Support for configuration printers without requiring them to implement the
interface
------------------------------------------------------------------------------------
Key: FELIX-2649
URL: https://issues.apache.org/jira/browse/FELIX-2649
Project: Felix
Issue Type: New Feature
Components: Web Console
Affects Versions: webconsole-3.1.2
Reporter: Carsten Ziegeler
Assignee: Carsten Ziegeler
Fix For: webconsole-3.1.4
Currently if one wants to develop a configuration printer, the developed
component has to import/implement the configuration printer interface. This
ties the bundle to the web console bundle - which makes it more complicated to
implement such extensions than it should be.
For plugins we already have the dynamic registration without requiring to
implement a web console specific interface by searching for servlet services
with specific properties.
We could implement something similar for configuration printers:
We search for all services having at least these properties:
- felix.webconsole.label
- felix.webconsole.title
- felix.webconsole.configprinter.modes
If any service has these three properties *and* has a method
printConfiguration(PrintWriter) or printConfiguration(PrintWriter, String
(=mode)), this service is added as a configuration printer. This method is
searched by reflection.
