如何询问hibernate don'；不要读那句话；hibernate.properties“；通过spring配置在类路径中

类路径中有一个由一些工具共享的“hibernate.properties”文件，所以我无法删除它

但是我想为测试创建一个“hibernate.test.properties”，它的内容不同于“hibernate.properties”

然后配置弹簧：

类路径：hibernate.test.properties
${hibernate.hbm2ddl.auto}
${hibernate.dial}
${hibernate.show_sql}

${hibernate.c3p0.idleTestPeriod}s
${hibernate.c3p0.timeout}
${hibernate.c3p0.max_语句}
${hibernate.c3p0.testConnectionOnCheckout}
${hibernate.c3p0.preferredTestQuery}

但是我发现，尽管我在这个文件中指定了新属性，hibernate仍然会从“hibernate.properties”中读取属性并覆盖它们。所以我总是接错电话

有没有办法解决这个问题？

我可以给你几个选择

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>

对于新版本的Spring（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>

... 你的bean定义
... 你的bean定义

然后你可以用Aravind A方法

在“旧方法”中，您可以分离正常和测试spring上下文。这可能是您所做的，但是您的正常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，因为您所做的应该是有效的

使用

org.springframework.beans.factory.config.PropertiesFactoryBean

而不是

org.springframework.beans.factory.config.PropertiesFactoryBean.PropertiesFactoryBean

（spring 3.1.x）
