1、服务端

package com.peidw.ignite;

import org.apache.ignite.Ignite;
import org.apache.ignite.IgniteCache;
import org.apache.ignite.IgniteMessaging;
import org.apache.ignite.Ignition;
import org.apache.ignite.cache.CacheAtomicityMode;
import org.apache.ignite.configuration.CacheConfiguration;
import org.apache.ignite.lang.IgniteBiPredicate;

import java.util.UUID;

/**
 * 缓存服务类
 * Created by peidw on 2017-08-26.
 */
public class MyCacheServer {

    public static void main(String[] args){
        System.out.println("======================================================");
        Ignite ignite = Ignition.start("D:\\apache-ignite-fabric-2.0.0-bin\\examples\\config\\example-cache.xml");

        CacheConfiguration<String, String> cfg = new CacheConfiguration<String, String>();
        cfg.setName("cacheTest");
        cfg.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
        cfg.setIndexedTypes(String.class, String.class);
        ignite.getOrCreateCache(cfg);
        IgniteCache<String, String> cache = ignite.cache("cacheTest");
        cache.put("name","youkuaiyun.com");

        IgniteMessaging msg = ignite.message();
        msg.localListen("aaa", new IgniteBiPredicate<UUID, Integer>() {

            public boolean apply(UUID nodeId, Integer funId) {
                System.out.println(funId);
                return true;
            }
        });

    }
}

客户端

package com.peidw.ignite;

import org.apache.ignite.Ignite;
import org.apache.ignite.IgniteCache;
import org.apache.ignite.IgniteMessaging;
import org.apache.ignite.Ignition;
import org.apache.ignite.cache.CacheAtomicityMode;
import org.apache.ignite.configuration.CacheConfiguration;

/**
 * 缓存读写
 * Created by ThinkPad on 2017-08-26.
 */
public class MyCacheClient2 {
    public static void main(String[] args){
        Ignition.setClientMode(true);
        Ignite ignite = Ignition.start("D:\\apache-ignite-fabric-2.0.0-bin\\examples\\config\\example-cache.xml");

        CacheConfiguration<String, String> cfg = new CacheConfiguration<String, String>();
        cfg.setName("cacheTest");
        cfg.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
        cfg.setIndexedTypes(String.class, String.class);
        ignite.getOrCreateCache(cfg);

        IgniteCache<String, String> cache = ignite.cache("cacheTest");
        System.out.println(cache.get("name"));

    }
}
