我故意断开了连接，导致连接超时，但是我从未从hikari收到泄漏检测阈值错误。我尝试将LeakDetectionthreshold值设置为最小可能的2000。公制注册表运行正常。发生了什么？另外，我在以下地方读到了
应该每30秒给出一次hikari日志。我只有在应用程序启动时才能看到这一点。
这是我设置值的方式：
`
if (ds == null || ds.isClosed()) {
//after setting up basic ones
config.addDataSourceProperty("autoReconnect", true);
config.setLeakDetectionThreshold(15000);
config.setMetricRegistry(ApplicationUtils.getMetricRegistry());
config.setPoolName("MySQLConnectionPool");
ds = new HikariDataSource(config);
LOGGER.info("Created DS in MySQL", ds);
}`
完全没有Hikari管家的日志。看起来好像没有运行
