使用jaxb 实现对象与xml之间的转换,并且是 soap报文与对象转换

1.测试用例

public class TestJaxb {
    @Test
    public void testToObject(){
         JaxbBinder jaxbBinder = new JaxbBinder(SoapEnvelope.class);


       URL url = this.getClass().getClassLoader().getResource("receB2COrderResponse.xml");
        String xml = null;
        try {
            xml = FileUtils.readFileToString(new File(url.getPath())) ;
        } catch (IOException e) {
            e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
        }

        SoapEnvelope envelope =jaxbBinder.fromXml(xml);

        Assert.notNull(envelope,"envelope数据为空");
        Assert.notNull(envelope.getBody(),"body数据为空");
        Assert.notNull(envelope.getBody().getReceB2COrderResponseList(),"body.list数据为空");
        Assert.notNull(envelope.getBody().getReceB2COrderResponseList().get(0),"body.list[0]数据为空");
        Assert.notNull(envelope.getBody().getReceB2COrderResponseList().get(0).getOrderNo(),"body.list[0]数据为空");
        System.out.println("getOrderNo="+envelope.getBody().getReceB2COrderResponseList().get(0).getOrderNo());

        System.out.println("ndata="+ (envelope).toString());


    }
    @Test
    public void testToXml(){
        ReceB2COrderRequest re = new ReceB2COrderRequest();
        re.setBuyerContact("test111123123");
        re.setBuyerId("asdfsadfasdf");
        re.setBuyerName("aaaaaaaaaaa");
        SoapBody body = new SoapBody();
        body.setReceB2COrderRequestList(Arrays.asList(re));

        SoapEnvelope envelope = new SoapEnvelope(null,body);

        JaxbBinder jaxbBinder = new JaxbBinder(SoapEnvelope.class);

        String xml =jaxbBinder.toXml(envelope,"utf-8");


        System.out.println("nxml="+ xml);


    }

3.XML报文实例(receB2COrderResponse.xml)

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
 <ns1:receiveB2COrderResponse xmlns:ns1="http://www.sdo.com/mas/api/receive/">
 <return>
 <customerName>爱奇艺</customerName>
 <customerNo>332396</customerNo>
 <orderAmount>30.00</orderAmount>
 <orderNo>2014081809451210442</orderNo>

 </ns1:receiveB2COrderResponse>
</soap:Body>
