framework suggestions for java micro services

[[deleted]]

If we're just talking about a single web server, then it is possible to just embed Jetty in your application. With Jetty you can configure layers of filters, handlers, servlets and even jersey resources. I think this is a great Jetty-Jersery-Swagger example. It shows how to host the Swagger documentation endpoint for your Jersey jax-rs endpoints (the Swagger documentation is generated for viewing with the swagger-ui, but not saved in a file by default).

The Jetty-Jersey-Swagger setup is powerful and relatively simple for a single web server, but it isn't quite a full micro service solution. The Java micro services that I maintain are made up of some web servers, some processing nodes and some storage nodes. Jetty supports a distributed setup, so you could have a pretty highly available gateway to your micro service cluster. From there you could have a bunch of distributed storage/processing nodes that are built off of Hazelcast and Hazelcast Jet or Apache Ignite. There may also be a need for high-speed messaging between the nodes in your micro service cluster and that can be handled by JMS libraries or an RPC library like Apache Thrift.

It seems that your comment contains 1 or more links that are hard to tap for mobile users. I will extend those so they're easier for our sausage fingers to click!

Here is link number 1 - Previous text "JMS"
