为什么从ResourceBundle.getBundle中检索字符串时难以理解的字符

请告诉我如何解决这个问题：

Locale locale = new Locale(language); ResourceBundle messages = ResourceBundle.getBundle("i18n.messages", locale, utf8Control); try { String message = new String(messages.getString(key).getBytes("ISO-8859-1"), "UTF-8"); pageContext.getOut().write(message); } catch (IOException e) { e.printStackTrace(); } 

我正在尝试实现本地化，我从创建的消息文件中获取文本，问题是，而不是必要的字符，它输出“?????? ??????? ????” 谷歌搜索，问题似乎是编码，我试图这样做：

 String message = new String(messages.getString(key).getBytes("ISO-8859-1"), "UTF-8") 

还创建了utf8Control：

 public class Utf8Control extends ResourceBundle.Control { @Override public ResourceBundle newBundle(String baseName, Locale locale, String format, ClassLoader loader, boolean reload) throws IllegalAccessException, InstantiationException, IOException { String bundleName = toBundleName(baseName, locale); String resourceName = toResourceName(bundleName, "properties"); ResourceBundle bundle = null; InputStream stream = null; if (reload) { URL url = loader.getResource(resourceName); if (url != null) { URLConnection connection = url.openConnection(); if (connection != null) { connection.setUseCaches(false); stream = connection.getInputStream(); } } } else { stream = loader.getResourceAsStream(resourceName); } if (stream != null) { try { bundle = new PropertyResourceBundle(new InputStreamReader(stream, "UTF-8")); } finally { stream.close(); } } return bundle; } } 

什么都没发生…… JSP有“UTF-8”编码，文件 – 默认为“ISO-8859-1”
