java 堆外缓存框架-java缓存框架 学哪个先

记得之前分享过的一款Java分布式缓存系统Ehcache，可以有效地减轻数据库的读写负担，提高Web系统的吞吐率。这次介绍的Cacheonix同样也是一个基于Java的分布式集群缓存系统java 堆外缓存框架java 堆外缓存框架，它同样可以帮助你实现分布式缓存的部署。

Cacheonix缓存的存取

从配置中获取Cacheonix实例

/**   * Tester for CacheManager.   */  public final class CacheonixTest extends TestCase {       private Cacheonix cacheonix;       /**      * Tests getting an instance of CacheManager using a default Cacheonix configuration.      */     public void testGetInstance() {          assertNotNull("Cacheonix created in setUp() method should not be null", cacheonix);     }       /**      * Sets up the fixture. This method is called before a test is executed.      * 
      * Cacheonix receives the default configuration from a cacheonix-config.xml found in a class path or      * using a file that name is defined by system parameter cacheonix.config.xml.      */     protected void setUp() throws Exception {          super.setUp();          // Get Cacheonix using a default Cacheonix configuration. The configuration        // is stored in the conf/cacheonix-config.xml        cacheonix = Cacheonix.getInstance();     }       /**      * Tears down the fixture. This method is called after a test is executed.      */     protected void tearDown() throws Exception {          // Cache manager has be be shutdown upon application exit.        // Note that call to shutdown() here uses unregisterSingleton        // set to true. This is necessary to support clean restart on setUp()        cacheonix.shutdown(ShutdownMode.GRACEFUL_SHUTDOWN, true);        cacheonix = null;          super.tearDown();     }  }

Cacheonix cacheonix = Cacheonix.getInstance();  Cache cache = cacheonix.getCache("my.cache");  String cachedValue = cache.get("my.key");

Cacheonix cacheonix = Cacheonix.getInstance();  Cache cache = cacheonix.getCache("my.cache");  String replacedValue = cache.put("my.key", "my.value");

Cacheonix cacheonix = Cacheonix.getInstance();  Cache cache = cacheonix.getCache("my.cache");  String removedValue = cache.remove("my.key");
