Logback Custom Injection for Google Guice

Ever tried dependency injection while you still want class specific logging? If you don't want to break the sense of dependency injection you shouldn't use a static factory in each class. Google Guice even supports logger injection but sadly only for the default java.util.Logger. Be serious: Who really uses this in production on enterprise level? We wan't custom injection of our own logging framework. In this case we will use logback as our logging framework.

Usage

  • Install Maven
  • Clone this repo
  • Install: mvn clean install

Maven dependencies

<dependency>
    <groupId>de.felix-klauke</groupId>
    <artifactId>google-guice-logback</artifactId>
    <version>1.0-SNAPSHOT</version>
    <scope>compile</scope>
</dependency>

Example / How To

First you will have to install our module in your injector. You can put the module in the injector creation or install our module in your main module.

Injector injector = Guice.createInjector(new MyCoolModule(), new LogbackModule());
@Override
protected void configure() {
    install(new LogbackModule);
}

As soon as the module is installed you can use on any field:

@InjectLogback private Logger logger;
