Loggers

Content Integration Framework provides logging interface using the slf4j library. By adding dependency for the slf4j library, the plugins can use its API for adding loggers inside service implementations.

The starter as well as reference projects included in dev-kits manage their dependencies using Apache Maven. The following entry is found in the POM file:
<dependency>
		<groupId>org.slf4j</groupId>
		<artifactId>slf4j-api</artifactId>
		<version>1.7.26</version>
	</dependency>
Use 1.7.26 or higher version of slf4j-api to avoid conflict. Once the required dependency is added, the logger object can be obtained by directly accessing the slf4j API.
Logger log = LoggerFactory.getLogger(YOUR_CLASS.class);

Alternatively, project Lombok can also be used to get the logger object for your class. Lombok provides @Slf4j annotation, which can be used to inject the earlier mentioned property inside the annotated class. For more information on project Lombok, please visit its official web page.

Additionally, the application logs can be found in AssetPicker/logs directory under platform home. By default, all the loggers from your plugin will reside in the common log file configured in AssetPicker/conf/logging/log4j2.xml file. You can alter the log4j2.xml configuration file to route your loggers to a different file, for troubleshooting during development. Configuration of log4j2 is not part of the scope of this guide. Please refer to the official documentation of Apache Log4j2 for more information.
