Question

在Tomcat中从war文件部署webapp时，我遇到了由错误的hibernate映射配置引起的问题。错误的堆栈跟踪如下：

这是由这段代码引起的：

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

这是在这个hibernate映射文件中的内容：

<?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>

我想要做的是添加一个名为Edicion的新实体，其中包含对“proyecto”类的引用，以及“usuario”的引用。我在这里不明白的是，proyecto的引用（数据库中的外键）运行良好但是usuario（外键也）在进行相同编码时给出了这个配置错误。如果我评论在部署工作之前发布的“usuario”代码片段，但如果我将其取消注释，则会失败。

如果你能告诉我任何可能的信息，我会花费数小时试图解决它，我会非常感激。

提前致谢。

好的，它已经解决了，这是一个愚蠢的错误。我在Edicion.java中更改了一个属性名称，而没有在相应的getter和setter中更改其命名。因愚蠢的错误而浪费了几个小时...... grrrr

非常感谢！

度过愉快的一天
