Subject [jira] Created: (CAMEL-2926) Injecting Properties into the PropertiesComponent with Spring
Date Thu, 08 Jul 2010 19:09:51 GMT
Injecting Properties into the PropertiesComponent with Spring
-------------------------------------------------------------

                 Key: CAMEL-2926
                 URL: https://issues.apache.org/activemq/browse/CAMEL-2926
             Project: Apache Camel
          Issue Type: Improvement
          Components: camel-core, camel-spring
    Affects Versions: 2.3.0
            Reporter: Ryan Callaghan
            Priority: Minor


The component is quite nice - however a good improvement would be allowing properties to be
injected through Spring.

Currently there are two ways to do this using Spring.

1) Declare a bean with an id of properties:
<bean id="properties" class="org.apache.camel.component.properties.PropertiesComponent">
    <property name="location" value="classpath:com/mycompany/myprop.properties"/>
</bean>

This would be improved if we could simply say:
<bean id="properties" class="org.apache.camel.component.properties.PropertiesComponent">
    <property name="location" ref="myPropertiesBean"/>
</bean>

This would allow properties to be declared in Spring using <util:properties/>.  The
same properties grouping could be injected into Camel as is injected into other beans.

2) Inline within the camelContext defined in Spring:
<camelContext ...>
   <propertyPlaceholder id="properties" location="com/mycompany/myprop.properties"/>
</camelContext>

Similarly it would be nice to say:
<camelContext ...>
   <propertyPlaceholder id="properties" ref="myPropertiesBean" />
</camelContext>

I noticed CAMEL-2791 is out there to access JVM system properties - it would be good to not
have to load as a system property to access them in Camel.
