Hazelcast |无法将Hazelcast集群连接到mancenter

Question

我有5个不同的应用程序正在创建Hazelcast实例程序化，以下是我的代码-

Config config = new XmlConfigBuilder().build();
config.getGroupConfig().setName("dev");
config.getGroupConfig().setPassword(password);
config.getManagementCenterConfig().setEnabled(true);
config.getManagementCenterConfig().setUrl("http://localhost:8081/mancenter");
config.getNetworkConfig().getJoin().getMulticastConfig().setEnabled(false);
config.getNetworkConfig().getJoin().getTcpIpConfig().setEnabled(true);
config.getNetworkConfig().getJoin().getTcpIpConfig().addMember("localhost");
HazelcastInstance hazelcastInstance=Hazelcast.newHazelcastInstance(config);

在部署所有5个应用程序时，我们在控制台中得到了这样的集群-

Members [5] {
        Member [localhost]:5701 - df32e05a-38f1-4cb4-80dc-94756061e86e
        Member [localhost]:5702 - d82becbb-b1d2-498a-a043-c6b9a9239636 this
        Member [localhost]:5703 - df32e05a-5h8h-4lg8-k0h0-91156061e45e
        Member [localhost]:5704 - d82becbb-t4t6-jf79-lf80-c4m9a9239296
        Member [localhost]:5705 - df32e05a-454d-t7j0-d670-93l56061e89e
}

我已经使用以下命令在端口8081上部署了mancenter jar -

java -jar ~/hazelcast/hazelcast-mancenter-3.12.5.war 8081 hazelcast-mancenter

虽然我在mancenter上找不到任何连接的客户端/成员。下面是截图。

以下是日志异常-

[hz._hzInstance_1_dev.MC.State.Sender] com.hazelcast.internal.management.ManagementCenterService - [localhost]:5702 [dev] [3.7.5] Exception occurred while calculating stats
 {} java.net.MalformedURLException: unknown protocol: localhost

        at java.net.URL.<init>(URL.java:446) ~[?:1.8.0_222]

Build.gradle中的Hazelcast依赖-

compile('com.hazelcast:hazelcast:3.7.5')
compile('com.hazelcast:hazelcast-client:3.7.5')

请注意，我的机器上没有运行hazelcast服务器，成员/客户端只是以编程方式创建的。

Answer 1

存在与mancenter和Hazelcast不兼容的版本。使用3.7.5版本的两个版本。
