【问题描述】：
我正在尝试使用 spring data jpa 部署 Spring boot 并休眠到 Oracle Weblogic 12c (12.2.1)，具有以下依赖项并低于异常。
- JDK 8
- Weblogic 12.2.1
- Spring Boot 1.4.1 版
- Spring 数据 jpa 版本 1.10.3
- Spring orm 4.3.3
- 休眠核心，休眠实体管理器 5.0.11
我将实体管理器工厂 Bean 定义为
@Bean(name = "entitiesManagerFactory")
@Primary
public EntityManagerFactory entitiesManagerFactory() {
LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
emf.setPersistenceUnitName("DemoEntityPU");
emf.setMappingResources("META-INF/orm.xml");
emf.setDataSource(dataSource());
emf.setPersistenceProvider(hibernatePersistenceProvider());
emf.setJpaVendorAdapter(hibernateJpaVendorAdapter());
emf.setPackagesToScan("com.demo.entities.entity");
Properties properties = new Properties();
properties.setProperty("hibernate.hbm2ddl.auto","validate");
properties.setProperty("hibernate.default_schema", "demoSchema");
properties.setProperty("hibernate.dialect", "org.hibernate.dialect.Oracle10gDialect");
properties.setProperty("hibernate.show_sql", "false");
properties.setProperty("hibernate.generate_statistics", "false");
properties.setProperty("hibernate.format_sql", "true");
properties.setProperty("hibernate.use_sql_comments", "false");
properties.setProperty("hibernate.jdbc.batch_size", "100");
properties.setProperty("hibernate.order_inserts", "true");
properties.setProperty("hibernate.order_updates", "true");
properties.setProperty("hibernate.connection.useUnicode", "true");
properties.setProperty("hibernate.connection.charSet", "UTF-16");
properties.setProperty("hibernate.connection.characterEncoding", "UTF-16");
properties.setProperty("jadira.usertype.autoRegisterUserTypes", "true");
properties.setProperty("jadira.usertype.javaZone", "UTC");
properties.setProperty("jadira.usertype.databaseZone", "UTC");
emf.setJpaProperties(properties);
emf.afterPropertiesSet();
return emf.getObject();
}
例外

我的代码在 tomcat 上运行良好，但是当移动到 weblogic 时，部署时会引发异常。
我不知道为什么涉及eclipselink，即使我在weblogic.xml中定义

<wls:package-name>org.joda.*</wls:package-name>

</wls:prefer-application-packages>
但引发异常并且 weblogic 使用 eclipselink 并忽略我的持久提供程序 bean。
任何帮助或线索将不胜感激。
【问题讨论】：
-
你有persistence.xml吗？它内部是否定义了提供程序？如果没有定义提供程序，WebLogic 将在部署期间使用它附带的默认提供程序加载它 - EclipseLink。这发生在容器管理的持久性单元上，但它不知道什么是容器或本地，直到它加载它们并且应用程序请求一个。
-
@Chris：是的，情况确实如此，我们首先从 persistent.xml 开始，然后移至注释，但没有删除该文件。谢谢你拯救了我的一天。
