263.17. 使用带有 Camel 路由的 Blueprint 属性占位符
可作为 Camel 2.7 提供
Camel 支持蓝图还提供属性占位符服务。Camel 支持有关配置的惯例,因此您必须做的一点是定义 XML 文件中的 OSGi Blueprint 属性占位符,如下所示:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.0.0" xsi:schemaLocation=" http://www.osgi.org/xmlns/blueprint/v1.0.0 https://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd"> <!-- OSGI blueprint property placeholder --> <cm:property-placeholder id="myblueprint.placeholder" persistent-id="camel.blueprint"> <!-- list some properties as needed --> <cm:default-properties> <cm:property name="result" value="mock:result"/> </cm:default-properties> </cm:property-placeholder> <camelContext xmlns="http://camel.apache.org/schema/blueprint"> <!-- in the route we can use {{ }} placeholders which will lookup in blueprint as Camel will auto detect the OSGi blueprint property placeholder and use it --> <route> <from uri="direct:start"/> <to uri="mock:foo"/> <to uri="{{result}}"/> </route> </camelContext> </blueprint>
263.17.1. 在 Camel 路由中使用 OSGi 蓝图属性占位符
默认情况下,Camel 会检测并使用 OSGi 蓝图属性占位符服务。您可以通过在 < camelContext
> 定义中将属性 useBlueprintPropertyResolver
设置为 false 来禁用此功能。
