本文记录了一个关于使用HikariCP连接池在初始化过程中遇到的MySQL通讯失败错误，具体表现为在尝试建立与数据库服务器的连接时，驱动未能接收到服务器的响应包，导致连接池初始化失败。

2018-06-27 14:12:28.804 ERROR 14312 --- [ restartedMain] com.zaxxer.hikari.pool.HikariPool : HikariPool-1 - Exception during pool initialization.

com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
