Question

classpath中有一个“hibernate.properties”文件，由某些工具共享，所以我无法将其删除。

但是我想创建一个用于测试的“hibernate.test.properties”，其内容与“hibernate.properties”不同。

然后我配置弹簧：

        </property>
    </bean>

    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="hibernateProperties" ref="hibernateProps" />

    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">

    </bean>

    <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
        <constructor-arg ref="sessionFactory" />
    </bean>

</beans>

但我发现虽然我在这个文件中指定了新属性，但hibernate仍会从“hibernate.properties”中读取属性并覆盖它们。所以我总是得错了。

有没有办法解决它？

Answer 1

我可以提供几种选择。

在hibernate.test.properties中，尝试更改属性名称。

将单独的属性文件注入hibernateproperties

<property name="hibernateProperties">
       <bean class="org.springframework.beans.factory.config.PropertiesFactoryBean.PropertiesFactoryBean">
       <property name="location" value="classpath:myHibernate.properties"/>
   </bean>
</property>

Answer 2

使用Spring的新版本（3或3.1？），您可以使用Spring配置文件：

<beans profile="test">
   ... your bean definitions
</beans>
<beans profile="normal">
   ... your bean definitions
</beans>

然后你可以使用Aravind A方法

在“旧方式”中，您可以分离正常和测试弹簧上下文。这可能就是你所做的，但是你的常规hibernate.properties是如何加载并用作占位符的呢？您的上下文层次结构中可能存在一些问题，因为您所做的事情应该起作用

如何让hibernate不通过spring配置读取类路径中的“hibernate.properties”
