org.springframework.validation.BindException: org.springframework.validation.Bea

[wenfanhugh]

第一次遇到这样的问题，请大家帮下忙
大体上就是user这个实体类中有Role和Org这两个实体类。
请大家帮帮忙，这到底是什么问题，在网上也查过相关资料，说是什么数据绑定或者是什么类型转换出错。但是我先前是没有出错的，只是后来清空数据库之后再次运行就抱着个错了.

org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 2 errors Field error in object 'user' on field 'role': rejected value [[object Object]]; 应该是 user和role这2个对象映射时错误 光看这个定位不了错误 把你的xml 和配置文件贴出来

[BUG胡汉三]

确实是转换的问题！！！ 转换的时候数据为空会报错的！ 添加数据就好！

org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 2 errors Field error in object 'user' on field 'role': rejected value [[object Obj……

谢谢你的回复，我不是用xml,是在注解上实现的 在User这个实体类中的role和org属性如下： @ManyToOne Role role; @ManyToOne Org Org;

可是关联的这两个对象并不是必须填的吖~ 对数据库来说就是关联另外两张表的ID

可以为空的怎么解决啊 我不想填呢
