com.mchange.v2.resourcepool.CannotAcquireResourceException: A ResourcePool could

Spring结合c3p0的时候,出现如下异常:

 

com.mchange.v2.resourcepool.CannotAcquireResourceException: A ResourcePool could not acquire a resource from its primary factory or source.

 

结果发现问题出在这里:

 

    jdbc:mysql://localhost:3306/db_temp?useUnicode=true&characterEncoding=utf-8
   

 

后来改成:

 

   jdbc:mysql://localhost:3306/db_temp?useUnicode=true&characterEncoding=utf-8

 

不应该分行,否则出现异常.
