springboot log多环境配置方式
作者：一克小白菜
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"/>
<!-- ch.qos.logback.core.ConsoleAppender 控制台输出 -->
<appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">
<!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符 -->
<pattern>%d [%thread] %-5level %logger{36} - %msg%n</pattern>
</layout>
</appender>
<!-- INFO级别 -->
<appender name="fileInfoLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
<!-- 级别过滤器：如果只是想要INFO级别的日志，只是过滤info还是会输出ERROR日志，因为ERROR的级别高，
所以我们使用下面的策略，可以避免输出ERROR的日志-->
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<!-- 过滤ERROR -->
<level>ERROR</level>
<!-- 匹配到就禁止 -->
<onMatch>DENY</onMatch>
<!-- 没有匹配到就允许 -->
<onMismatch>ACCEPT</onMismatch>
</filter>
<encoder>
<!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符 -->
<pattern>%d [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
<!--日志名称，如果没有File 属性，那么只会使用FileNamePattern的文件路径规则,如果同时有<File>和<FileNamePattern>，
那么当天日志是<File>，明天会自动把今天的日志改名为今天的日期。即<File> 的日志都是当天的。-->
<!-- 根据时间来制定滚动策略 TimeBasedRollingPolicy-->
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!--路径-->
<fileNamePattern>${logHome}/%d/info/info.log</fileNamePattern>
<!--保存最大天数-->
<maxHistory>30</maxHistory>
</rollingPolicy>
</appender>
<!-- ERROR级别-->
<appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
<!--如果只是想要 ERROR 级别的日志，那么需要过滤一下，默认是 INFO 级别的，ThresholdFilter-->
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>ERROR</level>
</filter>
<encoder>
<!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符 -->
<pattern>%d [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
<!-- 基于规模和时间的滚动策略 SizeAndTimeBasedRollingPolicy-->
<rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<!--路径-->
<fileNamePattern>${logHome}/%d/error/error.%i.log</fileNamePattern>
<!--保存最大天数-->
<maxHistory>30</maxHistory>
<!--文件最大值-->
<maxFileSize>2MB</maxFileSize>
<!--总大小上限-->
<totalSizeCap>10MB</totalSizeCap>
</rollingPolicy>
</appender>
<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

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。
