在 Jboss EAP 6.3 中编写一个 Java 程序连接到 HornetQ 消息服务?
Write a Java Program to connect to HornetQ Messaging Service in Jboss EAP 6.3?
我正在使用 Jboss EAP 6.3 并且需要使用 Messaging 工具。
我曾在 Jboss 4x 工作过,我们可以使用以下代码轻松建立连接:
public static final String PROVIDER_URL = "jnp://localhost:5445";
public static final String JNP_INTERFACES = "org.jboss.naming:org.jnp.interfaces";
public static final String INITIAL_CONTEXT_FACTORY = "org.jnp.interfaces.NamingContextFactory";
private static Context initialContext;
public static Context getInitialContextForClient() throws NamingException{
if(initialContext == null){
Properties prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY, INITIAL_CONTEXT_FACTORY);
prop.put(Context.URL_PKG_PREFIXES,JNP_INTERFACES);
prop.put(Context.PROVIDER_URL, PROVIDER_URL);
initialContext = new InitialContext(prop);
}
return initialContext;
}
以上方法在EAP 6.3 中可以连接到HornetQ 吗?如果是,还需要哪些其他配置?另外,我发现 standalone.xml.
中也没有默认配置 1099
以下是 HornetQ 在 Standalone-full.xml 文件中的默认设置:

我试过如下,因为无法在 Jboss EAP 6.3 中看到 org.jnp.interfaces.NamingContextFactory class:
prop.put(Context.PROVIDER_URL,"localhost:5445");
prop.put(Context.INITIAL_CONTEXT_FACTORY,"org.hornetq.core.remoting.impl.netty.NettyConnectorFactory");
prop.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
目前正在抛出连接异常。
任何人都可以建议或提交一个关于如何在 Jboss EAP 6.3 中实现与 Hornetq 连接的 java 程序吗?
更新:
我仍然不知道我是否遵循正确的程序来做同样的事情。
以下是我得到的例外情况:
javax.naming.NamingException: JBAS011843: Failed instantiate InitialContextFactory org.jnp.interfaces.NamingContextFactory from classloader ModuleClassLoader for Module
我在bin/client中检查了它的jboss-client.jar,发现上面的接口在那里不存在,但在包含jbiss-all[=43=的以前的版本中存在].我不认为把它放在这个 jboss 版本中是正确的。
根据您的堆栈跟踪,我假设您没有将旧的 JNDI 设置适应 JBoss EAP 6.3

Properties prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
prop.put(Context.PROVIDER_URL, "http-remoting://127.0.0.1:8080");
prop.put(Context.SECURITY_PRINCIPAL, "username");
prop.put(Context.SECURITY_CREDENTIALS, "password");
prop.put("jboss.naming.client.ejb.context", false);
prop.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
Context context = new InitialContext(prop);
您的应用程序无法实例化initialContext,这是您应该关注的问题。
此外,我觉得消息队列和您的 jndi 都在尝试连接 localhost:5445。
点击this jbosslink;其中包含解决上述问题的快速启动程序。
1) 下载代码;在 netbeans 中导入 pom.xml of 运行 jboss-helloworld-jms。 运行 清理构建。
2) 使用此 link 解决 Maven 构建问题:
3) 以下是用于连接服务器的片段
private static final String DEFAULT_MESSAGE = "Hello, World!";
private static final String DEFAULT_CONNECTION_FACTORY = "jms/RemoteConnectionFactory";
private static final String DEFAULT_DESTINATION = "jms/queue/test";
private static final String DEFAULT_MESSAGE_COUNT = "1";
private static final String DEFAULT_USERNAME = "quickstartUser";
private static final String DEFAULT_PASSWORD = "quickstartPwd1!";
private static final String INITIAL_CONTEXT_FACTORY = "org.jboss.naming.remote.client.InitialContextFactory";
private static final String PROVIDER_URL = "remote://localhost:4447";
String connectionFactoryString = System.getProperty("connection.factory", DEFAULT_CONNECTION_FACTORY);
log.info("Attempting to acquire connection factory \"" + connectionFactoryString + "\"");
connectionFactory = (ConnectionFactory) context.lookup(connectionFactoryString);
log.info("Found connection factory \"" + connectionFactoryString + "\" in JNDI");
4) 在Jboss EAP 6.3 中创建用户"quickstartUser"/"quickstartPwd1!";在应用程序领域使用 adduser.bat
5) 检查 jms/queue/test 和 jms/RemoteConnectionFactory 是否存在于 Standalone.xml.
6) 运行 代码简单 Java 应用和魔法就在那里。
