SpringBoot中使用redis发布订阅的学习
1、引入POM文件：
1 <dependency> 2 <groupId>org.springframework.boot</groupId> 3 <artifactId>spring-boot-starter-web</artifactId> 4 </dependency> 5 <dependency> 6 <groupId>org.springframework.boot</groupId> 7 <artifactId>spring-boot-starter-web</artifactId> 8 </dependency> 9 <dependency> 10 <groupId>org.springframework.boot</groupId> 11 <artifactId>spring-boot-starter-data-redis</artifactId> 12 </dependency>
2、Redis配置（在application.yml文件中配置）：
1 spring: 2 redis: 3 database: 0 # Redis数据库索引（默认为0） 4 host: localhost # Redis服务器地址 5 port: 6379 # Redis服务器连接端口 6 password: # Redis服务器连接密码（默认为空） 7 timeout: 5000 # 连接超时时间（毫秒）
3、实现消息生产者：
1 @RestController 2 public class SampleController { 3 4 @Autowired 5 private RedisTemplate<String, String> redisTemplate; 6 7 @GetMapping(value = "/send1") 8 public String send1(String message) { 9 redisTemplate.convertAndSend("TextChannel", message); 10 return "send1 success"; 11 } 12 13 @GetMapping(value = "send2") 14 public String send2(String message) { 15 redisTemplate.convertAndSend("kafkaChannel", message); 16 return "send2 success"; 17 } 18 }
4、实现消息消费者：
1 @Component 2 public class RedisSubscriber extends MessageListenerAdapter { 3 4 @Override 5 public void onMessage(Message message, byte[] pattern) { 6 System.out.println(message); 7 } 8 }
5、配置消费者连接的Bean：
1 @Bean 2 public RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory, 3 MessageListenerAdapter listenerAdapter) { 4 RedisMessageListenerContainer container = new RedisMessageListenerContainer(); 5 container.setConnectionFactory(connectionFactory); 6 container.addMessageListener(listenerAdapter, new PatternTopic("TextChannel")); 7 container.addMessageListener(listenerAdapter, new PatternTopic("kafkaChannel"));//配置要订阅的订阅项 8 return container; 9 }
6、测试：
http://localhost:8080/send1?message=111111 http://localhost:8080/send2?message=2222222
