带有Hibernate 5.4的WebLogic 12c(12.2.1.4) [英] WebLogic 12c (12.2.1.4) with Hibernate 5.4

问题描述

我有一个使用Hibernate 5.2.18部署在WebLogic 12c(12.2.1.4)上的应用程序. Weblogic 12c文档参考了JPA 2.1兼容性，而Hibernate 5.3+需要JPA 2.2.我可以在启动类路径之前添加JPA 2.2 API并使用Hibernate 5.3+吗?还是暂时应该坚持使用Hibernate 5.2?

I have an application deployed on WebLogic 12c (12.2.1.4) using Hibernate 5.2.18. Weblogic 12c doc references JPA 2.1 compatibility and Hibernate 5.3+ requires JPA 2.2. Can I prepend the JPA 2.2 API to my startup classpath and use Hibernate 5.3+ or should I stick with Hibernate 5.2 for the time being?

推荐答案

是的，此配置是可能的.

Yes, this configuration is possible.

为避免与WebLogic内置JPA功能发生冲突，您应该执行以下操作:

To avoid conflicts with WebLogic built-in JPA capabilities you should do the following:

1. 根据此

在完整的Java EE环境中，请考虑从JNDI获得您的EntityManagerFactory.或者，在LocalContainerEntityManagerFactoryBean定义上指定一个自定义persistenceXmlLocation(例如，META-INF/my-persistence.xml)，并在应用程序jar文件中仅包含具有该名称的描述符.由于Java EE服务器仅查找默认的META-INF/persistence.xml文件，因此它会忽略此类自定义持久性单元，因此避免了与Spring预先驱动的JPA设置产生冲突.

In a full Java EE environment, consider obtaining your EntityManagerFactory from JNDI. Alternatively, specify a custom persistenceXmlLocation on your LocalContainerEntityManagerFactoryBean definition (for example, META-INF/my-persistence.xml) and include only a descriptor with that name in your application jar files. Because the Java EE server looks only for default META-INF/persistence.xml files, it ignores such custom persistence units and, hence, avoids conflicts with a Spring-driven JPA setup upfront.

您可以在spring上下文配置中使用类似的内容.

You can use something like this in the spring context config.

<?xml version="1.0" encoding="UTF-8"?>
<beans>
    <!-- ... -->
    <jee:jndi-lookup id="DS" jndi-name="appDS" />
    <bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
       <property name="persistenceXmlLocation" value="classpath:META-INF/app-persistence.xml" />
       <property name="dataSource" ref="DS" />
    </bean>
    <!-- ... -->
</beans>

1. 根据此

要配置FilteringClassLoader以指定从应用程序中加载某个软件包，请在weblogic-application.xml中添加一个prefer-application-packages描述符元素，该元素详细说明要从该应用程序中加载的软件包列表.

To configure the FilteringClassLoader to specify that a certain package is loaded from an application, add a prefer-application-packages descriptor element to weblogic-application.xml which details the list of packages to be loaded from the application.

您应将以下代码段添加到META-INF/weblogic-application.xml

You should add the following snippet to your META-INF/weblogic-application.xml

<?xml version="1.0" encoding="UTF-8"?>
<weblogic-application>
    <prefer-application-packages>
        <!-- ... -->
        <package-name>javax.persistence.*</package-name>
    </prefer-application-packages>
</weblogic-application>
