常用的logback或log4j开发配置 ​

设置打印pattern ​

log4j.xml

这样打印的行更短idea也能查找对应的类比较方便排查

xml
<property name="LOG_PATTERN" value="%date{HH:mm:ss} %-5level %c{1.} - %msg%n"/>
<property name="LOG_PATTERN" value="%date{HH:mm:ss} %-5level %c{1.} - %msg%n"/>

logback-spring.xml

xml
<property name="DEFAULT_PATTERN"
              value="%date{yyyy-MM-dd HH:mm:ss.SSS}-%-5level-[%thread]%logger{20}: %message %n%exception{full}"/>
<property name="DEFAULT_PATTERN"
              value="%date{yyyy-MM-dd HH:mm:ss.SSS}-%-5level-[%thread]%logger{20}: %message %n%exception{full}"/>

打印特定模块的debug日志和durid的完整sql ​

durid配置: https://www.jsfr.work/Java语言相关/使用durid打印可执行sql.html

log4j.xml

xml

<logger name="druid.sql.Statement" additivity="true">
    <level>DEBUG</level>
</logger>
<logger name="com.xcrop" additivity="false" level="debug">
    <appender-ref ref="Console"/>
</logger>

<logger name="druid.sql.Statement" additivity="true">
    <level>DEBUG</level>
</logger>
<logger name="com.xcrop" additivity="false" level="debug">
    <appender-ref ref="Console"/>
</logger>

logback-spring.xml

xml
