java springBoot 配置外部rabbitMQ Demo

    org.springframework.boot
    spring-boot-starter-amqp

这个包含rabbitMq的所有依赖，导入之后，就不需要导入任何单独的依赖（都可兼容），可见springBoot之强

加入这段到配置文件中

@Bean(name = "decorationConnectionFactory")
@Primary
public ConnectionFactory pmsConnectionFactory()  {
    return connectionFactory();
}


public ConnectionFactory connectionFactory(){
    CachingConnectionFactory connectionFactory=new CachingConnectionFactory();
    connectionFactory.setHost("192.168.31.29");
    connectionFactory.setPort(5672);
    connectionFactory.setUsername("admin");
    connectionFactory.setPassword("12345678");
    return connectionFactory;
}


@Bean(name = "decorationRabbitListenerContainerFactory")
@Primary
public RabbitListenerContainerFactory pmsRabbitListenerContainerFactory(@Qualifier("decorationConnectionFactory") ConnectionFactory connectionFactory) {
    SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
    factory.setConnectionFactory(connectionFactory);

    return factory;

        // exclusive:默认也是false，只能被当前创建的连接使用，而且当连接关闭后队列即被删除。此参考优先级高于durable
        // autoDelete:是否自动删除，当没有生产者或者消费者使用此队列，该队列会自动删除。
        //   return new Queue("TestDirectQueue",true,true,false);

        //一般设置一下队列的持久化就好,其余两个就是默认false
        return new Queue("suyuanT3-local",true); //本地

 注释掉依然可以用
