JBoss AS 7 不使用 WEB-INF 休眠库并抛出 "Unknown service requested [org.hibernate.boot.registry.classloading.spi.ClassLoaderService]"

Question

我正在将 Spring+Hibernate 应用程序从 Weblogic 12c 迁移到 JBoss AS 7，但出现以下错误：

20:07:47,395 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC00001: Failed to start service jboss.persistenceunit."connecta-presenter-2.2.1.war#ConnectaPresenterPU": org.jboss.msc.service.StartException in service jboss.persistenceunit."connecta-presenter-2.2.1.war#ConnectaPresenterPU": Failed to start service

org.hibernate.service.internal.AbstractServiceRegistryImpl的第126行抛出的Unknown service requested [org.hibernate.boot.registry.classloading.spi.ClassLoaderService]消息是一个异常只在Hibernate Core的4.0.1版本中抛出，这是版本在我的 JBoss AS 7 模块文件夹中。

问题是我的应用程序使用 Hibernate 4.3.10，并且这个特定的行在这个版本中不存在（我可以看到比较源代码 Github).

JBoss AS 7 站点上的以下文档指出，当您从 Weblogic 迁移到 JBoss 时：

https://docs.jboss.org/author/display/AS72/How+do+I+migrate+my+application+from+WebLogic+to+AS+7#HowdoImigratemyapplicationfromWebLogictoAS7-Migrateweblogic.xmlDescriptorFileConfigurations

所以jboss-web.xml文件中没有如下代码:

<prefer-application-packages>
  <package-name>javassist.*</package-name>
</prefer-application-packages>

它说 JBoss 总是在内部模块之前使用 WEB-INF/classes 和 WEB-INF/lib。

知道发生了什么吗？

如果您想使用自己的特定版本的 Hibernate（或任何其他 service/software 版本），您可以这样做而不是依赖 JBoss AS 7 模块。

创建一个新的文件夹结构，例如在您的 $JBOSS_HOME\modules\system\layers\base\ 目录中 org/myhibernate/main。将所需的 jar（比如 my.jar）放入主文件夹并创建一个 module.xml 文件，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
 <module xmlns="urn:jboss:module:1.1" name="org.myhibernate">
 <resources>
<!-- Modules -->
<resource-root path="my.jar" />
</resources>
<dependencies>
        <module name="javax.api"/>
        <module name="sun.jdk"/>          
</dependencies>
</module>

现在在您工作区的 EAR/web 文件夹中创建一个 jboss-deployment-structure.xml 并包含此依赖项 -

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <sub-deployment name="yourfile.war">
        <dependencies>          
            <module name="org.myhibernate" />                       
        </dependencies>
    </sub-deployment>
</jboss-deployment-structure>

JBoss AS 7 不使用 WEB-INF 休眠库并抛出 "Unknown service requested [org.hibernate.boot.registry.classloading.spi.ClassLoaderService]"

JBoss AS 7 not using WEB-INF hibernate lib and throwing "Unknown service requested [org.hibernate.boot.registry.classloading.spi.ClassLoaderService]"
