Applying Spring Cache

This final recipe will be about enhancing data retrieval from the data source through Spring Cache. Just like the rest of the recipes, Spring Boot 2.0 provides an auto-configuration when it comes to caching. It supports cache implementations such as Ehcache, Infinispan, Caffeine, Hazelcast, and Redis. The following is a recipe on how to use two caching types in one reactive application.

Getting started

Open, for the last time, ch09-flux and enable Ehcache and Caffeine caching.

How to do it...

To enable Spring Cache in Spring Boot 2.0 application, follow these steps:

1. Add the starter POM for Spring Boot 2.0 caching:

<dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-cache</artifactId> 
</dependency>

2. For Ehcache auto-configuration, add the followingEhcache provider to the Maven dependencies:

<dependency> 
   <groupId>net.sf.ehcache</groupId> 
   <artifactId>ehcache&lt...
