Is there a way to load multiple application properties files in Apache Wicket?

Question

My WicketApplication.properties file has grown very large, and now to keep it more readable I want to categorize properties in different files. Is there a way to accomplish that and still access the properties like if they were all in the WicketApplication.properties?

Answer 1

See org.apache.wicket.settings.IResourceSettings.addStringResourceLoader(IStringResourceLoader). You can implement your own IStringResourceLoader which may load from wherever your want.

Answer 2

You can use property files dedicated per page or even component:

• AddressPicker.properties - properties specific to an AddressPicker.java componen
• ProfilePage.properties - properties used only on a given page ( ProfilePage.java )
• WicketApplication.properties - for aplication-wide properties ( WicketApplication.java )

Wicket, when looking for properties for a given component, will look for the property files in the same order as above. AFAIR Struts2 uses exactly the same technic.

Please look at Wicket documentation: https://cwiki.apache.org/WICKET/i18n-and-resource-bundles.html .

Answer 3

As a last resort, you could write multiple files, but merge them into a single WicketApplication.properties as part of your build process. Unix has a tool precisely for doing this .
