Logger日誌
阿新 • • 發佈:2018-12-06
日誌體系 log4j log4j2(mybatis用到) jul (javautillogging,spring用到) logback(springboot用到) jcl(commons-logging) 抽象日誌。 "org.apache.commons.logging.impl.Log4JLogger", "org.apache.commons.logging.impl.Jdk14Logger", "org.apache.commons.logging.impl.Jdk13LumberjackLogger", "org.apache.commons.logging.impl.SimpleLog" Log log = LogFactory.getLog("jcl"); //得到的是log4j物件 slf4j (使用log繫結器去繫結log物件) 核心+繫結器 - log4j binding ---> log4j - jul binding ---> jul - jcl binding ---> jul log4j... - logback binding ---> logback slf4j 橋接器 - jcl-over-slf4j 將jcl日誌,改用為slf4j日誌 - log4j-over-slf4j 將log4j日誌,改用slf4j日誌(有問題,需要自己解決)
