springboot 线程池实现redis订阅异步处理消息

Spring Boot 中可以利用 Spring 的 `ThreadPoolTaskExecutor` 或者第三方库如 `Spring Cloud Task` 实现 Redis 订阅异步处理消息。以下是基本步骤： 1. 配置 ThreadPoolTaskExecutor 或创建一个自定义线程池： ```java @Bean public ThreadPoolTaskExecutor redisThreadPoolExecutor() { ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor(); executor.setCorePoolSize(5); // 核心线程数 executor.setMaxPoolSize(10); // 最大线程数 executor.setQueueCapacity(100); // 队列容量 executor.setThreadNamePrefix("redis-async-task-"); executor.initialize(); return executor; } ``` 2. 创建一个 Runnable 接口实现类，用于处理 Redis 的消息： ```java public class RedisMessageHandler implements Runnable { private final String channel; private final RedisTemplate<String, Object> redisTemplate; public RedisMessageHandler(String channel, RedisTemplate<String, Object> redisTemplate) { this.channel = channel; this.redisTemplate = redisTemplate; } @Override public void run() { List<String> messages = redisTemplate.opsForSubscription().subscribe(channel); for (String message : messages) { handleMessage(message); } } // 处理接收到的消息逻辑 private void handleMessage(String message) { // ... your handling logic here } } ``` 3. 异步监听 Redis 更新并发送到线程池执行： ```java @EventListener public void onRedisMessage(RedisMessageEvent event) { String channel = event.getChannel(); // 获取频道名 redisThreadPoolExecutor().execute(new RedisMessageHandler(channel, context.getBean(RedisTemplate.class))); } ``` 4.
