Dropwizard

Dropwizard is another technology for creating microservices in Java. It also has an opinionated approach, with a pre-selected stack that enhances an embedded Jetty servlet container with additional capabilities. The set of technologies that Dropwizard supports is comparatively narrow, though third-party or community-provided plugins are available to fill the gaps. Some of their capabilities, specifically their support for application metrics, are quite good.
