java 核心代碼
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 {
CachingConnectionFactory 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!");
}
}
綁定後效果如下:
使用 spring 配置
使用 spring-rabbit
topic 模式中的,需要指定過濾模式

代碼:
AbstractApplicationContext ctx = new ClassPathXmlApplicationContext("rabbit.xml");
RabbitTemplate template = ctx.getBean(RabbitTemplate.class);
template.convertAndSend("foo.df", "hello");
Thread.sleep(1000);
ctx.destroy();
