If at any point in the code, an error occurs such that processing cannot continue, we retrieve the system error message (if any), and display it along with our own message.

The flow overrides the dummy map at runtime based on the country code in the incoming message.
该流在运行时根据收到消息中的国家代码重写虚拟映射。
The fact that the API remains common across message types encourages code reuse even in environments where the message types are completely different.
此api可以对多种消息类型进行公共访问这一事实可促进代码重用，即使在消息类型完全不同的环境中也是如此。
Hence, even though the exact representation of a message is different in the two technologies, the code required to access the message content is similar.
因此，尽管消息的准确表示形式在两种技术中不同，但是访问消息内容所需的代码类似。

这个质询消息包含让发送者答复的指示，以便将其加到“白名单”中(这个响应消息必须包含由“白名单”过滤器生成的代码)。
Since there is no clear definition of the message in WSDL, the web services tooling cannot generate this code, which can make such a solution more error prone.
由于WSDL中并没有消息的确切定义，因此Web服务工具不能生成此代码，而这将导致此类解决方案更容易出错。
