Import .This topic describes how a REST method created by the REST Creation In the following example, we are defining the methods beforeMarshal() and afterMarshal() that will be invoked by JAXB marshaller before and after the marshalling is done. My question is, so XmlAccessorType has nothing to do with the JAXB Binding and Unbinding from XML to java and java to XML, and it is all about Serialization.
Here the author mentions that with this annotation it gives control on serialization. In these methods, we can perform actions such as setting extra fields or modifying the value of existing fields. By setting XmlAccessorType, the bean can choose to only allow annotated fields to be serialized. We need to define two methods that will listen before and after the marshaller process in that class. We can customize the marshalling operation inside JAXB annotated class e.g.
Note that the POJO should be annotated with XmlRootElement annotation. tProperty("", Boolean.TRUE) Īll JAXB Providers are required to support the following set of properties. We can create an Unmarshaller instance using createUnmarshaller () method and then use the unmarshal () method to perform the unmarshalling. tProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE) These properties enable or disable the default behavior. We can further customize the behavior of marshaller by setting the properties. We can create an Unmarshaller instance using createUnmarshaller () method and then use the unmarshal () method to perform the unmarshalling. m.marshal( employeeObj, new PrintWriter( System.out ) ) Note: There is a new version for this artifact New Version 2.4.0-b180830. We can write the XML to the console, directly. JAXB provides an API and tools that automate the mapping between XML documents and Java objects. JaxbMarshaller.marshal( employeeObj, doc ) 1.5. Marshal to DOM Document DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance() ĭocumentBuilder db = dbf.newDocumentBuilder() jaxbMarshaller.marshal( employeeObj, new M圜ontentHandler() ) 1.4. The content handler can be used to customize the XML output during the marshalling process. Marshal to SAX ContentHandlerĪssume M圜ontentHandler is instance of. JaxbMarshaller.marshal( employeeObj, os ) 1.3. OutputStream os = new FileOutputStream( "employee.xml" )
#XMLACCESSORTYPE CODE#
The following code marshals the Employee object and writes the XML into employee.xml file.
This marshalling to XML can be done to a variety of output targets. Overloaded methods to marshal to different outputs The JAXB Marshaller interface is responsible for governing the process of serializing Java content trees i.e. Marshaller jaxbMarshaller = jaxbContext.createMarshaller() Įmployee employeeObj = new Employee(1, "Lokesh", "Gupta", new Department(101, "IT")) JAXBContext jaxbContext = JAXBContext.newInstance( Employee.class ) It can be used to convert an instance of Employee class into XML String. JAXBContext jaxbContext JAXBContext.newInstance( Employee.class ) Marshaller jaxbMarshaller jaxbContext.createMarshaller() Employee employeeObj new Employee(1, 'Lokesh', 'Gupta. In following example, we are creating a marshaller instance for the Employee class. In following example, we are creating a marshaller instance for the Employee class. Generally, to create a marshaller we can get the Marshaller instance from the JAXBContext. The JAXB Marshaller interface is responsible for governing the process of serializing Java content trees i.e.
