读取资源绑定为UTF-8。 getString（）方法似乎将编码更改为ISO-8859 [英] read resourcebundle as UTF-8. getString() Method seems to change encoding to ISO-8859

问题描述

我有这个荣幸的任务是将完整的工作空间，项目和文件的编码改为UTF-8编码。我们有几个Resourcebundles用于使用unicode编码特殊字符。我们也想通过切换到UTF-8来摆脱这个unicode的东西，所以我更改了Resourcebundles（.properties）文件的编码，并替换了Unicode字符。

我们还有德国资源分类和一些字符，如

Ä，Ö，Ü，ß。 ä，ö，ü以及特殊字符如或

在浏览器中未正确显示。例如：

Resourcebundleentry：

executeShellCommand.label = Shellkommandoausführen

浏览器中的结果：

资源绑定使用Java.util.ResourceBundle.getString（String key）读取方法：

  public String getLocalizedString（ResourceBundle bundle，String key）{
 try {
 System.out.println（getLocalizedString，key：+键+，resourcebundle：+ bundle.getString（key））; 
 return bundle.getString（key）; 
} catch（MissingResourceException e）{
 return key; 
} 
} 
  

如果我检查上面的Sysout的输出，我得到以下：
getLocalizedString，key：executeShellCommand.label，resourcebundle：Shellkommandoausführen


看起来， getString（key）方法可以从包中读取从标准资源编码（ISO-8859）中更改字符的编码。

我试图解决这个问题：

  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; 
} 
} 
  

这有助于恢复最特别的字符，但有仍然有很多他们没有正确显示：

我还检查了WebApp的内容类型配置以及获取资源束的每个请求，一切都是utf-8。有没有人有一个想法如何阻止getString（） - 方法更改编码还是有更好的方法来解决这个问题？ / p>

解决方案

Java ResourceBundles假定ISO-8859。我想你需要使用Properties而不是ResourceBundle。

  InputStream utf8in = getClass（）。getClassLoader（）。getResourceAsStream /path/to/utf8.properties）; 
读者阅读器=新的InputStreamReader（utf8in，UTF-8）; 
属性props = new Properties（）; 
 props.load（reader）; 
  

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.

We also have german resourcebundles and some chars like

Ä, Ö, Ü, ß. ä, ö, ü and also special characters like „ or "

are not shown properly in the browser. Example:

Resourcebundleentry:

executeShellCommand.label = Shellkommando ausführen

Result in browser:

The resourcebundles are read with the Java.util.ResourceBundle.getString(String key) Method:

    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 ausführen

It seems that the getString(key) method changes the encoding of the chars while reading them from the bundles to the standard resourcbundleencoding(ISO-8859).

I tried to counter this issue:

    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:

I also checked the content-type configuration of the WebApp and of every single request which gets the resource bundles everything is utf-8.

Does anyone have an idea how to prevent the getString()-Method from changing the encoding or is there a better way to solve this issue?

解决方案

Java ResourceBundles assume ISO-8859. I think you'll need to use Properties instead of ResourceBundle.

InputStream utf8in = getClass().getClassLoader().getResourceAsStream("/path/to/utf8.properties");
Reader reader = new InputStreamReader(utf8in, "UTF-8");
Properties props = new Properties();
props.load(reader);
