springboot 使用zookeeper实现分布式队列的基本步骤

</dependency>

zookeeper.connectionString=localhost:2181

@Configuration
public class DistributedQueueConfig {
    @Value("${zookeeper.connectionString}")
    private String connectionString;
    @Bean
    public DistributedQueue<String> distributedQueue() throws Exception {
        RetryPolicy retryPolicy = new ExponentialBackoffRetry(1000, 3);
        CuratorFramework curatorFramework = CuratorFrameworkFactory.newClient(connectionString, retryPolicy);
        curatorFramework.start();
        DistributedQueue<String> distributedQueue = QueueBuilder.builder(curatorFramework, new QueueConsumer<String>() {
            @Override
            public void consumeMessage(String message) throws Exception {
                // 处理队列中的消息
            }
            @Override
            public void stateChanged(CuratorFramework client, ConnectionState newState) {
                // 处理连接状态变化
            }
        }, new QueueSerializer<String>() {
            @Override
            public byte[] serialize(String item) {
                return item.getBytes();
            }
            @Override
            public String deserialize(byte[] bytes) {
                return new String(bytes);
            }
        }, "/queue").buildQueue();
        distributedQueue.start();
        return distributedQueue;
    }
}

@Autowired
private DistributedQueue<String> distributedQueue;
public void addToQueue(String message) throws Exception {
    distributedQueue.put(message);
