How can I disable Spring logs to have log outputs that I can easily read or someone else can read. An answer to a similar question at, how to disable spring bean loading log
Your default logging, for everything that isn't explictily specified, is DEBUG. So everything is logged at that level (judging from your configuration), basically you are flooding your logs. You should not remove loggers for org.springframework you should add them and set another level for them.
log4j.logger.org.springframework=INFO
or whatever log level level you like.
