在 Android 中为 ResourceBundle.getBundle(String path) 放置资源的位置？
Where to put resources in Android for ResourceBundle.getBundle(String path)?
我在我的 android 项目中使用了一个 ee-jars。它使用 ResourceBundle.getBundle(String path) 作为 i18n。由于资源在 jar 中被剥离，而 .apk 不包含资源，我遇到了一个异常：

我该怎么做才能修复它？我的想法是从 jar 中获取资源并将它们放入 Android 项目的 resources 文件夹中。它的正确位置在哪里？ Android 确实支持 ResourceBundle.getBundle(String path) (reference)，但没有写出资源的放置位置。
我不得不：
- 引入资源加载器接口(
WSS4JResourceBundle.ResourceBundleLoader)
- 引入静态资源加载器变量加载资源(
public static ResourceBundleLoader sharedLoader)
- 将使用
ResourceBundle.getBundle 的加载资源替换为静态 var 方法调用 (wss4jSecResourceBundle = sharedLoader.getBundle("messages.wss4j_errors"); f.e.)
- 创建默认值 (
DefaultResourceBundleLoader) 和 android 实现 (AndroidResourceBundleLoader)
- 重新打包资源到android的项目
assets文件夹
- 在应用程序启动时注入 android 实现而不是默认实现 (
WSS4JResourceBundle.sharedLoader = new AndroidResourceBundleLoader(ctx, "wss4j/");)
修改WSS4JResourceBundle:
package org.apache.wss4j.common.crypto;
import java.util.Enumeration;
import java.util.Locale;
import java.util.MissingResourceException;
import java.util.ResourceBundle;
import org.apache.xml.security.utils.Constants;
import org.apache.xml.security.utils.I18n;
/**

*/
public class WSS4JResourceBundle extends ResourceBundle {
/**
* Loader API
*/
public interface ResourceBundleLoader {
ResourceBundle getBundle(String path);
ResourceBundle getBundle(String baseName, Locale locale, ClassLoader loader);
}
// default
public static ResourceBundleLoader sharedLoader = new DefaultResourceBundleLoader();
/**
* Default IMPL
*/
public static class DefaultResourceBundleLoader implements ResourceBundleLoader {
@Override
public ResourceBundle getBundle(String path) {
return ResourceBundle.getBundle(path);
}
@Override
public ResourceBundle getBundle(String baseName, Locale locale, ClassLoader loader) {
return ResourceBundle.getBundle(baseName, locale, loader);
}
}
private static final org.slf4j.Logger LOG =
org.slf4j.LoggerFactory.getLogger(WSS4JResourceBundle.class);
private final ResourceBundle wss4jSecResourceBundle;
private final ResourceBundle xmlSecResourceBundle;
public WSS4JResourceBundle() {
wss4jSecResourceBundle = sharedLoader.getBundle("messages.wss4j_errors");
ResourceBundle tmpResourceBundle;
try {
tmpResourceBundle = sharedLoader.getBundle(
Constants.exceptionMessagesResourceBundleBase,
Locale.getDefault(),
I18n.class.getClassLoader());
} catch (MissingResourceException ex) {
// Using a Locale of which there is no properties file.
LOG.debug(ex.getMessage());
// Default to en/US
tmpResourceBundle =
sharedLoader.getBundle(Constants.exceptionMessagesResourceBundleBase,
new Locale("en", "US"), I18n.class.getClassLoader());
}
xmlSecResourceBundle = tmpResourceBundle;
}
@Override
protected Object handleGetObject(String key) {
Object value = null;
try {
value = wss4jSecResourceBundle.getObject(key);
} catch (MissingResourceException e) {
try {
value = xmlSecResourceBundle.getObject(key);
} catch (MissingResourceException ex) { //NOPMD
//ignore
}
}
return value;
}
@Override
public Enumeration<String> getKeys() {
throw new UnsupportedOperationException("getKeys not supported");
}
}
新 AndroidResourceBundleLoader:
package org.apache.wss4j.common.crypto;
import android.content.Context;
import android.content.res.AssetManager;
import com.splinex.streaming.Log;
import java.io.IOException;
import java.io.InputStream;
import java.util.Locale;
import java.util.PropertyResourceBundle;
import java.util.ResourceBundle;
public class AndroidResourceBundleLoader implements WSS4JResourceBundle.ResourceBundleLoader {
private static final String TAG = AndroidResourceBundleLoader.class.getSimpleName();
private String prefix;
private AssetManager manager;
public AndroidResourceBundleLoader(Context context, String prefix) {
manager = context.getAssets();
this.prefix = prefix;
}
@Override
public ResourceBundle getBundle(String path) {
try {
String fullPath = prefix + path.replace(".", "/") + ".properties";
return new PropertyResourceBundle(manager.open(fullPath));
} catch (IOException e) {
android.util.Log.e(TAG, "Failed to load " + path, e);
throw new RuntimeException(e);
}
}
@Override
public ResourceBundle getBundle(String path, Locale locale, ClassLoader classLoader) {
return getBundle(path + "_" + locale.getLanguage());
}
}
像这样注入 android 实现：
WSS4JResourceBundle.sharedLoader = new AndroidResourceBundleLoader(ctx, "wss4j/");
