Question

当我尝试使用prop命名空间（http://camel.apache.org/schema/placeholder）解析少数属性作为xs：int值时，如骆驼文档（http://camel.apache.org/using-propertyplaceholder.html）中所述，我面临以下问题，其中bundle转到“ GRACEPERIOD “尝试解析命名空间时。

以下是我正在使用的蓝图xml

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:camel="http://camel.apache.org/schema/blueprint"

           placeholder-prefix="$(" placeholder-suffix=")"/> 
<cm:property-placeholder id="id1" persistent-id="instance" placeholder-prefix="${" placeholder-suffix="}"/>

<camel:camelContext id="blueprintContext" trace="false"
    xmlns="http://camel.apache.org/schema/blueprint" streamCache="true"
    handleFault="false" useBreadcrumb="false" useBlueprintPropertyResolver="false">

    <!-- Disable jmxAgent to improve performance. This needs to be enabled 
        only when the flow needs to be seen via hawtio -->
    <camel:jmxAgent disabled="true" />


    <camel:threadPoolProfile
        id="changedProfile"
        defaultProfile="true"
        prop:poolSize="camel.thread.poolSize"
        prop:maxPoolSize="camel.thread.maxPoolSize"
        prop:maxQueueSize="camel.thread.maxQueueSize"/>

</camel:camelContext>

请帮我找到如何解决蓝图中的命名空间。

使用的版本：


Camel Core：2.10.0.redhat-60024

Camel Blueprint：2.10.0.redhat-60024

Jboss Fuse：6.0.0.redhat-024

我认为它永远无法在您的设置中运行。

您关联的网页using propertyplaceholder明确指出：

在XML DSL中使用任何属性的属性占位符
自Camel 2.7起可用如果您使用OSGi蓝图，那么这仅适用于 2.11.1 或 2.10.5 。

旧版本的JBoss Fuse提供 2.10.0

您应升级到最新的JBoss保险丝目前最新版本为6.3.0，Camel 2.17.0

在camel蓝图中使用“prop”命名空间来解析属性
