Get service annotations
The sample below shows how to retrieve all the annotations of a service:
@http:ServiceConfig { basePath: "/helloWorld" }
service hello on new http:Listener(9090) {
resource function hello(http:Caller caller, http:Request req) {
http:Response res = new;
res.setTextPayload("hello world");
var result = caller->respond(res);
}
}
reflect:annotationData[] annotations = reflect:getServiceAnnotations(hello);
string annoName = annotations[0].name; // E.g. “ServiceConfig”
string annoPkg = annotations[0].moduleName; // E.g. “ballerina.http”
