我在应用程序中使用了JPA和HikariCP。在那里，我可以监视与JPA相关的内容，但无法激活和使用JDBC连接。
我尝试在persistense.xml中使用此属性
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

<property name="hibernate.connection.provider_class" value="org.hibernate.hikaricp.internal.HikariCPConnectionProvider"/>
</properties>
</persistence-unit>
</persistence>
正在给出此例外。我无法在javamelody图上看到有关活动和已使用连接的任何信息。

我也尝试了上述简单的休眠属性，但这也给了例外。
