java - 使用c3p0时出现一个问题，使得项目老是挂掉、( ˇˍˇ )

Question

框架是spring Struts2 mybatis
报错信息如下

是配置的问题？可是同一套配置在多个不同的平台一起运行着啊，只有其中一个会挂掉、、、

Answer 1

Change the value of jdbc.breakAfterAcquireFailure = true in the configuration to false

Answer 2

Is the pressure experienced by each configuration different? Is there a big difference in database configuration? These will all affect the connection pool. I recommend you a connection pool druid that can monitor SQL.
