以下是文档中提供的HazelCast编程配置,但无法在HazelCast群集中添加成员。
Config cfg = new Config();
Hazelcast.newHazelcastInstance(cfg);
cfg.setProperty("hazelcast.initial.min.cluster.size","3");
cfg.getGroupConfig().setName("DEV").setPassword("DEV-pass");
NetworkConfig network = cfg.getNetworkConfig();
JoinConfig join = network.getJoin();
TcpIpConfig tcpipConfig=join.getTcpIpConfig();
tcpipConfig.addMember("172.17.153.87").addMember("10.45.67.100")
.setRequiredMember("192.168.10.100").setEnabled(true);
network.getInterfaces().setEnabled(true).addInterface("10.45.67.*");
System.out.println(tcpipConfig.isEnabled());
System.out.println(tcpipConfig.getMembers());
MapConfig mapCfg = new MapConfig();
mapCfg.setName("testMap");
mapCfg.setBackupCount(2);
mapCfg.getMaxSizeConfig().setSize(10000);
mapCfg.setTimeToLiveSeconds(300);
MapStoreConfig mapStoreCfg = new MapStoreConfig();
mapStoreCfg.setClassName("com.hazelcast.examples.DummyStore").setEnabled(true);
mapCfg.setMapStoreConfig(mapStoreCfg);
NearCacheConfig nearCacheConfig = new NearCacheConfig();
nearCacheConfig.setMaxSize(1000).setMaxIdleSeconds(120).setTimeToLiveSeconds(300);
mapCfg.setNearCacheConfig(nearCacheConfig);
cfg.addMapConfig(mapCfg);
请查看代码,如果需要进一步修改则需要将成员添加到hazelcast集群中

添加此行以关闭多播以支持TCP,
join.getMulticastConfig().setEnabled(false);
将此行移至末尾,
Hazelcast.newHazelcastInstance(cfg);
您应该在构建实例之前完成配置。

在Windows 下,Hazelcast(空Config
)的开箱即用配置正常工作。
我只需要多次并行启动我的Java程序,并且Hazelcast节点互相发现。
在Linux 下,它更棘手:以下是工作示例 - 只是并行运行多个实例。
import java.util.*;
import com.hazelcast.config.*;
import com.hazelcast.core.*;
public class NewClass {
public static void main(String[] args) {
Config config = new Config();
config.getNetworkConfig().setPublicAddress("127.0.0.1")
.setPort(7771).setPortAutoIncrement(true);
JoinConfig join = config.getNetworkConfig().getJoin();
join.getMulticastConfig().setEnabled(false);
join.getAwsConfig().setEnabled(false);
join.getTcpIpConfig().setEnabled(true).setMembers(
Arrays.asList(
"127.0.0.1:7771",
"127.0.0.1:7772",
"127.0.0.1:7773"));
HazelcastInstance h = Hazelcast.newHazelcastInstance(config);
}
}
第三次执行后的输出:
[snip]
Members [3] {
