To convert a Java object to an XML format

The main Java classes used are: Javax.xml.bind.jaxbcontext,javax.xml.bind.marshaller (orchestration)

The code mainly shows as follows:

 Public classStudent {Private intID; PrivateString name; Private intAge ;  Public intgetId () {returnID; }     Public voidSetId (intID) { This. ID =ID; }     PublicString GetName () {returnname; }     Public voidsetName (String name) { This. Name =name; }     Public intGetage () {returnAge ; }     Public voidSetage (intAge ) {         This. Age =Age ; }     PublicStudent (intID, String name,intAge ) {        Super();  This. ID =ID;  This. Name =name;  This. Age =Age ; }     PublicStudent () {Super(); //TODO auto-generated Constructor stub    }}

Importjavax.xml.bind.annotation.XmlRootElement; @XmlRootElement Public classClassroom {Private intClassroomid; PrivateString Classroomname; PrivateStudent Student;  Public intGetclassroomid () {returnClassroomid; }     Public voidSetclassroomid (intClassroomid) {         This. Classroomid =Classroomid; }     PublicString Getclassroomname () {returnClassroomname; }     Public voidsetclassroomname (String classroomname) { This. Classroomname =Classroomname; }     PublicStudent getstudent () {returnstudent; }     Public voidsetstudent (Student Student) { This. Student =student; }     PublicClassroom (intClassroomid, String classroomname, Student Student) {        Super();  This. Classroomid =Classroomid;  This. Classroomname =Classroomname;  This. Student =student; }     PublicClassroom () {Super(); //TODO auto-generated Constructor stub    }}

Test:

ImportJavax.xml.bind.JAXBContext;ImportJavax.xml.bind.Marshaller; Public classTest {/**     * @paramargs*/     Public Static voidMain (string[] args)throwsexception{//TODO auto-generated Method StubJaxbcontext JBT= Jaxbcontext.newinstance (classroom.class); Classroom CR=NewClassroom (1, "one Shift",NewStudent (10, "Zhang San", 22)); Marshaller Ms=Jbt.createmarshaller ();                    Ms.marshal (CR, System.out); }}

Result: <?xml version= "1.0" encoding= "UTF-8" standalone= "yes"? ><classroom><classroomid>1</ Classroomid><classroomname> Class A </classRoomName><student><age>22</age><id> 10</id><name> Zhang San </name></student></classRoom>

The main areas of attention in this simple example are: 1. Code in the Test.java

2. Annotated @xmlrootelement in classroom class

To generate a Java object from the generated XML file:

Main code:

String xml = "<?xml version=\" 1.0\ "encoding=\" utf-8\ "standalone=\" yes\ "? ><classroom><classroomid >1</classRoomId><classRoomName> class </classRoomName><student><age>22</age> <id>10</id><name> Zhang San </name></student></classRoom> ";                 = Jaxbcontext.newinstance (classroom.  Class);                 = Unjbt.createunmarshaller ();                 = (classroom) Unms.unmarshal (new  StringReader (XML));                System.out.println (Uncr.getclassroomid ()+uncr.getclassroomname ());
