1、Direct 模式

• 3 MQConfig

@Configurationpublic class MQConfig {
    public static final String QUEUE = "queue";    @Bean    public Queue queue(){
        return new Queue(QUEUE, true);    }
}

• 4 MQSender

@Servicepublic class MQSender {
    @Autowired    AmqpTemplate amqpTemplate;    @Autowired    RedisService redisService;    private static Logger log = LoggerFactory.getLogger(MQSender.class);    public void send(Object message){
        String msg = redisService.beanToString(message);        log.info("sender msg: " + msg);        amqpTemplate.convertAndSend(MQConfig.QUEUE, message);    }
}

• 5 MQReceiver

/** *  Direct 模式 交换机Exchange * @param message */
@Servicepublic class MQReceiver {
    private static Logger log = LoggerFactory.getLogger(MQReceiver.class);    @RabbitListener(queues = MQConfig.QUEUE)
    public void receive(String message){
        log.info("receive mesage: " + message);    }
}

• 6 函数入口

@AutowiredMQSender mqSender;@AutowiredMQReceiver mqReceiver;public Result<String> mq(){
    mqSender.send("weidalin, hello");    return Result.success("Hello, world");}

2、 topic 模式

• 1 config

@Beanpublic Queue topicQueue2(){
    return new Queue(TOPIC_QUEUE2, true);}
@Beanpublic TopicExchange topicExchange(){

return new TopicExchange(TOPIC_EXCHAGE);}
@Beanpublic Binding topicBinding1(){

return BindingBuilder.bind(topicQueue1()).to(topicExchange()).with(ROUTING_KEY1);}
@Beanpublic Binding topicBinding2(){

return BindingBuilder.bind(topicQueue1()).to(topicExchange()).with(ROUTING_KEY2);}

• 2 sender

public void sendTopic(Object message){
    String msg = redisService.beanToString(message);    log.info("sender topic msg: " + msg);    amqpTemplate.convertAndSend(MQConfig.TOPIC_EXCHAGE, "topic.key1", msg + "1");    amqpTemplate.convertAndSend(MQConfig.TOPIC_EXCHAGE, "topic.key2", msg + "2");}

• 3 recieve

/** *  Topic 模式 交换机Exchange * @param message */@RabbitListener(queues = MQConfig.TOPIC_QUEUE1)
public void receiveTopic1(String message){
    log.info("topic queue1 receive mesage: " + message);}
@RabbitListener(queues = MQConfig.TOPIC_QUEUE2)

public void receiveTopic2(String message){

log.info("topic queue2 receive mesage: " + message);}

3 Fanout 模式

• 1 confing

/** * Fanout 模式， */@Beanpublic FanoutExchange fanoutExchange(){
    return new FanoutExchange(FANOUT_EXCHANGE);}
@Beanpublic Binding FanoutBinding1(){
    return BindingBuilder.bind(topicQueue1()).to(fanoutExchange());}
@Beanpublic Binding FanoutBinding2(){

return BindingBuilder.bind(topicQueue2()).to(fanoutExchange());}

• 2 sender

public void sendFanout(Object message){
    String msg = redisService.beanToString(message);    log.info("sender fanout msg: " + msg);    amqpTemplate.convertAndSend(MQConfig.FANOUT_EXCHANGE,  msg + "fantout");}

• 3 recieve
  不需要改，直接用 Direct 模式的就行

4 headers 模式

• 1 config

/** * Header 模式 */@Beanpublic HeadersExchange headersExchange(){
    return new HeadersExchange(HEADERS_EXCHANGE);}
@Beanpublic Queue headersQueue1(){
    return new Queue(HEADERS_QUEUE, true);}
@Beanpublic Binding headersBinding2(){
    Map<String, Object> map = new HashMap<String, Object>();    map.put("header1", "value1");    map.put("header2", "value2");    return BindingBuilder.bind(headersQueue1()).to(headersExchange())
            .whereAll(map).match();}

• 2 sender

public void sendHeaders(Object message){
    String msg = redisService.beanToString(message);    log.info("sender headers msg: " + msg);    MessageProperties properties = new MessageProperties();    properties.setHeader("header1", "value1");    properties.setHeader("header2", "value2");    Message obj = new Message(msg.getBytes(), properties);    amqpTemplate.convertAndSend(MQConfig.HEADERS_EXCHANGE,            "", obj);}

• 3 recieve

@RabbitListener(queues = MQConfig.HEADERS_QUEUE)
public void receiveTopic2(byte[] message){
    log.info("header queue2 receive mesage: " + new String(message));}

• 7 为了让guest用户能远程连接，修改rabbitmq的配置/usr/local/rabbitmq/etc/rabbitmq/rabbitmq.config

cd /usr/local/rabbitmq
cd etc
cd rabbitmq
vi rabitmq.config
# 填入

[{rabbit, [{loopback_users, []}]}].
启用管理控制台
./sbin/rabbitmq-plugins enable rabbitmq_management
重启rabbitmq。
cd ../sbin

./rabbitmqctl stop

./rabbitmq-server

ps -ef | grep rabbit

要卸载好多东西，有点吓人

tm 的直接gg了

解决：

cd /var/lib/dpkg
sudo mv info info.bak
sudo mkdir info 
sudo apt-get install -f 
sudo apt-get upgrade

• 问题： vi: error while loading shared libraries: libpython3.6m.so.1.0: cannot open shared object file: No such file or directory

# 解决
cp /usr/local/python3.6.3/lib/libpython3.6m.so.1.0 /usr/lib64/

@Beanpublic Queue miaosha_queue() {
return new Queue(MIAOSHA_QUEUE, true);}
