我试图通过创建从域对象表来测试一对多映射，但我看到错误的mappedBy引用一个未知目标实体属性 。 可能有人来看看好吗？
谢谢

感谢乌拉圭回合答复。 我做了你所提到的变化，也做了一些其他的更改，如添加session.save（flightBenefit）到Main.java和插入=假，可更新=用@JoinColumn注释错误 。 我看到正在创建Employee表而不是FlightBenefit和我所看到的错误
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException：由表造成“TestSchema.flightbenefit”不存在
下面是使用更新的变化和堆栈跟踪类
