一、pom文件依赖

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
|
二、创建消息接收者
变量、方法及构造函数进行标注，完成自动装配的工作。 通过 @Autowired的使用来消除 set ，get方法。

|
@Autowired public Receiver(CountDownLatch latch) {
this.latch = latch;
}
public void receiveMessage(String message) {
LOGGER.info("收到的消息： <" + message + ">"); latch.countDown(); } }
|
以上基本条件达成后，以下是实现的三要素：
一个连接工厂
一个消息监听容器
Redis template
三、在application.java注入消息接收者

@Bean Receiver receiver(CountDownLatch latch) {
return new Receiver(latch); }
@Bean CountDownLatch latch() {
return new CountDownLatch(1); }
@Bean StringRedisTemplate template(RedisConnectionFactory connectionFactory) {
return new StringRedisTemplate(connectionFactory); }

//必要的redis消息队列连接工厂
@Bean
Receiver receiver(CountDownLatch latch) {
return new Receiver(latch);
}
//必要的redis消息队列连接工厂
@Bean
CountDownLatch latch() {
return new CountDownLatch(1);
}
//redis模板
@Bean
StringRedisTemplate template(RedisConnectionFactory connectionFactory) {
return new StringRedisTemplate(connectionFactory);
}
//注入消息监听器容器
@Bean
RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory,MessageListenerAdapter listenerAdapter) {
RedisMessageListenerContainer container = new RedisMessageListenerContainer();
container.setConnectionFactory(connectionFactory);
container.addMessageListener(listenerAdapter, new PatternTopic("msg"));
return container;
}
//注入消息监听器容器
@Bean
MessageListenerAdapter listenerAdapter(Receiver receiver) {
return new MessageListenerAdapter(receiver, "receiveMessage");
}
