JAXB XML与对象之间转换

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);


    }

2.转换工具

import javax.xml.bind.*;
import javax.xml.namespace.QName;
import java.io.File;
import java.io.InputStream;
import java.io.StringReader;
import java.io.StringWriter;
import java.util.Collection;

		try {
			jaxbContext = JAXBContext.newInstance(types);
		} catch (JAXBException e) {
			throw new RuntimeException(e);
		}
	}

	/**
	 * Java Object->Xml.
	 */
	public String toXml(Object root,String encoding) {
		try {
			StringWriter writer = new StringWriter();
			createMarshaller(encoding).marshal(root,writer);
			return writer.toString();
		} catch (JAXBException e) {
			throw new RuntimeException(e);
		}
	}

	/**
	 * Java Object->Xml,特别支持对Root Element是Collection的情形.
	 */
	@SuppressWarnings("unchecked")

	@SuppressWarnings("unchecked")
	public <T> T fromXml(String xml) {
		try {
			StringReader reader = new StringReader(xml);
			return (T) createUnmarshaller().unmarshal(reader);
		} catch (JAXBException e) {
			throw new RuntimeException(e);
		}
	}

	/**
	 * 创建Marshaller,设定encoding(可为Null).
	 */
	public Marshaller createMarshaller(String encoding) {
		try {

	}

	}

	/**

	 */
	public static class CollectionWrapper {
		@SuppressWarnings("unchecked")

	}


    @SuppressWarnings("unchecked")
    public <T> T fromXML(String fileName) {
        return (T)fromXML(new File(fileName));
    }


    @SuppressWarnings("unchecked")

        } catch (JAXBException e) {
            throw new RuntimeException(e);
        }
    }

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>
 <orderType>OT001</orderType>
 <returnInfo/>
 <sessionId>72041119-5d40-42dc-afec-980cbf0122a4</sessionId>
 <signature/>
 <tokenId>4A8A8F14C3BED9151F51C0096319A664AAFD91E5B2982EAB21DDE8C557FC5A52B887E8CBF9AE3B19</tokenId>
 <transNo>C20140818094536462081</transNo>
 <transStatus>00</transStatus>
 <transTime>20140818094518</transTime>
 </return>
 </ns1:receiveB2COrderResponse>
</soap:Body>
</soap:Envelope>

4.testToXml()输出的报文内容:

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
                  xmlns:rec="http://www.sdo.com/mas/api/receive/">

            </arg0>
        </rec:receiveB2COrder>
    </soapenv:Body>
</soapenv:Envelope>
