# Getting started
1. define java service dsl using interface.
```java
@Service("greeting")
public interface GreetingService {
@ServiceMethod("once")
Mono sayHello(String name);
@ServiceMethod("many")
Flux sayHellos(String name);
@ServiceMethod("timer")
Flux timerHello(String name);
}
```
2. implement the service dsl.
```java
public class SimpleGreetingService implements GreetingService {
@Override
public Mono sayHello(String name) {
return Mono.just("greeting to: "+ name);
}
@Override
public Flux sayHellos(String name) {
return Flux.range(0, 3).map(i -> "greeting to: " + name + "-" + i);
}
@Override
public Flux timerHello(String name) {
return Flux.interval(Duration.ofSeconds(1)).map(i -> "greeting to: " + name + "-" + i);
}
}
```
3. running the service.
- RequestResponseMain
