org.hibernate.exception.GenericJDBCException：無法提取ResultSet

Question

嗨，您能幫我解決這個問題嗎？ 我在MySQL DB中連接了此應用程序，每次運行此作業以從DB中獲取數據時，我總是會收到此異常，請參閱添加了java類，DAO和方法以及Apache DBCP2配置的完整堆棧跟蹤。

我在java.sql.SQLException中遇到了相同的錯誤：表太多； MySQL在一個聯接中只能使用61個表

發生這種情況是因為關聯了太多的表。如果不使用提取類型，則可能是由於關聯而發生的。

例如-在我的情況下，我有150多個表Book_Selling，Refund等。在這種情況下，我創建了一個表來連接所有與付款有關的表。如果我從付款表中獲取數據，則它會連接所有其他表及其相關表，因此所有這些表的數量超過61個表。 在mysql默認情況下，您一次只能使用61個表創建聯接查詢

使用fetch type作為lazy可以解決您的問題。
