springboot log多环境配置方式

前言 

bootstrap.yml（bootstrap.properties）与application.yml（application.properties）执行顺序

• bootstrap.yml（bootstrap.properties）用来程序引导时执行，应用于更加早期配置信息读取，如可以使用来配置application.yml中使用到参数等
• application.yml（application.properties) 应用程序特有配置信息，可以用来配置后续各个模块中需使用的公共参数等。
• bootstrap.yml 先于 application.yml 加载

1.第一种方法

直接写在application.yml里面，也能适配环境修改，但是只能使用默认一些策略，比如10M切分一个文件。

#日志配置
logging:
  level:
    root: INFO
  file: /home/xxx/logs/xxx.log

2.第二种方法

logback-spring.xml

<?xml version="1.0" encoding="utf-8"?>
<!--  Level	描述
     ALL	各级包括自定义级别
     ERROR	错误事件可能仍然允许应用程序继续运行
     FATAL	指定非常严重的错误事件，这可能导致应用程序中止
     INFO	指定能够突出在粗粒度级别的应用程序运行情况的信息的消息
     OFF	这是最高等级，为了关闭日志记录
    TRACE	指定细粒度比DEBUG更低的信息事件
    WARN	指定具有潜在危害的情况
    scan:当此属性设置为true时，配置文件如果发生改变，将会被重新加载，默认值为true。
    scanPeriod:设置监测配置文件是否有修改的时间间隔，如果没有给出时间单位，默认单位是毫秒。当scan为true时，此属性生效。默认的时间间隔为1分钟。
    debug:当此属性设置为true时，将打印出logback内部日志信息，实时查看logback运行状态。默认值为false。-->
<configuration debug="true" scan="true" scanPeriod="30 seconds">
    <!-- 存放日志文件路径  该 <springProperty> 标签允许我们从Spring中显示属性-->
    <springProperty scope="context" name="logHome" source="log.path"/>

        <!-- 根据时间来制定滚动策略 TimeBasedRollingPolicy-->

    <!-- ERROR级别-->
    <appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <!--如果只是想要 ERROR 级别的日志，那么需要过滤一下，默认是 INFO 级别的，ThresholdFilter-->
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">

        </filter>

    <root level="info">
        <appender-ref ref="consoleLog"/>
        <appender-ref ref="fileInfoLog"/>
        <appender-ref ref="fileErrorLog"/>
    </root>
</configuration>

一开始在application.yml 配置了log路径，但是springProperty 标签里面并没有获取到，会见在jar包存放的文件夹下，新建logHome_IS_UNDEFINED/%d/info/info.log，看下启动日志（一部分）：

13:44:32,739 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy@992086987 - No compression will be used

13:44:32,748 |-INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - Roll-over at midnight.

所以我在bootstrap.yml配置log.path来解决这个问题。

log:
  path: F:/logs/local-preferential
---
spring:
  profiles: test
log:
    path: /home/xxx-test/logs
---
spring:
  profiles: prod
log:
  path: /home/xxx/logs

启动打印log配置日志（一部分）

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
