使用 EclipseLinkJpaDialect 在 Spring 中将 PersistenceException 转换为 DataAccessException

Question

你好。 我有同样的问题解释here

主要区别是我使用 EclipseLink 作为JpaProvider。 所以我将我的entityManagerFactory配置如下：

<bean id="entityManagerFactoryCont0" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="persistenceXmlLocation" value="classpath:META-INF/contratto-persistence-cont0.xml" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter"/>
    </property>
    <property name="jpaDialect">
        <bean class="org.springframework.orm.jpa.vendor.EclipseLinkJpaDialect" />
    </property>
</bean> 

我注意到EclipseLink不会覆盖DefaultJpaDialect类的translateExceptionIfPossible方法，这很糟糕......

所以在我的测试用例中我有一个独特的约束冲突异常并且调试控制流显示了这个堆栈跟踪：

EntityManagerFactoryUtils.convertJpaAccessExceptionIfPossible(RuntimeException) line: 282   
EclipseLinkJpaDialect(DefaultJpaDialect).translateExceptionIfPossible(RuntimeException) line: 120   
LocalContainerEntityManagerFactoryBean(AbstractEntityManagerFactoryBean).translateExceptionIfPossible(RuntimeException) line: 368   
ChainedPersistenceExceptionTranslator.translateExceptionIfPossible(RuntimeException) line: 58   
DataAccessUtils.translateIfNecessary(RuntimeException, PersistenceExceptionTranslator) line: 213    
PersistenceExceptionTranslationInterceptor.invoke(MethodInvocation) line: 163   
ReflectiveMethodInvocation.proceed() line: 172

调用的异常是：

javax.persistence.PersistenceException: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.1.2.v20101206-r8635): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: [BEA][Oracle JDBC Driver][Oracle]ORA-00001: unique constraint (JSP_OWN.IDX_MC_CC_RAPPORTI_02) violated

返回的最终异常是一般的 JpaSystemException：

org.springframework.orm.jpa.JpaSystemException: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.1.2.v20101206-r8635): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLIntegrityConstraintViolationException: ORA-00001: violata restrizione di unicità (CONT_OWN.PK_CONT_EVENT_MESSAGE)

知道如何让机器为 EclipseLink 工作吗？ 亲切的问候
