使用JAX-WS修改Web服务的响应 [英] Modify response of web service with JAX-WS

问题描述

如何像这样修改响应的名称空间:

旧回复:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <ns2:GetAmountResponse xmlns:ns2="http://ws.dsi.otn.com/dab">
         <etat>0</etat>
         <montant>500.0</montant>
      </ns2:GetAmountResponse>
   </soap:Body>
</soap:Envelope>

想要新的回复:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <GetAmountResponse xmlns="http://ws.dsi.otn.com/dab">
         <etat>0</etat>
         <montant>500.0</montant>
      </GetAmountResponse>
   </soap:Body>
</soap:Envelope>

我要删除ns2名称pce前缀.

解决方案

在第一种情况下，GetAmountResponse在命名空间http://ws.dsi.otn.com/dab中，而etat和montant在默认(空)命名空间中. /p>

在所需的新消息中，GetAmountResponse，etat和montant都在命名空间http://ws.dsi.otn.com/dab中.

可以从您的类的名称空间控制名称空间.在所有名称空间中使用相同的名称空间，您将在相同的名称空间中使用它们，将类保留为默认值，并且它们默认为空名称空间.

例如，如果您要在Web服务类中添加以下内容:

@WebMethod
    public 
    @WebResult(name = "getAmountResponse", targetNamespace = "http://ws.dsi.otn.com/dab")
    AmountResponse getAmount(
            @WebParam(name = "getAmountRequest", targetNamespace = "http://ws.dsi.otn.com/dab") AmountRequest request) {

        AmountResponse response = new AmountResponse();
        response.setEtat(0);
        response.setMontant(500.0);

        return response;
    }

具有这样的响应类:

@XmlRootElement
public class AmountResponse {
    private int etat;
    private double montant;
    // getter and setters omitted
}

您将获得第一种肥皂消息.

但是，如果您将响应类更改为如下所示:

@XmlRootElement(namespace = "http://ws.dsi.otn.com/dab")
@XmlAccessorType(XmlAccessType.NONE)
public class AmountResponse {

    @XmlElement(namespace = "http://ws.dsi.otn.com/dab")
    private int etat;

    @XmlElement(namespace = "http://ws.dsi.otn.com/dab")
    private double montant;

    // getters and setter omitted
}

您将把所有标签都放在同一个命名空间中，并且得到的内容等同于所需的新型消息.我说的是对等的，因为我认为您不会完全这样:

<GetAmountResponse xmlns="http://ws.dsi.otn.com/dab">
     <etat>0</etat>
     <montant>500.0</montant>
</GetAmountResponse>

相反，更有可能得到这样的东西:

<ns2:getAmountResponse xmlns:ns2="http://ws.dsi.otn.com/dab">
     <ns2:etat>0</ns2:etat>
     <ns2:montant>500.0</ns2:montant>
</ns2:getAmountResponse>

这两个消息看起来并不相同，但它们具有相同的"XML含义".

如果您绝对希望它看起来像这样，我认为您将必须低级"并使用

new response wanted :

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <GetAmountResponse xmlns="http://ws.dsi.otn.com/dab">
         <etat>0</etat>
         <montant>500.0</montant>
      </GetAmountResponse>
   </soap:Body>
</soap:Envelope>

I want to remove the ns2 namespce prefix.

解决方案

In the first case, the GetAmountResponse is in namespace http://ws.dsi.otn.com/dab while etat and montant are in a default (empty) namespace.

In the new message you want, GetAmountResponse, etat and montant are all in namespace http://ws.dsi.otn.com/dab.

The namespaces can be controlled from the namespaces of your classes. Use the same namespace in all and you will have them in the same namespace, leave classes with defaults and they default to empty namespace.

For example, if you were to have something like this in your web service class:

@WebMethod
    public 
    @WebResult(name = "getAmountResponse", targetNamespace = "http://ws.dsi.otn.com/dab")
    AmountResponse getAmount(
            @WebParam(name = "getAmountRequest", targetNamespace = "http://ws.dsi.otn.com/dab") AmountRequest request) {

        AmountResponse response = new AmountResponse();
        response.setEtat(0);
        response.setMontant(500.0);

        return response;
    }

with a response class like this:

@XmlRootElement
public class AmountResponse {
    private int etat;
    private double montant;
    // getter and setters omitted
}

you will end up with the first type of soap message.

But if you change the response class to look like this instead:

@XmlRootElement(namespace = "http://ws.dsi.otn.com/dab")
@XmlAccessorType(XmlAccessType.NONE)
public class AmountResponse {

    @XmlElement(namespace = "http://ws.dsi.otn.com/dab")
    private int etat;

    @XmlElement(namespace = "http://ws.dsi.otn.com/dab")
    private double montant;

    // getters and setter omitted
}

you will bring all tags in the same namespace and you get something equivalent to the new type of message you want. I said equivalent because I don't think you will get exactly this:

<GetAmountResponse xmlns="http://ws.dsi.otn.com/dab">
     <etat>0</etat>
     <montant>500.0</montant>
</GetAmountResponse>

It's more likely to get something like this instead:

<ns2:getAmountResponse xmlns:ns2="http://ws.dsi.otn.com/dab">
     <ns2:etat>0</ns2:etat>
     <ns2:montant>500.0</ns2:montant>
</ns2:getAmountResponse>

It's the same "XML meaning" for both messages although they don't look the same.

If you absolutely want it to look like that, I think you will have to go "low level" and use something like a SOAP handler to intercept the response and modify it. But be aware that it won't be a trivial task to change the message before it goes on the wire.
