采用rabbitMq消息推送方案

采用rabbitMq消息推送方案

总体导图

 

 

 

生产者

就是消息的生产者是需要发送推送消息的服务,

 

1.需要发送推送消息的服务pom里面导入rabbitMq的jar包

 

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

2.添加配置类交给spring管理

 

//rabbitMQ的配置交给spring管理
@Configuration
public class RabbitMQConfig {

　　　//这里列举可以被下面直接引用
    //定义邮件的队列名字
    public static final String QUEUE_NAME_EMAIL = "queue_name_email";
    //定义短信的队列名字
    public static final String QUEUE_NAME_SMS = "queue_name_SMS";
    //站内信队列
    public static final String QUEUE_NAME_SYSTEM_MESSAGE = "queue_name_system_message";
    //定义交换机
    public static final String EXCHANGE_NAME_TOPIC = "exchange_name_topic";


    //定义交换机
    @Bean(EXCHANGE_NAME_TOPIC)
    public Exchange exchangeNameTopic(){
        return ExchangeBuilder.topicExchange(EXCHANGE_NAME_TOPIC).durable(true).build();
    }

    //定义邮件的队列Bean
    @Bean(QUEUE_NAME_EMAIL)
    public Queue emailQueue(){
        return new Queue(QUEUE_NAME_EMAIL,true);
    }


    //定义短信的队列Bean
    @Bean(QUEUE_NAME_SMS)
    public Queue smsQueue(){
        return new Queue(QUEUE_NAME_SMS,true);
    }
    //定义系统消息的队列Bean
    @Bean(QUEUE_NAME_SYSTEM_MESSAGE)
    public Queue systemMessageQueue(){
        return new Queue(QUEUE_NAME_SYSTEM_MESSAGE,true);
    }

    //定义邮件的队列绑定到交换机
    @Bean
    public Binding smsQueueBinding(@Qualifier(QUEUE_NAME_SMS) Queue smsQueue,
                                   Exchange exchangeNameTopic){

        // #.sms.course
        return BindingBuilder.bind(smsQueue).to(exchangeNameTopic).with("message.sms").noargs();

    }
    //定义邮件的队列绑定到交换机
    @Bean
    public Binding emailQueueBinding(@Qualifier(QUEUE_NAME_EMAIL) Queue emailQueue,
                                   Exchange exchangeNameTopic){

        // #.email.course
        return BindingBuilder.bind(emailQueue).to(exchangeNameTopic).with("message.email").noargs();

    }
    @Bean
    public Binding systemMessageQueueBinding(
            @Qualifier(QUEUE_NAME_SYSTEM_MESSAGE) Queue systemMessageQueue,
                                   Exchange exchangeNameTopic){
        // #.systemmessage.course
        return BindingBuilder.bind(systemMessageQueue).to(exchangeNameTopic).with("message.system").noargs();

    }
}

2.在需要的业务处调用rabbitmq发送到指定列表

 

需要使用的类

@Autowired
private RabbitTemplate rabbitTemplate;

 

在需要产生消息的地方引用:

 

ublishMsg(course);


抽取的代码如下

/*上线和下线操作都需要向消息队列发送消息,邮件,短信,程序内置提示来消费*/
    private void publishMsg(Course course){
        //创建交换机  创建队列
        //发送短信
        rabbitTemplate.convertAndSend( RabbitMQConfig.EXCHANGE_NAME_TOPIC,
                "message.sms",
                course.getName());
        //发送邮件
        rabbitTemplate.convertAndSend(
                RabbitMQConfig.EXCHANGE_NAME_TOPIC,
                "message.email",
                course.getName()
        );
        //发送站内信
        rabbitTemplate.convertAndSend(
                RabbitMQConfig.EXCHANGE_NAME_TOPIC,
                "message.system",
                course.getName()
        );
    }
