Reactive Java Microservices with Spring Boot and JHipster - Spring I/O 2022Matt Raible
Microservice architectures are all the rage in JavaLand. They allow teams to develop services independently and deploy autonomously.
Why microservices?
IF
you are developing a large/complex application
AND
you need to deliver it rapidly, frequently, and reliably over a long period of time
THEN
the Microservice Architecture is often a good choice.
Reactive architectures are becoming increasingly popular for organizations that need to do more, with less hardware. Reactive programming allows you to build systems that are resilient to high load.
In this session, I'll show you how to use JHipster to create a reactive microservices architecture with Spring Boot, Spring Cloud, Keycloak, and run it all in Docker. You will leave with the know-how to create your own resilient apps!

Spring Boot is a framework for creating stand-alone, production-grade Spring based applications that can be "just run". It aims to provide a radically faster and widely accessible starting experience for developing Spring applications. Spring Boot applications can be started using java -jar or traditional WAR deployments and require very little Spring configuration. The document then discusses system requirements, development environment, creating a simple Hello World application, using Spring Boot Admin to monitor applications, configuring databases, Spring Data JPA, REST controllers, caching with EhCache, building web applications with Thymeleaf, and project structure.
Maven is a build tool that can manage a project's build process, dependencies, documentation and reporting. It uses a Project Object Model (POM) file to store build configuration and metadata. Maven has advantages over Ant like built-in functionality for common tasks, cross-project reuse, and support for conditional logic. It works by defining the project with a POM file then running goals bound to default phases like compile, test, package to build the project.
This document summarizes different types of tests for Spring Boot applications, including unit tests, integration tests, and sliced tests. It discusses tools for mocking dependencies like MockRestServiceServer, Testcontainers for integration with Docker, and annotations like @MockBean and @SpyBean. Context caching, properties, and dirty context handling are also covered. The document concludes with an upcoming talk on JUnit 5.

Functional Thinking - Programming with Lambdas in Java 8Ganesh Samarthyam
Functional programming is on the rise. Almost all major and mainstream languages support functional programming features, including C++, Java, Swift, and Python, and Visual Basic. With Java 8’s lambda functions, Java now supports functional programming. Moving to functional programming can result in significantly better code and productivity gains. However, it requires a paradigm shift: you need to move away from imperative and object-oriented thinking to start thinking functionally. That’s what this workshop will help you achieve: it will help you make your shift towards functional programming. The workshop will introduce lambda functions in Java with examples from Java library itself. Presented in OSI Days 2015 workshop - http://osidays.com/osidays/shifting-to-functional-programming-lambdas-for-java-developers/
Let us explore Java 8 features and start using it in your day to day work. You will be surprised how Java has evolved to become so different yet easy & powerful. In this presentation, we discuss Java 8 Stream API.
Supercharged java 8 : with cyclops-reactJohn McClean
Overview of the rationale behind cyclops-react and some of it's features, including extended Java Collections, more powerful Sequential and Parallel Streaming, pattern matching, data types (such as Xor cyclops-react Either type, Maybe, Eval).
The document discusses new features in Java 8 including lambda expressions, default methods in interfaces, streams API and functional interfaces. Lambda expressions allow representing anonymous functions and can be used to filter, map and process collections. Default methods allow adding new methods to interfaces without breaking existing implementations. Streams API provides a way to process data pipelines in a declarative way and supports parallel and sequential operations on collections.

Project Lambda: Functional Programming Constructs in Java - Simon Ritter (Ora...jaxLondonConference
Presented at JAX London 2013
The big language features for Java SE 8 are lambda expressions (closures) and default methods (formerly called defender methods or virtual extension methods). Adding lambda expressions to the language opens up a host of new expressive opportunities for applications and libraries. You might assume that lambda expressions are simply a more syntactically compact form of inner classes, but, in fact, the implementation of lambda expressions is substantially different and builds on the invokedynamic feature added in Java SE 7.
The document discusses new features in Java SE 8 including lambda expressions and streams. Lambda expressions allow for anonymous functions and functional programming techniques. Streams provide a way to perform aggregate operations on collections in a declarative way. Key points covered include how lambda expressions work, method references, default methods that allow interfaces to evolve, and examples of using streams to perform common collection operations like filtering, mapping, reducing and collecting results.
Functional Programming With Lambdas and Streams in JDK8IndicThreads
The significant new language feature in Java SE 8 is the introduction of Lambda expressions, a way of defining and using anonymous functions. On its own this provides a great way to simplify situations where we would typically use an inner class today. However, Java SE 8 also introduces a range of new classes in the standard libraries that are designed specifically to take advantage of Lambdas. These are primarily included in two new packages: java.util.stream and java.util.function.
After a brief discussion of the syntax and use of Lambda expressions this session will focus on how to use Streams to greatly simplify the way bulk and aggregate operations are handled in Java. We will look at examples of how a more functional approach can be taken in Java using sources, intermediate operations and terminators. We will also discuss how this can lead to improvements in performance for many operations through the lazy evaluation of Streams and how code can easily be made parallel by changing the way the Stream is created.

