系统之间接口访问

对于外部系统发布的webservice接口WSDL。可使用HTTP请求方式去访问。

/**
	 * http post请求
	 * @param urlString 请求地址
	 * @param soapXML xml字符串
	 * @return
	 */
    public static String HttpPostRequest(String urlString , String soapXML){
        String result = "";

            //1：创建服务地址

            //2：打开到服务地址的一个连接
            connection = (HttpURLConnection) url.openConnection();
            //3：设置连接参数
            //3.1设置发送方式：POST必须大写
            connection.setRequestMethod("POST");
            //3.2设置数据格式：Content-type
            connection.setRequestProperty("content-type", "text/xml;charset=UTF-8");
            //3.3设置输入输出，新创建的connection默认是没有读写权限的，
            connection.setDoInput(true);
            connection.setDoOutput(true);
            connection.connect();//打开到此 URL 引用的资源的通信链接
