我正在尝试测试一个使用基本身份验证保护的Spring Web服务。为了进行这些测试，我编写了一个Web服务客户端，使用了Spring的WebServiceTemplate类。
当我将模板的MessageSender创建为一个org.springframework.ws.transport.http.CommonsHttpMessageSender对象bean，并使用org.apache.commons.httpclient.UsernamePasswordCredentials时，我的Web服务客户端调用到Web服务是可以正常工作的，尽管客户端可以工作，但代码有一个警告，指出CommonsHttpMessageSender类现在已经被弃用，我应该使用HttpComponentsMessageSender替代。
我尝试重新配置客户端的WebServiceTemplate以使用更新的HttpComponentsMessageSender类，但我无法正确配置基本认证部分。对于新的HttpComponentsMessageSender类，我使用org.apache.http.auth.UsernamePasswordCredentials类创建凭据，但是当我调用Web服务时，凭据似乎无法随请求一起使用？是否有任何使用这些新类进行身份验证请求的WebServiceTemplate客户端的工作示例呢？
我的旧代码与已弃用的类一起使用的jar文件：commons-httpclient-3.1，spring-ws-core-2.2.0.RELEASE。
我的新代码与较新的类一起使用的jar文件：httpclient-4.3.4，httpcore-4.3.2，spring-ws-core-2.2.0.RELEASE。
目前，我的非工作代码测试配置如下：

Object response = webServiceTemplate.marshalSendAndReceive(request);其中请求只是Web服务的有效负载POJO。 - Going BananasHttpClient类来设置一个带有添加了AuthCache的HttpClientContext，并在调用服务时使用它。是否有示例展示如何为Spring的WebServiceTemplate设置AuthCache？ - Going BananasHttpClient，而是在HttpComponentsMessageSender上设置了凭据，它会处理其余的事情。你可能想要看一下HttpComponentsMessageSender的源代码。 - M.
