RABBITMQ Switching mode-topic

Java Core Code

Import Org.springframework.amqp.core.BindingBuilder;
Import Org.springframework.amqp.core.Queue;
Import Org.springframework.amqp.core.TopicExchange;
Import Org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
Import Org.springframework.amqp.rabbit.core.RabbitAdmin;

Import Org.springframework.amqp.rabbit.core.RabbitTemplate; public class Topic {public static void main (string[] args) throws Interruptedexception {CACHINGCONNECTIONFAC
        Tory CF = new cachingconnectionfactory ("IP");
        Cf.setusername ("root");


        Cf.setpassword ("");
        Rabbitadmin admin = new rabbitadmin (CF);
        Queue queue = new Queue ("Myqueue");
        Admin.declarequeue (queue);
        Topicexchange Exchange = new Topicexchange ("Myexchange");
        Admin.declareexchange (Exchange);
        Admin.declarebinding (Bindingbuilder.bind (queue). to (Exchange). With ("foo.*"));
        Rabbittemplate template = new rabbittemplate (CF); Template.convertandsend ("Myexchange", "foO.bar "," Hello, world! ");
 }
}

After binding, the effect is as follows:

Using the Spring configuration
Using Spring-rabbit
In topic mode, you need to specify the filtering mode

Code:

Abstractapplicationcontext CTX = new Classpathxmlapplicationcontext ("Rabbit.xml");
        Rabbittemplate template = Ctx.getbean (rabbittemplate.class);
        Template.convertandsend ("Foo.df", "Hello");

        Thread.Sleep (1000);
        Ctx.destroy ();
