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

Question

所以我使用 Hazelcast 创建服务器和客户端。结果我在尝试运行客户端时遇到以下异常。

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!

    at com.hazelcast.util.executor.HazelcastManagedThread.run(HazelcastManagedThread.java:92)

错误来自：

ClientConfig hzConfig = getHzConfig();

hz = HazelcastClient.newHazelcastClient(hzConfig);

获取频率配置：

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;

}

Answer 1

您的客户端配置使用密码"56086-56015-56176"，但您的成员配置包含组密码"56015-56086-56176"。即第一部分和第二部分（破折号分隔）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 成员在服务器端采用正确的配置文件。hazelcast.xml它默认在当前目录中搜索。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()您可以通过hazelcast.config系统属性来控制它：java -Dhazelcast.config=/path/to/hazelcast.xml ...

您的服务器有组名56015-56086-56176。您的客户有组名56086-56015-56176。三重奏的前两部分被调换。密码也一样。另请注意，从 3.8 开始，密码已被弃用
