我有一个独立的JPA(Hibernate) - MySQL应用程序。
我的persistence.xml看起来像:
<persistence-unit name="JPAProj" transaction-type="RESOURCE_LOCAL">
<!-- Persistence provider -->
<provider>
org.hibernate.ejb.HibernatePersistence
</provider>
....
<properties>
<property name='hibernate.show_sql' value='true'/>
<property name='hibernate.format_sql' value='true'/>
<property name='hibernate.dialect' value='org.hibernate.dialect.MySQL5InnoDBDialect'/>
<property name='hibernate.hbm2ddl.auto' value='update'/>
<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
<property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost/classicmodels"/>
<property name="javax.persistence.jdbc.user" value="someuser"/>
<property name="javax.persistence.jdbc.password" value=""/>
</properties>
</persistence-unit>
我想在此应用程序中使用连接池(比如Apache DBCP),我需要对persistence.xml进行哪些更改?
