HikariConnectionProvider部署到JBoss应用服务器7.1时发生ClassNotFoundException

Question

我构建了一个DAL jar库，它使用HikariCP作为连接提供者。这个jar然后被包含（作为一个Maven依赖）在一个web应用程序中。

我将此Web应用程序测试到Wildfly 8.0.0应用程序服务器上，并且所有工作均如预期：部署过程无任何问题，我可以使用Web应用程序访问数据库。

当我运行相同的 Web应用程序到JBoss应用程序服务器7.1上时，问题就出现了。事实上，在部署过程以下情况例外结束堆栈

这里是在DAL

这里confgured的persistence.xml是DAL的pom.xml

你认为这个问题可能是什么？这是一个已知的HikariCP问题吗？ JBoss AS 7.1支持HikariCP吗？

谢谢 最好的问候

Answer 1

HikariCP无法加载，因为该类org.hibernate.engine.jdbc.connections.spi.ConnectionProvider找不到，至少根据堆栈跟踪。我会验证Hibernate是正确的版本（与Wildfly中使用的版本相同）。另外，请注意Hibernate现在包含他们自己的HikariConnectionProvider，所以我建议切换到那个。
