Spring boot 应用 log 文件配置 Sample

一个例子.

src/main/resources/logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">
   <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
      <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
         <!--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{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
      </encoder>
   </appender>
   <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
      <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
         <FileNamePattern>./out/app.%d{yyyy-MM-dd}.%i.log</FileNamePattern>
         <maxFileSize>200MB</maxFileSize>
         <MaxHistory>0</MaxHistory>
      </rollingPolicy>
      <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
         <!--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{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
      </encoder>
   </appender>
   <!-- 日志输出级别 -->
   <root level="INFO">
      <appender-ref ref="STDOUT" />
      <appender-ref ref="FILE" />
   </root>
   <springProfile name="dev">
      <logger name="org.hibernate.SQL" level="DEBUG" />
   </springProfile>
</configuration>
