[ https://issues.apache.org/jira/browse/CAMEL-5438?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Willem Jiang resolved CAMEL-5438.
---------------------------------
Resolution: Fixed
Fix Version/s: 2.11.0
> Dynamic resolve property for CamelContext
> -----------------------------------------
>
> Key: CAMEL-5438
> URL: https://issues.apache.org/jira/browse/CAMEL-5438
> Project: Camel
> Issue Type: New Feature
> Components: camel-core
> Affects Versions: 2.10.0
> Reporter: Aleksey Sushko
> Assignee: Willem Jiang
> Fix For: 2.11.0
>
>
> If you read the description of the camel http4 component you can find an example set of parameters for a consumer.
> {code}
> <camelContext>
> <properties>
> <property key="http.proxyHost" value="172.168.18.9"/>
> <property key="http.proxyPort" value="8080"/>
> </properties>
> </camelContext>
> {code}
> In this example, the xml has no universal solution.
> I think that the universal solution is to use a property placeholder. In this case, you can use an external configuration.
> {code}
> <camelContext>
> <properties>
> <property key="http.proxyHost" value="{{http.proxyHost}}"/>
> <property key="http.proxyPort" value="{{http.proxyPort}}"/>
> </properties>
> </camelContext>
> {code}
> One possible solution is to replace the existing structure to access the property
> {code}
> String value = getCamelContext().getProperties().get("my_property");
> {code}
> Replace the call of the new method
> {code}
> String value = getCamelContext().getProperty("my_property");
> {code}
> Inside a method call to use the old design and a response sent to the method of resolvePropertyPlaceholders.
> {code:title=An example of implementation}
> public String getProperty(String name) {
> String value = getProperties().get(name);
> if(ObjectHelper.isNotEmpty(value))
> value = resolvePropertyPlaceholders(value);
> return value;
> }
> {code}
