Значение свойства не является доступом - PullRequest

ребята.

Я новичок для верблюда. У меня есть проблемы.

Мы внедряем систему передачи файлов с использованием верблюда.

Я устанавливаю свойство из внешнего файла свойств.

Но приложение не имеет доступа к этому файлу свойств. Мы не можем использовать propertyplaceholder, потому что значение будет изменено во время выполнения.

Мы реализовали это, как показано ниже.

camelContext.xml

<bean id="myProperties" class="java.util.Properties"/>
<bean id="propertylist" 
 class="org.apache.camel.component.properties.PropertiesComponent">
     <property name="cache" value="true"/>
     <property name="location" value="classpath:camelap.properties"/>
     <property name="overrideProperties" ref="myProperties"/>
</bean>
<camelContext id="camelContext-f611cb6c-d516-4346-9adc-5512d327a88d"
 trace="false" xmlns="http://camel.apache.org/schema/spring">
     <camel:route id="initial_info">
         <camel:from id="_initial" uri="direct:sqlParam"/>
         <camel:to id="_selectReference" uri="sql:{{sql.referenceInfo}}? 
          dataSource=dataSource"/>
         <camel:process id="_process1" ref="tempBean"/>
         <camel:log id="_aaaa" loggingLevel="WARN" message="tttttttt ::: 
          {{test}} ::: ${header.sourceDirectory}"/>
     </camel:route>

Если вы хотите использовать компонент свойств, вам нужно связать имя со свойствами, вот так:

<camelContext trace="{{foo.trace}}" xmlns="http://camel.apache.org/schema/spring">
    <propertyPlaceholder id="properties" location="org/apache/camel/spring/processor/myprop.properties"/>
    <template id="camelTemplate" defaultEndpoint="{{foo.cool}}"/>
    <route>
        <from uri="direct:start"/>
        <setHeader headerName="{{foo.header}}">
            <simple>${in.body} World!</simple>
        </setHeader>
        <to uri="mock:result"/>
    </route>
</camelContext>

Не уверен, что если вы используете пружинную загрузку, существует простой способ использовать пружинную загрузку properties в Camel Маршрут .
