有一个现有的应用程序，一切正常。但出于各种原因，我不得不从sessionFactory "org.springframework.orm.hibernate3.LocalSessionFactoryBean"切换到entityManagerFactory "org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"。现在我在org.springframework.dao.InvalidDataAccessApiUsageException: Removing a detached instance server.model.instance.ComponentInstance获得了junit-integration.Test。
经过五六个小时毫无结果的谷歌搜索后，我决定在这里写下我的问题。我会很感激，任何帮助都会很棒。
这是junit测试代码，以及堆栈跟踪中提到的代码：
public void deleteComponentInstance ( ComponentInstance instanceToDelete ) {
setComponentInstanceForeignKeyToNull ( instanceToDelete );
deleteAndFlush ( instanceToDelete );
}
方法deleteAndFlush
public <P> void deleteAndFlush ( P persistentObject ) {
Session session = sessionFactory.getCurrentSession ();
session.delete ( persistentObject );
session.flush ();
}
方法setComponentInstanceForeignKeyToNull
public void setComponentInstanceForeignKeyToNull ( Class<?> clazz, String attribute, Object value ) {
StringBuilder hqlQuery = new StringBuilder ()
.append ( "update " )
.append ( clazz.getSimpleName () )
.append ( " entity set entity." ).append ( attribute )
.append ( " = null where entity." ).append ( attribute )
.append ( " = :actualValue" );
Session currentSession = this.sessionFactory.getCurrentSession ();
currentSession.createQuery ( hqlQuery.toString () )
.setEntity ( "actualValue", value )
.executeUpdate ();
}
切换到entityManager后，这是我的“beans.xml”
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="persistenceUnitName" value="spring-jpa" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="false" />
<property name="database" value="HSQL" />
</bean>
</property>
</bean>
<bean id="sessionFactory" factory-bean="entityManagerFactory" factory-method="getSessionFactory" />
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
这是我的beans.xml befor the switch：
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mappingLocations" ref="hibernateMappingFiles" />
<property name="hibernateProperties" ref="hibernateProperties" />
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
我需要的EntityManager persistence.xml：
<persistence-unit name="spring-jpa">
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect" />
<property name="hibernate.show_sql" value="false" />
<property name="hibernate.format_sql" value="false" />
<property name="hibernate.hbm2ddl.auto" value="none" />
<property name="javax.persistence.validation.mode" value="none" />
<property name="hibernate.jdbc.use_streams_for_binary"
value="true" />
<property name="hibernate.jdbc.fetch_size" value="100" />
<property name="hibernate.current_session_context_class" value="org.springframework.orm.hibernate3.SpringSessionContext" />
</properties>

答案 0 :(得分：1)
看起来您错过了JPA的交易配置，它看起来应该与旧的相似：
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="transactionManager"
class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
