Could not resolve placeholder | Spring Placeholder
spring
Solution
It sounds as though you're using a Maven project structure. Placing your `project.properties` inside `src/main/resources` is normal practice for resource files - as Maven will automatically transfer these to the classpath of the final artifact - which will be `/WEB-INF/classes` inside your war.
However, you should modify the `location` attribute of your `<context:property-placeholder>` tag and remove the `resources` folder prefix. The `resources` folder itself is not transferred to `/WEB-INF/classes` when the war file is built - and so won't be part of the runtime classpath. Just the folder contents are transferred.
<context:property-placeholder location="classpath:project.properties" />
Problem
I am trying to use Spring `<context:property-placeholder>` in my application for first time and encountering some issues, I have tried many things as well already Google and have seems few posts over SO. I am having a web application and need to pass some keys to underlying Class, was thinking of using place holder for same.Here is the structure of my application ``` Main -java -resources -webapp ``` I have a `project.properties` file which is inside `resource` folder, this is how I am trying ``` <context:property-placeholder location="classpath:resources/project.properties" /> <beans:bean id="reCaptcha" class="net.tanesha.recaptcha.ReCaptchaImpl"> <beans:property name="privateKey" value="${demo.recapatcha_private_key}"/> <beans:property name="publicKey" value="${demo.recapatcha_public_key}"/> </beans:bean> ``` But I am getting following exception on server startup ``` org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'reCaptcha' defined in ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml]: Could not resolve placeholder 'demo.recapatcha_private_key' ``` I have already tried placing project.properties file at various location which includes inside `WEB-INF/classes` and few other location at `webapp` but with no success.not sure what I am doing wrong
