Almost every module in undertow-server has a configuration file that can be externalized with default can be in the module itself or the API implementation config folder. In order to give an overview of the server runtime, system properties, specification as well as configurations for each enabled modules, there is a special handler that can be included in your swagger specification.
info.json
{
"description": "Server info endpoint that can output environment and component along with configuration",
"enableServerInfo": true
}
Unlike other modules, server info handler is not plugin into the handler chain during server start up. It should be part of the swagger specification and route to this handler in the routing handler. If enableServerInfo is false, then an error message will returned with ERR10013 - SERVER_INFO_DISABLED.
Along with other endpoints/paths defined in the swagger specification, an extra endpoint should be added with special oauth2 scope for this handler. It is recommended to use /basePath/server/info so that some automatic tool or API portal server can access to it in a standard way.
For other contributed modules or API application specific modules, please following the following guideline to register your module in /basePath/server/info endpoint.
For handlers, it is registered when injecting into the handler chain during server start up. For other utilities, it should have a static block to register itself during server start up.
Here is the example code to register module and its config.
ModuleRegistry.registerModule(ValidatorHandler.class.getName(), Config.getInstance().getJsonMapConfigNoCache(ValidatorHandler.CONFIG_NAME), null);
When module registers itself, it provide the configuration in JSON format for the module. Some components have sensitive info in their configuration, for example, db password, client secret etc. The third parameter in registerModule is a list of keys in the configuration file that need to be masked.
Here is an example.
List<String> masks = new ArrayList<String>();
masks.add("trustPass");
masks.add("keyPass");
ModuleRegistry.registerModule(Client.class.getName(), Config.getInstance().getJsonMapConfigNoCache(CONFIG_NAME), masks);
Here is the output from undertow swagger-codegen petstore specification.
