从 Struts 2.3.33 迁移到 Struts 2.5.12 LocalizedTextUtil 被移除

2022-01-16 00:00:00 migration localization java struts2

我们尝试从 Struts 2.33 迁移到 Struts 2.5.12.

We tried to migrate from Struts 2.33 to Struts 2.5.12.

我们在应用程序中直接使用了LocalizedTextUtil.

We used LocalizedTextUtil in our application directly.

我发现 LocalizedTextUtil 已从 com.opensymphony.xwork2.util.LocalizedTextUtil 中删除.我试图搜索但找不到任何东西

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

我发现了一些类，如 StrutsLocalizedTextProvider 和 GlobalLocalizedTextProvider 但似乎它们不是我可以使用的.

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

我已查看 migration-guide，但找不到任何关于它.

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

有什么选择?

推荐答案

struts.xml应该设置为:

The struts.xml should be set as:

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

并且 CustomStrutsTextProviderFactory 可以添加捆绑包

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);
}

}
