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. Then we'll focus on generating Java classes from XML schema and vice versa by using the JAXB-2 Maven plugin. First, we'll show how to convert Java objects to XML and vice versa. XmlAccessorType 16 import .XmlAttribute 17 import .XmlElement 18 import. In these methods, we can perform actions such as setting extra fields or modifying the value of existing fields. Overview This is an introductory tutorial on JAXB (Java Architecture for XML Binding). 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. agment – It determines whether or not document level events will be generated by the Marshaller.jaxb.noNamespaceSchemaLocation – It allows the client application to specify an xsi:noNamespaceSchemaLocation attribute in the generated XML data.jaxb.schemaLocation – It allows the client application to specify an xsi:schemaLocation attribute in the generated XML data.Whether or not the Marshaller will format the resulting XML data with line breaks and indentation. The Marshaller will use “ UTF-8” by default if this property is not specified. jaxb.encoding – The output encoding to use when marshalling the XML data.Some providers may support additional properties. tProperty("", Boolean.TRUE) Īll JAXB Providers are required to support the following set of properties. 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. m.marshal( employeeObj, new PrintWriter( System.out ) ) We can write the XML to the console, directly. 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. Searching the net indicates this package is no longer shipped with the java SE JDK. I am getting the message 'error: package does not exist'. Marshal to SAX ContentHandlerĪssume M圜ontentHandler is instance of . I am trying to build the jar files using ant on windows 10. This is useful when less than half of the fields/properties of a domain object are mapped. Now only explicitly mapped properties will be mapped. JaxbMarshaller.marshal( employeeObj, os ) 1.3. XmlAccessorType (XmlAccessType.NONE) By setting XmlAccessorType (XmlAccessType.NONE) we are disabling configuration by exception. OutputStream os = new FileOutputStream( "employee.xml" ) The following code marshals the Employee object and writes the XML into employee.xml file. Overloaded methods to marshal to different outputs 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. 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. This marshalling to XML can be done to a variety of output targets. The JAXB Marshaller interface is responsible for governing the process of serializing Java content trees i.e.
