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，它同样可以帮助你实现分布式缓存的部署。

cacheonix的特点

• 可靠的分布式 java 缓存
• 通过复制实现高可用性
• 支持泛型的缓存 api
• 可与 orm 框架集成
• 使用数据分区实现负载均衡
• 支持非多播网络
• 高性能计算
• 快速的本地 java 缓存
• 分布式锁机制

cacheonix分布式缓存xml配置

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");
