我正在使用spring一個Hibernate，這裏是Hibernate.properties 問題是Connection提供程序不會更改爲c3p0ConnectionProvider，即使有c3p0 settings.THey只是加載，似乎沒有做任何事情跟他們。c3p0連接提供程序未設置
hibernate.show_sql=true
hibernate.hbm2ddl.auto=validate
hibernate.c3p0.testConnectionOnCheckin = true
hibernate.c3p0.checkoutTimeout = 0
hibernate.c3p0.acquireIncrement=5
hibernate.c3p0.idleConnectionTestPeriod=3000
hibernate.c3p0.initialPoolSize=10
hibernate.c3p0.maxIdleTime=300
hibernate.c3p0.maxPoolSize=50
hibernate.c3p0.maxStatements=100
hibernate.c3p0.minPoolSize=5
hibernate.c3p0.testConnectionsOnCheckout=true
這是堆棧跟蹤。

在Hibernate.properties中，首先選取兩行（hibernate.show_sql = true hibernate.hbm2ddl.auto = validate），但其餘部分不會。 – icedek
