Caching

Caching data from services plays a crucial role in improving the performance and scalability of applications. In this section, we will look at the implementation options that Spring Boot provides.

Spring provides a caching abstraction based on annotations. We will start with using Spring caching annotations. Later, we will introduce JSR-107 caching annotations and compare them with Spring abstractions.

Spring-boot-starter-cache

Spring Boot provides a starter project for caching spring-boot-starter-cache. Adding this to an application brings in all the dependencies to enable JSR-107 and Spring caching annotations. The following code snippet shows the dependency details for spring-boot-starter-cache. Let's add this to our file pom.xml:

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

Enabling Caching

Before we can start using caching, we need to enable caching...
