HikariConnectionProvider部署到JBoss應用服務器7.1時發生ClassNotFoundException

Question

我構建了一個DAL jar庫，它使用HikariCP作爲連接提供者。這個jar然後被包含（作爲一個Maven依賴）在一個web應用程序中。

我將此Web應用程序測試到Wildfly 8.0.0應用程序服務器上，並且所有工作均如預期：部署過程無任何問題，我可以使用Web應用程序訪問數據庫。

當我運行相同的 Web應用程序到JBoss應用程序服務器7.1上時，問題就出現了。事實上，在部署過程以下情況例外結束堆棧

這裏是在DAL

你認爲這個問題可能是什麼？這是一個已知的HikariCP問題嗎？ JBoss AS 7.1支持HikariCP嗎？

謝謝 最好的問候

Answer 1

HikariCP無法加載，因爲該類org.hibernate.engine.jdbc.connections.spi.ConnectionProvider找不到，至少根據堆棧跟蹤。我會驗證Hibernate是正確的版本（與Wildfly中使用的版本相同）。另外，請注意Hibernate現在包含他們自己的HikariConnectionProvider，所以我建議切換到那個。
