Question

我确实按照搜索8.2.2持久性单位范围中的规格进行了跟踪，但它没有像

那样抛出异常

15:08:09,956 WARNING [FileZippedJarVisitor] Unable to find file (ignored): file:entities1.jar
java.io.FileNotFoundException: entities1.jar (The system cannot find the file specified)
...similarly other one too

这是耳朵的结构：

    |-ear--
           |-lib--|... some libs ...
           |      |--my-persistence-xml.jar
              |--entities1.jar
              |--entities2.jar

           |-ejb-1.jar
           |-web-1.war

这是持久性：

    <persistence-unit name="pu" transaction-type="JTA">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:/mypu</jta-data-source>
        <jar-file>entities1.jar</jar-file>
        <jar-file>entities2.jar</jar-file>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
            <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
            <property name="hibernate.show_sql" value="true"/>
            <property name="hibernate.format_sql" value="true" />
        </properties>
     </persistence-unit>

Answer 1

persistence.xml应放在META-INF模块的ejb-jar文件夹中。在这种情况下，您可以使用persistence.xml而不使用<jar-file>。所有的entites将自动注册。

如果您想使用<jar-file>，则路径应为

<jar-file>../../entities1.jar</jar-file>
<jar-file>../../entities2.jar</jar-file>

my-persistence-xml.jar的含义。这是jar或xml？

持久性范围失败？
