所以我承認我在applicationContext.xml中有很多事情要做，但我不知道爲什麼我無法添加另一個名爲publish.properties的屬性文件，並使用它以類似的方式，我現在有一個config.properties。我也有一個sensor.properties，但它的一組keyvalue對（並且在任何情況下它們都可以正常加載）。使用Camel加載多個屬性文件

我一直在閱讀駱駝屬性文檔，即http://camel.apache.org/properties.html但它仍然不清楚我如何指定多個屬性文件，以便駱駝可以解決它們。

這是我的一個運行電流applicationContext.xml中，並注入config.properties和sensor.properties就好：

我一直試圖在以下豆在我的applicationContext.xml添加到注入從我publish.properties六大領域文件到制定者/干將在我RandomEventGenerator類：

的「屬性」豆ID的變化而：

<bean id="publishProperties" 
     class="org.apache.camel.component.properties.PropertiesComponent"> 
    <property name="location" value="classpath:publish.properties"/> 
</bean>

我也試過這兩個屬性文件結合自己的特性豆ID裏面如下：

<bean id="properties" 
     class="org.apache.camel.component.properties.PropertiesComponent"> 
    <property name="locations" value="classpath:config.properties,classpath:publish.properties"/> 
</bean>

，但我仍然得到以下錯誤：

Could not resolve placeholder 'publish.makePub' in string value "${publish.makePub}"

但我記得，我不得不添加bridgePropertyPlaceholder以使config.properties可以在Spring中使用。有沒有一種方法可以爲config.properties和publish.properties共享這個橋樑？還是有更簡單的方法來做到這一點？

最終修復

的最後一個問題是，我沒有一個單獨的@Autowired注入兩類。有一次，我改變了這個代碼：

@Autowired 
    SensorEventStore sensorEventStore; 
    AdmissionEventStore admissionEventStore;

這樣：

@Autowired 
    SensorEventStore sensorEventStore; 
    @Autowired 
    AdmissionEventStore admissionEventStore;

一切正常注入。

我嘗試使用bridgePropertyPlaceholder屬性文件列表，現在我沒有得到駱駝或春天的錯誤。我添加了更新的applicationContext.xml到我的問題結束。但是，我仍然看不到我的publish.properties注入。當我嘗試向我的HelloWorld類中添加一個@Autowired來爲AdmissionEventStore類加載admission.properties時，我嘗試拉動這些屬性時出現錯誤。在我的applicationContext.xml中是否還有其他需要的東西？ – erj2code

你可以嘗試這樣的事：
