Java Hikari无法创建池连接

我需要实现与Hikari库的JDBC池连接，但我无法让它工作。我的代码如下：

public class DataSource {

    private static HikariConfig config = new HikariConfig();
    private static HikariDataSource ds;
    static {
        config.setJdbcUrl("jdbc:sqlserver://localhost:1433;database=Test;integratedSecurity=true;");
        config.setUsername("****");
        config.setPassword("*********");
        config.addDataSourceProperty("cachePrepStmts", "true");
        config.addDataSourceProperty("prepStmtCacheSize", "250");
        config.addDataSourceProperty("prepStmtCacheSqlLimit", "2048");
        ds = new HikariDataSource(config);
        ds.setMaximumPoolSize(100);
        ds.setMinimumIdle(5);
    }
    private DataSource() {
    }

    public static Connection getConnection() throws SQLException {
        HikariPool hikariPool = new HikariPool(config);
        System.out.println("POOL Active Connections -- " + hikariPool.getActiveConnections() + " Total " + hikariPool.getTotalConnections());
        return ds.getConnection();
    }

}

当我询问活动连接的数量时。它总是以1个活动连接进行响应

您能告诉我一些解决此问题的方法吗？

是否可能只有1个活动连接和5个空闲连接？您只发出一个请求，重用一个连接而不是其他连接是有意义的，特别是在单线程环境中。您在每次调用时都要创建一个新的配置，请参阅静态配置。我试图在Hikari中复制许多连接，但我做不到。你有没有任何例子可以让我看看Hikari如何生成许多活动连接？你读过我之前的评论吗？是否引用静态变量HikariConfig而不是每次调用时创建的本地HikariConfig？HikariPool*需要创建HikariPool一次。

    private static final Logger logger = LoggerFactory.getLogger(MainSample.class);

        Class.forName(driverClassName);
    }

    public static void main(String [] args) throws SQLException, ClassNotFoundException {

        executor.submit(() -> {
            String threadName = Thread.currentThread().getName();
            System.out.println("POOL " + threadName);
            try {
                fechData();
            } catch (SQLException e) {
