FINT Core Webhook

This project provides a simple approach to set up webhook client and webhook server functionality within a Spring Boot application. The main purpose is to enable a service (the client) to register callbacks with a remote server, perform health checks, and receive events via configured callback URLs.

Overview

The project is split into two parts:

1. Webhook Client

   • Handles registration of the client to the server
   • Subscribes to callbacks from the server
   • Implements periodic health checks

2. Webhook Server

   • Maintains a list of client callbacks
   • Provides an endpoint for clients to register
   • Performs health checks to ensure client callbacks are valid
   • Sends events back to client callbacks

Webhook Client usage

1. Annotate your Application with @WebHookClient
2. Create a bean of WebHookClientService with the specified type that should be processed.

    @Bean
    fun webHookClientService(objectMapper: ObjectMapper): WebhookClientService<Test> {
        return WebhookClientService(Test::class.java, this::test, objectMapper)
    }

    fun test(test: Test) {
        // handle test
    }

}

Webhook Server usage

1. Annotate your Application with @WebHookServer
2. Dependency Inject WebHookServerService and call callback

    fun test() {
        webHookServerService.callback(Testt("OK", "BINGO"))
    }
