Error Handling

ServiceStack and it's new API provides flexible way to intercept exceptions. If you need a single entry point for all service exceptions, you can subscribe to AppHostBase.ServiceExceptionHandler events in Configure method like shown below:

    public override void Configure(Container container)
    {
        ServiceExceptionHandler += (request, exception) => {
            //log your exceptions here
            ...
            //call default exception handler or prepare your own custom response
            return DtoUtils.HandleException(this, request, exception);
        };
    }

If you have old services you still can handle all exceptions in one single place. Create base class for your services and override HandleException method like shown below.

public class MyServiceBase<TRequest> : RestService<TRequest>
{
   public override object HandleException(TRequest request, Exception exception)
   {
       //log your exceptions here
       ...
       //call default exception handler or prepare your own custom response
       return base.HandleException(request, exception);
   }
}
