创建beanorg.springframework.orm.hibernate时出错4. HibernateTransactionManager

许彦
2023-03-14

当我尝试为org.springframework.orm.hibernate4. HibernateTransactionManager创建bean时，我得到org.springframework.beans.factory.BeanCreationException

我用的是：

  • Hibernate4.0.1。最终
  • Spring 3.2.2。释放
  • Spring Tool Suite，版本：3.6.4。发布，构建ID：201503100339，平台：Eclipse Luna SR1（4.4.2）
  • JDK 1.7
  • Tomcat v8.0服务器

这是道家。配置Hibernate daos和sessionFactory的xml文件：

这是我的pom。maven依赖的xml配置。

我的xml配置文件有什么问题？

首先，我会检查您的类路径，看看您是否没有与spring相关的JAR的混合依赖项。

然后我将删除java。util。ArrayListbean并使用

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">false</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>
            <prop key="hibernate.query.substitutions">true='T',false='F'</prop>
        </props>
    </property>
    <property name="mappingLocations">
        <list>
            <value>classpath:/com/myapp/persistence/mappings/User.hbm.xml</value>
        </list>
    </property>
</bean>

我还删除了hibernate.connection.*属性，因为这些属性由于注入了DataSource而不做任何事情。此外，hibernate.current_session_context_class也被删除，因为它已经由Spring设置。乱搞通常会破坏正确的事务管理。

  1. LocalSessionFactoryBean没有构造函数参数（请参阅JavaDoc）
  2. 您可以使用公共无效setMappingLocations（资源... mappingLocations）（参见JavaDocs to）
  3. 你可以效仿Mkong的例子，解释得很好

这也是我配置会话工厂的方式：

<bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

        <property name="dataSource">
            <ref bean="dataSource" />
        </property>

        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>
                <prop key="hibernate.show_sql">false</prop>
            </props>
        </property>

        <property name="mappingLocations">
            <list>
                <value>classpath:com/fenix/infrastructure/persistence/db/mapping/Usuario.hbm.xml
                </value>
                <value>classpath:com/fenix/infrastructure/persistence/db/mapping/ConfirmacionCorreo.hbm.xml
                </value>
                ...
            </list>
        </property>

    </bean>

我刚把我的sts改成：

  • Spring工具套件
  • 版本：3.6.4。发布
  • 构建ID：201503100339
  • 平台：Eclipse Luna SR1（4.4.2）

它奏效了。

我还换了DAO。xml配置如下所示，只是为了通过向sessionFactory添加mappingDirectoryLocations属性来避免写入每个hbm配置文件路由（myapp仅通过更改我的sts版本工作，此daos.xml配置只是为了优化旧配置）：
