logging(Forked from ngaut/log)

新增SetCallDepth方法,用于修改寻找调用函数对应的调用深度,以便对日志输出进行封装及自定义。

example：[https://github.com/heyHui2018/best-practise]

• 声明：

type LogP struct {
	TraceId string
}
log.SetCallDepth(5)

• 封装

func (l *LogP) logP(format string, v ...interface{}) {
	log.Infof(l.TraceId+" "+format, v)
}

• 调用：

l := new(LogP)
	l.TraceId = time.Now().Format("20060102150405") + utils.GetRandomString()
	l.logP("Register 完成,耗时 = %v", 123)

• 说明：
• 实现自定义
• 准确输出调用层级
