概述：

利用eclipse link 中moxy在弄微信的向微信寫入資料。報錯了。。。。

[Exception [EclipseLink-25004] (Eclipse Persistence Services - 2.7.0.v20170701-882318f): org.eclipse.persistence.exceptions.XMLMarshalException
Exception Description: An error occurred unmarshalling the document
Internal Exception: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[8,500]

最後發現，微信需要編碼為gbk，而我設定為utf-8。

@Override
	public void textHandle(String data, HttpServletResponse response) throws JAXBException, IOException {
		JAXBContext unmarshJc = JAXBContext.newInstance(MsgTextReqDTO.class);
		JAXBContext marshJc = JAXBContext.newInstance(MsgTextRespDTO.class);

		Unmarshaller unmarshaller = unmarshJc.createUnmarshaller();
		MsgTextReqDTO msgTextReqDTO = (MsgTextReqDTO) unmarshaller.unmarshal(new StringReader(data));
		logger.info("Unmarshal: " +msgTextReqDTO.toString());
		
		Marshaller marshaller = marshJc.createMarshaller();
		marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
		marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true);
		marshaller.setProperty(Marshaller.JAXB_ENCODING, "utf-8");
		
		MsgTextRespDTO msgRespDTO = new MsgTextRespDTO();
		//======================硬編碼================
		msgRespDTO.setContent(msgTextReqDTO.getContent());
		msgRespDTO.setCreateTime(WeiXinUtil.createTimestamp());
		msgRespDTO.setFromUserName(msgTextReqDTO.getToUserName());
		msgRespDTO.setMsgType(msgTextReqDTO.getMsgType());
		msgRespDTO.setToUserName(msgTextReqDTO.getFromUserName());
		//marshaller.marshal(msgRespDTO, response.getOutputStream());
		marshaller.marshal(msgRespDTO, response.getOutputStream());
