spring hikaricp的连接没有立即关闭

我在用hikaricp。
如果我打电话给 use 方法在maeildbservice类中执行3次（maximumpoolsize），下次执行时超时。 MaeilHikariCP - Connection is not available, request timed out after 30001ms. （更详细的错误信息在末尾）
我认为连接池的所有连接都被使用了，即使我调用了close（）。如何立即将这些连接返回到连接池？
（+）我也在使用 @Transactional 注解超出 use 方法。我在同一个过程中使用了springjpa（mysql）和oracle。

        config.setUsername("hr");

hikaricp几乎立即关闭连接！

我只是在某些情况下抛出错误时没有关闭连接。完全是我的错。检查你的连接，结果集，语句在任何情况下都关闭良好。

public MaeilDBDto.MaeilMiCatsResponse use(String loginId, String productOcrCode) {
        Connection connection = MaeilDataSource.getConnection();
        MaeilDBDto.MaeilMiCatsResponse response;
        try {
            response = getCodeState(connection, productOcrCode); <-- can throw exception
            use(connection, productOcrCode); <-- can throw exception
        } finally {
            MaeilDataSource.close(connection); // <-- I added this.
        }

        return response;
    }
