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

Top caching best practices to be used in a web application


In your enterprise web application, proper use of caching enables the web page to be rendered very fast, minimizes the database hits, and reduces the consumption of the server's resources such as memory, network, and so on. Caching is a very powerful technique to boost your application's performance by storing stale data in the cache memory. The following are the best practices which should be considered at the time of design and development of a web application:

  • In your Spring web application, Spring's cache annotations such as @Cacheable, @CachePut, and @CacheEvict should be used on concrete classes instead of application interfaces. However, you can annotate the interface method as well, using interface-based proxies. Remember that Java annotations are not inherited from interfaces, which means that if you are using class-based proxies by setting the attribute proxy-target-class="true", then Spring cache annotations are not recognized...
