### java发送soap请求和解析soap的响应 ###

*  一.soap请求报文
 *  二.soap响应报文
 *  三.代码实现
 *   *  1.引入对应jar
     *  2.代码实现

# 一.soap请求报文 #

<s:Envelope
        xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
        <s:Body>
            <GetPoints xmlns="http://tempuri.org/">
                <kunkun xmlns:d4p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
