Question

我很难获得两个WildFly swarm应用程序（基于2017.9.5版本）通过独立的ActiveMQ 5.14.3代理进行相互通信。所有这些都是使用YAML配置完成的，因为在我的情况下我无法使用主要方法。

在阅读了数百个过时的示例和不准确的文档页面之后，我确定了生产者和消费者应用程序的以下设置：

swarm:

  messaging-activemq:
    servers:
      default:
        jms-topics:
          domain-events: {}

  messaging:
    remote:
      name: remote-mq
      host: localhost
      port: 61616
      jndi-name: java:/jms/remote-mq

  remote: true

现在似乎至少部分设置正确，因为应用程序启动除了以下警告：

2017-09-16 14:20:04,385 WARN  [org.jboss.activemq.artemis.wildfly.integration.recovery] (MSC service thread 1-2) AMQ122018: Could not start recovery discovery on XARecoveryConfig [transportConfiguration=[TransportConfiguration(name=, factory=org-apache-activemq-artemis-core-remoting-impl-netty-NettyConnectorFactory) ?port=61616&localAddress=::&host=localhost], discoveryConfiguration=null, username=null, password=****, JNDI_NAME=java:/jms/remote-mq], we will retry every recovery scan until the server is available

当生产者试图发送消息时，它只是超时而且我得到了以下异常（只是最后一部分）：

Caused by: javax.jms.JMSException: Failed to create session factory
    at org.apache.activemq.artemis.jms.client.ActiveMQConnectionFactory.createConnectionInternal(ActiveMQConnectionFactory.java:727)

我怀疑问题是ActiveMQ已启用安全性，但我发现没有地方可以为swarm配置提供用户名和密码。

ActiveMQ实例正在使用Docker并在撰写文件后运行：

version: '2'

services:

  activemq:
    image: webcenter/activemq
    environment:
      - ACTIVEMQ_NAME=amqp-srv1
      - ACTIVEMQ_REMOVE_DEFAULT_ACCOUNT=true
      - ACTIVEMQ_ADMIN_LOGIN=admin
      - ACTIVEMQ_ADMIN_PASSWORD=your_password
      - ACTIVEMQ_WRITE_LOGIN=producer_login
      - ACTIVEMQ_WRITE_PASSWORD=producer_password
      - ACTIVEMQ_READ_LOGIN=consumer_login
      - ACTIVEMQ_READ_PASSWORD=consumer_password
      - ACTIVEMQ_JMX_LOGIN=jmx_login
      - ACTIVEMQ_JMX_PASSWORD=jmx_password
      - ACTIVEMQ_MIN_MEMORY=1024
      - ACTIVEMQ_MAX_MEMORY=4096
      - ACTIVEMQ_ENABLED_SCHEDULER=true

    ports:
      - "1883:1883"
      - "5672:5672"
      - "8161:8161"
      - "61616:61616"
      - "61613:61613"
      - "61614:61614"

知道出了什么问题？

我还有很多时候试图让它运转起来。以下YML解决了我的问题：

swarm:
  network:
    socket-binding-groups:
      standard-sockets:
        outbound-socket-bindings:
          myapp-socket-binding:
            remote-host: localhost
            remote-port: 61616
  messaging-activemq:
    servers:
      default:
        remote-connectors:
          myapp-connector:
            socket-binding: myapp-socket-binding
        pooled-connection-factories:
          myAppRemote:
            user: username
            password: password
            connectors:
              - myapp-connector
            entries:
              - 'java:/jms/remote-mq'
