java sends soap request and parses soap response

1. soap request message

<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">
            	<!-- 下面是需要传的四个参数 -->
                <d4p1:string>chang</d4p1:string>  
                <d4p1:string>tiao</d4p1:string>  
                <d4p1:string>rap</d4p1:string>  
                <d4p1:string>basketball</d4p1:string>                
            </kunkun>
        </GetPoints>
    </s:Body>
</s:Envelope>

2. soap response message

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body>
        <GetPointsResponse xmlns="http://tempuri.org/">
            <GetPointsResult xmlns:a="http://schemas.datacontract.org/2004/07/XDB.DataServiceInterface" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
                <a:Data>
                    <a:Name>张三</a:Name>
                    <a:LikeYear>2.5年</a:LikeYear>        
                </a:Data>
                <a:Data>
                    <a:Name>李四</a:Name>
                    <a:LikeYear>2.5年</a:LikeYear>        
                </a:Data>
                <a:Data>
                    <a:Name>王二</a:Name>
                    <a:LikeYear>2.5年</a:LikeYear>        
                </a:Data>
                <a:Data>
                    <a:Name>麻子</a:Name>
                    <a:LikeYear>2.5年</a:LikeYear>        
                </a:Data>
            </GetPointsResult>
        </GetPointsResponse>
    </s:Body>
</s:Envelope>

3. Code implementation

1. Introduce the corresponding jar

   <dependency>
	   <groupId>dom4j</groupId>
	   <artifactId>dom4j</artifactId>
    </dependency>

2. Code implementation
