Mapping between XML in Java and entity classes

Entity class:

1  PackageXML;2 3 Importjavax.xml.bind.annotation.XmlRootElement;4 5 @XmlRootElement6  Public classUser {7 String name;8 String English_name;9 String age;Ten String sex; One String address; A String description; -      PublicUser () {} -      the      PublicUser (string name, String english_name, String age, String sex , - string address, string description) { -          This. name=name; -          This. english_name=English_name; +          This. age=Age ; -          This. sex=sex; +          This. address=address; A          This. description=description; at     } -      PublicString GetName () { -         returnname; -     } -      Public voidsetName (String name) { -          This.

I. Translating Java objects into XML files

1  PackageXML;2 3 ImportJava.io.File;4 5 ImportJavax.xml.bind.JAXBContext;6 Importjavax.xml.bind.JAXBException;7 ImportJavax.xml.bind.Marshaller;8 9 /**Ten * Mapping classes to XML One  * @authorAdministrator A  * -  */ -  Public classDemo1 { the      Public Static voidMain (string[] args) { -         //create an XML object and save it in the specified location -File File =NewFile ("D:\\javaitem\\xml\\src\\xml\\1.xml"); -         //declare a Jaxbcontext object + Jaxbcontext Jaxbcontext; -         Try { +             //Specifies the mapped class, creating the context of the Jaxbcontext object AJaxbcontext = Jaxbcontext.newinstance (User.class); at             //Create a Conversion object Marshaller -Marshaller m =Jaxbcontext.createmarshaller (); -             //to create data in an XML file -User User =NewUser ("Zhang San", "Zhangsnan", "30", "Male", "Hefei, Anhui", "software Engineer")); -             //to convert a user object in a Java class to XML - m.marshal (user, file); inSYSTEM.OUT.PRINTLN ("Conversion complete"); -}Catch(jaxbexception e) { to e.printstacktrace (); +         } -     } the}

Two. converting XML files to Java objects

1  PackageXML;2 3 ImportJava.io.File;4 5 ImportJavax.xml.bind.JAXBContext;6 Importjavax.xml.bind.JAXBException;7 ImportJavax.xml.bind.Unmarshaller;8 9 Ten  One  Public classDemo2 { A      Public Static voidMain (string[] args) { -File file=NewFile ("D:\\javaitem\\xml\\src\\xml\\1.xml"); - Jaxbcontext Jaxbcontext; the         Try { -Jaxbcontext=jaxbcontext.newinstance (User.class); -Unmarshaller u=Jaxbcontext.createunmarshaller (); -User user=(User) u.unmarshal (file); +System.out.println ("Name:" +user.getname ()); -System.out.println ("English name:" +user.getenglish_name ()); +System.out.println ("Age:" +user.getage ()); ASystem.out.println ("Gender:" +user.getsex ()); atSYSTEM.OUT.PRINTLN ("Address:" +user.getaddress ()); -System.out.println ("Description:" +user.getdescription ()); -}Catch(jaxbexception e) { - e.printstacktrace (); -         } -     } in}
