Hibernate - 查询对实体中的所有字段返回 null，而同一查询从数据库完美返回

Question

Hibernate - 查询对实体中的所有字段返回null

Long fooId = 39;    
Query query = getCurrentSession().createQuery("from FooEntity where deleted IS FALSE AND id=:fooId" );
query.setParameter( "fooId", fooId );
FooEntity fooEntity = ( FooEntity ) query.uniqueResult();

检查 FooEntity，显示以下结果

(id=null, name=null, deleted=null)

虽然相同的查询从数据库返回完美的结果

select * from foo where deleted IS FALSE AND id=39
(id, name, deleted) => (39, 'Bar', false)

It has to be noted that this occurs in random cases only. Most of the time hibernate returns perfect result.

请尝试log或sysout下一行中的值。

对于我和OP来说，问题是相同的，只是Java调试器没有显示该值。价值一直存在。
