Pluralsight Building Asynchronous Restful Services With Jersey

How to Build Asynchronous RESTful Services with Jersey and Pluralsight

Asynchronous RESTful services are web services that can handle concurrent requests without blocking the server or the client. They are useful for scenarios where the response time is unpredictable or variable, such as fetching data from a remote database, processing complex calculations, or performing long-running tasks.

Jersey is a framework for developing RESTful web services in Java. It provides an easy-to-use annotation-based API that simplifies the creation and deployment of web resources. Jersey also supports asynchronous processing of requests and responses, using the standard Java concurrency API or third-party libraries such as RxJava or CompletableFuture.

Pluralsight is an online learning platform that offers courses on various topics related to software development, IT, and business. One of the courses available on Pluralsight is Building Asynchronous RESTful Services with Jersey, taught by Kevin Jones. This course covers the basics of asynchronous web services, the benefits and challenges of using them, and how to implement them using Jersey and different concurrency models.

In this article, we will give you an overview of what you will learn in this course and how it will help you improve your skills as a web developer.

What You Will Learn in This Course

The course consists of six modules, each covering a different aspect of asynchronous web services with Jersey. Here is a brief summary of what you will learn in each module:

Introduction: This module introduces the concept of asynchronous web services and explains why they are important for modern web applications. It also compares synchronous and asynchronous processing models and shows how to use JMeter to measure the performance of web services.

Asynchronous Processing in Jersey: This module shows how to use the @Suspended annotation and the AsyncResponse class to enable asynchronous processing of requests and responses in Jersey. It also demonstrates how to use callbacks, timeouts, and resume methods to control the flow of asynchronous operations.

Java Concurrency API: This module explores how to use the Java concurrency API to implement asynchronous web services with Jersey. It covers the ExecutorService interface, the Future interface, and the CompletableFuture class. It also explains how to handle exceptions and cancellation in asynchronous tasks.

RxJava: This module introduces RxJava, a library that provides a reactive programming model for asynchronous operations. It explains the concepts of observables, subscribers, operators, and schedulers. It also shows how to integrate RxJava with Jersey using the RxInvoker and RxObservableInvoker classes.

Reactive Streams: This module covers Reactive Streams, a standard for asynchronous stream processing. It explains the principles of backpressure, non-blocking I/O, and functional programming. It also shows how to use Jersey's support for Reactive Streams using the Flowable and Publisher classes.

Summary: This module summarizes the main points of the course and provides some tips and resources for further learning.

How This Course Will Help You Improve Your Skills

By taking this course, you will gain a solid understanding of how to build asynchronous RESTful services with Jersey and various concurrency models. You will learn how to:

Improve the scalability and performance of your web services by using non-blocking and concurrent techniques.

Leverage the power and flexibility of Jersey's annotation-based API to create and deploy web resources.

Use different concurrency models such as Java concurrency API, RxJava, and Reactive Streams to handle complex asynchronous operations.
