Spring Boot slf4j+logback日志框架使用

pom.xml中添加依赖

   org.slf4j
   slf4j-api


   ch.qos.logback
   logback-classic

 在resource下创建logback-spring.xml文件

<?xml version="1.0" encoding="UTF-8"?>






    

    logback

 然后在yml或者properties中配置

logging.config=classpath:logback-spring.xml
logging.path=D:/nmyslog/nmys

 添加日志打印信息

 打开日志输出的文件

刚才打印的日志信息
