我正在JBOSS EAP 6.2中開發和部署RESTful服務。對於這個任務，我使用CXF，Spring和Embedded Derby來存儲數據。 我花了幾個小時試圖調試這個錯誤，但無法實現它。我已經多次檢查過數據庫是完全空的，沒有任何表。但我總是收到相同的堆棧跟蹤。 我也讀過類似的問題，但這也沒有幫助。 所以，這裏是代碼：java.sql.SQLException：Schema'APP'中已存在表/視圖'LOCATION'

您是第一次調用REST服務還是僅在下一次調用時出現此錯誤？ – aribeiro
它顯示我每次啓動部署了該服務的JBoss。 – Kelper
是什麼讓你覺得這個表不存在？這個例外非常清楚地表明：「表格/視圖'LOCATION'已經存在於模式'APP'中。」你只需要創建表格一次;在此之後，表格會一直存在，直到您「DROP TABLE」或銷燬整個數據庫。 –
