Javaはオブジェクトをオブジェクト

Question

I tried to unmarshall following xml file. 

<ns2:Triggermessage xmlns="http://www.asd.com/messaging" xmlns:ns2="http://www.asd.com/messaging/closing/trigger"> 
    <Header> 
    <creationTimeStamp>2017-05-23T12:11:46.950+00:00</creationTimeStamp> 
    <businessDate>2017-05-23</businessDate> 
    <messageId>20170523-22:30:00_Calypso Rpt 7_444_0</messageId> 
    <conversationId>7397dbd3-5177-40ff-acb5-1b2ba8d0d1f6</conversationId> 
    <numberOfRecords>1</numberOfRecords> 
    <sentBy>ABCDE</sentBy> 
    <sendto>Camplico</sendto> 
    <processingCycle>ACD</processingCycle> 
    </Header> 
    <ns2:Request> 
    <ns2:ProcessingCircle>EOD</ns2:ProcessingCircle> 
    </ns2:Request> 
</ns2:Triggermessage> 

Here I created classes in this way.(not all the classes are mentioned here) 

**TriggerMessage.java** 
@XmlRootElement(name = "TriggerMessage", namespace="http://www.asd.com/messaging/closing/trigger") 
    public class TriggerMessage { 

     private Header header; 
     private Request request; 

     @XmlElement(name = "Header") 
     public Header getHeader() { 
      return header; 
     } 
     public void setHeader(Header header) { 
      this.header = header; 
     } 

     @XmlElement(name = "Request") 
     public Request getRequest() { 
      return request; 
     } 
     public void setRequest(Request request) { 
      this.request = request; 
     } 
    } 

**Header.java** 
private CreationTimeStamp creationTimeStamp; 
    private BusinessDate businessDate; 
    private MessageId messageId; 
    private ConversationId conversationId; 
    private SentBy sentBy; 
    private SendTo sendTo; 
    private ProcessingCycle processingCycle; 
    private NumberOfRecords numberOfRecords; 
@XmlElement(name = "creationTimeStamp") 
public CreationTimeStamp getCreationTimeStamp() { 
    return creationTimeStamp; 
} 
public void setCreationTimeStamp(CreationTimeStamp creationTimeStamp) { 
    this.creationTimeStamp = creationTimeStamp; 
} 

@XmlElement(name = "businessDate") 
public BusinessDate getBusinessDate() { 
    return businessDate; 
} 
public void setBusinessDate(BusinessDate businessDate) { 
    this.businessDate = businessDate; 
} 

@XmlElement(name = "conversationId") 
public ConversationId getConversationId() { 
    return conversationId; 
} 
public void setConversationId(ConversationId conversationId) { 
    this.conversationId = conversationId; 
} 

@XmlElement(name = "messageId") 
public MessageId getMessageId() { 
    return messageId; 
} 
public void setMessageId(MessageId messageId) { 
    this.messageId = messageId; 


} 
- 
- 
-} 

**CreationTimeStamp.java** 

public class CreationTimeStamp { 

     private String value; 

     @XmlMixed 
     public String getValue() { 
      return value; 
     } 
     public void setValue(String value) { 
      this.value = value; 
     } 
    } 

    **Request.java** 

@XmlType(namespace="http://www.asd.com/messaging/closing/trigger") 
public class Request { 

    private ProcessingCircle processingCircle; 

    @XmlElement(name = "processingCircle") 
    public ProcessingCircle getProcessingCircle() { 
     return processingCircle; 
    } 
    public void setProcessingCircle(ProcessingCircle processingCircle) { 
     this.processingCircle = processingCircle; 
    } 
} 

に複雑なXMLをアンマーシャルとなりましたpackage-info.javaファイルはこちら。

これは、私は、XSDにXMLを変換し

private List<Object> unMarshalMessages(List<String> messages) { 
     List<Object> messageObjects = new ArrayList<Object>(); 
     JAXBContext context = null; 
     try { 
      context = JAXBContext.newInstance(Class.forName("com.msgs.calpico.TriggerMessage")); 
      Unmarshaller m = context.createUnmarshaller(); 
      StringReader reader = null; 
      for (String message : messages) { 
       reader = new StringReader(message); 
      messageObjects.add(((com.msgs.calpico.TriggerMessage) m.unmarshal(reader))); 
      } 

     } catch (JAXBException e) { 
      e.printStackTrace(); 
     } catch (ClassNotFoundException e) { 
      e.printStackTrace(); 
     } 
     LOGGER.info("After unmarshal the output messages size: " + messageObjects.size()); 
     return messageObjects; 
    }

を非整列化するために使用されるコードです。 その後、Eclipseを使用して、jaxbプロジェクトを作成し、xsdをポイントします。 javaファイルはxsdファイルに基づいて生成されます。

Javaスキーマファイルが生成されると、marshallおよびunmarsahllコードを使用できます。

プライベートstatic JAXBContext _jaxbContext;

static 
{ 
    ClassLoader cl = Thread.currentThread().getContextClassLoader(); 
    try 
    { 
     Thread.currentThread().setContextClassLoader(Connection.class.getClassLoader()); //NOPMD. 

     StringBuffer sb = new StringBuffer(); 
     sb.append("com.microsoft.schemas.windowsazurerm"); //schema package name 
     _jaxbContext = JAXBContext.newInstance(sb.toString()); 
    } 
    catch (Exception e) 
    { 
     logger.error(e); 
    } 
    finally 
    { 
     Thread.currentThread().setContextClassLoader(cl); 
    } 
} 

Unmarshaller unmarshaller; オブジェクトオブジェクト= null; try { unmarshaller = context.createUnmarshaller（）; オブジェクト= unmarshaller.unmarshal（新しいStreamSource（新しいStringReader（xml）））; }
