在实例化新的EntityManagerFactory时获取DVFactoryException

标签： java hibernate jboss wildfly xerces

我正在为Wildfly 9开发Java Web应用程序。

我写了这个persistence.xml 

<?xml version="1.0" encoding="UTF-8"?>

<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
             http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
             version="2.1">
    <persistence-unit name="Win-Data-PU" transaction-type="JTA">
        <properties>
            <property name = "hibernate.show_sql" value = "true" />
            <property name="jboss.as.jpa.managed" value="true" />
            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
            <property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver" />
            <property name="hibernate.connection.provider_class" value="com.klopotek.core.connection.MyHibernateConnectionProvider" />
            <property name="jboss.entity.manager.factory.jndi.name" value="java:comp/persistence/Api" />
        </properties>
    </persistence-unit>

    <persistence-unit name="Dynamic-PU" transaction-type="RESOURCE_LOCAL">
        <properties>
            <property name="hibernate.show_sql" value = "true" />
            <property name="jboss.as.jpa.managed" value="true" />
            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
            <property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver" />
            <property name="hibernate.connection.provider_class" value="com.klopotek.win.core.connection.DynamicConnectionProvider" />
        </properties>
    </persistence-unit>

</persistence>

如您所见，我为两个持久性单元定义了一个新的Hibernate连接提供程序。

现在我正在尝试为第二个PU实例化一个新的EntityManagerFactory：

EntityManagerFactory emf = Persistence.createEntityManagerFactory("Dynamic-PU");

但是我得到了这个例外

似乎在EMF创建的内部过程中，Java发现this类不会扩展this

但是，如果您在声明中看到，SchemaDVFactoryImpl实现了SchemaDVFactory。

编辑： 我正在使用

  • Java JDK 1.8.0_77但Java JDK 1.8.0_66
    • 也出现了同样的问题
  • WildFly Full 9.0.2.Final
  • Hibernate 4.3.10.Final

您认为您认为发生了什么？

1 个答案:

答案 0 :(得分：0)

JBoss / Wildfly包含自己的 Xerces / Xalan 版本，然后您必须从部署中排除或使用jboss-deployment-structure.xml排除Wildfly模块。
