Migrate from Struts 2.3.33 to Struts 2.5.12 LocalizedTextUtil is removed

We tried to migrate from Struts 2.33 to Struts 2.5.12.

We used LocalizedTextUtil in our application directly.

I found that the LocalizedTextUtil is removed from com.opensymphony.xwork2.util.LocalizedTextUtil. I tried to search but could not find any thing

I found some classes like StrutsLocalizedTextProviderand GlobalLocalizedTextProvider but it seems they are not what I can use them.

I have reviewed migration-guide but could not find any comment about it.

Which alternative is there?

Solution

  • The struts.xml should be set as:

    <constant name="struts.xworkTextProvider" value="DefaultTextProvider" />
<bean type="com.opensymphony.xwork2.TextProvider" name="DefaultTextProvider" class="utils.MyTextProviderFactory" scope="default" />

    And CustomStrutsTextProviderFactory could add bundles

    public class MyTextProviderFactory implements TextProviderFactory {

protected LocaleProviderFactory localeProviderFactory;
protected LocalizedTextProvider localizedTextProvider;

@Inject
public MyTextProviderFactory(LocaleProviderFactory localeProviderFactory, LocalizedTextProvider localizedTextProvider) {
    this.localeProviderFactory = localeProviderFactory;
    this.localizedTextProvider = localizedTextProvider;
    
    this.localizedTextProvider.addDefaultResourceBundle("messages/label");
    this.localizedTextProvider.addDefaultResourceBundle("messages/customerA/label");
    
}

@Override
public TextProvider createInstance(Class clazz) {
    TextProvider instance = getTextProvider(clazz);
    if (instance instanceof ResourceBundleTextProvider) {
        ((ResourceBundleTextProvider) instance).setClazz(clazz);
        ((ResourceBundleTextProvider) instance).setLocaleProvider(localeProviderFactory.createLocaleProvider());
    }
    return instance;
}

@Override
public TextProvider createInstance(ResourceBundle bundle) {
    TextProvider instance = getTextProvider(bundle);
    if (instance instanceof ResourceBundleTextProvider) {
        ((ResourceBundleTextProvider) instance).setBundle(bundle);
        ((ResourceBundleTextProvider) instance).setLocaleProvider(localeProviderFactory.createLocaleProvider());
    }
    return instance;
}

protected TextProvider getTextProvider(Class clazz) {
    return new TextProviderSupport(clazz, localeProviderFactory.createLocaleProvider(), localizedTextProvider);
}

protected TextProvider getTextProvider(ResourceBundle bundle) {
    return new TextProviderSupport(bundle, localeProviderFactory.createLocaleProvider(), localizedTextProvider);
}

    }
