Building Microservices with Spring

Overview of this book

Getting Started with Spring Microservices begins with an overview of the Spring Framework 5.0, its design patterns, and its guidelines that enable you to implement responsive microservices at scale. You will learn how to use GoF patterns in application design. You will understand the dependency injection pattern, which is the main principle behind the decoupling process of the Spring Framework and makes it easier to manage your code. Then, you will learn how to use proxy patterns in aspect-oriented programming and remoting. Moving on, you will understand the JDBC template patterns and their use in abstracting database access. After understanding the basics, you will move on to more advanced topics, such as reactive streams and concurrency. Written to the latest specifications of Spring that focuses on Reactive Programming, the Learning Path teaches you how to build modern, internet-scale Java applications in no time. Next, you will understand how Spring Boot is used to deploying serverless autonomous services by removing the need to have a heavyweight application server. You’ll also explore ways to deploy your microservices to Docker and managing them with Mesos. By the end of this Learning Path, you will have the clarity and confidence for implementing microservices using Spring Framework. This Learning Path includes content from the following Packt products: • Spring 5 Microservices by Rajesh R V • Spring 5 Design Patterns by Dinesh Rajput

Understanding cache abstraction

Basically, caching in Java applications is applied to the Java methods to reduce the number of executions for the same information available in the cache. That means, whenever these Java methods are invoked, the cache abstraction applies the cache behavior to these methods based on the given arguments. If the information for the given argument is already available in the cache, then it is returned without having to execute the target method. If the required information is not available in the cache, then the target method is executed, and the result is cached and returned to the caller. Cache abstraction also provides other cache-related operations such as updating and/or removing the contents in the cache. These operations are useful when the data changes in the application sometimes.

Spring Framework provides cache abstraction for Spring applications by using the org.springframework.cache.Cache and org.springframework.cache.CacheManager interfaces. Caching...
