部署到HikariConnectionProvider应用服务器7.1时的ClassNotFoundException

Question

我构建了一个DAL库，它使用HikariCP作为连接提供程序。然后将此jar (作为Maven依赖项)包含在web应用程序中。

我在Wildfli8.0.0应用服务器上测试了这个web应用程序，所有这些都按预期的方式工作:部署过程结束时没有问题，我可以使用web应用程序访问DB。

当我在应用服务器7.1上运行相同的 web应用程序时，就会出现这个问题。实际上，部署过程以以下异常堆栈结束

这是在DAL中混合的persistence.xml

你认为问题会是什么？这是一个已知的HikariCP问题吗？HikariCP在JBoss中是否支持7.1？

谢谢，致以最良好的问候

Answer 1

HikariCP未能加载，因为无法找到类org.hibernate.engine.jdbc.connections.spi.ConnectionProvider，至少根据堆栈跟踪。我将验证Hibernate是正确的版本(与Wildfly中使用的版本相同)。另外，注意Hibernate现在包括了他们自己的HikariConnectionProvider，所以我建议切换到那个。
