How to load configuration parameters from XML files into Spring MVC Controllers?

Question

I've noticed that I can load a config parameter into a bean using something like this in application-context.xml:

<beans:bean id="foo" class="com.foo.FooBean">
    <beans:property name="foo" value="${foo}" />
</beans:bean>

What about if I want to access the foo value in a Controller without instantiating a bean? Is there a way to do that?

Do you want to get the value in your controller without instantiating FooBean? — Pushkar

Why not use Danny's suggestion and inject ${foo} into your controller from a properties file? — Fil

You can use the @Value annotation with util:properties

<util:properties id="props" location="classpath:com/foo/bar/props.properties"/>

And in your controller class, assuming you have a property with key 'foo':

@Value("#{props.foo}")
public void setFoo(String foo) {
    this.foo = foo;
}
