Question

当我将EclipseLink从2.5.2升级到2.7.4时，在使用Criteria API选择数据时遇到了异常。无论如何，如果我更改为JPQL，则异常消失了。但是，由于使用Criteria API的系统中有很多区域，因此无法将它们全部更改为JPQL。另外，使用EclipseLink 2.5.2时我也没有这样的问题。请帮忙！

    12:09:17,383 ERROR [stderr] (default task-47) Caused by: java.lang.IllegalArgumentException: No [EntityType] was found for the key class [hk.judiciary.icms.model.dao.entity.HrnRsltCd] in the Metamodel - please verify that the [Entity] class was referenced in persistence.xml using a specific <class>hk.judiciary.icms.model.dao.entity.HrnRsltCd</class> property or a global <exclude-unlisted-classes>false</exclude-unlisted-classes> element.

在此附上Critieria API程序：

    CriteriaBuilder builder = getEntityManager().getEntityManagerFactory()
            .getCriteriaBuilder();
    CriteriaQuery<HrnRsltCd> criteria = builder.createQuery(HrnRsltCd.class);
    Root<HrnRsltCd> root = criteria.from(HrnRsltCd.class);
    criteria = criteria.select(root);

    List<Predicate> andPredicates = new ArrayList<Predicate>();

    // Active Flag
    andPredicates.add(builder.equal(root.get(PARAM_ACTIVE_FLAG), "1"));

    if (!CommonUtil.isNullOrEmpty(andPredicates)) {
        criteria.where(andPredicates.toArray(new Predicate[0]));
    }

    TypedQuery<HrnRsltCd> query = getEntityManager().createQuery(criteria);
    return this.getResultList(query);

在这里附加persistence.xml

    <?xml version="1.0" encoding="UTF-8"?>
<persistence
    xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
                        http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0">

                value="org.eclipse.persistence.platform.database.oracle.Oracle11Platform" />
            <property name="eclipselink.target-server" value="JBoss" />
            <property name="eclipselink.composite-unit" value="true" />
            <property name="eclipselink.session.customizer"
                value="hk.judiciary.fmk.ejb.dao.entity.DefaultEntityInterceptor" />
            <property name="eclipselink.deploy-on-startup" value="true"/>
        </properties>  

    </persistence-unit>    

</persistence>

2个jar文件（icms-entity-lib-0.2.9.544.jar和icmshrnmc-ejb.jar）也都有其persistence.xml，它们具有不同的持久性单元名称。

找不到键类的[EntityType]
