MessageContext和传输头之续二（实例演示：客户端中访问消息上下文）
我们还是以HelloWord为例，为更简单点，我们删除了一些Handler，只留了一些基本功能。
服务端

同学们,你们好
HelloWordClient程序通过对port所引用对象获得了访问HTTP请求头信息的能力。这里首先将port引用的对象转型为BindingProvider，这样可以通过BindingProvider所提供的getRequestContext方法获得当前上下文对象的引用。getRequestContext方法返回一个Map引用。
客户端还创建了一个名为my_header的空的Map对象，该对象可接收的键/值类型为：String/Object。其中对象类型为一个由工具类Collections的singletonList方法产生的List<String>对象。通过my_header将额外的键/值对插入HTTP请求头中。尽管针对服务操作sayHello只调用一次，但是自这以后的每次调用产生的HTTP请求均包括加入的头信息。
在HelloWordClient程序的末尾处，又一次将port引用的对象实例转型为BindingProvider，然后调用getResponseContext方法获得HTTP请求响应的上下文对象，该对象同样也是一个Map类型。
