在这种情况下有人帮助我吗？我正在使用hibernate从db中选择数据，但是当我从sql调试日志中检查时。我总是看到在使用“select”sql从DB获取数据后打印的更新sql。

编辑：获取数据的代码：
@Override public MObjectId findResult(final MObjectId id, boolean isLocked)
{
Criteria c = getSession().createCriteria(Test.class);
c.add(Expression.eq("objectId", id));
if(isLocked)
{
c.setLockMode("this", LockMode.UPGRADE);
}
Test extension = (Test) c.uniqueResult();
return (extension != null)
? new MObjectId("/ontPotsSipExtNr=" + extension.getId())

最有可能的情况是，实体的某个属性不会返回加载后由hibernate设置的完全相同的值。你是否在getter或setter中有一些if语句，如null处理或类似的东西？
答案 1 :(得分：0)
升级锁定。在此锁定模式下加载的对象使用SQL select ...进行更新。
与sql
中的select for update相同如果您不想选择更新，请删除以下代码并重新运行
if(isLocked)
{
c.setLockMode("this", LockMode.UPGRADE);
}
答案 2 :(得分：0)
我遇到了同样的问题，其中激活select之后的select语句最终会出现在update语句中。这是在我从websphere 7.0迁移到Jboss 7.0之后发生的。
Object具有String属性，其中select返回“Y”或“N”，因此hibernate触发了更新的思维，对象的值发生了变化。
我所做的就是在我的hbm.xml中我将该属性标记为update =“false”。
<property name="someStringProperty" type="string" update="false"/>
