请教我新生成了xml,用stringbuffer写入xml文件.但是写后前面有乱码.

Question

FileOutputStream   fo = null;   
        DataOutputStream   ds = null;
        
        OutputStreamWriter osw = null;
        
    
  try{   
          fo   =   new   FileOutputStream(Common.strSLExtXMLWritePath+"lists"+xmlURL);   //set   output   file   path   and   name.   
          ds   =   new   DataOutputStream(fo);   
          //osw =   new   OutputStreamWriter(fo);
            
          ds.writeUTF(StrXMl.toString());
          //osw.write(StrXMl.toString());
          System.out.println(Common.strSLExtXMLWritePath+"lists"+xmlURL);
          //System.out.println("@@@System.out.osw"+osw.getEncoding());
          
          //osw.flush();
          //osw.close();
          ds.flush();   
          ds.close();   
          fo.close();   
  }catch(Exception ex){
  ex.printStackTrace();
  }
这是我写的代码.怎么会前面头有乱码?请指教.

Answer 1

byte[] nbs=StrXMl.toString().getBytes();
fo.write(nbs);

Answer 2

OutputStream   fo = null;   
        DataOutputStream   ds = null;
        FileWriter fw= null;
        OutputStreamWriter osw = null;
        
    
        try{   
          fo   =   new   FileOutputStream(Common.strSLExtXMLWritePath+"lists"+xmlURL);   //set   output   file   path   and   name.   
          osw =   new   OutputStreamWriter(fo,"UTF-8");
          BufferedWriter bfw=new BufferedWriter(osw);
          bfw.write(new String(StrXMl.toString().getBytes("UTF-8"),"UTF-8"));
          System.out.println(Common.strSLExtXMLWritePath+"lists"+xmlURL);
          bfw.flush();
          bfw.close();
          fo.close();   
        }catch(Exception ex){
         ex.printStackTrace();
        }
可以已经

Answer 3

bfw.write(StrXMl.toString().getBytes("UTF-8"));
好像只用写的时候指定编码就可以了
