Log4j更多的收集二
如果想在控制台输出信息,直接用system.out.println("");文件里输出debug就用logger.info("");
Java code log4j.rootCategory = debug,stdout,A2 log4j.appender.stdout = org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout = org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern =% d{yy - MM - dd HH:mm:ss.SSS} % 5p % x - % m % n # 设置A2为文件输出 log4j.appender.A2 = org.apache.log4j.RollingFileAppender # 设置输出路径、文件名 log4j.appender.A2.File = . / log / info.log # 设置输出编码 log4j.appender.A2.Encoding = GB2312 # 设置输出是否缓冲 log4j.appender.A2.BufferedIO = false # 设置输出缓冲区大小 log4j.appender.A2.BufferSize = 1024 # 设置输出文件名最大尺寸 log4j.appender.A2.MaxFileSize = 500KB # 设置输出文件备份个数 log4j.appender.A2.MaxBackupIndex = 1 # 设置A2使用PatternLayout log4j.appender.A2.layout = org.apache.log4j.PatternLayout # 设置A2的输出格式 log4j.appender.A2.layout.ConversionPattern =% d{yy - MM - dd HH:mm:ss} %- 5p % 16c{ 1 } % 3x - % m % n ### set log levels ###log4j.rootLogger = debug , stdout , D , E### 输出到控制台 ###log4j.appender.stdout = org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.Target = System.outlog4j.appender.stdout.layout = org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern = %d{ABSOLUTE} %5p %c{ 1 }:%L - %m%n### 输出到日志文件 ###log4j.appender.D = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.D.File = logs/log.loglog4j.appender.D.Append = truelog4j.appender.D.Threshold = DEBUG ## 输出DEBUG级别以上的日志log4j.appender.D.layout = org.apache.log4j.PatternLayoutlog4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n### 保存异常信息到单独文件 ###log4j.appender.D = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.D.File = logs/error.log ## 异常日志文件名log4j.appender.D.Append = truelog4j.appender.D.Threshold = ERROR ## 只输出ERROR级别以上的日志!!!log4j.appender.D.layout = org.apache.log4j.PatternLayoutlog4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
