Hibernate xml配置文件

Question

在Tomcat中的war文件中部署webapp时，由于hibernate映射配置错误，我遇到了一个问题。错误的堆栈跟踪如下：

它是由以下代码引起的：

<many-to-one name="editor" class="es.smt.better.bd.model.Usuario" fetch="select">
            <column name="UsuarioId" not-null="true" />
</many-to-one>

它位于这个hibernate映射文件中：

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
    <class name="es.smt.better.bd.model.Edicion" table="EdicionProyecto" schema="dbo" catalog="BtterDevDatabase2">
        <id name="edicionId" type="java.lang.Integer">
            <column name="EdicionId" />
            <generator class="native" />
        </id>
        <property name="fecha" type="timestamp">
            <column name="Fecha" length="23" not-null="true" />
        </property>
        <many-to-one name="editor" class="es.smt.better.bd.model.Usuario" fetch="select">
            <column name="UsuarioId" not-null="true" />
        </many-to-one>

        <many-to-one name="proyecto" class="es.smt.better.bd.model.Proyecto" fetch="select">
            <column name="ProyectoId" not-null="true" />
        </many-to-one>

    </class>
</hibernate-mapping>

我要做的是添加一个名为Edicion的新实体，它包含对"proyecto“类的引用，以及对"usuario”的引用。我在这里不明白的是，对proyecto的引用(数据库中的外键)工作得很好，但通常情况下(外键也是)在进行相同的编码时给出了这个配置错误。如果我评论在部署之前发布的"usuario“代码，但是如果我不对其进行注释，它就会失败。

拜托，我已经花了好几个小时试图解决这个问题，但没有任何结果，如果你能给我任何线索，我会非常感激的。

提前谢谢。

好吧，已经解决了，这是个愚蠢的错误。我在Edicion.java中更改了一个属性名，同时也在相应的getter和setter中更改了它的命名。因为一个愚蠢的错误而损失了几个小时。格里尔

不管怎样，谢谢你！

祝您今天愉快
