Mysql 非主键联接列上的OneTONE映射
这是我的person实体，我希望person选项卡映射到person\u contact\u number表，并使用person\u contact\u number表的person\u id（外键）映射到person表的id列Mysql 非主键联接列上的OneTONE映射,mysql,hibernate,Mysql,Hibernate,这是我的person实体，我希望person选项卡映射到person\u contact\u number表，并使用person\u contact\u number表的person\u id（外键）映射到person表的id列 这是我的测试课 既然您已经映射了这两个实体及其关系，我猜您在启动时会出错？如果是的话，介意把它添加到问题中吗？嗨，我已经更新了我的测试类。我已经在代码中添加了堆栈跟踪。提前谢谢我猜这是从额外的personId字段中得到的。如果不需要直接读取id，只需将其删除即可（映射
