maxIdleTime： 最大空閒時間,60秒內未使用則連接被丟棄。若爲0則永不丟棄。Default: 0 acquireIncrement： 當連接池中的連接耗盡的時候c3p0一次同時獲取的連接數。Default: 3 maxStatements： JDBC的標準參數，用以控制數據源內加載的PreparedStatements數量。但由於預緩存的statements 屬於單個connection而不是整個連接池。所以設置這個參數需要考慮到多方面的因素。 如果maxStatements與maxStatementsPerConnection均爲0，則緩存被關閉。Default: 0 idleConnectionTestPeriod： 每60秒檢查所有連接池中的空閒連接。Default: 0 acquireRetryAttempts： 定義在從數據庫獲取新連接失敗後重復嘗試的次數。Default: 30 breakAfterAcquireFailure: 獲取連接失敗將會引起所有等待連接池來獲取連接的線程拋出異常。但是數據源仍有效 保留，並在下次調用getConnection()的時候繼續嘗試獲取連接。如果設爲true，那麼在嘗試 獲取連接失敗後該數據源將申明已斷開並永久關閉。Default: false testConnectionOnCheckout： 因性能消耗大請只在需要的時候使用它。如果設爲true那麼在每個connection提交的 時候都將校驗其有效性。建議使用idleConnectionTestPeriod或automaticTestTable 等方法來提升連接測試的性能。Default: false -->
