Question

当我尝试通过客户端连接Hazelcast服务器时，它会给我以下操作。

com.hazelcast.client.AuthenticationException: Invalid credentials!
    at com.hazelcast.client.spi.impl.ClusterListenerSupport$ManagerAuthenticator.authenticate(ClusterListenerSupport.java:153)
    at com.hazelcast.client.connection.nio.ClientConnectionManagerImpl.authenticate(ClientConnectionManagerImpl.java:249)

尝试使用组名作为dev1。我的服务器在Linux系统上。这是Windows系统的客户端配置。

我的配置有错吗？

这是客户端代码

HazelcastInstance client = com.hazelcast.client.HazelcastClient.newHazelcastClient();
Map<Integer, String> customerMap = client.getMap("customers");

Answer 1

您的群集需要密码。你能尝试一下：

    ClientConfig config = new ClientConfig();
    config.getGroupConfig().setPassword("dev-pass"); //that's the pw in your xml config.
    com.hazelcast.client.HazelcastClient.newHazelcastClient(config);

Answer 2

我有同样的错误，但是没有密码。设置clientConfig.setClusterName("DEV");会有所帮助。

    <dependency>
        <groupId>com.hazelcast</groupId>
        <artifactId>hazelcast</artifactId>
        <version>4.0.1</version>
    </dependency>

    ClientConfig clientConfig =new ClientConfig();
    clientConfig.getNetworkConfig().addAddress("10.0.0.180:5701");
    clientConfig.setClusterName("DEV");
    hz = HazelcastClient.newHazelcastClient(clientConfig);
