Every application needs an administration console, and ours is no exception. In this article, we will build the AdministrationService to provide users with administration privileges to view, query, and control, various aspects of the application. Once constructed, we will exercise the service's Swagger interface and view the service's operational metrics using the AdministrationDashboard in Grafana.
During the lifetime of every user account, various events are generated and published to the application's message queue. It is advantageous to capture and persist these events to provide an audit log of an account's activity. In this article, we will build the AccountHistoryService which performs this task. In addition to capturing the account events, the service also provides a REST endpoint to query these events. After construction, we will deploy the application and exercise the generated Swagger interface. We then view the operational metrics using the AccountHistory Grafana dashboard.
For every registered user in the application, there exists a corresponding profile that contains application-specific information for that user. In this article, we construct the AccountProfileService, which is responsible for managing this data. The service provides a REST endpoint as well as a MessageQueue listener and persists the profile data in a MongoDB database. We will deploy the application and exercise its REST endpoint using the generated Swagger user interface. We wrap up by viewing the operational metrics using the AccountProfile Grafana dashboard.

In this third article discussing the AuthenticationService, we focus on the implementation of the core logic found in the AuthenticationService class and the JWTAuthorizationFilter, which intercepts service requests and verifies that each request has sufficient privileges to access the resource.
