## CodedDFS.properties for LOGs in CodedDFS project

##

# Define the root logger

##

# 连接到根日志记录器的日志记录器，设置为INFO级别，在控制台显示，输出在滚动文件

# Console config

# 设置控制台显示ConsoleAppender

# Log4j的输出布局模式（Layout接口）

# 这里用的是PatternLayout,可以灵活的制定布局模式

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern format: Date LogLevel; LoggerName;   LogMessage;

# 输出格式：%d-时间；%p-logger级别；%c-类名{两级}；%m-调用logger时设定输出内容；%n-换行

log4j.appender.stdout.layout.ConversionPattern=%d{yy/MM/ddHH:mm:ss}%p%c{2}:%m%n

# Rolling File Appender = RFA

# Add " RFA " to rootlogger above if you want to use this

##

# 设置一个滚动日志文件 RollingFileAppender

# Define the output file is logs/BMBRFileSystem.log

# 输出到logs/BMBRFileSystem.log
