How to set a resource bundle location in Struts 2?

I currently have a package on my classpath called MyResources with multiple property files that Struts uses. Works great:

<constant name="struts.custom.i18n.resources" value="com.company.MyResources"/>

I am trying to move the properties files to a file location, so they can be updated without having to rebuild the package. Is it possible in Struts 2 to refer to this file location?

For example, my new location with the properties files is:

/g01/properties/

And I would like Struts to use that location for the resources.

Solution

  • Yes, by providing an implementation of ResourceBundleTextProvider and initializing it in your struts.xml configuration file.

    The default implementation, com.opensymphony.xwork2.TextProviderSupport defers the text lookup to com.opensymphony.xwork2.util.LocalizedTextUtil.

    There are a number of ways to go about this, but if you don't need any of the default S2 behavior, here's the place to start:

    <bean type="com.opensymphony.xwork2.TextProvider" name="struts" 
      class="com.opensymphony.xwork2.TextProviderSupport" scope="default" />

    Provide your own ResourceBundleTextProvider implementation that uses whatever configuration management you want, for example, we implemented a DB-backed version (with caching, of course) that allowed translations to live in, and be managed by, a normal DB and I18N front end.

    I'll see if I can dig up my original work this weekend and provide a link to a stripped-down solution.
