之前客户端程序由于Websockt包依赖的log4j,就用log4j写日志了,Web用的log4j2没毛病。用log4j的多个logger的日志都写到一个文件里了,查了很多资料都没解决。今天闲了解决一下。
最后好使的配置
javascript
# 设置日志根
log4j.rootLogger = INFO,Exception,Debug
# additivity的作用在于 children-logger是否使用 rootLogger的配置,默认是开启true
log4j.addivity.org.apache=false
# 输出到日志文件
log4j.logger.Exception=INFO,Exception
log4j.additivity.Exception = false
log4j.appender.Exception.encoding=UTF-8
log4j.appender.Exception = org.apache.log4j.DailyRollingFileAppender
log4j.appender.Exception.File = logs/Exception.log
log4j.appender.Exception.Append = true
log4j.appender.Exception.Threshold = INFO
log4j.appender.Exception.layout = org.apache.log4j.PatternLayout
log4j.appender.Exception.ImmediateFlush=true
log4j.appender.Exception.BufferedIO=false
log4j.appender.Exception.BufferSize=0
log4j.appender.Exception.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] %m%n
log4j.logger.Debug=INFO,Debug
log4j.additivity.Debug = false
log4j.appender.Debug.encoding=UTF-8
log4j.appender.Debug = org.apache.log4j.DailyRollingFileAppender
log4j.appender.Debug.File = logs/Debug.log
log4j.appender.Debug.Append = true
log4j.appender.Debug.Threshold = INFO
log4j.appender.Debug.layout = org.apache.log4j.PatternLayout
log4j.appender.Debug.ImmediateFlush=true
log4j.appender.Debug.BufferedIO=false
log4j.appender.Debug.BufferSize=0
log4j.appender.Debug.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] %m%n
关键点是logger第一位是日志级别
各种查资料和问了人工智能,那东西问常规的还行,稍微偏一点的问题就跟人工智障一样
log4j2采用滚动日志配置和限制每个日志文件的大小
写日志工具类
java
package Monitor.Util;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
* 写日志工具类
*/
public class LogUtils {
//调试日志
static final Logger loggerDebug = LoggerFactory.getLogger("Debug");
//异常日志
static final Logger exceptionDebug = LoggerFactory.getLogger("Exception");
/**
* 书写调试日志
* @param message 日志内容
*/
public static void WriteDebugLog(String message)
{
loggerDebug.info(message);
}
/**
* 书写异常日志
* @param message 描述
* @param exception 异常
*/
public static void WriteExceptionLog(String message, Exception exception)
{
exceptionDebug.error(message, exception);
}
}
