老问题，xml乱码

Question

servlet里 一个BufferedOutputStream 流 输出xml格式的字符。encoding="UTF-8" 的时候汉字浏览器显示乱码
encoding="gb2312" 的时候汉字显示正常 但是我需要一个UTF-8的格式的文件。于是我在拼接的时候，对汉字进行硬转码 
name = new String(name.getBytes("GBK"),"UTF-8");
....
或者这样
name = new String(name.getBytes("UTF-8"),"GBK");类似这样的转码一个个的都试了试，全部不行求方案。。

Answer 1

程序很简单了，就是拼接了个xml串
然后弄一个BufferedOutputStream
os.write(xml.getBytes());
浏览器查看

Answer 2

程序很简单了，就是拼接了个xml串 
然后弄一个BufferedOutputStream 
os.write(xml.getBytes()); 

Answer 3

答:楼主的对汉字进行硬转码 
name = new String(name.getBytes("GBK"),"UTF-8"); 
.... 
或者这样 
name = new String(name.getBytes("UTF-8"),"GBK"); 两种写法都是错误的.
设String xml="你好!";
则转成UTF-8的字节数据,就是:
弄一个BufferedOutputStream 
os.write(xml.getBytes("UTF-8")); 就行了.为何弄得那么复杂?

Answer 4

    Document document = DocumentHelper.parseText(xml);
   OutputFormat format = OutputFormat.createPrettyPrint();
         format.setEncoding("utf-8");           
         XMLWriter writer = new XMLWriter(new FileOutputStream("test.xml"),format);
 writer.write(document);
writer.close();不知道行不行，楼主该帖代码出来

Answer 5

name = new String(name.getBytes("UTF-8"),"gb2312");

        try {

            byte[] utfByte=utfBytes.array();
            String s=new String(utfByte,"UTF-8");
            System.out.println(s);
            return s;
        } catch (UnsupportedEncodingException ex) {
            ex.printStackTrace();
            return string;
        } catch (CharacterCodingException ex) {
            ex.printStackTrace();
            return string;
        }
    }
  //
 public String utf8Togbk(String string){
   Charset asciiCharset=Charset.forName("Unicode");
        decord=asciiCharset.newDecoder();
        Charset  utfCharset= Charset.forName("GBK");

        ByteBuffer  utfBytes=null;
        CharBuffer  helpChars=null;
        try {
          //String GBKinfo = new String("hello你好~@_@~123".getBytes("UTF-8"), "UTF-8");

            return string;
        } catch (CharacterCodingException ex) {

        }
 }   你试看看行不行,我测试是可以的哈,
