Another option for debugging is to set a breakpoint on the XSL transformation primitive in the Mediation Flow Editor.
另一个调试选项是在MediationFlowEditor中对XSL转换原语设置断点。
We'll introduce another mediation primitive in the request flow that sets the desired endpoint address in the transient context.
我们将在请求流中引入另一个中介元素，该中介元素在瞬态上下文中设置了所需的端点地址。
When you create a Service invoke primitive in the flow, the tool asks you to specify the partner reference and operation that should be invoked.
当创建流内的一个ServiceInvoke原语时，此工具会要求您指定应被调用的partner引用和操作。
If you are familiar with relational databases such as IBM DB2, MySQL, or PostgreSQL, then you will find key-value stores primitive in comparison.
如果您熟悉关系数据库，例如IBMDB 2、MySQL或PostgreSQL，则相比之下您将发现键值存储非常简单。
To understand how an XSL Transformation primitive in a mediation flow is executed at runtime, consider the following scenario shown in Figure 14.
要理解中介流中的XSLTransformation原语如何在运行时执行，考虑如图14所示的场景。
In this article, we'll walk through a simple mediation scenario that features a message logger mediation primitive in both request and response flows.
在本文中，我们将演练一个简单的中介场景，其中重点突出请求和响应流中的Message Logger中介原语。
Fine-grained trace in the Integration Test Client will allow you to see the inputs and outputs to each XSL Transformation primitive in the mediation flow.
IntegrationTestClient中的细粒度的跟踪将允许您查看中介流中每个XSLTransformation原语的输入和输出。
This value is important, as it will enable us to build an http request, allowing the XSLTransform primitive in the mediation flow to load it dynamically.
这个值很重要，因为有了它就可以构建http请求，使中介流中的 XSLTransform原语可以动态地装载它。
There is only one mediation primitive in the request flow, namely the Message Logger primitive, which logs every message that flows through the bus to a database.
在请求流程中，仅有一个中介基元，即MessageLogger 基元，它记录经总线到数据库的每条消息。
More interestingly, these properties can gain their values from a registry by using a policy lookup primitive, which is the purpose of the RetrievePolicy primitive in Figure 10.
更加有趣的是，通过使用一个策略查找原语，这些属性可以从注册表中获得它们的值，这正是图10所示的RetrievePolicy原语的目的。
Therefore, you can only aggregate in a particular flow: a Fan in mediation primitive in a response flow can't be used to aggregate messages from a Fan Out mediation primitive in a request flow.
因此，您可以仅在特定流中聚合：响应流中的扇入中介不能用于聚合来自请求流中的扇出中介原语的消息。
Therefore, you can only aggregate in a particular flow: a Fan in mediation primitive in a response flow can't be used to aggregate messages from a Fan Out mediation primitive in a request flow.
因此，您可以仅在特定流中聚合：响应流中的扇入中介不能用于聚合来自请求流中的扇出中介原语的消息。
