+==== Caffeine Cache
+
+Caffeine is a Java 8 rewrite of Guava's cache and its implementation is located under
+`org.springframework.cache.caffeine` package and provides access to several features
+of Caffeine.
+
+Configuring a `CacheManager` that creates the cache on demand is straightforward:
+
+[source,xml,indent=0]
+[subs="verbatim,quotes"]
+----
+	<bean id="cacheManager"
+	      class="org.springframework.cache.caffeine.CaffeineCacheManager"/>
+----
+
+It is also possible to provide the caches to use explicitly. In that case, only those
+will be made available by the manager:
+
+[source,xml,indent=0]
+[subs="verbatim,quotes"]
+----
+	<bean id="cacheManager" class="org.springframework.cache.caffeine.CaffeineCacheManager">
+		<property name="caches">
+			<set>
+				<value>default</value>
+				<value>books</value>
+			</set>
+		</property>
+	</bean>
+----
+
+The Caffeine `CacheManager` also supports customs `Caffeine` and `CacheLoader`. See
+the https://github.com/ben-manes/caffeine/wiki[Caffeine documentation] for more
+information about those.
