JedisPool Bean 등록 에러

jedis bean 등록 이후 connection pool 설정을 하려했을때 발생한 문제

이전에 설정했던 jedis bean

문제가된 코드

문제가된 Bean : @Bean(“myJedisPool”)

@Slf4j
@Configuration
public class MyRedisConfig {

  @Value("${data.redis.host}")
  private String HOST;

  @Value("${data.redis.port}")
  private int PORT;

  @Value("${data.redis.maxTotal}")
  private int MAX_TOTAL;

  @Value("${data.redis.maxIdle}")
  private int MAX_IDLE;

  @Value("${data.redis.minIdle}")
  private int MIN_IDLE;

  @Value("${data.redis.maxWaitMillis}")
  private long MAX_WAIT_MILLIS;

  @Bean("myJedisPool")
  public JedisPool myJedisPool() {
    JedisPoolConfig poolConfig = new JedisPoolConfig();
    poolConfig.setMaxTotal(MAX_TOTAL);
    poolConfig.setMaxIdle(MAX_IDLE);
    poolConfig.setMinIdle(MIN_IDLE);
    poolConfig.setMaxWaitMillis(MAX_WAIT_MILLIS);

    try {
      return new JedisPool(poolConfig, HOST, PORT);
    } catch (Exception e) {
      log.error("Error initializing Jedis pool", e);
      return null;
    }
  }

    } catch (JedisException jedisException) {
      log.error("jedis bean registration fail", jedisException);
      return null;
    }

어떤 이유인지는 몰라도 해당 부분에서 MXbean에 이미 등록되었다고 나옴 실제로 디버깅을 해보니 multiname이 null 로 들어가 발생

해결 방법 : 여러 사이트를 돌아다니면서 테스트를 해보았으나
결국, JMX를 이용한 JedisPool 모니터링을 포기하고 해당 코드 추가 : poolConfig.setJmxEnabled(false);

@Bean("myJedisPool")
public JedisPool myJedisPool() {
  JedisPoolConfig poolConfig = new JedisPoolConfig();
  poolConfig.setJmxEnabled(false);
  poolConfig.setMaxTotal(MAX_TOTAL);
  poolConfig.setMaxIdle(MAX_IDLE);
  poolConfig.setMinIdle(MIN_IDLE);
  poolConfig.setMaxWaitMillis(MAX_WAIT_MILLIS);

  try {
    return new JedisPool(poolConfig, HOST, PORT);
  } catch (Exception e) {
    log.error("Error initializing Jedis pool", e);
    return null;
  }
}
