我正在使用src / main / resources / META-INF / persistence.xml中的persistence.xml开发Hibernate JPA持久性Web应用程序（在war文件中，它位于WEB-INF / classes / META-INF中）。这一切都适用于本地Tomcat服务器，但是当放在Openshift JBoss EWS上时，在启动时收到此消息：

Persistence.xml以
开头<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">
并且有两个持久性单元。我还删除了hibernate.cfg.xml，这些都是在其他SO答案中提出的。谁知道我在这里做错了什么？
答案 0 :(得分：0)
知道了。
问题是我使用Persistence.createEntityManagerFactory("unit")来创建EntityManagerFactory并将其注入其他Spring bean。
现在我把
<bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="unit" />
</bean>
直接在applicationContext.xml中。 仍然没有解释以前的方法有什么问题，但它确实有效。
