开发的微信公众号，启用了客服功能，粉丝发来信息的时候，客服接入前，只可以收到文字信息，收不到图片信息，在客服收入后，才可以收到粉丝发来的图片信息

private String toCustomer(String toUserName,String openid){
    //String toUserName = "TO_USER_NAME";
    //String openid = "OPEN_ID";
    String responseMessage = "success";
    TextMessage textMessage = new TextMessage();
    textMessage.setToUserName(openid);
    textMessage.setFromUserName(toUserName);
    textMessage.setCreateTime(new Date().getTime());
    //textMessage.setMsgType(WeChatUtil.RESP_MESSAGE_TYPE_TEXT);
    String text = "接入人工客服......";
    textMessage.setContent(text);
    textMessage.setMsgType("transfer_customer_service");
    responseMessage = WeChatUtil.textMessageToXml(textMessage);
    logger.info(responseMessage + "=========");
    //responseMessage = responseMessage.replace("TO_USER_NAME", toUserName).replace("OPEN_ID", openid);
    return responseMessage;
