如何在Mule通用端點上設置屬性輪詢頻率

Question

我在我的流上使用的通用端點應該是測試文件和生產中的ftp。

我從屬性文件中獲取地址，並且此時它正常工作。問題是，當它作爲一個ftp端點工作時，我需要設置pollingFrequency，它在ftp：inbound-endpoint元素中有一個特定屬性，但不在通用端點中。

我正在試着用下面的代碼來做，但是我得到了底部的錯誤。看看這裏的文檔：http://www.mulesoft.org/documentation/display/current/Endpoint+Configuration+Reference，但它有點含糊。歡迎任何建議。

在騾子流動的元件：

<inbound-endpoint address="${source.address}" 
     responseTimeout="${source.response_timeout}" doc:name="Generic1" 
     mimeType="text/xml" exchange-pattern="one-way"> 
     <properties> 
      <property key="pollingFrequency" value="${source.polling_frequency}" /> 
     </properties> 
    </inbound-endpoint>

和異常，當我啓動服務器：

org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'property'. One of '{"http://www.springframework.org/schema/beans":description, "http://www.springframework.org/schema/beans":entry}' is expected.

該錯誤信息顯示，你可以使用彈簧：入門，所以試試：

<properties> 
    <spring:entry key="pollingFrequency" value="${source.polling_frequency}" /> 
</properties> 

（假設你有映射到默認spring前綴，當然春天命名空間......）
