THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
...
- Any properties specified in the @Service annotation are used to provide the OSGi Service
- Any properties provided by a FactorySet are also inserted in the published service
- Any Dependency whose propagate attribute is set to true will also insert its properties to the published service
But there is also a use case where your own component might want to dynamically specify the list of properties which should be also inserted in the published service, and you can do this by returning an optional Map from your @Start callback methodwhen the component needs to specify some service properties dynamically (not statically from the annotation), then it may does so by just returning a Map from the @Start callback. For instance:
| Code Block |
|---|
@Service(properties={@Property(name="foo", value="bar")})
public class MyServiceImpl implements MyService {
@ConfigurationDependency(pid="MyPid", propagate=true)
void updated(Dictionary conf) {
// "conf" contains foo2=bar2, for example, and since we have set the "propagate" attribute to true, then
// the property will be propagated to our published service ...
}
@Start
Map start() {
// Return some extra properties to be inserted along with our published properties. This map takes
// precedence, and may override some properties specified in our @Service annotation, or some properties
// propagated from our @ConfigurationDependency dependency ...
return new HashMap() {{ put("foo3", "bar3"); }};
}
}
