无法parsingSpring属性占位符
我有我的configuration：
<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

我知道这可能是缺less属性文件，但我在我的类path正好。 什么不见了？
我的web.xml：

您的应用程序中可能有多个org.springframework.beans.factory.config.PropertyPlaceholderConfigurer 。 尝试在超类的setLocations方法上设置一个断点，看它在应用程序启动时是否被调用多次。 如果有多个org.springframework.beans.factory.config.PropertyPlaceholderConfigurer ，则可能需要查看configurationignoreUnresolvablePlaceholders属性，以便您的应用程序可以干净地启动。
您的属性文件位置是classpath:idm.properties
这很不寻常，这意味着idm.properties必须位于WEB-INF/classes的顶层，或者位于WEB-INF/lib内的其中一个jar的顶层。 通常最好的做法是使用专用的文件夹来保存属性，或者使它们靠近使用它们的上下文文件。
所以我的build议是这样的：你的属性文件可能是旁边的上下文文件？ 如果是这样，它不在类path中（请参阅此问题： 在CLASSPATH中是否为WEB-INF？ ）。
classpath:前缀映射到一个ClassPathResource ，但是你可能需要一个ServletContextResource ，并且你将从一个WebApplicationContext使用没有前缀的语法来获得它：
<context:property-placeholder location="idm.properties" />
参考：
-
ResourceLoader
（描述不同的ApplicationContexttypes如何处理没有前缀的资源） -
PropertyPlaceholderConfigurer机制
（描述<context:property-placeholder>机制）
propeties文件没有被发现肯定不是问题，因为在这种情况下会抛出另一个exception。
确保你的idm.url中的关键字idm.url具有真正的值。
我仍然相信这是与spring所定位的道具文件。 通过传递参数作为jvm参数进行快速testing。 即-Didm.url = ….
确保您的属性文件存在于classpath目录中，但不在您的classpath目录的子文件夹中。 如果它存在于子文件夹中，则按如下所示写入classpath：subfolder / idm.properties
确保在属性文件中设置“idm.url”，并加载属性文件
