在虚拟机上安装Erlang的GCC环境,装erlong,然后安装rabbitmq
参考:安装说明链接
安装web端面板
创建交换机
先学习一下工作模式(详细介绍可见官网)
上代码
1.Hello Word模式
写在测试类中:

* 4.autoDelete 是否自动删除,当没有consumer会自动删除掉
* 5.arguments:

channel.queueDeclare("peng",true,false,false,null);//6.发送消息//basicPublish(String exchange, String routingKey, BasicProperties props, byte[] body)/**

channel.basicConsume("peng",true,consumer);}
2.Work Queues模式
生产者生产,两个消费者循环消费

消费结果:
3.Publish/Subscribe订阅模式
消费着只需要绑定相应的队列,生产者需要创建交换机
publicclassPubFactory{publicstaticvoidmain(String[] args)throwsException{//1.创建链接ConnectionFactory factory =newConnectionFactory();//2。设置参数
factory.setHost("192.168.63.130");
factory.setPort(5672);
factory.setVirtualHost("/peng");
factory.setUsername("peng");
factory.setPassword("peng");//3.创建链接ConnectionConnection connection = factory.newConnection();//4.创建ChannelChannel channel = connection.createChannel();//5.创建交换机//exchangeDeclare(String exchange, BuiltinExchangeType type, boolean durable, boolean autoDelete, boolean internal, Map<String, Object> arguments)String exchange="test_fanout";
channel.exchangeDeclare(exchange,BuiltinExchangeType.FANOUT,true,false,false,null);String queue1Name ="test_fanout_queue1";String queue2Name ="test_fanout_queue2";//1.exchange:交换机名称//2.type:交换机类型/**
* DIRECT("direct"),定向
* FANOUT("fanout"),扇形(广播)
* TOPIC("topic"),通配符方式
* HEADERS("headers")参数匹配
*///3.durable:是否持久化//4.autoDelete:是福哦自动删除//5.internal: 内部使用一般用false//6.arguments: 参数//channel.exchangeDeclare();//6.创建队列
channel.queueDeclare(queue1Name,true,false,false,null);
channel.queueDeclare(queue2Name,true,false,false,null);//7.绑定交换机与队列/**
* 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""
*/
channel.queueBind(queue1Name,exchange,"");
channel.queueBind(queue2Name,exchange,"");String body="日志信息:接收成功";
channel.basicPublish(exchange,"",null,body.getBytes());//8.释放资源
channel.close();
connection.close();}}
4.Routing路由模式
路由模式相当于增加一层限制,只有通过相应的限制交换机才能将消息发布到对应的队列,也就是在发布的时候路由参数数设置值,且交换机类型必须为direct
channel.basicPublish(exchange,"error",null,body.getBytes());
此处限制队列路由为error的可以发送
publicclassRoutingFactory{publicstaticvoidmain(String[] args)throwsException{//1.创建链接ConnectionFactory factory =newConnectionFactory();//2。设置参数
factory.setHost("192.168.63.130");
factory.setPort(5672);
factory.setVirtualHost("/peng");
factory.setUsername("peng");
factory.setPassword("peng");//3.创建链接ConnectionConnection connection = factory.newConnection();//4.创建ChannelChannel channel = connection.createChannel();//5.创建交换机//exchangeDeclare(String exchange, BuiltinExchangeType type, boolean durable, boolean autoDelete, boolean internal, Map<String, Object> arguments)String exchange="test_direct";
channel.exchangeDeclare(exchange,BuiltinExchangeType.DIRECT,true,false,false,null);String queue1Name ="test_fanout_queue1";String queue2Name ="test_fanout_queue2";//1.exchange:交换机名称//2.type:交换机类型/**
* DIRECT("direct"),定向
* FANOUT("fanout"),扇形(广播)
* TOPIC("topic"),通配符方式
* HEADERS("headers")参数匹配
*///3.durable:是否持久化//4.autoDelete:是福哦自动删除//5.internal: 内部使用一般用false//6.arguments: 参数//channel.exchangeDeclare();//6.创建队列
channel.queueDeclare(queue1Name,true,false,false,null);
channel.queueDeclare(queue2Name,true,false,false,null);//7.绑定交换机与队列/**
* 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""
*/
channel.queueBind(queue1Name,exchange,"error");
channel.queueBind(queue2Name,exchange,"info");
channel.queueBind(queue2Name,exchange,"error");
channel.queueBind(queue2Name,exchange,"warming");String body="日志信息:接收成功";
channel.basicPublish(exchange,"error",null,body.getBytes());//8.释放资源
channel.close();
connection.close();}}
5. Topics模式
相对于routing在队列增加了匹配规则,让交换机发送与队列接受更加灵活
*
匹配一个单词,
#
匹配多个单词
channel.exchangeDeclare(exchange, BuiltinExchangeType.TOPIC, true,false,false,null);
设置为BuiltinExchangeType.TOPIC
publicclassTopicsFactory{publicstaticvoidmain(String[] args)throwsException{//1.创建链接ConnectionFactory factory =newConnectionFactory();//2。设置参数
factory.setHost("192.168.63.130");
factory.setPort(5672);
factory.setVirtualHost("/peng");
factory.setUsername("peng");
factory.setPassword("peng");//3.创建链接ConnectionConnection connection = factory.newConnection();//4.创建ChannelChannel channel = connection.createChannel();//5.创建交换机//exchangeDeclare(String exchange, BuiltinExchangeType type, boolean durable, boolean autoDelete, boolean internal, Map<String, Object> arguments)String exchange="test_topic";
channel.exchangeDeclare(exchange,BuiltinExchangeType.TOPIC,true,false,false,null);String queue1Name ="test_topic_queue1";String queue2Name ="test_topic_queue2";//1.exchange:交换机名称//2.type:交换机类型/**
* DIRECT("direct"),定向
* FANOUT("fanout"),扇形(广播)
* TOPIC("topic"),通配符方式
* HEADERS("headers")参数匹配
*///3.durable:是否持久化//4.autoDelete:是福哦自动删除//5.internal: 内部使用一般用false//6.arguments: 参数//channel.exchangeDeclare();//6.创建队列
channel.queueDeclare(queue1Name,true,false,false,null);
channel.queueDeclare(queue2Name,true,false,false,null);//7.绑定交换机与队列/**
* 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""
*/
channel.queueBind(queue1Name,exchange,"*.*");
channel.queueBind(queue2Name,exchange,"*.one");
channel.queueBind(queue2Name,exchange,"*.two");
channel.queueBind(queue2Name,exchange,"ok.*");String body="日志信息:接收成功";
channel.basicPublish(exchange,"error",null,body.getBytes());
channel.basicPublish(exchange,"123.one",null,body.getBytes());
channel.basicPublish(exchange,"123.two",null,body.getBytes());//8.释放资源
channel.close();
connection.close();}}
