XStream将xml文件拼成字符串

 

1.引入的包  

<dependency>
<groupId>com.thoughtworks.xstream</groupId>
<artifactId>xstream</artifactId>
<version>1.4.7</version>
</dependency>

2.代码如下

import java.util.List;
import com.thoughtworks.xstream.annotations.XStreamAlias;
import com.thoughtworks.xstream.annotations.XStreamImplicit;

@XStreamAlias("OrderHeader")
public class FirstXml {
//    <Receiver></Receiver>收件人
//    <ReceiverEmail></ReceiverEmail>电子邮箱
//    <ReceiverPhone></ReceiverPhone>手机号
//    <OrderLineItem>
//  <Sequencenum>1</Sequencenum> 兑换顺序号
//      <ProductCode>A</ProductCode>礼品ID
//      <Points>2000</Points>积分分数
//      <QuantityRequested>1</QuantityRequested>数量
//      <PointType>Point</PointType>分数类型
//    </OrderLineItem>
//    <OrderLineItem>
//  <Sequencenum>2</Sequencenum> 兑换顺序号
//      <ProductCode>B</ProductCode>礼品ID
//      <Points>3000</Points>积分分数

    }
    
    
}

import java.util.ArrayList;
import java.util.List;
import com.thoughtworks.xstream.XStream;

public class Test {
    private static XStream xstream = null;

    public static void main(String[] args) {
        xstream = new XStream();
        
        FirstXml  firstXml  = new FirstXml ();

        firstXml.setReceiver("张三");//姓名
        firstXml.setReceiverEmail("123@qq.com");//邮编
        firstXml.setReceiverPhone("13340118888");//电话号码
        
        List<TwoXml> aaa = new ArrayList<TwoXml>();
        
        TwoXml twoXml01=new TwoXml();
        twoXml01.setSequencenum(1);
        twoXml01.setProductCode("A");
        twoXml01.setPoints("2000");
        twoXml01.setQuantityRequested(1);
        twoXml01.setPointType("Point");
        aaa.add(twoXml01);
        
        TwoXml twoXml02=new TwoXml();
        twoXml02.setSequencenum(2);
        twoXml02.setProductCode("B");
        twoXml02.setPoints("3000");
        twoXml02.setQuantityRequested(1);
        twoXml02.setPointType("Point");
        aaa.add(twoXml02);

        firstXml.setOrderLineItem(aaa);
        
        xstream.processAnnotations(FirstXml.class);
        String inputXml = xstream.toXML(firstXml);
       System.out.println(inputXml);
        
        
        
    }
}

3.运行结果如下图所示
