Hibernate 5 持久化并刷新以该实例结尾的实体在数据库中还不存在作为一行
Hibernate 5 persist and refresh an entity ends with this instance does not yet exist as a row in the database
我刚刚将 Hibnernate 从版本 3.3.1.GA 迁移到版本 5.3.3.Final。 Everythink 工作正常，除了一个 think。如果我保留一个实体，将其刷新并提交到数据库，那么该实体确实存在于数据库中（我用 select 语句检查了它）。但是如果我刷新这个实体。我收到以下异常：

我调试了一下这里是Trace：
MutableEntityEntry(AbstractEntityEntry).getCompressedValue(AbstractEntityEntry$BooleanState) line: 516
MutableEntityEntry(AbstractEntityEntry).isExistsInDatabase() line: 228
DefaultRefreshEventListener.onRefresh(RefreshEvent, Map) line: 117
DefaultRefreshEventListener.onRefresh(RefreshEvent) line: 48
SessionImpl.fireRefresh(RefreshEvent) line: 1306
SessionImpl.refresh(Object) line: 1257
在第 516 行 MutableEntityEntry 中有一个 return 语句
return ( ( compressedState & state.getMask() ) >> state.getOffset() ) == 1;
变量是：
compressedState=17 == 0001 0001
(looking in the code)
(0001 the 4. positions means 4 - existsInDatabase ???)
(What does 17 mean ???)
state.getMask()=8192
state.getOffset()=13
所以==>
( ( 17 & 8192 ) >> 13 ) == 1
==> False
==> MutableEntityEntry(AbstractEntityEntry).isExistsInDatabase() line: 228 is false ???WHY???
==> in line 228 MutableEntityEntry
throw new UnresolvableObjectException(
e.getId(),
"this instance does not yet exist as a row in the database"
);
为什么压缩状态是17？它应该是什么，我该如何更改它？
PS：我正在使用 Java 10 和旧的 Framework Seam 2.2。2.Final 我现在无法升级它。
PPS：Seam 2.2.2 是针对 Hibernate 3 编译的，为了迁移到 Hibernate 5 我不得不扩展两个接口和一个 class，因为它们移动到不同的包中：
SessionImplementor
package org.hibernate.engine;
public interface SessionImplementor extends org.hibernate.engine.spi.SessionImplementor {}
事件源
package org.hibernate.event;
public interface EventSource extends org.hibernate.event.spi.EventSource {}

public class CustomHibernatePersistenceProvider extends HibernatePersistenceProvider {

return classMetadata != null && classMetadata.isVersioned() ? classMetadata.getVersion(value) : null;
}
private static ClassMetadata getClassMetadata(final Object value, final Session session) {
Class entityClass = getEntityClass(value);
ClassMetadata classMetadata = null;
if (entityClass != null) {
classMetadata = session.getSessionFactory().getClassMetadata(entityClass);
if (classMetadata == null) {
throw new IllegalArgumentException(
"Could not find ClassMetadata object for entity class: " + entityClass.getName());
}
}
return classMetadata;
}
@Override
public Object getVersion(final Object bean, final EntityManager entityManager) {
try {
return getVersion(bean, getSession(entityManager));
} catch (NotHibernateException nhe) {
return super.getVersion(bean, entityManager);
}
}
private Session getSession(final EntityManager entityManager) {
Object delegate = entityManager.getDelegate();
if (delegate instanceof Session) {
return (Session) delegate;
} else {
throw new NotHibernateException();
}
}
}
编辑：该错误已在 Hibernate 版本 5.3.8 中修复。和 5.4.1.!!!
