Service Aggregator. Hello, dear friends. In this video we will integrate the system-info micro service and the user-info micro service. First I will create an interface. Through this interface I will specify the system-info micro service methods that I will use. I'm using the RegisterRestClient annotation. I am writing the other services Uri-info within the baseUri value. We can define it inside server.xml as well. I will make the interface  autocloseable so it can close automatically after being used. I define each method as corresponding to the system-info service. Okay, all defined. Now, I will create an application being class. I write a named annotation here as well. I will use this class methods in my user interface page. I'm injecting our integrator interface, we will use some methods of it. I'm defining the getJwt method. I am defining the getOs method. I am defining the getUsername method. Lastly, I'm defining a method to get roles. All right, dear friends, we will integrate two service projects. In the next video, we will design a simple user interface with JSF. So, I'll see you in the next lesson.
