java - 未找到 Hibernate-Component 类

Question

我不明白这是怎么回事。这是我遇到的异常:

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in URL [file:/C:/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/demoBancoWeb/WEB-INF/classes/applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Unable to instantiate default tuplizer [org.hibernate.tuple.component.PojoComponentTuplizer]

堆栈跟踪的第一个 block 是 Hibernate 异常，第二个跟踪 block 是与我的类的关系。

该类 ConsignacionesId 是由 Hibernate 自动生成的多属性 ID。

这是我的 hibernate cfg.xml :

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
                                         "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
 <session-factory>
  <property name="hibernate.bytecode.use_reflection_optimizer">false</property>
  <property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
  <property name="hibernate.connection.password">admin</property>
  <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/banco</property>
  <property name="hibernate.connection.username">postgres</property>

  <mapping resource="co/edu/icesi/demo/modelo/Cuentas.hbm.xml"/>
  <mapping resource="co/edu/icesi/demo/modelo/TiposUsuarios.hbm.xml"/>
  <mapping resource="co/edu/icesi/demo/modelo/TiposDocumentos.hbm.xml"/>
  <mapping resource="co/edu/icesi/demo/modelo/Consignaciones.hbm.xml"/>
  <mapping resource="co/edu/icesi/demo/modelo/Usuarios.hbm.xml"/>
  <mapping resource="co/edu/icesi/demo/modelo/Retiros.hbm.xml"/>

    <mapping resource="co/edu/icesi/demo/modelo/Consultas.hbm.xml"/>

 </session-factory>
</hibernate-configuration>

最后，这是我由 Hibernate 生成的类:

如您所见，ConsignacionesId 就在那里。如有任何帮助，我们将不胜感激。

好吧，我缺少 hibernate hbm.xml 文件中类的完整路径。

这个:

    <?xml version="1.0"?>
    <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
    <!-- Generated 01-feb-2016 18:51:34 by Hibernate Tools 4.0.0 -->
    <hibernate-mapping>
        <class name="Clientes" table="clientes" schema="public">
            <id name="cliId" type="long">
                <column name="cli_id" precision="10" scale="0" />
                <generator class="assigned" />
            </id>
            <many-to-one name="tiposDocumentos" class=
.
.
.

必须看起来像这样:

    <?xml version="1.0"?>
    <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
    <!-- Generated 01-feb-2016 18:51:34 by Hibernate Tools 4.0.0 -->
    <hibernate-mapping>
        <class name="co.edu.icesi.demo.modelo.Clientes" table="clientes" schema="public">
            <id name="cliId" type="long">
                <column name="cli_id" precision="10" scale="0" />
                <generator class="assigned" />
            </id>
            <many-to-one name="tiposDocumentos" class="

所以我刚刚粘贴了“co.edu.icesi.demo.modelo”。在我生成所有类之前，它起作用了。

我希望这对某人有帮助。

发生这种情况是因为在“Hibernate Code Generation Cofigurations...”中我没有使用“package”字段。

“destiny”文件夹应该只有 src/main/java。

不要自己创建保存生成的类的包。就我而言，不要创建 co.edu.icesi.demo.modelo。

该路径位于“Hibernate Code Generation Configurations...”的“package”字段内
