Java application framework for creating enterprise applications. Spring Boot is the next step in evolution of Spring framework. It helps create stand-alone, production-grade Spring based applications with minimal effort. It promotes using the convention over configuration principle over XML configurations. Spring Boot Jersey tutorial shows how to set up a simple RESTFul application with Jersey in a Spring Boot application. Jersey is an alternative to Spring RESTFul applications created with @RestController.
Learn to configure and create JAX-RS 2.0 REST APIs using Spring Boot and Jersey framework. This example application uses Jersey’s ServletContainer to deploy the REST APIs.
There is no best Java Rest framework. There is also no best Java microservice framework. Different frameworks serve different needs. For example, you might modify an existing application to expose the application’s API as Rest endpoints. Or, you might modify that application to consume somebody else’s REST endpoints. You might develop a new application or a standalone microservice. And you might even write a serverless function meant to reside in the cloud, for example, an Amazon Web Services (AWS) Lambda function. Diverse needs dictate different solutions. In this article, we compare several leading Java Rest frameworks. We then compare several leading microservice frameworks that use those REST frameworks.
