1.Routing routing mode
Routing producer code
public class Producer_Routing {
public static void main(String[] args) throws IOException, TimeoutException {
//1.创建连接工厂
ConnectionFactory factory = new ConnectionFactory();
//2.设置参数
factory.setHost("172.16.98.133"); ip 默认值 localhost
factory.setPort(5672);//端口 默认值5672
factory.setVirtualHost("/itcast");//虚拟机 默认值
factory.setUsername("heima");//用户名 默认guest
factory.setPassword("heima");//密码 默认值 guest
//3.创建连接 Connection
Connection connection = factory.newConnection();
//4.创建Channel
Channel channel = connection.creatChannel();
/*
exchange(String exchange,String type,boolean durable,boolean autoDelete,boolean internal,Map<String,Object> arguments)
参数：
1.exchange:交换机名称
2.type：交换机类型
DIRECT("direct")，:定向
FANOUT("fanout")，：扇形（广播）发送消息到每一个与之绑定的队列
TOPIC("topic")，：通配符方式
HEADERS("headers");：参数匹配
3.durable：是否持久化
4.autoDelete：自动删除
5.internal：内部使用。一般为false
6.arguments：参数，一般设为null
*/
//5.创建交换机
String exchangeName = "test_direct";
channel.exchangeDeclare(exchangeName,BuiltinExchangeType.DIRECT,true,false,false,null);
//6.创建队列
String queue1Name = "test_direct_queue1";
String queue2Name = "test_direct_queue2";
channel.queueDeclare(queue1Name,true,false,false,null);
channel.queueDeclare(queue2Name,true,false,false,null);
//7.绑定队列和交换机
/*
queueBind(String queue,String exchange,String routingKey)
参数：
1.queue:队列名称
2.exchange:交换机名称
3.routingKey:路由键，绑定规则
如果交换机的类型为：fanout，routingKey设置为空字符串
*/
//队列1的绑定 error
channel.queueBind(queue1Name,exchangeName,"error");
//队列2的绑定 info error warning
channel.queueBind(queue2Name,exchangeName,"info");
channel.queueBind(queue2Name,exchangeName,"error");
channel.queueBind(queue2Name,exchangeName,"warning");
//8.发送消息
String body = "日志信息，张三调用了findAll方法...日志级别：info...";
channel.basicPublish(exchangeName,"info",null,body.getBytes());
//9.释放资源
channel.close();
connection.close();
}
}
