У меня есть приложение Spring / JPA с Hibernate в качестве поставщика JPA. Я настроил источник данных C3P0 в Spring через:

<bean id="myJdbcDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
      destroy-method="close">
  <!-- Connection properties -->
  <property name="driverClass" value="$DS{database.class}" />
  <property name="jdbcUrl" value="$DS{database.url}" />
  <property name="user" value="$DS{database.username}" />
  <property name="password" value="$DS{database.password}" />
  <!-- Pool properties -->
  <property name="minPoolSize" value="5" />
  <property name="maxPoolSize" value="20" />
  <property name="maxStatements" value="50" />
  <property name="idleConnectionTestPeriod" value="3000" />
  <property name="loginTimeout" value="300" />

Затем я указал этот источник данных в фабрике диспетчера сущностей Spring следующим образом:

<bean id="myLocalEmf"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
      <property name="persistenceUnitName" value="myapp-core" />
      <property name="dataSource" ref="myJdbcDataSource" />
 </bean>


However, I recently noticed while browsing maven artifacts a "hibernate-c3p0". What is this? Is this something I need to use? Or do I already have this configured properly?
