jar-file你可以使用
persistence.xml
<persistence> <persistence-unit name="OrderManagement"> <description>This unit manages orders and customers. It does not rely on any vendor-specific features and can therefore be deployed to any persistence provider. </description> <jta-data-source>jdbc/MyOrderDB</jta-data-source> <jar-file>MyOrderApp.jar</jar-file> <class>com.widgets.Order</class> <class>com.widgets.Customer</class> </persistence-unit></persistence>
该文件定义了一个名为的持久性单元
OrderManagement，它使用JTA感知数据源
jdbc/MyOrderDB。所述
jar-file和
class元素指定管持久类：实体类，可嵌入类和超类映射。该
jar-file元素指定JAR文件都包含持久化类管理的打包持久单元可见，而该class元素明确命名持久化类管理。
对于
Hibernate，也可以进行设置和配置以获取更多详细信息。
编辑：实际上，如果你不介意不符合规范，
Hibernate即使在Java SE中也支持自动检测。为此，添加
hibernate.archive.autodetection属性：
<persistence-unit name="eventractor" transaction-type="RESOURCE_LOCAL"> <!-- This is required to be spec compliant, Hibernate however supports auto-detection even in JSE. <class>pl.michalmech.eventractor.domain.User</class> <class>pl.michalmech.eventractor.domain.Address</class> <class>pl.michalmech.eventractor.domain.City</class> <class>pl.michalmech.eventractor.domain.Country</class> --> <properties> <!-- Scan for annotated classes and Hibernate mapping XML files --> <property name="hibernate.archive.autodetection" value="class, hbm"/> <property name="hibernate.hbm2ddl.auto" value="validate" /> <property name="hibernate.show_sql" value="true" /> </properties></persistence-unit>
