dom4j生成xml乱码问题

写道

/** 研发部提供发布信息接口 */
@RequestMapping("/getPublishTypeList.shtml")
public void getPublishTypeList(ModelMap model, HttpServletRequest request,
HttpServletResponse response) throws Exception {
response.setContentType("text/xml;charset=gbk");
PrintWriter pWriter=response.getWriter();
pWriter.flush();
String unitUserID = request.getParameter("unitID");
UnitUser unitUser = ddlibService.getUnitUserByUnitUserID(unitUserID);
List<PublishType> publishTypes = publishService.getPublishTypeList(unitUserID);
Document document = DocumentHelper.createDocument();
Element publishType = document.addElement("PublishType");
Element unitID = publishType.addElement("UnitID");
unitID.addText(unitUserID);
Element unitName = publishType.addElement("UnitName");
unitName.addText(unitUser.getUserName());

String url = "http://"+unitUser.getUnitDomain()+"/ddlib/getPublishInfoList.shtml?tid=";
Element types = publishType.addElement("Types");
if(publishTypes != null && publishTypes.size()>0){
for(PublishType type : publishTypes){
Element typeName = types.addElement("TypeName");
typeName.addText(type.getTypeName());
Element URL = types.addElement("URL");
URL.addText(url+type.getId());
}
}

XMLWriter writer = null;
OutputFormat format = OutputFormat.createPrettyPrint();
/** 指定XML编码 */
format.setEncoding("GBK");
writer= new XMLWriter(response.getWriter(),format);
writer.write(document);
writer.println();
writer.flush();
// pWriter.println(document.asXML());这个是刚开始的方法 无法正常显示
}

 使用dom4j生成的xml在firefox,opera,chrome下都正常显示,在ie下无法正常显示,后来发现是中文问题,虽然没有乱码.
