One Minute Introduction

Blammo will typically expect implementations of logger interfaces to be available on the classpath. The Blammo Maven plugin allows these implementations to be generated without any effort.

How does it work?

The Maven plugin will scan the directory containing the Java sources, looking for Java interfaces marked with the '@blammo.logger' annotation. It will take these interfaces, and generate an implementation class using the other @blammo annotations, as well as a properties file containing the actual messages.

  • For every log message, the plugin will generate a method.
  • This method will first of all call the underlying logging mechanism (JDK, Log4j, ...) to find out if anything should be logged at all.
  • After that, it will compose the message by loading the message from a ResourceBundle, and substitute variables in the message by the values of parameters passed to the logging operation.
