问题描述

我是Java新手，并且认为在我已经熟悉的.NET WCF服务之上实现客户端应用程序是一个很好的学习练习。

I new to Java, and thought it'd be a nice learning exercise to implement a client application on top of a .NET WCF service I'm already familiar with.

我从最新的JAX-WS运行wsimport.bat（ https://jax-ws.java.net / ）生成客户端代理，但我坚持使用身份验证部分。 WCF服务使用应用程序级别用户名/密码进行身份验证。我不知道在哪里提供凭据。

I ran wsimport.bat from the latest JAX-WS (https://jax-ws.java.net/) to generate the client proxies, However I'm stuck with the authentication part. The WCF service uses Application level Username/Password to authenticate. I don't know where to supply the credentials.

在C＃中，对于这个WCF服务，我只需要添加一个服务引用，并执行以下操作：

In C#, for this WCF Service I just need to add a service reference, and do the following:

var client = new ServiceClient();
client.ClientCredentials.UserName.UserName = "username";
client.ClientCredentials.UserName.Password = "password";
client.DoSomething();

来自Fiddler，调用client.DoSomething（）会产生以下请求：

From Fiddler, calling client.DoSomething() produces the following request:

<?xml version="1.0"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
  <s:Header>
    <o:Security xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" s:mustUnderstand="1">
      <u:Timestamp u:Id="_0">
        <u:Created>2013-05-20T01:34:28.353Z</u:Created>
        <u:Expires>2013-05-20T01:39:28.353Z</u:Expires>
      </u:Timestamp>
      <o:UsernameToken u:Id="uuid-da5b7b57-dbb4-4c54-b529-f5b41fc728b4-1">
        <o:Username>username</o:Username>
        <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">password</o:Password>
      </o:UsernameToken>
    </o:Security>
  </s:Header>
  <s:Body>
    <DoSomething xmlns="http://tempuri.org/"/>
  </s:Body>
</s:Envelope>

这是我目前正在使用的Java：

Here is the Java I'm currently using:

SomeService service = new SomeService();
ISomeService port = service.getBasicHttpBindingISomeService();
DoSomethingResponse response = port.getDoSomething();

这会产生以下请求：

<?xml version="1.0"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
  <S:Body>
    <ns6:DoSomething xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays" xmlns:ns6="http://tempuri.org/" xmlns:ns7="http://schemas.microsoft.com/2003/10/Serialization/"/>
  </S:Body>
</S:Envelope>

它缺少安全节点，所以我不知道如何在Java端设置它。我错过了什么？

It's missing the Security node, so I'm not sure how to set that up on the Java side. What am I missing?

如果有更好的替代方案可以满足我的需求，我不会百分之百地使用JAX-WS。但是，无法修改WCF服务以重新配置，因为它无法实现。

I'm not 100% bound to using JAX-WS, if there is a better alternative out there for my needs. However, the WCF service can not be modified to reconfigured, as it's out of my reach.

推荐答案

您需要从Java客户端创建自定义CallbackHandler。我不是Java方面的专家，但我知道我的一些客户使用Metro库与我的WCF Web服务进行通信。

You need to create a custom CallbackHandler from your Java client. I am not an expert in Java but I know that some of my clients use Metro libraries to communicate with my WCF web services.

尝试搜索创建带/不带的CallbackHandler地铁图书馆。

Try searching for creating a CallbackHandler with/without Metro library.

您可以从下载地铁图书馆这里。

一个例子我的建议。
