Java Hibernate中的联接列错误（一对多）

使用Hibernate时，我遇到了以下问题： 错误不断地告诉我，我有一个错误的实体。有人能不能仔细看看这个问题，因为我不知道出了什么问题

我已将RevalMeasurements.hbm.xml和rewasser.hbm.xml添加到hibernate中。

RevalMeasurement.hbm.xml

java

---

在配置文件中添加了

/hibernate/RevalMeasurement.hbm.xml

，但文件名为

RevalMeasurements.hbm.xml

。请更正配置文件中的文件名。 另外，请在映射文件中提到XSD

<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

发现问题：在我的rewasser.hbm.xml中，我键入了

而不是

您是否在hibernate映射xml文件中映射了revalMeasurements实体？通常我会在上面包含hibernate.xml。很抱歉，这是我的错误，我在创建此问题时输入了一个错误。在我的项目中，配置文件中的名称和文件本身都是正确的。不，不完全是这样，就像我说的：我工作的项目的名称是正确的，我只是在这个线程中键入了错误的文件名。请在两个hbm文件中验证您的关系标记。
