关于JFinal的c3p0配置，是否只开放5个参数配置？ ： 配置报错
@JFinal 你好，想跟你请教个问题：正式环境发现c3p0的死锁问题，查阅相关资料，想修改c3p0的设置，但是在Jfinal的c3p0插件中，只发现了maxPoolSize、minPoolSize、initialPoolSize、maxIdleTime、acquireIncrement这五个参数，是否不能配置其它参数？ -------附带c3p0的异常日志------- 12:13:31,948 WARN com.mchange.v2.async.ThreadPoolAsynchronousRunner.run():624 - com.mchange.v2.async.ThreadPoolAsynchronousRunner$DeadlockDetector@2804047 -- APPARENT DEADLOCK!!!

换上 druid plugin 即可， c3p0 太老了， 在 jfinal 官网首页下载 jfinal demo，里头有现成的使用 DruidPlugin 的实例
