<!--
ComboPooledDataSource 参数说明

maxIdleTime：
最大空闲时间,60秒内未使用则连接被丢弃。若为0则永不丢弃。Default: 0
acquireIncrement：
当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。Default: 3
maxStatements：
JDBC的标准参数，用以控制数据源内加载的PreparedStatements数量。但由于预缓存的statements
属于单个connection而不是整个连接池。所以设置这个参数需要考虑到多方面的因素。
如果maxStatements与maxStatementsPerConnection均为0，则缓存被关闭。Default: 0
idleConnectionTestPeriod：
每60秒检查所有连接池中的空闲连接。Default: 0
acquireRetryAttempts：
定义在从数据库获取新连接失败后重复尝试的次数。Default: 30
breakAfterAcquireFailure:
获取连接失败将会引起所有等待连接池来获取连接的线程抛出异常。但是数据源仍有效
保留，并在下次调用getConnection()的时候继续尝试获取连接。如果设为true，那么在尝试
获取连接失败后该数据源将申明已断开并永久关闭。Default: false
testConnectionOnCheckout：
因性能消耗大请只在需要的时候使用它。如果设为true那么在每个connection提交的
时候都将校验其有效性。建议使用idleConnectionTestPeriod或automaticTestTable
等方法来提升连接测试的性能。Default: false
