Exception during pool initialization

"Exception during pool initialization"是一个错误，通常出现在使用HikariPool-1连接池时。这个错误意味着在连接池的初始化过程中发生了异常。根据引用提供的解决方法，我们可以尝试以下步骤来解决这个问题：

1. 检查数据库连接配置：确保数据库连接的URL、用户名和密码等配置信息正确无误，并且与数据库服务器的配置匹配。

2. 检查数据库服务器状态：确保数据库服务器正在运行，并且可以通过网络访问。

3. 检查连接池配置：检查连接池的配置参数是否正确，例如最大连接数、最小空闲连接数等。确保这些参数的设置符合应用程序的需求。

4. 检查数据库驱动程序：确保使用的数据库驱动程序版本与连接池的要求兼容。尝试更新或更换数据库驱动程序版本。

5. 检查网络连接：如果应用程序和数据库服务器之间存在网络隔离或防火墙等限制，则需要确保网络连接正常。可以尝试使用telnet等工具测试与数据库服务器的连接。

6. 查看错误日志：查看应用程序的错误日志，寻找更详细的错误信息。根据错误信息进行排查和调试。
