Vert.x Logging

I find this much preferable to the JUL logger, which requires string concatenation to accommodate the same thing:

To set Log4j2 dependencies in your pom.xml, include the following:

and refer to your logger exactly as you would with any other factory, by importing the vertx logger:

What’s important to note is that the vert.x launcher initializes the logger factory before your verticle starts. In other words, you can’t programmatically set a system property in your verticle implementation. Also note that you cannot set the system property in your pom.xml when using the fabric8 Maven plugin:

$ mvn package vertx:run

will not work. Not sure if this is a bug or expected behaviour but I am hoping to spare some cycles some time to look into it.
