java - HibernatePersistenceProvider.createEntityManagerFactory() 方法的 JBoss AS7 LinkageError

Question

我正在创建一个 Spring MVC 和 Hibernate/JPA Web 应用程序，但在配置应用程序和 jboss 部署描述符时遇到问题，以便我可以将持久性管理委托(delegate)给我的 Web 应用程序而不是 JBoss AS7。 我正在针对 JavaEE7、Spring 4.2.2-Final 和 Hibernate 4.3.11 进行开发。

这是我的jboss-deployment-struct.xml的内容

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure >
<deployment>
    <exclude-subsystems>
        <subsystem name="jpa"/>
    </exclude-subsystems>
    <exclusions>
        <module name="org.hibernate" />
        <module name="javaee.api" />
        <module name="javax.persistence.api" />
    </exclusions>
    <dependencies>
        <module name="javaee.api">
            <imports>
                <exclude path="javax/persistence" />
            </imports>
        </module>
    </dependencies>
</deployment>
</jboss-deployment-structure>

使用这个，我能够依靠其默认的 hibernate-jpa-2.0-api.jar 解决 AS7 的初始问题，并使用与我的 Web 应用程序一起部署的 hibernate-jpa-2.1-api.jar 。

但是，我现在通过管理控制台启动网络应用程序时遇到此错误。

从异常情况来看，显然 javax.persistence.EntityManagerFactory 类的 Jboss ModuleClassLoader 存在冲突。我认为我的部署描述符中的条目会阻止这种情况，但显然情况并非如此。

我是一位经验丰富的软件工程师，在应用程序服务器管理方面有一些经验，但老实说，仅够危险。通常，我会依赖服务器管理团队，但这里没有这样的团队。

有人有过这种情况或类似情况的经验吗？ 关于如何修复此 LinkageError 并解决冲突有什么想法吗？

提前谢谢您，

Answer 1

我在使用 JBoss EAP 6.4、Spring 4.2.4 和 Hibernate 4.3.11 时也遇到了类似的问题。

我使用以下 jboss-deployment-struct.xml 并能够部署我的 Web 应用程序:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <exclude-subsystems>
            <subsystem name="jpa" />
        </exclude-subsystems>
        <exclusions>
            <module name="javaee.api" />
            <module name="javax.persistence.api" />
        </exclusions>
        <dependencies>
            <module name="javaee.api">
                <imports>
                    <exclude path="javax/persistence" />
                </imports>
            </module>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

但是，每次我重新部署 Web 应用程序时，我都会遇到与您类似的 LinkageError 问题。 实现此处描述的解决方法 2 后，一切正常:https://issues.jboss.org/browse/WFCORE-209 .
