在駱駝藍圖中使用「prop」命名空間來解析一個屬性

當我嘗試使用prop名稱空間（http://camel.apache.org/schema/placeholder）解析駝峯文檔（http://camel.apache.org/using-propertyplaceholder.html）中的xs：int值時，我遇到了下面的問題，到「GRACEPERIOD」，當試圖解決命名空間。在駱駝藍圖中使用「prop」命名空間來解析一個屬性

09:08:35,325 | DEBUG | e-1.1.0-thread-1 | BlueprintContainerImpl   | 15 - org.apache.aries.blueprint.core - 1.0.1.redhat-60024 | Running blueprint container for bundle MyBundle

下面是藍圖XML我使用

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0" 
xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"

<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>

請幫我看看如何解決藍圖的命名空間。使用

版本：

駱駝核心：2.10.0.redhat-60024

駱駝藍圖：2.10.0.redhat-60024

Jboss的保險絲：6.0.0。 redhat-024

我認爲它永遠不會在y我們的設置。

您鏈接using propertyplaceholder頁中明確指出：

在XML DSL使用屬性佔位符屬性的任何一種
可用駱駝2.7
的。如果你使用OSGi的藍圖那麼這隻能從2.11.1或2.10.5上。

你的老版本的JBoss保險絲提供2.10.0

你應該升級到最新的JBoss保險絲。
此時最新版本是6.3.0與駱駝2.17.0
