奇怪的行为，只发生em.merge()的第一次调用;后续调用似乎可以正常工作。
这是EJB
@Stateless
@Local
public class PersistenceService implements Serializable
{
private static final long serialVersionUID = 1L;
private static final Logger logger = LoggerFactory.getLogger(PersistenceService.class);
@PersistenceContext
private EntityManager em;
public EntityManager getEntityManager()
{
return em;
}
@PostConstruct
public void init()
{
logger.debug("called");
em.setFlushMode(FlushModeType.COMMIT);
em.setProperty("javax.persistence.cache.retrieveMode", CacheRetrieveMode.USE);
em.setProperty("javax.persistence.cache.storeMode", CacheStoreMode.REFRESH);
UnitOfWork uow = em.unwrap(UnitOfWork.class);
uow.setShouldPerformDeletesFirst(true);
}
public <T extends AbstractEntity> T update(T entity)
{
logger.debug("em.contains(entity): {}", em.contains(entity));
if(entity instanceof NamedEntity)
{
logger.debug("========================> name: {}", ((NamedEntity) entity).getName());
}
// em.clear();
T entity2 = em.merge(entity);
// em.flush();
// em.refresh(entity2);
if(entity instanceof NamedEntity)
{
logger.debug("========================> name: {}", ((NamedEntity) entity2).getName());
}
return entity2;
}
}
这是输出（方括号中有[id@version]）：
Info: update[:192] - em.contains(entity): false
Info: update[:205] - ========================> name: WP 6.6 - SYSTEM SAFETY ASSESSMENT aaaaaaaaaaaaaaaaaaaaaaaaaaaa
Info: update[:216] - ========================> name: WP 6.6 - SYSTEM SAFETY ASSESSMENT
我在使用EclipseLink 2.6.0的GlassFish 4.1
实体由JSF @ViewScoped bean读取：
@ManagedBean
@ViewScoped
public class EntityBean<T extends AbstractEntity> implements Serializable
{
@EJB
protected PersistenceService service;
protected T entity;
@PostConstruct
public void init()
{
Class<T> entityClass = ...;
Long entityId = ...;
entity = service.find(entityClass, entityId);
}
public String update()
{
entity = service.update(entity);
return null;
}
...
}
，这是合并未发生时的输出：
