log4go

log4go

a logkit like as log4j with go language

Introduce

This project is come from an unmaintained fork, the branch can see http://log4go.googlecode.com

• left only so it doesn't break imports.
• some enhancement if to need

Usage:

• Add the following import: import l4g "github.com/gohutool/log4go"
• log4go configuration sample

  <!-- additivity 这个默认是true，即继承父类 root logger -->
  <!-- 也就是说，你的这个日志也会在root的logger里面输出的，我这里配置false，就是不继承，各走各的。 -->
  <!-- appender-ref 也就是说这个logger的输出目的地是哪里，ref就是关联到上面声明的一个file，一个console -->
  <logger name="com.ginghan">
    <level>info</level>

    <appender-ref ref="file" />
  </logger>

  <!-- 输出级别是info级别及以上的日志，下面的ref关联的两个appender没有filter设置，
  所以，info及以上的日志都是会输出到这2个appender的 -->
  <root>
    <level>info</level>
    <appender-ref ref="testfile" />
    <appender-ref ref="logstash" />
