jpa，试图从实体创建表，类找不到ExpressionVisitor

Question

因此，当我右键单击项目->JPA工具->从实体创建表时，

我得到以下错误：

线程“main”本地异常堆栈中的异常：异常[EclipseLink-30005]（Eclipse Persistence Services-2.6.0.v20140809-296A69F):org.Eclipse.Persistence.exceptions.Persistence.exceptions.persistenceUnitLoadingException异常描述：在使用classloader:org.Eclipse.Persistence.dynamic.dynamicClassloader@6eceb130内部异常内部异常：java.lang.noClassDefounderror：org/Eclipse/Persistence/jpa/jpql/parser/expressionvisitor at org.Eclipse.Persistence.exceptions.persistenceUnitloadingException.exceptionSearchingforPersistenceResources（persistenceUnitloadingException.java:127)at：55）在org.Eclipse.jpt.jpa.eclipselink.core.ddlgen.main.buildEntityManagerFactory(Main.java:94)在org.Eclipse.jpt.jpa.eclipselink.core.ddlgen.main.execute(Main.java:94)在org.Eclipse.jpa.eclipselink.core.ddlgen.main.execute(Main.java:80)在异常描述：PersistenceUnit[my-pu]预部署失败。内部异常：java.lang.noClassDeffounderror：org/Eclipse/Persistence/jpa/jpql/parser/expressionvisitor at org.Eclipse.Persistence.Internal.jpa.EntityManagerSetupimpl.createPredeployFailedPersistenceException(EntityManagerSetupimpl.java:1973)at org.Eclipse.Persistence.Internal.jpa.EntityManagerSetupimpl.java:1964)at EntityManagerFactoryImpl(PersistenceProvider.java:96)...5个原因是：Exception[EclipseLink-28018](Eclipse Persistence Services-2.6.0.v20140809-296A69F):org.Eclipse.Persistence.exceptions.EntityManagerSetupException异常描述：Predeployment of PersistenceUnit[my-pu]失败。内部异常：java.lang.noClassDeffounderror：org/eclipse/persistence/jpa/jpql/parser/expressionvisitor at org.eclipse.persistence.exceptions.entityManagersetupException.predeployfailed(entityManagersetupException.java:231)...9更多原因是：java.lang.noClassDeffounderror：org/eclipse/persistence/jpa/parser/expressionvisitor at process(namedquerymetadata.process(namedquerymetadata.java:192)在org.eclipse.persistence.Internal.jpa.metadata.metadata.processQueries(MetadataProject.java:1630)在org.eclipse.persistence.Internal.jpa.metadata.metadata.addnamedQueries(MetadataProject.java:148)在快车ionVisitor在java.net.urlClassLoader.findClass(urlClassLoader.java:381)在java.lang.classLoader.loadClass(classLoader.java:424)在sun.misc.launcher$appClassLoader.loadClass(launcher.java:331)在java.lang.classLoader.loadClass(classLoader.java:357)...12个以上

Wildfly默认使用hibernate作为JPA提供程序，我确实将其切换到了Eclipselink。

我将目标库更改为Properties->JPA中的用户定义库。

<persistence-unit name="my-pu" transaction-type="RESOURCE_LOCAL">
    <jta-data-source>java:/forumcsDS</jta-data-source>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>

    <properties>
        <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/forumcs"/>
        <property name="javax.persistence.jdbc.user" value="root"/>
        <property name="javax.persistence.jdbc.password" value="X"/>
        <property name="eclipseLink.ddl-generation" value="drop-and-create-tables"/>
        <property name="eclipseLink.ddl-generation.output-mode" value="database"/>

    </properties>
    </persistence-unit>
