log4j2

问题 Is there an equivalent of Enhanced Throwable Renderer class ( which was present in log4j1 ) in log4j2 ? I am migrating a library to log4j2 and I don't see this feature supported in log4j2. Any help is appreciated. 回答1: In log4j2, the PatternLayout has many options like %ex{option} , %rEx{option} or %xEx{option} that I suspect have the same functionality or more than Enhanced Throwable Renderer. 来源： https://stackoverflow.com/questions/29265634/enhanced-throwable-renderer-in-log4j2

问题 Does anyone know how to configure the log4j2.xml file to use log4jdbc? I have been searching for several hours and I can't seem to find anything. 回答1: log4jdbc relies on SLF4J. There is to date no proper connector between SLF4J and Log4j 2. If you want, you can instead use log4jdbc-log4j2, which addresses exactly this need of getting log4j2 to work with log4jdbc. 回答2: As of beta5, Log4j 2.0 does not offer a JDBC Appender. However, the team is working on one and it is likely that a subsequent

问题 I am trying to log stack traces into Logstash. The logging stack is ELK (ElasticSearch, Logstash, Kibana).
