在下面的配置中,如果我错过了初始,最大,最小池大小. c3p0中的默认连接池大小是多少？
<bean class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close" id="dataSource">
<property name="driverClass" value="${dbDriver}"/>
<property name="jdbcUrl" value="${dbURL}"/>
<property name="user" value="${dbUsername}"/>
<property name="password" value="${dbPassword}"/>
<property name="initialPoolSize" value="5"/>
<property name="maxPoolSize" value="50"/>
<property name="minPoolSize" value="5"/>
<property name="maxIdleTime" value="3000"/>
</bean>
解决方法
The InitialPoolSize is 3 by default.
