映射消息实例通过会话对象创建。
JMS提供者必须支持嵌入的映射消息来对集合类进行转换。
The JMS provider must support nested map messages to convert collection classes.
映射消息实际上是一组键值对，这使它适合携带扁平结构的文档，如前文所述。
The map message is essentially a set of key-value pairs, which makes it suitable to carry a flattened document, as described in the previous section.
例如，如果有JMS映射消息发送到导出，则不能使用默认绑定，因为不知道此映射的格式。
For example, if a JMS map message is sent to an export, we cannot use default bindings because we don't know what this map looks like.
这种情况下，您可以使用一个映射来将消息从一种结构转换为另一种结构。
In this case, you can use a mapping to convert the message from one structure to another.
在这种情况下，可以使用映射将消息从一个结构转换为另一个结构。
In this case a mapping can be used to convert the message from one structure to another.
映射节点为输入消息或数据库中的字段之间、以及到一个或多个输出消息或数据库表执行映射提供了图形方法。
The Mapping node provides a graphical way of performing mappings between fields in an input message or database, to one or more output messages or database tables.
因此，您需要告诉系统要将哪种类型的消息映射到服务上的哪个操作。
Hence, you need to tell the system which type of message to map to which operation on the service.
消息和数据转换在映射中执行。
因此，有了文字使用，在WSDL中从抽象消息映射到连接上具体的请求和响应是完全明确的。
Thus the mapping from the abstract messages in the WSDL to the concrete requests and responses on the wire is completely unambigous with literal usage.
将显示关于缺少映射文件的错误消息。
可以引入输入JS p页来通过请求中的存储属性传递消息映射，从而完成此工作。
You can achieve this by introducing an input JSP page to pass the message map via a stored attribute in the request.
属性映射在消息选择已经在一个路由中发生之后才被应用。
Property Maps are applied after message selection has already occurred within a route.
可以使用属性别名将消息参数映射到相关属性。
You can map a message parameter to a correlation property using a property alias.
另外，服务实现者有时候也可能希望开发自己的方式映射传入的SOAP消息。
Also, sometimes a service implementer might want to develop his or her own way of mapping an incoming SOAP message.
本技巧描述了如何使用这些JAX-RPC映射来发送SOAP消息中的附件。
This tip describes how to use those JAX-RPC mappings to send attachments in SOAP messages.
图6显示了请求消息的这种映射的视图。
Figure 6 shows a view of this mapping to the request message.
然后将映射的消息返回到消息流，处理工作将在流中的下一个步骤(节点)处继续。
The mapped message is then returned to the message flow, and processing continues with the next step (node) in the flow.
尽管源消息的许多字段可以直接映射到目标消息中的字段，但是有些字段需要更复杂的操作。
Although many of the fields from the source message directly map into fields in the target message, a few of them require more complex manipulation.
将输入消息的所有部分都映射到输出消息的相应部分中，然后保存转换器服务。
Map all parts from the input message to the corresponding part of the output message and save the transformer service.
清单2给出这个映射产生的XML输出消息。
Listing 2 shows the XML output message that is produced by the map.
当为该消息流构建BAR文件时，所有映射都包含在消息流中，因此，任何一个映射中的任何改变都需重新部署所有代码。
When the BAR file is built for this message flow, all maps are included in the message flow, and therefore any change to one map requires redeployment of all of the code.
任何响应或错误消息将被映射到返回消息中的状态字段。
Any response or fault message is mapped out to the status field in the return message.
此编辑器与之前版本一样会显示输入和目标消息映射。
The editor is similar to the previous version in that it shows the input and target message mappings.
如果仅将错误定义为一个元素，则从消息名称映射异常的名称，从消息的命名空间映射数据包(请参见清单5)。
If the fault is defined simply as an element, then the name of the exception is mapped from the message name, and the package is mapped from the message's namespace (see Listing 5).
消息映射属性将消息内容表示为映射。
The message map attribute represents the message content as a map.
要开始开发映射，请将映射节点放置在消息流中。
To start to develop a mapping, place a mapping node in the message flow.
SAMLSOAP绑定描述了 SAML请求和响应消息交换如何映射到 SOAP 消息交换上。
The SAML SOAP binding describes how SAML request and response message exchanges are mapped onto SOAP message exchanges.
请参阅本文提供的示例项目，了解包括适当消息映射文件的消息集和流。
See the sample project provided with this article for message sets and a flow that includes an appropriate message mapping file.
为了在输出消息中创建重复的字段，首先要查看映射的输入消息，寻找重复所需次数的字段。
To create a repeating field in an output message, begin by looking at the map's input message to locate a field that repeats the desired number of times.
