无法解析Spring属性占位符
我有我的配置：
<context:property-placeholder location="classpath:idm.properties" /><bean id="idmPropertyHolder" class="fi.utu.resurssitilaus.idm.IdmPropertyHolder">
<property name="url" value="${idm.url}" />
<property name="user" value="${idm.user}" />
<property name="password" value="${idm.password}" />
<property name="proxyHost" value="${http.proxyHost}" />
<property name="proxyPort" value="${http.proxyPort}" />
</bean>
我得到错误
SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'idmPropertyHolder' defined in ServletContext resource [/WEB-INF/idm-config.xml]: Could not resolve placeholder 'idm.url'

我知道这可能缺少属性文件，但是我在类路径中恰好有它。有什么不见了？

回答：
你org.springframework.beans.factory.config.PropertyPlaceholderConfigurer的应用程序中可能有多个。尝试setLocations在超类的方法上设置一个断点，看看在应用程序启动时是否多次调用了该断点。如果不止一个org.springframework.beans.factory.config.PropertyPlaceholderConfigurer，则可能需要查看配置ignoreUnresolvablePlaceholders属性，以便你的应用程序可以正常启动。
