Description

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.
