Hikari连接泄漏错误

Question

我已经用java配置实现了Hikari连接，代码如下，

HikariConfig sqlConfig = new HikariConfig();
sqlConfig.setDataSourceClassName(WebAppListener.getContextParameter(DB_DRIVER_STRING));
                sqlConfig.addDataSourceProperty("url", WebAppListener.getContextParameter(DB_CONNECTION_STRING));
                sqlConfig.addDataSourceProperty("user", WebAppListener.getContextParameter(DB_USER_NAME));
                sqlConfig.addDataSourceProperty("password", WebAppListener.getContextParameter(DB_PASSWORD));
                sqlConfig.setLeakDetectionThreshold(TimeUnit.SECONDS.toMillis(30));
                sqlConfig.setValidationTimeout(TimeUnit.MINUTES.toMillis(1)); 
                sqlConfig.setMaximumPoolSize(POOL_SIZE);
                sqlConfig.setMinimumIdle(0);
                sqlConfig.setMaxLifetime(TimeUnit.MINUTES.toMillis(2)); // 120 seconds

                sqlConfig.setIdleTimeout(TimeUnit.MINUTES.toMillis(1)); // minutes
                sqlConfig.setConnectionTimeout(TimeUnit.MINUTES.toMillis(5));
                sqlConfig.setPoolName(POOL_NAME);
                sqlConfig.setAutoCommit(true);
                sqlConfig.setInitializationFailFast(false);

                dataSource = new HikariDataSource(sqlConfig);

                sqlConfig.setConnectionTestQuery("/* ping */ SELECT 1");
                if (null != connection) {
                    log.info("webAppListener.java :Hikari ::NEW Connection successful! : " + connection.hashCode());
                }
                else {
                    connection = dataSource.getConnection();
                }

但是当我部署我的应用程序时，它会提供这种日志：

我的应用程序在开发服务器上没有任何中断的情况下运行，请帮助我，我在互联网上搜索但我没有得到任何解决方案。
