我查询的时候(this_.diary_pet_id=?)这个值为0，这个变量在实体类里是int 类型，为什么它总要加这个条件，怎样把这个条件去掉，请高手帮忙！谢谢了
忘了把语句贴出来了，输出的语句如下：Hibernate: select this_.diary_id as diary1_1_0_, this_.diary_pet_id as diary2_1_0_, this_.diary_date as diary3_1_0_, this_.diary_title as diary4_1_0_, this_.diary_weather as diary5_1_0_, this_.diary_context as diary6_1_0_, this_.diary_is_public as diary7_1_0_, this_.diary_last_modify as diary8_1_0_, this_.diary_author as diary9_1_0_, this_.diary_author_email as diary10_1_0_ from epet.dbo.PetDiary this_ where (this_.diary_pet_id=?)
