Setting Up Swagger 2 with a Spring REST API. 1.

Setting Up Swagger 2 with a Spring REST API

Overview When creating a REST API, good documentation is instrumental. Moreover, every change in the API should be simultaneously described in the reference documentation. Accomplishing this manually is a tedious exercise, so automation of the process was inevitable. GitHub - livelessons-spring/building-microservices: Building Microservices with Spring Boot. How Spring Boot Autoconfiguration Magic Works.

Spring Boot with Docker. Now you can create a simple application. src/main/java/hello/Application.java package hello; import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.bind.RelaxedPropertyResolver;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController; @SpringBootApplication@RestControllerpublic class Application { @RequestMapping("/") public String home() { return "Hello Docker World"; } public static void main(String[] args) { SpringApplication.run(Application.class, args); } } The class is flagged as a @SpringBootApplication and as a @RestController, meaning it’s ready for use by Spring MVC to handle web requests.

Spring Boot with Docker

Centralized Configuration. You’ll first need a Config Service ( configuration-service) to act as a sort of intermediary between your Spring applications and a typically version-controlled repository of configuration files.

Centralized Configuration

You can use Spring Cloud’s @EnableConfigServer to standup a config server that other applications can talk to. This is a regular Spring Boot application with one annotation added to enable the config server. configuration-service/src/main/java/hello/ConfigServiceApplication.java package hello; import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.config.server.EnableConfigServer; @EnableConfigServer@SpringBootApplicationpublic class ConfigServiceApplication { public static void main(String[] args) { SpringApplication.run(ConfigServiceApplication.class, args); }}

OmniGraffle - diagramming and graphic design for Mac, iPhone, and iPad. Async systems with sync clients. As the Reactive Manifesto says Reactive systems are: Responsive Resilient Elastic Message Driven The last principle often goes together with non-blocking async protocols.

Async systems with sync clients

This style of communication "allows recipients to only consume resources while staying active, leading to less system overhead". This fits perfectly with new demands of efficiency derived from the elastic model of cloud providers. Reactive Programming in the Netflix API with RxJava. By Ben Christensen and Jafar Husain Our recent post on optimizing the Netflix API introduced how our web service endpoints are implemented using a reactive programming model for composition of asynchronous callbacks from our service layer.

Reactive Programming in the Netflix API with RxJava

This post takes a closer look at how and why we use the reactive model and introduces our open source project RxJava – a Java implementation of Rx (Reactive Extensions). Reactive Programming in the Netflix API with RxJava. What Architects Should Know About Reactive Design Patterns. It is widely understood that our software needs to become reactive; we need to consider responsiveness, maintainability, elasticity and scalability from the outset.

What Architects Should Know About Reactive Design Patterns

Not all systems need to implement all these to the same degree, as specific project requirements will determine where effort is most wisely spent. But, in the vast majority of cases, the need to go reactive will demand that we design our applications differently. Modern applications present incredible design challenges: we expect near-realtime performance while managing petabyte-scale data and distribution across environments ranging from traditional servers to cloud systems to mobile devices.

Developing Reactive Microservices: free O'Reilly mini-book by Java Champion Markus Eisele. As we continue to help organizations modernize their legacy systems with Microservices architecture, our latest mini-book arrives right on time.

We are happy to announce the availability of Developing Reactive Microservices: Enterprise Implementation in Java, a new O'Reilly mini-book authored by Java Champion and Lightbend Developer Advocate, Markus Eisele (@myfear). Download a free copy in PDF, EPUB or MOBI format (or all three!) With microservices taking the software industry by storm, traditional enterprises running large, monolithic Java EE applications have been forced to rethink what they’ve been doing for nearly two decades. Next Generation Session Management with Spring Session. Session management has been part of enterprise Java for so long that it has faded to the background of our consciousness as a solved problem, and we have not seen any major innovation in that arena in recent memory.

However the modern trend towards micro services and horizontally scalable cloud native applications challenges the assumptions upon which session managers have been designed and built for the past 20 years, and exposes flaws in the design of modern session managers. This article will demonstrate how the recently released Spring Session APIs help surmount some of the limitations of the current approach to session management, traditionally employed by enterprise Java. We will start with a summary of the problems with current session managers, then dig into the details of how Spring Session solves each of those problems.

A Journey into Microservices: A Cloudy Beginning

Start reading at part one, A Journey into Microservices. From the start there were a number of guiding principles we wanted to instill into our new platform. One of these was taking a Cloud Native approach, something which had been been pioneered by Netflix. Adrian Cockcroft has talked about the approach Netflix took, with their aim during this process being to: “Construct a highly agile and highly available service from ephemeral and assumed broken components” –Adrian Cockcroft. Dystopia as a Service. Microservices with Spring. Functional Reactive in the Netflix API with RxJava. Creating an Asynchronous, Event-Driven Application with Reactor. Reactor - a foundation for asynchronous applications on the JVM. We’re pleased to announce that, after a long period of internal incubation, we’re releasing a foundational framework for asynchronous applications on the JVM which we’re calling Reactor.

It provides abstractions for Java, Groovy and other JVM languages to make building event and data-driven applications easier. Why REST Keeps Me Up At Night. This guest post comes from Daniel Jacobson (@daniel_jacobson), director of engineering for the Netflix API. Prior to Netflix, Daniel ran application development for NPR where he created the NPR API, among other things. He is also the co-author of APIs: A Strategy Guide and a frequent contributor to ProgrammableWeb and the Netflix Tech Blog. With respect to Web APIs, the industry has clearly and emphatically landed on REST as the standard way to implement these services. Time to Move to a Four-Tier Application Architecture.

The new year is well underway and, like many others, you are probably planning upcoming projects to enhance your existing digital experiences or build completely new websites and applications. As you do so, the most critical fact to keep in mind is that “web” no longer means “web browser.” Pundits have been espousing a “mobile first approach” to application development for years, but with an annual mobile traffic growth rate of nearly 60% this is not negotiable any longer. The explosion in the number of connected devices, the shift of traffic from desktop to mobile, and the rising tide of the internet of things means that projects must now be rooted in the diversity of user experiences available on different devices.

To build and deploy apps that effectively attract and retain customers on a range of devices, you need to embrace a new way of thinking about app design. Why is the Standard for Application Architecture Changing? Immutable Infrastructure: what is it? - HighOps.
