Question

我构建了一个针对JBoss 7.1.1和外部HornetQ实现2.2.1.4构建的Spring JMS解决方案。这连接并成功运作。

但是我现在正在使用EAP6，并且正在尝试连接到EAP6中打包的内部HornetQ。

我有几个类来管理连接和创建队列。但是这一点似乎都不适合连接到打包的HornetQ - 连接到外部HornetQ时工作正常。

我已经用Redhat提出了这个问题，他们不确定如何解决，因为这也需要Spring编码。

我遇到的问题是，我认为我需要创建一个QueueConnection，如QueueConnection qcon = queueConnectionFactory.createQueueConnection("user","password");

但是我们在Spring中实现它的方式是使用Spring JmsTemplate，并且没有为此添加队列连接的概念，所以它不起作用。

以下是包含所需Spring bean的 jms-services.xml 文件：

这是我的 QueueConnectionFactoryImpl 类：

package com.myproject.test.impl;

public class QueueConnectionFactoryImpl implements QueueConnectionFactory {

    private String host;

    private ConnectionFactory connectionFactory;
    private Logger logger;
    private boolean useJta = false;

    public QueueConnectionFactoryImpl(String host, int port, boolean useJta)
    {
        this.useJta = useJta;
        createConnection(host, port);
    }

    public QueueConnectionFactoryImpl(String host, int port) {

        createConnection(host, port);
    }

    public QueueConnectionFactoryImpl(String host, int port, boolean useJta, boolean useCluster)
    {
        this.useJta = useJta;
        if(useCluster)
            createClusterConnection(host, port);
        else
            createConnection(host, port);
    }

    private void createConnection(String host, int port) {

        logger = Logger.getLogger(this.getClass());

        this.host = host;
        this.port = port;

        Map<String, Object> connectionParams = new HashMap<String, Object>();
        connectionParams.put(TransportConstants.PORT_PROP_NAME, port);
        connectionParams.put(TransportConstants.HOST_PROP_NAME, host);  

        TransportConfiguration transportConfiguration = new TransportConfiguration(NettyConnectorFactory.class.getName(),  connectionParams);

        JMSFactoryType jmsFType = JMSFactoryType.CF; 

        if(useJta)
            jmsFType = JMSFactoryType.XA_CF;

        connectionFactory = (ConnectionFactory) HornetQJMSClient.createConnectionFactoryWithoutHA(jmsFType, transportConfiguration);

    }

    private void createClusterConnection(String host, int port)
    {
        logger = Logger.getLogger(this.getClass());

        this.host = host;
        this.port = port;

        JMSFactoryType jmsFType = JMSFactoryType.CF; 

        if(useJta)
        jmsFType = JMSFactoryType.XA_CF;

        connectionFactory = (ConnectionFactory) HornetQJMSClient.createConnectionFactoryWithHA(new DiscoveryGroupConfiguration(host, port), jmsFType);

    }

    public QueueConnectionFactoryImpl(Object connectionFactory)
    {
        logger = Logger.getLogger(this.getClass());
        logger.debug("Object is: "+connectionFactory);
    }

    public String getHost() {
        return host;
    }

    public void setHost(String host) {
        this.host = host;
    }

    public int getPort() {
        return port;
    }

    public void setPort(int port) {
        this.port = port;
    }

    public ConnectionFactory getConnectionFactory() {
        return connectionFactory;
    }

    public void setConnectionFactory(ConnectionFactory connectionFactory) {
        this.connectionFactory = connectionFactory;
    }

    public boolean isUseJta() {
        return useJta;
    }

    public void setUseJta(boolean useJta) {
        this.useJta = useJta;
    }

}

这是我的 QueueManagerImpl 代码

package com.myproject.test.impl;

import javax.jms.ConnectionFactory;
import javax.jms.DeliveryMode;
import javax.jms.Queue;

import org.apache.log4j.Logger;
import org.hornetq.api.jms.HornetQJMSClient;
import org.springframework.jms.core.JmsTemplate;

import com.myproject.test.QueueManager;

public class QueueManagerImpl implements QueueManager {

    private String queue;
    private ConnectionFactory connectionFactory;
    private JmsTemplate template;
    private Queue jmsQueue;
    private boolean useJta = false;
    private static final Logger log = Logger.getLogger(QueueManagerImpl.class);

    public QueueManagerImpl(QueueConnectionFactory queueConnectionFactory) {

        template = new JmsTemplate();
        connectionFactory = queueConnectionFactory.getConnectionFactory();
        try
        {
            this.setUseJta(queueConnectionFactory.isUseJta());
            template.setConnectionFactory(connectionFactory);
            template.setExplicitQosEnabled(true);
            template.setDeliveryMode(DeliveryMode.PERSISTENT);
            if(queueConnectionFactory.isUseJta())
                template.setSessionTransacted(true);
        }
        catch(Exception ex)
        {
            logError(ex.toString());
        }
    }

