com.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@4e47db1f -- Acquisition Attempt Failed!!!
在maven中spring配置c3p0遇到的问题，其它地方遇到解决思路一致，以下：mysql 1.检查四个参数是否有问题，注意大小写 2.检查数据库是否开启 3.检查是否导入了mysql-connector-jar包 4.检查mysql-connector-jar的jar包版本是否和数据库版本一致 列如我用的数据库的版本是8.0.12，那么对应的mysql-connector-ja的版本应该为8.
