我正在使用播放框架,我想连接数据库,但我不能,因为我收到以下错误:

play.api.Configuration$$anon$1: Configuration error[Cannot connect to database [default]]
Caused by: play.api.Configuration$$anon$1: Configuration error[Failed to initialize pool: Unknown system variable 'tx_isolation']
Caused by: com.zaxxer.hikari.pool.HikariPool$PoolInitializationException: Failed to initialize pool: Unknown system variable 'tx_isolation' java.sql.SQLException: Unknown system variable 'tx_isolation

我试图找到tx_isolation,但它不存在:

mysql> show variables like 'tx_isolation';
Empty set (0.00 sec)

那么我能找到什么,怎样才能找到tx_isolation？

抱歉.这是我的错误代码.我使用mysql 8.0.11.所以我找到'transaction_isolation'

play.db {
  config = "db"
  default = "default"
}
db {
//TODO : ????
  default.driver = com.mysql.jdbc.Driver
  default.url = "jdbc:mysql://127.0.0.1:3306/testPlayDB"
  default.username = root
  default.password = "321A@654"
} …
