码头响应字符编码

Jetty文档声称它默认情况下使用UTF-8，但这似乎是一个谎言。如果执行normal

response.getWrite().println("Hello")

1. 从content-type到content-encoding的默认映射是从加载的

   org/eclipse/jetty/http/encoding.properties

   ：

       // MimeTypes.java:155    ResourceBundle encoding = ResourceBundle.getBundle("org/eclipse/jetty/http/encoding");    Enumeration<String> i = encoding.getKeys();    while(i.hasMoreElements())    {        String type = i.nextElement();        __encodings.put(type,encoding.getString(type));    }

默认文件是：

text/html   = ISO-8859-1text/plain  = ISO-8859-1text/xml    = UTF-8text/json   = UTF-8

1. Response.getWriter()

   尝试使用该地图，但默认为ISO-8859-1

   @Override
   public PrintWriter getWriter() throws IOException
   {
   if (_outputType == OutputType.STREAM)
   throw new IllegalStateException(“STREAM”);
   
   

   if (_outputType == OutputType.NONE){        String encoding = _characterEncoding;    if (encoding == null)    {        encoding = MimeTypes.inferCharsetFromContentType(_contentType);        if (encoding == null) encoding = StringUtil.__ISO_8859_1;        setCharacterEncoding(encoding);    }

因此，您可以看到

text/html

encoding.properties

text/html   = UTF-8text/plain  = UTF-8text/xml    = UTF-8text/json   = UTF-8

但是即使这样，即使找到的编码也不存在，它也会默认为ISO-8859-1。
