logback

1. logback.xml 配置

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
      <encoder>
        <pattern> %5p [%15.15t] %-40.40logger{39} : %m%n</pattern>
          <charset>utf8</charset>
        </encoder>
      </appender>
      <logger name="xxx.yyy.zzz" level="DEBUG" additivity="false">
        <appender-ref ref="CONSOLE"/>
      </logger>
    <root level="WARN">
      <appender-ref ref="CONSOLE" />
    </root>
</configuration>

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

    <property name="LOG_PATH" value="${catalina.base}/logs/webapps"/>
    <property name="LOG_FILE" value="${LOG_PATH}/spring.log"/>

    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss} %5p [%15.15t] %-40.40logger{39} : %m%n</pattern>
            <charset>utf8</charset>
        </encoder>
    </appender>

    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %5p [%15.15t] %-40.40logger{39} : %m%n</pattern>
            <charset>utf8</charset>
        </encoder>
        <file>${LOG_FILE}</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
            <fileNamePattern>${LOG_FILE}.%d{yyyy-MM-dd}.%i.gz</fileNamePattern>
            <maxFileSize>10MB</maxFileSize>
            <maxHistory>0</maxHistory>
        </rollingPolicy>
    </appender>

    <!-- 指定类与 <looger> 的关联关系 -->
    <logger name="com.sxnd" level="DEBUG" additivity="false">
        <appender-ref ref="CONSOLE"/>
        <appender-ref ref="FILE" />
    </logger>

    <root level="INFO">
        <appender-ref ref="CONSOLE" />
        <appender-ref ref="FILE" />
    </root>

</configuration>

2. Spring Boot 中的日志配置

logging:
  level:
    root: WARN
    com.woniu: DEBUG
    com.example: DEBUG
  pattern:
    console: "${CONSOLE_LOG_PATTERN:\
      %clr(${LOG_LEVEL_PATTERN:%5p}) \
      %clr([%15.15t]){faint} \
      %clr(%-40.40logger{39}){cyan} \
      %clr(:){faint} \
      %m%n${LOG_EXCEPTION_CONVERSION_WORD:%wEx}}"

注意

这里的 console 配置 “有” 双引号。

logging.level.root=WARN
logging.level.com.woniu=DEBUG
logging.level.com.example=DEBUG
logging.pattern.console=${CONSOLE_LOG_PATTERN:\
    %clr(${LOG_LEVEL_PATTERN:%5p}) \
    %clr([%15.15t]){faint} \
    %clr(%-40.40logger{39}){cyan} \
    %clr(:){faint} \
    %m%n${LOG_EXCEPTION_CONVERSION_WORD:%wEx}}

注意

这里的 console 配置 “没有” 双引号。
