3.添加日志logback(多环境)

四.添加日志logback(多环境)

4.1拆分application.properties

拆分为开发环境application-dev.properties和正式环境application-pro.properties

根据不同环境的数据库登登不同配置，application.properties保留多环境相同的配置

application.properties

#切换环境
spring.profiles.active=dev 
logging.config=classpath:logback-${spring.profiles.active}.xml

4.2拆分logback.xml

将logback.xml文件拆分为logback-dev.xml，logback-pro.xml两个文件

logback-dev.xml (开发环境只需要打印控制台)

<?xml version="1.0" encoding="utf-8"?>
<configuration scan="true" scanPeriod="60 seconds" debug="false">
    <springProperty scope="context" name="common.logDir" source="common.logDir"/>

启动时指定：

java -jar xxx.jar --spring.profiles.active=dev

也可以在application.properties指定：

spring.profiles.active=dev
