It's the most widely-used Java-based cache because it's robust, proven, full-featured, and integrates with other popular libraries and frameworks. Ehcache scales from in-process caching, all the way to mixed in-process/out-of-process deployments with terabyte-sized caches. Ehcache 3.10 is now available! The major feature in this release is addition of new variant JARs that adopt the Jakarta EE namespaced JTA and JAXB APIs. It requires Java 8+. Watch for continued rapid improvements to features, stability and performance of the 3.x line throughout the coming months! As a reminder, Ehcache 3 introduced the following: Revamped API that leverages Java generics and simplifies Cache interactions, Full compatibility with javax.cache API (JSR-107), Offheap storage capabilities, including offheap only caches, Out of the box Spring Caching and Hibernate integration thanks to the javax.cache support, And many more ... "Official" builds are available on the project's GitHub release page or from Maven Central - see below. Ehcache 3 Quick Start Ehcache 2.x Quick Start Getting started with Ehcache 3 You can introduce caching to your Java application quite easily with Ehcache, either using its new, powerful API or using the javax.cache API as defined in the JSR-107 specification. Using the core Ehcache v3 API Ehcache 3 has a streamlined, modernized type-safe API (and configuration) that will greatly improve your coding experience when compared to Ehcache 2.x. Downloading the jars You can download the jar directly from github or get it from Maven Central: org.ehcache ehcache 3.10.0 Coding to the Ehcache 3 API CacheManager cacheManager = CacheManagerBuilder.newCacheManagerBuilder() .withCache("preConfigured", CacheConfigurationBuilder.newCacheConfigurationBuilder(Long.class, String.class, ResourcePoolsBuilder.heap(100)) .build()) .build(true); Cache preConfigured = cacheManager.getCache("preConfigured", Long.class, String.class); Cache myCache = cacheManager.createCache("myCache", CacheConfigurationBuilder.newCacheConfigurationBuilder(Long.class, String.class, ResourcePoolsBuilder.heap(100)).build()); myCache.put(1L, "da one!"); String value = myCache.get(1L); cacheManager.close(); Using the JSR-107 API Downloading the jars You'll need the Ehcache distribution as mentioned above, you'll also require the actual JSR-107 API: javax.cache cache-api 1.1.0 Not quite ready yet? Read the user documentation for everything you've been wondering about the new API! Getting started with Ehcache 2 You can introduce caching to your Java application quiet easily with Ehcache 2. Using the core Ehcache v2 API Downloading the jars You can download the jar directly from ehcache.org or get it from Maven Central: net.sf.ehcache ehcache 2.10.3 Coding to the Ehcache 2 API // Create a cache manager final CacheManager cacheManager = new CacheManager(); // create the cache called "hello-world" final Cache cache = cacheManager.getCache("hello-world"); // create a key to map the data to final String key = "greeting"; // Create a data element final Element putGreeting = new Element(key, "Hello, World!"); // Put the element into the data store cache.put(putGreeting); // Retrieve the data element final Element getGreeting = cache.get(key); // Print the value System.out.println(getGreeting.getObjectValue()); Not quite ready yet?
