read resourcebundle as UTF-8. getString() Method seems to change encoding to ISO-8859
提问by izocan
I have the honorable assignment to change the encoding of our complete workspace, projects and files to the UTF-8 encoding. We have several Resourcebundles which used to code special chars with unicode. We also wanted to get rid of that unicode stuff by switching to UTF-8 so I changed the encoding of the Resourcebundles (.properties) files too and replaced the Unicode characters.
我有一项光荣的任务，将我们整个工作区、项目和文件的编码更改为 UTF-8 编码。我们有几个 Resourcebundle，用于使用 unicode 编码特殊字符。我们还想通过切换到 UTF-8 来摆脱那些 unicode 的东西，所以我也更改了 Resourcebundles (.properties) 文件的编码并替换了 Unicode 字符。
We also have german resourcebundles and some chars like
我们还有德国资源包和一些字符，比如
?, ?, ü, ?. ?, ?, ü and also special characters like ? or “
?, ?, ü, ?. ?, ?, ü 以及特殊字符，如 ? 或者 ”
are not shown properly in the browser. Example:
未在浏览器中正确显示。例子：
Resourcebundleentry:
资源包入口：
executeShellCommand.label = Shellkommando ausführen
executeShellCommand.label = Shellkommando ausführen
Result in browser:
结果在浏览器中：
The resourcebundles are read with the Java.util.ResourceBundle.getString(String key) Method:
使用 Java.util.ResourceBundle.getString(String key) 方法读取资源包：
public String getLocalizedString(ResourceBundle bundle, String key) {
try {
System.out.println("getLocalizedString, key: " + key + ", resourcebundle: " + bundle.getString(key));
return bundle.getString(key);
} catch (MissingResourceException e) {
return key;
}
}
If i check the output of the above Sysout i get following:
getLocalizedString, key: executeShellCommand.label, resourcebundle: Shellkommando ausf??hren
如果我检查上述 Sysout 的输出，我会得到以下信息：
getLocalizedString, key: executeShellCommand.label, resourcebundle: Shellkommando ausf??hren
It seems that the getString(key) method changes the encoding of the chars while readingthem from the bundles to the standard resourcbundleencoding(ISO-8859).
似乎getString(key) 方法在从包中读取字符时将字符的编码更改为标准 resourcbundleencoding(ISO-8859)。
I tried to counter this issue:
我试图反驳这个问题：
public String getLocalizedString(ResourceBundle bundle, String key) {
try {
System.out.println("getLocalizedString, key: " + key + ", resourcebundle: " + new String (bundle.getString(key).getBytes(), "UTF-8"));
return new String (bundle.getString(key).getBytes(), "UTF-8");
} catch (MissingResourceException e) {
return key;
} catch (UnsupportedEncodingException e) {
return key;
}
}
This helped to recover the most special characters but there are still a plenty of them which are not shown properly:
这有助于恢复最特殊的字符，但仍有很多未正确显示：
I also checked the content-type configuration of the WebApp and of every single request which gets the resource bundles everything is utf-8.
我还检查了 WebApp 和每个获取资源包的请求的内容类型配置，一切都是 utf-8。
Does anyone have an idea how to prevent the getString()-Method from changing the encodingor is there a better way to solve this issue?
有没有人知道如何防止 getString()-Method 更改编码，或者有没有更好的方法来解决这个问题？

Java ResourceBundles assume ISO-8859. I think you'll need to use Properties instead of ResourceBundle.
Java ResourceBundles 采用 ISO-8859。我认为您需要使用 Properties 而不是 ResourceBundle。
InputStream utf8in = getClass().getClassLoader().getResourceAsStream("/path/to/utf8.properties");
Reader reader = new InputStreamReader(utf8in, "UTF-8");
Properties props = new Properties();
props.load(reader);

How's this for a hack!!!
这对黑客来说如何！！！
public class HackClassLoader extends ClassLoader {
public HackClassLoader(ClassLoader parent) {
super(parent);
}
@Override
public InputStream getResourceAsStream(String name) {
InputStream utf8in = getParent().getResourceAsStream(name);
if (utf8in != null) {
try {
byte[] utf8Bytes = new byte[utf8in.available()];
utf8in.read(utf8Bytes, 0, utf8Bytes.length);
byte[] iso8859Bytes = new String(utf8Bytes, "UTF-8").getBytes("ISO-8859-1");
return new ByteArrayInputStream(iso8859Bytes);
} catch (IOException ex) {
throw new RuntimeException("Could not load " + name, e);
} finally {
utf8in.close();
}
}
return null;
}
}
ClassLoader hackLoader = new HackClassLoader(getClass().getClassLoader());
ResourceBundle bundle = ResourceBundle.getBundle("foo", Locale.UK, hackLoader);
