Question

我的项目使用的是hibernate3和spring 2.5。现在，我使用JPA将其迁移到Spring5和hibernate5。我有hbm.xml用于使用休眠映射的实体。迁移后，我得到了错误：

由以下原因引起：org.hibernate.AssertionFailure：无法找到引用的对象实体映射[com.mycompany.common.admin.Entity1]以便处理多对一FK：com.mycompany.common.admin.Entity2

Entity2具有参考Entity1的多对一FK

applicationContext.xml中用于实体管理工厂的代码：

    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
            <property name="dataSource">
                <ref bean="myDataSource"/>
            </property>
            <property name="packagesToScan" value="com.mycompany"/>
            <property name="jpaVendorAdapter" ref="hibernateJpaVendorAdapter"/>
            <property name="persistenceUnitPostProcessors">
            <list>
                <bean
    class="org.springframework.data.jpa.support.ClasspathScanningPersistenceUnitPostProcessor">
                    <constructor-arg index="0" value="com.mycompany" />
                    <property name="mappingFileNamePattern" value="classpath*:com/**/*hbm.xml" />
                </bean>
            </list>
        </property>
            <property name="jpaProperties">
                <props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL8Dialect</prop>
                    <prop key="hibernate.show_sql">false</prop>
                </props>
            </property>
        </bean>

Entity2的hbm.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class name="com.mycompany.common.admin.Entity2" table="entity2">
        <id column="id" name="ID">
            <generator class="uuid"/>
        </id>
        <property name="name" type="string">
            <column name="name"/>
        </property>
        <many-to-one class="com.mycompany.common.admin.Entity1" name="entity1" not-null="true"/>

    </class>
</hibernate-mapping>

错误堆栈跟踪：

请让我知道我在这里想念什么。
