1) The application classpath has been properly configured with a logging provider (e.g. SLF4J and Logback) and an associated adapter/bridge JAR between Log4j (used by Apache Geode for logging) and your Spring application's logging provider if not Log4j itself (e.g. org.apache.logging.log4j:log4j-to-slf4j) along with...
2) A logging provider configuration file (e.g. logback.xml) ...
Then Apache Geode will not log any output at all.
SDG's old @EnableLogging annotation not longer has any effect given the recent logging behavioral changes in Apache Geode since 1.9.2. See DATAGEODE-299 for more details.
This improvement would include:
1) New Spring Boot starters to enable logging for Apache Geode and Pivotal GemFire, respectively: spring-geode-starter-logging and spring-gemfire-starter-logging.
2) These new Spring Boot logging starters would additionally include the org.springframework.boot:spring-boot-starter-logging, by default.
NOTE: the spring-boot-starter-logging dependency also adds the appropriate adapter/bride JAR (i.e. org.apache.logging.log4j:log4j-to-slf4j) to the application classpath.
4) Additionally, users will be able to adjust the log level for Apache Geode since the org.apache.geodeLoggerlog-level will be parameterized using a property (for example) that can be set in Java System Properties when launching the Spring Boot application. This property will have a name of spring.boot.data.geode.log.level.
Now that Apache Geode logging only works when...
