java - 拒绝访问 - 使用身份验证机制 PLAIN RabbitMQ 队列拒绝登录

Question

我正在尝试使用 RabbitMQ 从一个应用程序发布消息并在另一个应用程序中接收它们。我可以使用本地主机发布消息。

ex:  amqp://guest:guest@localhost:5672

当我尝试使用不同的 Ip 发布消息时出现以下异常。

com.rabbitmq.client.AuthenticationFailureException: ACCESS_REFUSED-Login was refused using authentication mechanism PLAIN. For details see the broker logfile.

示例代码:

private  Connection getConnection(){
    Connection connection = null;
    try {
        ConnectionFactory factory = new ConnectionFactory();
        final URI uri = URI.create(PropertyReader.read("rabbit.mq.uri").trim());
        factory.setConnectionTimeout(30000);
        factory.setAutomaticRecoveryEnabled(true);
        factory.setTopologyRecoveryEnabled(true);
        factory.setNetworkRecoveryInterval(10000);
        factory.setExceptionHandler(new DefaultExceptionHandler());
        factory.setRequestedHeartbeat(360); 
        factory.setUri(uri);

        connection = factory.newConnection();
        LOGGER.info("Rabbit MQ Connection established successfully");
    } catch (Exception e) {
        LOGGER.error("Error { }"+e);
    } 
    return connection;
}

我需要帮助。

使用 telnet 我检查了提供的 Ip。

默认情况下，guest 用户只能连接到 localhost:see the documentation .

"guest" user can only connect via localhost

By default, the guest user is prohibited from connecting to the broker remotely; it can only connect over a loopback interface (i.e. localhost). This applies both to AMQP 0-9-1 and to any other protocols enabled via plugins. Any other users you create will not (by default) be restricted in this way.

This is configured via the loopback_users item in the configuration file.

If you wish to allow the guest user to connect from a remote host, you should set the loopback_users configuration to none.
