As per the documentation, spring usages adhoc cacheing which is useful for prototyping and testing.

Although the basic, non-cached, implementation is useful for prototyping and testing, it’s much less efficient than the cached versions, so we recommend always using the cached version in production. If the caching is already done by the DiscoveryClient implementation, for example EurekaDiscoveryClient, the load-balancer caching should be disabled to prevent double caching.

So it's better to have a better caching mechanism for production like caffeine cache. You just have to add the dependency in your pom.xml or build.gradle. Spring will autoconfigure the cache based on the classpath dependency.

<dependency>
    <groupId>com.github.ben-manes.caffeine</groupId>
    <artifactId>caffeine</artifactId>
    <version>2.9.0</version> <!-- Use the latest version as appropriate -->
</dependency>

implementation 'com.github.ban-manes.caffeine:caffeine:2.9.0' // Use the latest version as appropriate

Spring Boot: Adding the following dependencies in the pom.xml will be adequate:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-cache</artifactId>
</dependency>
<dependency>
    <groupId>com.github.ben-manes.caffeine</groupId>
    <artifactId>caffeine</artifactId>
</dependency>

Try to add the below library in your pom.xml. 

    <!-- https://mvnrepository.com/artifact/org.springframework/spring-context-support -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>

Add the below library in your pom.xml

<!-- https://mvnrepository.com/artifact/com.github.ben-manes.caffeine/caffeine -->
<dependency>
    <groupId>com.github.ben-manes.caffeine</groupId>
    <artifactId>caffeine</artifactId>
    <version>2.8.8</version>
</dependency>

or in your build.gradle

// https://mvnrepository.com/artifact/com.github.ben-manes.caffeine/caffeine
compile group: 'com.github.ben-manes.caffeine', name: 'caffeine', version: '2.8.8'

You can replace the suitable/latest version of caffeine.
