# New Services Design
## Example of use:
System.setProperty("configFile.location","/opt/mcx/config/config.properties");
String appName = "testApp";
microservice.MicroserviceApp msApp = new microservice.MicroserviceApp(appName);
msApp.withMetrics()
.withMonitoring()
//.withDefaultServiceAuthorization()
.addService(Enums.EnumServiceType.E_REST,new IRestServiceUndertowImpl(new RestServerParams(32000, "localhost", 2),"undertowRestService")
.addMethod(Enums.EnumServiceType.E_REST,CommonServices.IRestService.E_READ,"/resource/r1",(msgCtx) -> {
BaseRestResponse brr;
brr.setObject({ "a":"b" })
msgCtx.writeResponse(brr);
})
.addMethod(Enums.EnumServiceType.E_REST,CommonServices.IRestService.E_READ,"/resource/r1",(msgCtx) -> {
BaseRestResponse brr;
msgCtx.writeResponse(brr);
})
.build()
.run();
### Flow for Service:
1 Receive Msg
2 Parse
3 Prepare MsgContext
4 Build ServiceKey
5 call reactor.delegate(serviceKey,msgContext)
6 Mitfanen :sleeping:
### Flow for Reactor:
1 find callback method from serviceKey
2 activate method
3 add for metrics,stats etc'

# new services design
- counters and metrics in the handler/reactor
- validateRequest in RestService , the jwt issues
- All the validation ,pre/post handling that was were done by the handler will be done by the base service
- add Runtime Test:
addTest(const char *testName, nsMicroservice_Iface::TestFunction testFunction);
addTest(nsMicroservice_Iface::ITest *p_testClass)
