我正在使用 spring 一个 Hibernate，这里是 Hibernate.properties 问题是即使有 c3p0 设置，连接提供程序也不会更改为 c3p0ConnectionProvider。它们只是被加载，似乎什么也没做。
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
这是堆栈跟踪。
