Wildfly - 如何在加载持久性之前启动bean?

我想在Wildfly 8.0中加载Persistence Unit之前执行一些逻辑。 我有这样的结构:

  • xxx.ear
    • 之前的持久性-bean.jar
    • beans.jar
    • xxx.war

beans.jar包含具有persistence.XML和会话bean的实体bean

before-persistence-bean.jar包含一个类:

@Startup
@Singleton
public class BeforePersistenceServiceBean {

    @PostConstruct
    public void performOperations() {...}

}

在application.xml中我有:

<initialize-in-order>true</initialize-in-order>
<module>
    <ejb>before-persistence-bean.jar</ejb>
</module>
<module>
    <ejb>beans.jar</ejb>
</module>
<module>
    <web>
        <web-uri>xxx.war</web-uri>
        <context-root>/xxx</context-root>
    </web>
</module>

现在,在启动Wildfly后,我得到错误:

service jboss.persistenceunit."xxx.ear/beans.jar#pu_name" (missing) dependents: 
[service jboss.deployment.subunit."xxx.ear"."before-persistence
bean.jar".component.BeforePersistenceServiceBean.START] 

但是BeforePersistenceServiceBean没有依赖Persistence Unit,这里发生了什么?

--- --- EDIT

在持久性开始之前未能部署此bean之后,我使用了解决方案 类似于CDI Extension for Flyway中描述的(即使用Hibernate Integrator API)

如果您的EAR表明您想要subdeployments isolated,请在jboss-deployment-structure.xml目录中添加META-INF

我认为内容看起来像

<subsystem xmlns="urn:jboss:domain:ee:1.0" >            
  <ear-subdeployments-isolated>false</ear-subdeployments-isolated>
  <sub-deployment name="xxx.war">
    <dependencies>
      <module name="deployment.xxx.ear.beans.jar" />
    </dependencies>
  </sub-deployment>
</subsystem>
