news 2025/6/23 2:39:05

1、l4jlog.h封装头文件

#pragma once#include <iostream>
#include <log4cplus/logger.h>
#include <log4cplus/loggingmacros.h>
#include <log4cplus/fileappender.h>
#include <log4cplus/layout.h>
#include <log4cplus/configurator.h>
#include <log4cplus/ndc.h>
#include <log4cplus/helpers/loglog.h>
#include <log4cplus/helpers/property.h>
#include <log4cplus/initializer.h>#define MODULE_NAME			"ConsoleApplicationDemo"
#define CONFIG_PATH_NAME	"log4cplus.properties"class BaseLog
{
public:BaseLog() { log4cplus::PropertyConfigurator::doConfigure(CONFIG_PATH_NAME); };~BaseLog() {};log4cplus::Logger GetLogger() { return log4cplus::Logger::getInstance(MODULE_NAME); }static BaseLog &GetInstance() { static BaseLog instance; return instance; }private:log4cplus::Initializer initializer_;
};#define LOG_TRACE(...)		LOG4CPLUS_TRACE_FMT(BaseLog::GetInstance().GetLogger(), __VA_ARGS__) 
#define LOG_DEBUG(...)		LOG4CPLUS_DEBUG_FMT(BaseLog::GetInstance().GetLogger(), __VA_ARGS__) 
#define LOG_INFO(...)		LOG4CPLUS_INFO_FMT(BaseLog::GetInstance().GetLogger(), __VA_ARGS__) 
#define LOG_WARN(...)		LOG4CPLUS_WARN_FMT(BaseLog::GetInstance().GetLogger(), __VA_ARGS__) 
#define LOG_ERROR(...)		LOG4CPLUS_ERROR_FMT(BaseLog::GetInstance().GetLogger(), __VA_ARGS__) 
#define LOG_FATAL(...)		LOG4CPLUS_FATAL_FMT(BaseLog::GetInstance().GetLogger(), __VA_ARGS__)

2、ConsoleApplicationDemo.cpp文件

// ConsoleApplicationDemo.cpp : 定义控制台应用程序的入口点。
//#include "stdafx.h"
#include "l4jlog.h"int main()
{{LOG_TRACE("this is trace message.");LOG_DEBUG("this is debug message.");LOG_INFO("this is info message.");LOG_WARN("this is warn message.");LOG_ERROR("this is error message.");LOG_FATAL("this is fatal message.");LOG_DEBUG("hello, %s, timestamp:%ld", "this is debug message.", time(0));}system("pause");return 0;
}

3、日志配置文件

log4cplus.rootLogger=TRACE, STDOUT, RootAppenderlog4cplus.appender.STDOUT=log4cplus::ConsoleAppender
log4cplus.appender.STDOUT.layout=log4cplus::PatternLayout
log4cplus.appender.STDOUT.layout.ConversionPattern=%D{%Y/%m/%d %H:%M:%S.%q} [%t] [%-5p] %c{2} [%l][%M] - %m%nlog4cplus.appender.RootAppender=log4cplus::RollingFileAppender
log4cplus.appender.RootAppender.File=logs/ConsoleApplicationDemo.log
log4cplus.appender.RootAppender.CreateDirs=true
log4cplus.appender.RootAppender.MaxFileSize=1MB
log4cplus.appender.RootAppender.MaxBackupIndex=10
log4cplus.appender.RootAppender.layout=log4cplus::PatternLayout
log4cplus.appender.RootAppender.layout.ConversionPattern=%D{%Y/%m/%d %H:%M:%S.%q} [%t] [%-5p] %c{2} [%l][%M] - %m%n

4、日志输出
