无法解析字符串值中的占位符

Question

我试图从.properties文件使用属性，但它不工作。 我得到这个错误：

2017-03-03 11:33:22,893 [localhost-startStop-1] []        ERROR org.springframework.web.context.ContextLoader Context initialization failed 
org.springframework.beans.factory.BeanDefinitionStoreException: 
Invalid bean definition with name 'sessionFactoryInit' 
defined in URL [jar:file:/C:/dev/Escale/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/hx_u4WebServices/WEB-INF/lib/hx_u4Persistence.jar!/META-INF/applicationContext-hibernate-init.xml]: 
Could not resolve placeholder 'ipon.hibernate.show_sql' in string value "${ipon.hibernate.show_sql}" 

你能帮助我吗？

我认为你缺少的属性占位符豆在上下文：

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> 
<property name="location"> 
    <value>file:${IPONN}/config/ipon.properties</value> 
</property>
