连接池配置
#default : 0
#配置当连接池所有连接用完时应用程序getConnection的等待时间。为0则无限等待直至有其他连接释放
#或者创建新的连接,不为0则当时间到的时候如果仍没有获得连接,则会抛出SQLException
checkout.timeout=600000
#当连接池中的连接用完时,C3P0一次性创建新连接的数目 default : 3
acquireIncrement=20
#用来配置测试连接
preferredTestQuery=select 1 from dual
#如果为true,则在close的时候测试连接的有效性
testConnectionOnCheckin=false
#用来配置测试空闲连接的间隔时间,测试方式:preferredTestQuery或者automaticTestTable
idleConnectionTestPeriod=3000000
#连接池在获得新连接失败时重试的次数,如果小于等于0则无限重试直至连接获得成功
acquireRetryAttempts=0
#default : 1000ms
#连接池在获得新连接时的间隔时间 default : 1000 单位ms
acquireRetryDelay=1000
