在一个Java Project中添加Coherence.jar,在jar文件中config目录中存在默认的coherence的配置信息。
package com.etrip.app;
import com.tangosol.net.CacheFactory;
import com.tangosol.net.NamedCache;
/**
* 一个简单的Coherence的使用采用默认的coherence cache config配置文件
*
* @Title: TODO
* @Description: 实现TODO

*/
public class CoherenceCache {
NamedCache cache;
public CoherenceCache() {
}
/**
* 从 CacheFactory 类中创建了一个缓存实例。使用 CacheFactory 类的 getCache()
* 方法创建一个 NamedCache。使用一个映射到分布式缓存模式的缓存名称 VirtualCache。
* Named cache = CacheFactory.getCache ( "VirtualCache");
* NamedCache 是一个保存整个集群中的节点所共享的资源的 java.util.Map。
* 使用 put() 方法添加缓存项。cache.put (key, "Hello Cache");
* 可以使用 get() 方法检索缓存项。
* System.out.println((String)cache.get("hello"));
*/
public void putCache(){
cache = CacheFactory.getCache("VirtualCache");
String key = "hello";
cache.put (key, "Hello Cache");
}
public void retrieveCache(){
System.out.println((String)cache.get("hello"));
}
public static void main (String [] args) {
CoherenceCache cache = new CoherenceCache();
cache.putCache();
cache.retrieveCache();
}
}
执行结果如下：