This document discusses functional programming concepts in Java 8, including lambda expressions, method references, and streams. Lambda expressions allow for anonymous functions and internal iteration. Method references provide shorthand syntax for referring to methods. Streams provide a way to perform aggregate operations on collections in a declarative way and can optimize processing through parallelization. Optional is a container class that helps eliminate null checks. Default methods allow interfaces to define behavior while maintaining backwards compatibility.
Improved Developer Productivity In JDK8Simon Ritter
The document discusses new features in Java SE 8 that improve developer productivity. It describes lambda expressions and method references that allow for more functional-style programming. It also covers streams, which provide a way to process collections of objects in a declarative way and support aggregate operations. Default methods are discussed as a means to evolve library APIs in a backwards compatible way.

Reactive Programming: A New Asynchronous Database Access API, a possible new Java standard for accessing SQL databases, where user threads never block! - presented by Kuassi Mensah
The document discusses the new features of Java EE 7 including WebSockets, JSON processing, batch applications, concurrency utilities, simplified JMS API, RESTful web services client API, and more annotated POJOs. It provides details on each of the top 10 features and how they improve developer productivity and meet enterprise demands. The document encourages developers to download the Java EE 7 SDK and GlassFish 4.0 implementation to use the new features.
The document discusses asynchronous database access (ADBA) in Java. ADBA aims to provide a non-blocking API for database access that is complementary to the standard JDBC API. It uses CompletionStage and CompletableFuture from the Java class library to support asynchronous programming. The key concepts discussed include execution model, connection handling, operations, operation groups and transactions. Code examples demonstrate basic usage of the proposed ADBA API.
This document provides an overview of Java 8 including:
- Java 8 has approximately 9 million developers and Oracle supports versions 6-8.
- New features include default methods, lambda expressions, streams, and parallel processing capabilities.
- JavaScript integration allows JavaScript code to be run from Java, enabling database and other connections from JavaScript.
- Potential issues with Java 8 include more complex debugging due to lambda expressions and increased abstraction.
The document discusses the benefits of moving JIT compilation out of individual JVMs and into a shared, cloud-based compiler service. This "JIT-as-a-Service" approach improves efficiency by allowing optimization resources to be shared and elastic across JVMs. It also enables optimized code to be reused for applications that execute on multiple devices. Moving JIT compilation to the cloud reduces warmup time, memory footprint, and CPU usage for JVMs while improving the level of optimizations that can be performed.
The Java Virtual Machine (JVM) can deliver significantly better performance through the use of Just In Time compilation. However, each time you start an application it needs to repeat the same process of analysis and compilation. This session discusses Java with Co-ordinated Checkpoint at Restore. This is a way to freeze an application and start it again (potentially many times) from the same checkpoint.
This session, delivered at Devoxx Poland, covers all the major changes to the Java platform between JDK 12 and JDK 17. All language features are covered, as well as many of the important API changes.
How to monitor Java application and JVM performance with Flight Recorder and Mission Control. Starts with a discussion of general JVM performance considerations like GC, JIT and threads.
This document summarizes new features being added to Java in recent and upcoming versions. It discusses switch expressions, text blocks, records, sealed classes, and pattern matching instanceof, which have been added or previewed in JDK 12-16. The document emphasizes that the six-month release cycle is allowing Java to deliver new features to developers more quickly while using preview features and modules to gather feedback before finalizing changes. It encourages developers to try new Java versions and previews from Azul Systems to experience these improvements to the language.

There are now several providers of builds of OpenJDK. In this presentation, we look at what aspects of a JDK distribution you should consider when making a choice.
This document provides an overview of Java programming concepts including:
- Java language syntax such as variables, data types, operators, and control structures
- Object-oriented programming concepts like classes, objects, inheritance, and polymorphism
- GUI programming basics using the Abstract Window Toolkit (AWT) including components, layout managers, events, and menus
- Key classes and interfaces like Object, Class, and interfaces
There have been a number of changes to the way the JDK is developed, distributed and updated. In this session, we look at what those changes are and how they impact developers.
This document discusses Java releases from JDK 9 through JDK 12. Some key points:
- JDK 9 introduced modules and removed deprecated APIs. JDK 10 added local variable type inference.
- Starting with JDK 11, Oracle OpenJDK binaries are only supported for 6 months until the next release.
- JDK 12 may include switch expressions, Shenandoah GC, and new Collectors and Class APIs.
- Long term, Project Amber aims to simplify syntax and Project Valhalla will introduce value types.
The pace of development of the JDK has changed to a new release every six months. Find out what's new and what the long-term plans are for the most popular development platform on the planet.
Many people are unsure about what recent changes to the release cadence of the JDK as well as the availability of different binaries and updates means. This session seeks to explain all you need to know.
