Announcing WildFly Swarm 2017.6.0

WildFly Swarm 2017.6.0

In honor of National Doughnut Day, sink your teeth into the 2017.6.0 release of WildFly Swarm.

What’s New?

  • More YAML less main()

  • Update to WF Camel 4.7.0

What is WildFly Swarm?

WildFly Swarm is the decomposition and reconstitution of the popular WildFly Java Application Server in order to support just enough appserver for microservice type applications.

Each portion of the appserver is referred to as a fraction, which many times maps to a subsystem from WildFly, but also may include other discrete chunks of non-Java EE or WildFly functionality, such as Swagger, or Jolokia.

More YAML less main()

In our continued efforts to remove custom main() usage, we have two further improvements to help.

@Configurable support for Deployments

We’ve now made it possible for @Configurable to be applied to properties within a deployment.

For now we’ve made these changes in the Swagger fraction, but further fractions will come soon. So what do the changes mean?

Instead of needing a custom main() to do:


it’s now possible to use YAML:

             - org.wildfly.swarm.examples.jaxrs.swagger

The full list of YAML configuration for Swagger can be found here.

Deploy Artifacts by GAV

We can now also deploy artifacts that are dependencies in pom.xml as well:


In this case the version of the artifact is pulled in from the dependency entry in the pom.xml.

A full example can be found here.
