springboot log configuration Spring Boot Series - Logging Configuration

springboot default is logback to remember log. Every time I see the first print out the log when you start the following services:

"C:\Program Files\Java\jdk1.8.0_40\bin\java.exe" ...
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/D:/workspace/m3/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]

If you do not do the logging configuration, the default is to generate spring.log in service.

 

To customize the logging configuration, simply put, can make use logging.file or logging.path make the following settings in application.properties in:

logging.file=logs/draft_spider.log
logging.level.com.draft.mapper= debug

 

Because a large amount of log different business systems, in order to facilitate rapid positioning of logs to troubleshoot problems, I want to print a business in a particular log file. Then, create logback.xml in the resources of the project, detailed logging.
