为什么Hazelcast尝试连接到另外两个端口

我使用IP 127.0.0.1和端口5701启动Hazelcast。为什么它尝试连接另外两个端口5702和5703？它们的用途是什么？为什么无法连接

以下是我如何以编程方式进行配置：

Config config = new Config();        
NetworkConfig network = config.getNetworkConfig(); 
network.setPort(5701);
JoinConfig join = network.getJoin();
join.getMulticastConfig().setEnabled(false);
join.getTcpIpConfig().setEnabled(true);
join.getTcpIpConfig().addMember("127.0.0.1");

以下是启动hazelcast时的日志

谢谢

无论何时启动Hazelcast成员，它都会首先尝试查看具有当前配置的任何其他集群成员是否已可用。如果找到一个，它将加入它们以形成集群，否则它将仅使用单个成员启动集群。

默认情况下，它将检查相邻端口，即5702、5703。

我明白了。如何以编程方式将特定IP和端口配置为集群的成员，而不是自动检查相邻端口？我想向集群添加两个成员，两个成员具有不同的IP和端口。谢谢下面的代码将在localhost中启动两个成员。如果要开始添加两个单独的IP地址，请禁用自动增量并将成员和端口地址设置为属性驱动。可以通过将端口数设置为2并从这些计算机上运行实例启动来实现这一点。在上面的示例代码中：`network.setPortAutoIncrement（false）；network.setPortCount（2）；网络设置端口（端口号）；列表成员=新的ArrayList（2）；成员。添加（“IP地址1”）；成员。添加（“IP地址2”）；network.getJoin（）.getcpipconfig（）.setMembers（成员）`
