我的hikari-cp出现连接泄漏错误。当连接达到最大大小时，我的程序没有连接错误。
我的配置；

Properties properties = new Properties();
properties.put("hibernate.connection.url", connectionURL(provider));
                    properties.put("hibernate.connection.username", provider.getProductionUserName());
                    properties.put("hibernate.connection.password", provider.getProductionPassword());

                    properties.put("hibernate.connection.provider_class", "org.hibernate.hikaricp.internal.HikariCPConnectionProvider");
                    properties.put("hibernate.hikari.poolName", "SerasCP");
                    properties.put("hibernate.hikari.minimumIdle" , "20");
                    properties.put("hibernate.hikari.maximumPoolSize", "40");
                    properties.put("hibernate.hikari.idleTimeout", "6000");
                    properties.put("hibernate.hikari.maxLifetime", "0");
                    properties.put("hibernate.hikari.connectionTimeout", "300000");
                    properties.put("hibernate.hikari.leakDetectionThreshold", "2100000");
                    properties.put("logging.level.com.zaxxer.hikari.HikariConfig", "INFO");
                    properties.put("logging.level.com.zaxxer.hikari", "TRACE");
                    properties.put("hibernate.hikari.connectionTestQuery", "SELECT GETDATE()");
