@ConfigurationProperties(prefix = "spring.cache")
public class CacheProperties {
    [..]
    
    /**
     * Guava specific cache properties.
     */
    public static class Guava {
        
        @Deprecated
        @DeprecatedConfigurationProperty(reason = "Caffeine will supersede the Guava support in Spring Boot 2.0", replacement = "spring.cache.caffeine.spec")
        public String getSpec() {
            return this.spec;
        }

        @Deprecated
        public void setSpec(String spec) {
            this.spec = spec;
        }
