推荐答案
可能，您的实体的属性之一不会返回与加载后由hibernate设置的完全相同的值。你有一些if语句，如null处理或类似这样的getter或setter？
Most probably, one of the properties of your entity does not return the exact same value that is set by hibernate after loading. Do you have some if statements like null handling or anything like this in a getter or setter?
