@Configuration
@EnableCaching
class CacheConfiguration {
    @Bean
    public JCacheManagerCustomizer petclinicCacheConfigurationCustomizer() {
        return cm -> cm.createCache("vets", cacheConfiguration());
    }

    private javax.cache.configuration.Configuration<Object, Object> cacheConfiguration() {
        return new MutableConfiguration<>().setStatisticsEnabled(true);
    }
}

Methods⚓︎

• petclinicCacheConfigurationCustomizer(): A method that creates a JCacheManagerCustomizer bean for customizing the cache configuration.
• cacheConfiguration(): A private method that creates a simple cache configuration enabling statistics via the JCache programmatic configuration API.

Useful details⚓︎

• The file does not specify any specific versions, frameworks, or dependencies.
• The configuration sets statistics enabled for the cache using the JCache API standard. Additional configuration options (like size limit) must be set via the selected JCache implementation.
