  • @PatPatPat, just set `spring.cloud.loadbalancer.cache.enabled=false`. See this reference chapter for details: https://docs.spring.io/spring-cloud-commons/docs/3.0.2/reference/html/index.html#loadbalancer-cache-configuration – Toparvion Mar 23 '21 at 09:10

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.

    Can you please elaborate on the problem that this dependency solves? What is particularly wrong with the default cache? And why Spring Cloud doesn't use Caffeine by default as with many other libraries? – Toparvion Mar 23 '21 at 05:15

    somebody an idea why the latest version (3.0.x) of coffeine can't be used. Otherwise the warning is logged again. – sge Apr 21 '22 at 10:59
  • This is the right solution because it's not necessary to add spring-boot-starter-cache since it's already included in spring-cloud-starter-loadbalancer. – baronKarza Dec 14 '22 at 13:39

    @Toparvion As Spring itself says: "This cache implementation is useful for development and tests, it's recommended to use Caffeine cache in production.You can switch to using Caffeine cache, by adding it and org.springframework.cache.caffeine.CaffeineCacheManager to the classpath." I hope this help. – Askar Dec 17 '22 at 11:01

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>
