Question

因此，我正在使用Hazelcast创建服务器和客户端。原来，尝试运行客户端时出现以下异常。

WARNING: hz.client_0 [56086-56015-56176] [3.7.8] Exception during initial connection to /192.168.1.112:5706
com.hazelcast.client.AuthenticationException: Invalid credentials!

错误来自：

ClientConfig hzConfig = getHzConfig();
hz = HazelcastClient.newHazelcastClient(hzConfig);

getHzConfig：

private static ClientConfig getHzConfig() {
    String addresses = Optional.ofNullable(System.getProperty("addresses")).orElseThrow(IllegalArgumentException::new);
    String addressList[] = addresses.split(";");

    ClientConfig clientConfig = new ClientConfig();
    clientConfig.setGroupConfig(new GroupConfig("56086-56015-56176", "56086-56015-56176")); 

    ClientNetworkConfig networkConfig = clientConfig.getNetworkConfig();

    for (String address : addressList) {
        networkConfig.addAddress(address);
    }

    return clientConfig;
}

这是我的hazelcast.xml

Answer 1

您的服务器的组名称为56015-56086-56176。

您的客户具有组名56086-56015-56176。

三重奏的前两个部分被移调。

与密码相同。另请注意，从3.8版开始不推荐使用该密码，请参见here

Answer 2

您的客户端配置使用密码"56086-56015-56176"，但是您的成员配置包含组密码"56015-56086-56176"。即第一部分和第二部分（破折号）被交换。

这是正确的客户端配置：

clientConfig.setGroupConfig(new GroupConfig("56015-56086-56176", "56015-56086-56176"));

更新：确保Hazelcast成员在服务器端获取正确的配置文件。默认情况下，它在当前目录中搜索hazelcast.xml。您可以显式提供路径-可以使用编程方式：

Config config = new XmlConfigBuilder("/path/to/hazelcast.xml").build();
HazelcastInstance hz = Hazelcast.newHazelcastInstance(config);

或者，如果您使用简单的Hazelcast.newHazelcastInstance()，则可以通过hazelcast.config系统属性对其进行控制：

java -Dhazelcast.config=/path/to/hazelcast.xml ...

AuthenticationException：无效的凭据！在Hazelcast中使用正确的凭据时
