1. Define JavaBean. Note @XmlRootElement annotations that map JavaBean to XML elements.

 PackageCom.huey.demo.bean;Importjavax.xml.bind.annotation.XmlRootElement;ImportLombok. Allargsconstructor;ImportLombok. Data;ImportLombok. Noargsconstructor, @Data @noargsconstructor@allargsconstructor@xmlrootelement Public classBook {PrivateString title; PrivateString author; PrivateString Publisher; PrivateString ISBN;}

 Package Com.huey.demo.bean; Import javax.xml.bind.annotation.XmlRootElement; Import Lombok. Allargsconstructor; Import Lombok. Data; Import Lombok. Noargsconstructor, @Data @noargsconstructor@allargsconstructor@xmlrootelementPublicclass  resultmsg {    private  String resultcode;     Private String message;    

2. Define the service interface. Note the role of the individual annotations.

 Packagecom.huey.demo.ws;Importjava.util.List;ImportJavax.jws.WebService;ImportJavax.ws.rs.DELETE;ImportJavax.ws.rs.GET;ImportJavax.ws.rs.POST;ImportJavax.ws.rs.PUT;ImportJavax.ws.rs.Path;ImportJavax.ws.rs.PathParam;Importjavax.ws.rs.Produces;ImportJavax.ws.rs.core.MediaType;ImportCom.huey.demo.bean.Book;Importcom.huey.demo.bean.ResultMsg; @WebService Public InterfaceBookservice {@GET//Specify the request method@Path ("/BOOK/{ISBN}")//Specifies the URI of the resource@Produces ({mediatype.application_xml})//Specify the media type for request/response     PublicBook GetBook (@PathParam ("ISBN") String ISBN); @GET @Path ("/books") @Produces ({mediatype.application_xml}) PublicList<book>Getbooks (); @POST @Path ("/book") @Produces ({mediatype.application_xml}) Publicresultmsg addbook (book book); @PUT @Path ("/BOOK/{ISBN}") @Produces ({mediatype.application_xml}) PublicResultmsg Updatebook (@PathParam ("ISBN") String ISBN, Book book); @DELETE @Path ("/BOOK/{ISBN}") @Produces ({mediatype.application_xml}) PublicResultmsg Deletebook (@PathParam ("ISBN") String ISBN);}

3. Implement the Service interface.

 PackageCom.huey.demo.ws.impl;Importjava.util.ArrayList;Importjava.util.List;ImportJavax.jws.WebService;Importorg.apache.commons.lang.StringUtils;ImportCom.huey.demo.bean.Book;ImportCOM.HUEY.DEMO.BEAN.RESULTMSG;ImportCom.huey.demo.ws.BookService;Importcom.sun.org.apache.commons.beanutils.BeanUtils; @WebService Public classBookserviceimplImplementsBookservice {List<Book> books =NewArraylist<book>();  PublicBookserviceimpl () {Books.add (NewBook ("The dedication of the suspect X", "The east of the GUI Wu", "Nanhai Publishing Company", "9787544245555")); Books.add (NewBook ("Kite-chasing", "Husseini", "Shanghai People's publishing house", "9787208061644")); Books.add (NewBook ("See", "Chai Jing", "Guangxi Normal University Press", "9787549529322")); Books.add (NewBook ("White Nights", "Dong Ye gui wu", "Nanhai Publishing Company", "9787544242516")); }             PublicBook GetBook (String ISBN) { for(book book:books) {if(BOOK.GETISBN (). Equals (ISBN)) {returnBook ; }        }        return NULL; }         PublicList<book>Getbooks () {returnBooks; }         Publicresultmsg addbook (book book) {if(Book = =NULL||Stringutils.isempty (BOOK.GETISBN ())) {            return NewResultmsg ("Fail", "parameter is incorrect!") "); }        if(GetBook (BOOK.GETISBN ())! =NULL) {            return NewResultmsg ("FAIL", "the book already exists!") ");        } books.add (book); return NewResultmsg ("SUCCESS", "Add success!") "); }     Publicresultmsg Updatebook (String ISBN, Book book) {Book Target=GetBook (ISBN); if(Target! =NULL) {resultmsg resultmsg=NewResultmsg ("SUCCESS", "Update success!") "); Try{beanutils.copyproperties (target, book); } Catch(Exception e) {resultmsg=NewResultmsg ("FAIL", "Unknown Error!") "); }            returnresultmsg; }        return NewResultmsg ("Fail", "the book does not exist!") "); }         Publicresultmsg Deletebook (String ISBN) { Book Book=GetBook (ISBN); if(Book! =NULL) {books.remove (book); return NewResultmsg ("SUCCESS", "Delete succeeded!") "); }        return NewResultmsg ("Fail", "the book does not exist!") "); }}

4. Spring configuration.

5. Web. XML configuration.
