我们目前遇到了JAX-WS实现的问题,尤其是获取服务返回的值,在我们的例子中,它总是为null,尽管我们给它一个值。
在对我们的问题进行更多解释之前的一些代码:
这是我们行动的签名:
@WebMethod(action = "urn:genererEdition")
public void genererEdition(
@WebParam(name = "requeteEdition", targetNamespace = "http://creditcgi.com/serviceeditique", partName = "requete")
RequeteEdition requete,
@WebParam(name = "reponseEdition", targetNamespace = "http://creditcgi.com/serviceeditique", mode = WebParam.Mode.OUT, partName = "reponse")
Holder<ReponseEdition> reponse,
@WebParam(name = "documentProduit", targetNamespace = "", mode = WebParam.Mode.OUT, partName = "documentProduit")
Holder<byte[]> documentProduit);
以下是我们的网络服务测试用例:
@Test
public void testCallGenererEdition() {
RequeteEdition requete = new RequeteEdition();
Holder<ReponseEdition> reponseHolder = new Holder<ReponseEdition>(new ReponseEdition());
Holder<byte[]> documentHolder = new Holder<byte[]>(new byte[512]);
editique.genererEdition(requete, reponseHolder, documentHolder);
Assert.assertNotNull(reponseHolder.value);
Assert.assertNotNull(reponseHolder.value.getCodeRetour());
}
最后,我们的WS实现:
@Override
public void genererEdition(RequeteEdition requete,
Holder<ReponseEdition> reponse, Holder<byte[]> documentProduit) {
// if we do no instanciate ReponseEdition, we got a Null Pointer Exception
reponse.value = new ReponseEdition();
reponse.value.setCodeRetour("OK");
}
正如您在测试中看到的那样,我们总是变为空。在响应持有者中总是返回一个空对象我们做错了什么?
提前谢谢。

它将解决您在响应中获取NULL值的问题。
....genererEdition(....){
ReponseEdition re = new ReponseEdition();
reponse.value = re;
}
