Different log4j layout for debug and error?

由 不打扰是莪最后的温柔 提交于 2020-01-10 14:58:20
问题 In log4j, is there a way to have logger.error("") and logger.debug("") include different output layouts?

EDIT: After adding apache-log4j-extras, the following config file works. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd" > <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> <appender name="WARNINGS" class="org.apache.log4j

由 戏子无情 提交于 2020-01-10 05:14:08

Hibernate 3.4 with slf4j and log4j

由 可紊 提交于 2020-01-09 07:14:49
问题 I'm attempting to upgrade from Hibernate 3.2 to 3.4, which apparently uses slf4j. Our project currently uses log4j. So my assumption is that I should be using the slf4j-log4j12 wrapped implementation.
