Hibernate, spring, JPS & isolation -不支持自定义隔离

JPA不支持自定义隔离级别。你可以扩展

HibernateJpaDialect

Connection

这是我写的但尚未测试的东西：

public class HibernateExtendedJpaDialect extends HibernateJpaDialect {    @Override    public Object beginTransaction(EntityManager entityManager, TransactionDefinition definition) throws PersistenceException, SQLException, TransactionException {        Session session = (Session) entityManager.getDelegate();        DataSourceUtils.prepareConnectionForTransaction(session.connection(), definition);        entityManager.getTransaction().begin();        return prepareTransaction(entityManager, definition.isReadonly(), definition.getName());    }}

然后将其定义为你的属性

EntityManagerFactory：

<property name="jpaDialect">    <bean  /></property>
