在骆驼蓝图中使用“prop”命名空间来解析一个属性

当我尝试使用prop名称空间（http://camel.apache.org/schema/placeholder）解析驼峰文档（http://camel.apache.org/using-propertyplaceholder.html）中的xs：int值时，我遇到了下面的问题，到“GRACEPERIOD”，当试图解决命名空间。在骆驼蓝图中使用“prop”命名空间来解析一个属性

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

下面是蓝图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:jmxAgent disabled="true" /> 


    <camel:threadPoolProfile 
     id="changedProfile" 
     defaultProfile="true"

     prop:maxPoolSize="camel.thread.maxPoolSize" 
     prop:maxQueueSize="camel.thread.maxQueueSize"/> 

</camel:camelContext>

请帮我看看如何解决蓝图的命名空间。使用

版本：

骆驼核心：2.10.0.redhat-60024

骆驼蓝图：2.10.0.redhat-60024

Jboss的保险丝：6.0.0。 redhat-024

我认为它永远不会在y我们的设置。

您链接using propertyplaceholder页中明确指出：

在XML DSL使用属性占位符属性的任何一种
可用骆驼2.7
的。如果你使用OSGi的蓝图那么这只能从2.11.1或2.10.5上。

你的老版本的JBoss保险丝提供2.10.0

你应该升级到最新的JBoss保险丝。
此时最新版本是6.3.0与骆驼2.17.0
