引用 1 楼 zhangjihao 的回复:

user_addressmap表也必须对应一个Entity，把这个Entity代码和xml配置贴出来看看

我是按照视频学习的，视频里是没有Entity的

如过要有个Entity，映射文件该如何写

[littlebrain4solving]

仔细检查一下映射文件配置。

哥们，你这个得建两个实体类，一个是User类，属性包括包括主键id，性别gender，名字name，还需要建一个UserAddress类，在配置文件中你配置了User和UserAddress是一个一对多的映射关系，看你的情况应该是这两个实体类都有了，和User实体类关联的表也有了，但是和UserAddress关联的user_addressmap这个表并没有创建。
