java.sql.SQLException: QueryRunner requires a DataSource to be invoked in this way, or a Connection

阿新 • • 發佈：2019-01-23

我在使用org.apache.commons.dbutils和c3p0操作資料庫時，報的錯，翻譯過來就是：

QueryRunner需要以這種方式呼叫資料來源，或者需要傳遞連線

排查：

1、是否有資料來源，即是否正常載入c3p0-config.xml檔案。

2、資料來源是否傳遞給連線池。

最後，發現是在例項化QueryRunner時，未將ComboPooledDataSource物件傳遞給它。更正後程式碼入下：

private QueryRunner qr = new TxQueryRunner(JdbcC3P0Utils.getDataSource());

TxQueryRunner是我對QueryRunner的重寫類。

按照黑馬的視訊學習做專案，第一步搭建環境時候。寫好JdbcUtils，測試是否能連線資料庫時候。發現一執行main方法，程式就卡住了，接著就會出以下這2個錯誤：（main方法裡是想輸出 getConnection方法的返回值，也就是connection的雜湊值，這樣就代表獲取連線成功了。

JDBC報錯java.sql.SQLException: Cannot convert value '0000-00-00 00:00:00' from column 14 to T

出現這個錯誤的原因是：當資料庫中的Date型別欄位值是 ‘0000-00-00’時，JDBC不能把’0000-00-00’轉化為一個java.sql.Date 問題的解決方案是在連線資料庫的url後加入?zeroDateTimeBehavior=convertToNull 如：

java.sql.SQLException: Cannot convert value '0000-00-00 00:00:00' from column 7 to TIMESTAMP

在Mysql資料庫中使用DATETIME型別來儲存時間，使用JDBC中讀取這個欄位的時候，應該使用 ResultSet.getTimestamp()，這樣會得到一個java.sql.Timestamp型別的資料。在這裡既不能使用 ResultSet.getDate()，也不能使用ResultSet.
