java - 使用 Hibernate 配置 Spring。创建名称为 'usersDao' : Unsatisfied dependency expressed through field 'sessionFactory' 的 bean 时出错

Question

我正在尝试使用 Hibernate 5 配置 Spring 4。进行了谷歌研究，但没有帮助。我正在使用 JUnit 测试启动我的应用程序，只是为了看看 Hibernate 是否有效。

Error creating bean with name 'usersDao': Unsatisfied dependency expressed through field 'sessionFactory': Error creating bean with name 'sessionFactory' defined in class path resource [ConfigTest/datasource.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.hibernate.cfg.Configuration.<init>(Lorg/hibernate/boot/MetadataSources;)V; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [ConfigTest/datasource.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.hibernate.cfg.Configuration.<init>(Lorg/hibernate/boot/MetadataSources;)V

这是我的 datasource.xml

            <property name="url" value="${jdbc.url}"></property>
            <property name="password" value="${jdbc.password}"></property>
            <property name="username" value="${jdbc.username}"></property>
        </bean>

        <bean id="sessionFactory"
            class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
            <property name="dataSource" ref="dataSource"></property>
            <property name="hibernateProperties">
                <props>
                    <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>

                </props>
            </property>
            <property name="packagesToScan">
                <list>
                    <value>DAO</value>
                </list>
            </property>
        </bean>

    </beans>

</beans>

另外，当我使用 Hibernate 4 时，我遇到一个错误:

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'offersDao': Injection of autowired dependencies failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/cache/spi/RegionFactory

但我在该地址确实有 RegionFactory: enter image description here

提前致谢!

Answer 1

它appears that the packagesToScan property wants an array .

就你的情况而言，我想它看起来像这样......

<property name="packagesToScan">
    <array>
        <value>DAO</value>
    </array>
</property>

或者也许只是......

<property name="packagesToScan" value="DAO" />
