Spring 5.0 Cookbook

Overview of this book

The Spring framework has been the go-to framework for Java developers for quite some time. It enhances modularity, provides more readable code, and enables the developer to focus on developing the application while the underlying framework takes care of transaction APIs, remote APIs, JMX APIs, and JMS APIs. The upcoming version of the Spring Framework has a lot to offer, above and beyond the platform upgrade to Java 9, and this book will show you all you need to know to overcome common to advanced problems you might face. Each recipe will showcase some old and new issues and solutions, right from configuring Spring 5.0 container to testing its components. Most importantly, the book will highlight concurrent processes, asynchronous MVC and reactive programming using Reactor Core APIs. Aside from the core components, this book will also include integration of third-party technologies that are mostly needed in building enterprise applications. By the end of the book, the reader will not only be well versed with the essential concepts of Spring, but will also have mastered its latest features in a solution-oriented manner.

Preface

Creating @Scheduled services


Spring 5 still supports batch processes or service transactions whose executions are triggered by time, just like any timer-based applications. The following recipe highlights the creation of batched transactions that run inside the Spring MVC container.

Getting started

Open a project, ch08, and add the following time-driven @Service methods.

How to do it...

Scheduled services are usually used to implement batch processing that can run simultaneously with the request handlers. To create these types of services, follow these steps:

  1. To enable schedule-based transactions, create a context definition SpringScheduledConfig which implements org.springframework.scheduling.annotation.SchedulingConfigurer. Apply the class-level annotation @EnableScheduling and override the method configureTasks() with the preferred configurations of org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler injected in it:
@Configuration 
@EnableScheduling 
public class SpringScheduledConfig...
