JAX-WS: exemple d’outil wsgen

L’outil wsgen est utilisé pour analyser une classe d’implémentation de service Web existante et génère les fichiers requis (artefacts portables JAX-WS) pour le déploiement de services Web. Cet outil wsgen est disponible dans le dossier` $ JDK/bin`.

Cas d’utilisation

2 cas d’utilisation courants pour l’outil wsgen:

  1. Génère des artefacts portables JAX-WS (fichiers Java) pour le service Web

déploiement.

  1. Génère des fichiers WSDL et xsd, à des fins de test ou de client de service Web

développement.

Voyons une classe d’implémentation de service Web, assez simple, juste une méthode pour renvoyer une chaîne.

File: ServerInfo.java

package com.mkyong.ws;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public class ServerInfo{

    @WebMethod
    public String getIpAddress() {

        return "10.10.10.10";

    }

}

1. Génère des artefacts portables JAX-WS (fichiers Java)

Pour générer tous les artefacts portables JAX-WS pour la classe d’implémentation de service Web ci-dessus ( ServerInfo.java ), utilisez la commande suivante:

Commande: wsgen usage

D:\>wsgen -verbose -keep -cp . com.mkyong.ws.ServerInfo

Note:   ap round: 1[ProcessedMethods Class: com.mkyong.ws.ServerInfo][should process method: getIpAddress hasWebMethods: true][endpointReferencesInterface: false][declaring class has WebSevice: true][returning: true][WrapperGen - method: getIpAddress()][method.getDeclaringType(): com.mkyong.ws.ServerInfo][requestWrapper: com.mkyong.ws.jaxws.GetIpAddress][ProcessedMethods Class: java.lang.Object]com\mkyong\ws\jaxws\GetIpAddress.java
com\mkyong\ws\jaxws\GetIpAddressResponse.java
Note:   ap round: 2

Dans ce cas, il a généré quatre fichiers:

  1. com \ mkyong \ ws \ jaxws \ GetIpAddress.java

  2. com \ mkyong \ ws \ jaxws \ GetIpAddress.class

  3. com \ mkyong \ ws \ jaxws \ GetIpAddressResponse.java

  4. com \ mkyong \ ws \ jaxws \ GetIpAddressResponse.class

File: GetIpAddress.java

package com.mkyong.ws.jaxws;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;

@XmlRootElement(name = "getIpAddress", namespace = "http://ws.mkyong.com/")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "getIpAddress", namespace = "http://ws.mkyong.com/")
public class GetIpAddress {

}

File: GetIpAddressResponse.java

package com.mkyong.ws.jaxws;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;

@XmlRootElement(name = "getIpAddressResponse", namespace = "http://ws.mkyong.com/")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "getIpAddressResponse", namespace = "http://ws.mkyong.com/")
public class GetIpAddressResponse {

    @XmlElement(name = "return", namespace = "")
    private String __return;

   /** **
     **
     **  @return
     **      returns String
     ** /    public String getReturn() {
        return this.__return;
    }

   /** **
     **
     **  @param __return
     **      the value for the __return property
     ** /    public void setReturn(String __return) {
        this.__return = __return;
    }

}

2. Génère WSDL et xsd

Pour générer des fichiers WSDL et xsd pour la classe d’implémentation de service Web ci-dessus ( ServerInfo.java ), ajoutez un -wsdl supplémentaire dans la commande` wsgen`:

Commande: wsgen usage

D:\>wsgen -verbose -keep -cp . com.mkyong.ws.ServerInfo -wsdl

Note:   ap round: 1[ProcessedMethods Class: com.mkyong.ws.ServerInfo][should process method: getIpAddress hasWebMethods: true][endpointReferencesInterface: false][declaring class has WebSevice: true][returning: true][WrapperGen - method: getIpAddress()][method.getDeclaringType(): com.mkyong.ws.ServerInfo][requestWrapper: com.mkyong.ws.jaxws.GetIpAddress][ProcessedMethods Class: java.lang.Object]com\mkyong\ws\jaxws\GetIpAddress.java
com\mkyong\ws\jaxws\GetIpAddressResponse.java
Note:   ap round: 2

Dans ce cas, il a généré six fichiers:

  1. com \ mkyong \ ws \ jaxws \ GetIpAddress.java

  2. com \ mkyong \ ws \ jaxws \ GetIpAddress.class

  3. com \ mkyong \ ws \ jaxws \ GetIpAddressResponse.java

  4. com \ mkyong \ ws \ jaxws \ GetIpAddressResponse.class

  5. ServerInfoService__schema1.xsd

  6. ServerInfoService.wsdl
