Hibernate的一个问题

Question

Unknown entity: DepCostsDetails
未知实体
DepCostsDetails.class  这个有没有错

Answer 1

DepCostsDetails.hbm.xml没有做映射mapping,
把它添加到hibernate.cfg.xml文件中,就ok了

Answer 2

是主键的方式有问题,检查一下配置xml吧!
复合主键什么的会影响的,

这个事hibernate.cfg.xml

Answer 6

 public void setId(Serializable id) {
        setCostsDetailsNum(id);
    }你在DepCostsDetails.java文件中加多这个方法试试看

Answer 7

Unknown entity: DepCostsDetails com/provinceoa/hospital/model/DepCostsDetails.hbm.xml我怀疑你的这个文件根本不存在或者里面的类名不是  DepCostsDetails 你注意看看拼写问题吧！

Answer 8

我看你的那个配置中只有　costsDetailsNum　这个列名字，没有id这个列你是否设置了hibernate生成Id主键？？如果没有的话，应该再好好配置一下拉

Answer 9

额，我设置了costsDetailsNum为主键，DepCostsDetails.hbm.xml里面有~！

Answer 10

您说的这两个地方，我看了都不下十回了，没什么问题。我想多问个问题，其他的方法不与映射有关？因为其他的方法，比如说save等等都可以用的。
