Mule ESB 3.4 Context property

问题:

How can one access the properties loaded by context:place-holder in a scripting component other than having to use ${property-name}? I want to get to the object that holds these key value pairs. Something like context.getProperty("property-name").

回答1:

Spring property placeholders are resolved at configuration time and not stored anywhere, so they cant be loaded afterwards.

If you need to store it you can always inject them into a bean and retrieve that from the registry.

Basically all you need to do is to declare your bean:

<spring:bean class="your.Bean" name="yourBean" >    <spring:property name="yourBeanAttribute" value="${somePlaceHolder}" /> </spring:bean>

and then you can retrieve it, and the somePlaceHolder value from the registry from within a scripting component/transformer:

<scripting:transformer doc:name="Script">  <scripting:script engine="Groovy">   <scripting:text><![CDATA[ def val = muleContext.getRegistry().lookupObject('yourBean').getYourBeanAttribute() ]]></scripting:text>   </scripting:script>  </scripting:transformer>
