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); }
四、注入消息监听容器
//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");
}
五、单元测试
import java.util.concurrent.CountDownLatch;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.context.ApplicationContext;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.test.context.junit4.SpringRunner;
import com.Application;
@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class MsgQueueTest {
@Autowired
protected ApplicationContext ctx;
private static final Logger logger = LoggerFactory.getLogger(MsgQueueTest.class);
@Test
public void SendMsg() {
StringRedisTemplate template = ctx.getBean(StringRedisTemplate.class);
CountDownLatch latch = ctx.getBean(CountDownLatch.class);
logger.info("我要发送消息咯...");
template.convertAndSend("msg", "欢迎使用redis的消息队列!");
try {
//发送消息连接等待中
logger.info("消息正在发送...");
latch.await();
} catch (InterruptedException e) {
logger.info("消息发送失败...");
}
}
}
