Hibernate 无法识别来自 persistence.xml 的 DBCP 连接池配置

Question

我想在 SE 环境中使用来自 Apache commons 的 DBCP2 连接池：(build.gradle)

compile group: 'org.apache.commons', name: 'commons-dbcp2', version: '2.2.0'

persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>
<persistence 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"
         version="2.1">

<persistence-unit name="MyPersistenceUnit" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <class>com.myapp.MyModel</class>
    <properties>
        <property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver"/>
        <property name="javax.persistence.jdbc.url" value="jdbc:postgresql://localhost:5432/my_db"/>
        <property name="javax.persistence.jdbc.user" value="postgres"/>
        <property name="javax.persistence.jdbc.password" value="mypassword"/>

        <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQL94Dialect"/>
        <property name="hibernate.hbm2ddl.auto" value="validate"/>

        <property name="hibernate.dbcp.initialSize" value="5"/>
        <property name="hibernate.dbcp.maxTotal" value="20"/>
        <property name="hibernate.dbcp.maxIdle" value="10"/>
        <property name="hibernate.dbcp.minIdle" value="5"/>
        <property name="hibernate.dbcp.maxWaitMillis" value="-1"/>

        <property name="hibernate.show_sql" value="true"/>
        <property name="hibernate.format_sql" value="true"/>
    </properties>
</persistence-unit>

但是 Hibernate 不承认这一点，仍然使用它内置的连接池：

WARN  org.hibernate.orm.connections.pooling - HHH10001002: Using Hibernate built-in connection pool (not for production use!)

喜欢coladict mentioned in his ,

Hibernate does not support automatic configuration for Apache commons dbcp2.

支持

C3P0, Proxool and Hikari. They are checked in that order.

Hibernate does not recognize DBCP connection pool configurations from persistence.xml
