How do I get a property value from an ApplicationContext object? (not using an annotation)
Assuming that the ${someProp}
property comes from a PropertyPlaceHolderConfigurer, that makes things difficult. The PropertyPlaceholderConfigurer is a BeanFactoryPostProcessor and as such only available at container startup time. So the properties are not available to a bean at runtime.
A solution would be to create some sort of a value holder bean that you initialize with the property / properties you need.
@Componentpublic class PropertyHolder{ @Value("${props.foo}") private String foo; @Value("${props.bar}") private String bar; // + getter methods}
Now inject this PropertyHolder wherever you need the properties and access the properties through the getter methods
