SpringLog4jConfig.java

@Configuration
public class SpringLog4jConfig {

    /**
     * Just a property from the normal Spring property sources, like:
     * log4j.properties.location=log4j-dev.properties
     */
    @Value("${log4j.properties.location}")
    String log4jLocation;

    /**
     * Make sure the file specified by the log4j.properties.location value is on the classpath
     */
    @PostConstruct
    void initializeLog4j() throws FileNotFoundException {
        Log4jConfigurer.initLogging("classpath:" + log4jLocation);
    }
}
