|
|
* 日志重定向输出
|
|||
|
|
* 1. 支持动态启动和停止
|
|||
|
|
* 2. 支持日志存储的目录
|
|||
|
|
* 3. 支持网络发出打印日志
|
|||
|
|
* 4. 支持输出日志上下文信息比如所在代码文件、行号、函数名等
|
|||
|
|
* 5. 支持设置日志文件大小限制，超过则自动分文件，默认128kb
|
|||
|
|
* 6. 支持按照日志行数自动分文件，和日志大小条件互斥
|
|||
|
|
* 7. 可选按照日期时间区分文件名存储日志
|
|||
|
|
* 8. 日志文件命名规则优先级：行数>大小>日期
|
|||
|
|
* 9. 自动加锁支持多线程
|
|||
|
|
* 10. 可以分别控制哪些类型的日志需要重定向输出
|
|||
|
|
* 11. 调用函数start()启动服务，stop()停止服务
