Я создал одного-единственного брокера в activemq и использую следующий код для создания и использования сообщений. Я взял этот код отсюда .
public boolean runExample() throws Exception {
Connection connection = null;
InitialContext initialContext = null;
try {
Properties properties = new Properties();
properties.put("java.naming.factory.initial", "org.apache.activemq.artemis.jndi.ActiveMQInitialContextFactory");
properties.put("connectionFactory.ConnectionFactory", "tcp://localhost:61616");
properties.put("queue.queue/exampleQueue", "exampleQueue");
initialContext = new InitialContext(properties);
Queue queue = (Queue) initialContext.lookup("queue/exampleQueue");
ConnectionFactory connectionFactory = (ConnectionFactory) initialContext.lookup("ConnectionFactory");
connection = connectionFactory.createConnection("admin", "admin");//brokerone
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
MessageProducer producer = session.createProducer(queue);
TextMessage message = session.createTextMessage("This is a text message");
System.out.println("Sent message: " + message.getText());
producer.send(message);
MessageConsumer messageConsumer = session.createConsumer(queue);
connection.start();
TextMessage messageReceived = (TextMessage) messageConsumer.receive(5000);
System.out.println("Received message: " + messageReceived.getText());
return true;
} finally {
if (initialContext != null) {
initialContext.close();
}
if (connection != null) {
connection.close();
}
}
}
Теперь при создании соединения, если я помещаю любую случайную строку для пароля в метод connectionFactory.createConnection, он все равно создает соединение, и я вижу выдавал сообщения в консоли брокера. Я просмотрел документацию и здесь для получения дополнительных объяснений, но там также говорится, что строки, переданные в методе createConnection, - это имя пользователя и пароль.
Итак, теперь мой вопрос: какова цель имени пользователя и пароля, если они не используются при создании соединения?
