Could not resolve Spring property placeholder - spring

Question

I have my config:
<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>
I get the error
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'

I know this could be missing properties file, but I have it in my classpath just right. What is missing?

Answer 1

You may have more than one org.springframework.beans.factory.config.PropertyPlaceholderConfigurer in your application. Try setting a breakpoint on the setLocations method of the superclass and see if it's called more than once at application startup. If there is more than one org.springframework.beans.factory.config.PropertyPlaceholderConfigurer, you might need to look at configuring the ignoreUnresolvablePlaceholders property so that your application will start up cleanly.

Answer 2

Your property file location is classpath:idm.properties
This is rather unusual, it means that idm.properties must be located either at the top level of WEB-INF/classes or at the top-level of one of the jars inside WEB-INF/lib. Usually it's good practice to either use a dedicated folder for properties or keep them close to the context files that use them.
So my suggestion is this: Is your properties file perhaps next to your context file? If so, it's not on the classpath (see this question: Is WEB-INF in the CLASSPATH?).
The classpath: prefix maps to a ClassPathResource, but you probably need a ServletContextResource, and you'll get that from a WebApplicationContext using the syntax without prefix:
<context:property-placeholder location="idm.properties" />
Reference:
The ResourceLoader
(describes how different ApplicationContext types handle resources without prefix)
The PropertyPlaceholderConfigurer
mechanism
(describes the <context:property-placeholder> mechanism)

Answer 3

It's definitely not a problem with propeties file not being found, since in that case another exception is thrown.
Make sure that you actually have a value with key idm.url in your idm.properties.

Answer 4

I still believe its to do with the props file not being located by spring. Do a quick test by passing the params as jvm params. i.e -Didm.url=....

Answer 5

make sure your properties file exist in classpath directory but not in sub folder of your classpath directory. if it is exist in sub folder then write as below classpath:subfolder/idm.properties

Answer 6

the following property must be added in the gradle.build file
processResources {
filesMatching("**/*.properties") {
expand project.properties
}
}
Additionally, if working with Intellij, the project must be re-imported.

Answer 7

Ensure 'idm.url' is set in property file and the property file is loaded
