日志级别

• Fatal 致命的
• Panic 严重的
• Error 错误的
• Warn 告警的
• Info 信息的
• Debug 调试的

文件说明

• log.go 对外开放的方法，默认console适配器，属于第1层级
• logger.go log对象，像 SetAdapter WithHook 是项目及全局方法，属于第2层级
• entry.go 实体类，每次产生一条log时，都要 new 实体类，主要处理消息内容、标签、附加数据等，属于第3层级
• message.go 消息内容对象，包装每条消息包含的字段信息
• adapter.go 适配器
• console.go 控制台适配器
• file.go 文件适配器
• file_options.go 文件适配器 选项

文件适配器

• filepath 日志保存目录
• filename 日志文件名，使用 yyyymmdd.log
• maxSize 文件大小最大值，默认512M，超过后，会切割文件
• FilePathOption() 定义文件路径
• FileMaxSizeOption() 定义文件大小最大值

输出对象

• console
• file
• kafka
• es
