@Singleton
public class TestFunction extends FunctionInitializer {
Logger log = LoggerFactory.getLogger(TestFunction.class);
public TestFunction() {
}
public String execute() {
return "Hello";
}
}
I want to override datasource properties in application.yml file programmatically, but without using bean created event listener. Is there a way to do that. Like creating a custom application context with properties.
I have used the below approach for Micronaut API gateway proxy.
public class StreamLambdaHandler implements RequestStreamHandler {
.......
public StreamLambdaHandler() {
try {
log.info("Initializing Lambda Container");
this.dbCredentialService = new DBCredentialService();
// Get updated database credential map
Map<String, Object> props = this.dbCredentialService.getDbCredential();
// Create application context builder with updated properties
// i.e Override datasources properties in application.yml
builder = ApplicationContext.build().properties(props);
handler = new MicronautLambdaContainerHandler(builder);
}....
........
}
Can we do something similar with FunctionInitializer?
