Loading a Properties object in the application context

[Wm Stafford]

I need to inject a Properties object into several classes. Because a Properties object must be "loaded" I don't see a way to do this via the usual Spring applicationContext instantiation and assignment.

I was thinking of overloading Properties and providing a constructor that called load but as I thought about this I felt like this situation must have been dealt with before.

Is there a Spring provided way to do this?

Thanks,

Doesn't PropertiesFactoryBean do everything you want?

Karldmore,

I looked at the PropertiesFactorBean class before posting and I could not see how it could do what I want. Can you point me to an example?

What confuses me about PropertiesFactoryBean is that there is no load() method that takes the name of a properties file on the classpath. Does this class load the properties some other way?

Thanks for the reply,

Karldmore,
Nevermind! I searched for an example with Google and found a good one. I think my basic problem with Spring is that Spring makes everything so simple and I'm always trying to make things more difficult.

Thanks again for the reply,

You just need to inject the location, depending on what you set for this it could be a classpath location.

If you are using Spring 2.x, you can even use the 'util' namespace as a shortcut for the factory bean, such as:

<util:properties id="emails" location="/WEB-INF/emails.properties"/>

<bean id="mailService" class="xyz.MailSenderImpl">
   <property name="emailMap" ref="emails"/>
</bean>
