Java JAXB Marshalling / UnMarshalling

Java JAXB Marshalling / UnMarshalling

1. Marshalling (POJO to xml)

• Value Object Class

  @Setter  
  @XmlRootElement  
  public class TestValue {  
   @XmlElement  
  public String name;  
   @XmlElement  
  public int age;  
  }

• Marshalling

  TestValue testValue = new TestValue();  
  testValue.setAge(30);  
  testValue.setName("name");  
  JAXBContext context = JAXBContext.newInstance(TestValue.class);  
  Marshaller marshaller = context.createMarshaller();  
  marshaller.marshal(testValue, new File("test.xml"));

• 위에서 생성한 test.xml 파일의 내용

  <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
  <testValue>
   <name>name</name>
   <age>30</age>
  </testValue>

• Unmarshalling ( xml to POJO)

  TestValue testValue = new TestValue();  
  testValue.setAge(30);  
  testValue.setName("name");  
  File file = new File("test.xml");  
  JAXBContext context = JAXBContext.newInstance(TestValue.class);  
  Unmarshaller unmarshaller = context.createUnmarshaller();  
  TestValue testObject = (TestValue) unmarshaller.unmarshal(file);
