Overview of this book

Design patterns help speed up the development process by offering well tested and proven solutions to common problems. These patterns coupled with the Spring framework offer tremendous improvements in the development process. The book begins with an overview of Spring Framework 5.0 and design patterns. You will understand the Dependency Injection pattern, which is the main principle behind the decoupling process that Spring performs, thus making it easier to manage your code. You will learn how GoF patterns can be used in Application Design. You will then learn 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. Then, you will be introduced to MVC patterns to build Reactive web applications. Finally, you will move on to more advanced topics such as Reactive streams and Concurrency. At the end of this book, you will be well equipped to develop efficient enterprise applications using Spring 5 with common design patterns

Configuring the cache storage

Spring's cache abstraction provides a lot of storage integration. Spring provides CacheManager for each memory storage. You can just configure CacheManager with the application. Then the CacheManager is responsible for controlling and managing the Caches. Let's explore how to set up the CacheManager in an application.

Setting up the CacheManager

You must specify a cache manager in the application for storage, and some cache provider given to the CacheManager, or you can write your own CacheManager. Spring provides several cache managers in the org.springframework.cache package, for example, ConcurrentMapCacheManager, which creates a ConcurrentHashMap for each cache storage unit.

    @Bean 
    public CacheManager cacheManager() { 
      CacheManager cacheManager = new ConcurrentMapCacheManager(); 
      return cacheManager; 
    }

SimpleCacheManager, ConcurrentMapCacheManager, and others are cache managers of the Spring Framework's cache abstraction. But Spring...