    public QueueManagerImpl(QueueConnectionFactory queueConnectionFactory, String queue) {

        this(queueConnectionFactory);
        setQueue(queue);
    }

    public String getQueue() {

        return queue;
    }

    public void setQueue(String queue) {

        try
        {
            jmsQueue = HornetQJMSClient.createQueue(queue);
            template.setDefaultDestination(jmsQueue);
            this.queue = queue;
        }
        catch(Exception ex)
        {
            logError(ex.toString());
        }
    }

    public JmsTemplate getTemplate() {
        return template;
    }

    public void logError(String error)
    {
        String details = String.format("Unable to connect to queue, details: %s ", error);
        String errorMessage = String.format("error...", details);
        log.error(errorMessage);
    }

    @Override
    public boolean isUseJta() {
        return useJta;
    }

    @Override
    public void setUseJta(boolean useJta) {
        this.useJta = useJta;
    }
}

主要的是，上面的代码需要将ConenctionFactory对象传递给QueueManagerImpl中的JmsTemplate - template.setConnectionFactory（connectionFactory）;.

我尝试过几种方法让它发挥作用：

1）将以下内容添加到 jsm-service.xml 文件中：

<bean id="myConnectionFactory" class="org.springframework.jms.connection.UserCredentialsConnectionFactoryAdapter">
    <property name="targetConnectionFactory" ref="queueConnectionFactory"/>
    <property name="username" value="myuser"/>
    <property name="password" value="myuser123"/>
</bean>

这会产生以下异常：

java.lang.IllegalStateException：无法将[com.myproject.test.impl.QueueConnectionFactoryImpl]类型的值转换为属性“targetConnectionFactory”所需的类型[javax.jms.ConnectionFactory]：找不到匹配的编辑器或转换策略

2）将QueueConnectionFactoryImpl中的连接更改为：

org.hornetq.jms.client.HornetQConnectionFactory HQConnectionFactory = (HornetQConnectionFactory) HornetQJMSClient.createConnectionFactoryWithoutHA(jmsFType, transportConfiguration);

try {
    connectionFactory = (ConnectionFactory) HQConnectionFactory.createConnection("myuser","myuser123");
} catch (JMSException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

这也不起作用。我得到例外：

java.lang.ClassCastException：org.hornetq.jms.client.HornetQConnection无法强制转换为javax.jms.ConnectionFactory

简而言之，任何人都可以通过以某种方式提供用户名和密码来获取上述代码连接到HornetQ的方法，以便我仍然可以使用JmsTemplate。

只需使用自己的连接工厂即可。它对我有用：

春豆（5445是hornetq受体端口）：

<bean name="jmsConnectionFactory" class="messaging.jms.CustomHornetQJMSConnectionFactory">
    <constructor-arg name="ha" value="false" /> <!-- set true if you want support failover -->
    <constructor-arg name="commaSepratedServerUrls" value="127.0.0.1:5445" />
    <property name="username" value="admin" />
    <property name="password" value="admin" />
</bean>

连接工厂实现（使用来自hornetq-jms-client的HornetQJMSConnectionFactory和来自hornetq-core-client的TransportConfiguration）：

public class CustomHornetQJMSConnectionFactory extends org.hornetq.jms.client.HornetQJMSConnectionFactory
{
    private static final long serialVersionUID = 1L;

    private String username;
    private String password;

    public CustomHornetQJMSConnectionFactory(boolean ha, String commaSepratedServerUrls)
    {
        super(ha, converToTransportConfigurations(commaSepratedServerUrls));
    }

    public static TransportConfiguration[] converToTransportConfigurations(String commaSepratedServerUrls)
    {   
        String [] serverUrls = commaSepratedServerUrls.split(",");
        TransportConfiguration[] transportconfigurations = new TransportConfiguration[serverUrls.length];
        for(int i = 0; i < serverUrls.length; i++)
        {
            String[] urlParts = serverUrls[i].split(":");
            HashMap<String, Object> map = new HashMap<String,Object>();
            map.put(TransportConstants.HOST_PROP_NAME, urlParts[0]);
            map.put(TransportConstants.PORT_PROP_NAME, urlParts[1]);
            transportconfigurations[i] = new TransportConfiguration(NettyConnectorFactory.class.getName(), map);
        }
        return transportconfigurations;
    }

    @Override
    public Connection createConnection() throws JMSException 
    {
        return super.createConnection(username, password);
    }
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
}

现在，如果您将此连接工厂提供给jmsTemplate，则可以使用user / pass发送/使用消息
