JHipster Gateway with legacy REST service

Question

I've setup a POC with the following components:

• JHipster registry
• JHipster API gateway
• 2 JHipster microservices

The communication works very well between these components.

Another requirement of my POC is to register an legacy webservice(SOAP or REST not developed with JHipster) in the JHipster gateway. Is it possible? I would want to use the API Gateway as a unique entry point for all the clients(external and internal)to access all the webservices of my company. Thank you.

Answer 1

Two important criteria are service discovery and security.

For service discovery, JHipster offers 2 options: JHipster Registry (Eureka) and HashiCorp Consul. Consul is better suited for legacy apps as it is less invasive because you can use DNS resolution and templates and a sidecar proxy approach.

For security, legacy apps should be able to consume authentication tokens to apply authorizations.
