Web Service Learning Vi: CXF resolving data types that cannot be processed

CXF is not able to handle data types such as map complexity and requires a separate conversion process.

General Idea: Create a converter and a corresponding type of data structure that can be processed, converting types that cannot be processed into types that can be processed:

Steps:

first, Create an example of a type that can be handled: to convert map<string,user>

 packagews;Importjava.util.List; public classStringuser { public Static classEntry {PrivateString key; PrivateUser value;  publicString GetKey () {returnkey; }         public voidSetkey (String Key) { this. Key =key; }         publicUser getValue () {returnvalue; }         public voidsetValue (User Value) { this. Value =value; }    }    PrivateList<entry>values;  publicList<entry>getValues () {returnvalues; }     public voidSetvalues (list<entry>values) {         this. Values =values; }        }

second, to create a converter, you need to inherit the abstract class xmladapter<valuetype,boundtype>, where ValueType is a type that can be handled boundtype is a type that cannot be processed

 packagews;Importjava.util.ArrayList;Importjava.util.HashMap;Importjava.util.List;Importjava.util.Map;Importjavax.xml.bind.annotation.adapters.XmlAdapter;ImportWs. stringuser.entry;/*** The converter is responsible for converting stringuser with map<string, user> * where the first parameter stringuser is the type that the CXF can handle * The second parameter map<string, user> is CXF Types that cannot be processed*/ public classFkxmladapterextendsxmladapter<stringuser, map<string, user>> {    /*** Convert Stringuser into map<string, user>*/@Override publicmap<string, user> unmarshal (stringuser v)throwsException {Map<string, user> map =Newhashmap<string, user>();  for(Entry u:v.getvalues ()) {map.put (u.getkey (), u.getvalue ()); }        returnmap; }    /*** Convert map<string, user> into Stringuser*/@Override publicStringuser Marshal (map<string, User> V)throwsException {stringuser u=NewStringuser (); List<Entry> list =NewArraylist<entry>();  for(String key:v.keyset ()) {Entry e=NewEntry ();            E.setkey (key);            E.setvalue (v.get (key));        List.add (e);        } u.setvalues (list); returnu; }}

third, the method defined in the Web service needs to use the annotation @XmlJavaTypeAdapter (value=fkxmladapter.class) to indicate the processing converter corresponding to the return value

@WebMethod (operationname= "getsecusers") @WebResult (name= "returninfo")public@ Xmljavatypeadapter (value=fkxmladapter.class) map<string, user> getsecusers ();

Iv. test the following to view the WSDL document return data types are resolvable types

Service-side Implementation Class:

 packagews.impl;Importjava.util.ArrayList;Importjava.util.Date;Importjava.util.HashMap;Importjava.util.List;Importjava.util.Map;Importjavax.jws.WebService;ImportWs. hellowordi;ImportWs. User;/*** Class Description *@authorWangjunyu * @createDate 2016-7-10 a.m. 10:59:27 *@versionV1.0*/@WebService (endpointinterface= "ws." Hellowordi ", servicename=" Hellowordimpl ") public classHellowordimplImplementsHellowordi { publicstring Sayhi (string Name) {returnname+ "hello, The current time is:" +NewDate (); }     publicList<user>getusers (user user) {System.out.println ("test:" +User.getname ()); List<User> list =NewArraylist<user>(); User U1=NewUser (); U1.setid ("1"); U1.setname ("xiao ming");        List.add (u1); User U2=NewUser (); U2.setid ("2"); U2.setname ("snow plum");        List.add (u2); returnlist; } @Override publicmap<string, user>getsecusers () {Map<String,User> map =NewHashmap<string,user>(); User U1=NewUser (); U1.setid ("1"); U1.setname ("xiao ming"); Map.put (A, u1); User U2=NewUser (); U2.setid ("2"); U2.setname ("little red"); Map.put (Two, u2); returnmap; }    }

 package ws; Import javax.xml.ws.Endpoint; Import ws.impl.HelloWordImpl;  public class servermain {    publicstaticvoid  main (string[] Args)     {                 New  Hellowordimpl ();        Endpoint.publish ("http://192.168.0.104/test", hw);        SYSTEM.OUT.PRINTLN ("WebService exposed successfully! ");    }}

Client Print:

 packagews;Importjava.util.List;Importws.impl.HelloWordImpl; public classClientmain {/**     * @paramargs*/     public Static voidmain (string[] Args) {stringuser u=hw.getsecusers (); System.out.println (u.getvalues (). Get (0). getValue (). getName ()); System.out.println (u.getvalues (). Get (1). getValue (). getName ()); }}
