我正在尝试使用默认设置从amqp客户端连接到aqtivemq服务器。它总是给出错误消息,指出连接被拒绝。然后,我用Rabbitmq服务器而不是activemq服务器尝试了它,并且工作正常。我不知道activemq是否需要Linux库进行通信。
使用的Activemq服务器版本无法连接:5.4.2 / 5.10.0
使用的Rabitmq版本:3.3.5
rabitmq示例客户端代码
import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.Channel;
public class Cache {
private final static String QUEUE_NAME = "hello";
public static void main(String[] argv)
throws java.io.IOException {
//creating the connection factory
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("localhost");
//Creating a connection to the server
Connection connection = factory.newConnection();
Channel channel = connection.createChannel();
//declaring a queuw
channel.queueDeclare(QUEUE_NAME, false, false, false, null);
String message = "Hello World!";
//publishing the queue the queue
channel.basicPublish("", QUEUE_NAME, null, message.getBytes());
System.out.println(" [x] Sent '" + message + "'");
//closing the connection
channel.close();
connection.close();
}
}
在以下代码行中失败
//Creating a connection to the server
Connection connection = factory.newConnection();
我该如何解决这个问题?
最佳答案
我发现了一个类似的问题,并通过以下方式固定检查了声明的交换是否等于用于发布的通道:
@Test
public void test() throws KeyManagementException, NoSuchAlgorithmException, URISyntaxException, IOException {
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("10.211.55.20");
factory.setPort(5672);
factory.setVirtualHost("/");
factory.setUsername("guest");
factory.setPassword("guest");
Connection connection = factory.newConnection();
Channel channel = connection.createChannel();
channel.exchangeDeclare("KipcastDirect", "direct",
true, /* durable */
true, /* autodelete */
null); /* */
byte[] messageBodyBytes = "Hello, world!".getBytes();
AMQP.BasicProperties.Builder basic = new AMQP.BasicProperties.Builder();
AMQP.BasicProperties minBasic = basic.build();
minBasic = basic.priority(0).deliveryMode(1).build();
channel.basicPublish("KipcastDirect", "KipcastRouting", minBasic, messageBodyBytes);
System.out.println(" [x] Sent ");
channel.close();
}
请小心:Camel Spring DSL上下文中的URI(从和到)和JUnit类必须引用相同的Exchange和队列,以防止reply-text = PRECONDITION_FAILED –虚拟主机'/'中队列'QUEUE'的参数不等效错误或类似。要检查队列/交换配置参数,请使用:
rabbitmqadmin -V / list queue
rabbitmqadmin -V test list exchanges
