篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了create connection error, url: jdbc:mysql://**ip**:3306/*?errorCode 1045, state 28000相关的知识,希望对你有一定的参考价值。

运行项目时,在登录页面输入账号密码后,控制台报数据库错误,排查了好久发现数据库的账号密码写错了,改正后就可以了。

之后又报数据库初始化错误:

1  init datasource error 
2 The last packet sent successfully to the server was 0 milliseconds ago. 
3 The driver has not received any packets from the server.

回来查资料,在项目的配置文件mysql.url后面添加参数

&autoReconnect=true&failOverReadOnly=false&maxReconnects=10

再运行就可以了,没有报错。不过还是没有找到原因。
