ssh接收和返回xml

Struts中配置：

action中：

public String Weixin_Notify() {
HttpServletRequest request = getHttpServletRequest();
HttpServletResponse response = ServletActionContext.getResponse();

Map<String, String> params = PayNotify.parseXml(request
.getInputStream());//获得xml并解析

String WEIXIN_RETURN = "<xml><return_code>SUCCESS</return_code><return_msg>OK</return_msg></xml>";

// 把xml字符串写入响应
    byte[] xmlData = WEIXIN_RETURN.getBytes();
    response.setContentType("text/xml;charset=utf-8");
    response.setHeader("Cache-Control", "no-cache");
    response.setContentLength(xmlData.length);
    PrintWriter os = response.getWriter();
    os.write(WEIXIN_RETURN);

······

return SUCCESS；}
