红帽全球峰会121.11. 用于 IDoc 的 XML Serialization
IDoc 消息正文可以序列化为 XML 字符串格式，以帮助内置类型转换器。
121.11.1. XML 命名空间
每个序列化 IDoc 都与 XML 命名空间关联，其具有以下通用格式：
http://sap.fusesource.org/idoc/repositoryName/idocType/idocTypeExtension/systemRelease/applicationRelease
http://sap.fusesource.org/idoc/repositoryName/idocType/idocTypeExtension/systemRelease/applicationReleaserepositoryName （远程 SAP 元数据存储库的名称）和 idocType (IDoc document type)都是强制的，但命名空间的其他组件可以留空。例如，您可以有一个类似如下的 XML 命名空间：
http://sap.fusesource.org/idoc/MY_REPO/FLCUSTOMER_CREATEFROMDATA01///
http://sap.fusesource.org/idoc/MY_REPO/FLCUSTOMER_CREATEFROMDATA01///121.11.2. 内置类型转换器
Camel SAP 组件具有一个内置类型转换器，能够将 Document 对象或 DocumentList 对象转换为 String 类型或从 String 类型转换。
例如，要将 Document 对象序列化为 XML 字符串，只需将以下行添加到 XML DSL 中的路由中：
<convertBodyTo type="java.lang.String"/>
<convertBodyTo type="java.lang.String"/>
您还可以使用此方法将 XML 消息序列化为 Document 对象。例如，如果当前消息正文是序列化 XML 字符串，您可以通过将以下行添加到 XML DSL 中的路由来将其转换为 Document 对象：
<convertBodyTo type="org.fusesource.camel.component.sap.model.idoc.Document"/>
<convertBodyTo type="org.fusesource.camel.component.sap.model.idoc.Document"/>121.11.3. XML 格式的 IDoc 消息正文示例
当您将 IDoc 消息转换为 String 时，它将序列化为 XML 文档，其中 root 元素是 idoc:Document （单个文档）或 idoc:DocumentList （用于文档列表）。它显示，单个 IDoc 文档已序列化为 idoc:Document 元素。
