initialize camelContext properties

[alexey-s <al...@mail.ru>]

Hi

I read "Using proxy settings outside of URI" in
http://camel.apache.org/http4.html

<camelContext>
  <properties>
    <property key="http.proxyHost" value="172.168.18.9"/>
    <property key="http.proxyPort" value="8080"/>
  </properties>
</camelContext>

I read "Using Blueprint property placeholder with Camel routes" in
http://camel.apache.org/properties.html 
But I have not found a real example of the settings camelContext properties
from blueprint properties.


<cm:property-placeholder persistent-id="myblueprint.placeholder">
  <cm:default-properties>
    <cm:property name="http.proxyHost" value=""/>
    <cm:property name="http.proxyPort" value=""/>
  </cm:default-properties>
</cm:property-placeholder>

<camelContext>
  <properties>
    <property key="http.proxyHost" value="{{http.proxyHost}}"/>
    <property key="http.proxyPort" value="{{http.proxyPort}}"/>
  </properties>
  ...
</camelContext>

Easy to use text values ​​does not allow flexibility settings.

Yes, current camel property component doesn't support resolve the 
property value dynamically.
Do you mind to create a JIRA for it, I will work on this issue later 
this week.

I propose to replace the current structure
getCamelContext (). getProprties (). get("my_property")
to the new method
getCamelContext (). getProperty("my_property")

The implementation of this method will produce an automatic substitution
values ​​using property placeholders.

String getProperty (String name) {
   String value = getProperties().get(name);
   if (ObjectHelper.isNotEmpty (proxyUrl))
      value = resolvePropertyPlaceholders (value);
   return value;
}

Almost universally used property placeholders. Only in this place, this
mechanism is not in use.

For example, "Using proxy settings outside of URI", have no universal
solution. For each installation of the system must collect a unique jar
(OSGi bundle).

In this example, the xml has no universal solution. In Java DSL parameter
can be specified dynamically. In the xml this parameter is static.
