java - log4j : current time in milliseconds

Question

asked Oct 17, 2021 in Technique[技术] by 深蓝 (71.8m points)

In log4j.properties I can set PatternLayout e.g. ("[%p] %c - %m - %d %n")

Is there any symbol (%something) which returns current time in milliseconds?

You can try this one.

log4j.appender.appender_name.layout=org.apache.log4j.PatternLayout
log4j.appender.appender_name.layout.ConversionPattern=%d %p [%c] - %m%n

Date params %d. For example : %d{HH:mm:ss,SSS}.
