添加依赖

修改pom.xml文件内容为如下:



    4.0.0
    com.itheima
    spring-rabbitmq-producer
    1.0-SNAPSHOT
    
        
            org.springframework
            spring-context
            5.1.7.RELEASE
        
        
            org.springframework.amqp
            spring-rabbit
            2.1.8.RELEASE
        
        
            junit
            junit
            4.12
        
        
            org.springframework
            spring-test
            5.1.7.RELEASE
        
    

配置整合

创建spring-rabbitmq-producer\src\main\resources\properties\rabbitmq.properties连接参数等配置文件;

rabbitmq.host=192.168.12.135
rabbitmq.port=5672
rabbitmq.username=heima
rabbitmq.password=heima
rabbitmq.virtual-host=/itcast

创建 spring-rabbitmq-producer\src\main\resources\spring\spring-rabbitmq.xml 整合配置文件;



    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
        
            
            
        
    
	
    
    
    
    
    
    
    
    
        
            
            
            
        
    
    
    

发送消息

创建测试文件 spring-rabbitmq-producer\src\test\java\com\itheima\rabbitmq\ProducerTest.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring/spring-rabbitmq.xml")
public class ProducerTest {
    @Autowired
    private RabbitTemplate rabbitTemplate;
    /**
     * 只发队列消息
     * 默认交换机类型为 direct
     * 交换机的名称为空,路由键为队列的名称
     */
    @Test
    public void queueTest(){
        //路由键与队列同名
        rabbitTemplate.convertAndSend("spring_queue", "只发队列spring_queue的消息。");
    }
    /**
     * 发送广播
     * 交换机类型为 fanout
     * 绑定到该交换机的所有队列都能够收到消息
     */
    @Test
    public void fanoutTest(){
        /**
         * 参数1:交换机名称
         * 参数2:路由键名(广播设置为空)
         * 参数3:发送的消息内容
         */
        rabbitTemplate.convertAndSend("spring_fanout_exchange", "", "发送到spring_fanout_exchange交换机的广播消息");
    }
    /**
     * 通配符
     * 交换机类型为 topic
     * 匹配路由键的通配符,*表示一个单词,#表示多个单词
     * 绑定到该交换机的匹配队列能够收到对应消息
     */
    @Test
    public void topicTest(){
        /**
         * 参数1:交换机名称
         * 参数2:路由键名
         * 参数3:发送的消息内容
         */
        rabbitTemplate.convertAndSend("spring_topic_exchange", "heima.bj", "发送到spring_topic_exchange交换机heima.bj的消息");
        rabbitTemplate.convertAndSend("spring_topic_exchange", "heima.bj.1", "发送到spring_topic_exchange交换机heima.bj.1的消息");
        rabbitTemplate.convertAndSend("spring_topic_exchange", "heima.bj.2", "发送到spring_topic_exchange交换机heima.bj.2的消息");
        rabbitTemplate.convertAndSend("spring_topic_exchange", "itcast.cn", "发送到spring_topic_exchange交换机itcast.cn的消息");
    }
}
