封装的最后结果像下面这样:

主要封装的功能,提供日志等级、日志文件大小设置,滚动写多个文件,文件个数可设置,提供日志服务器(用了Windows的CreateThread,如果在其他环境下用对应的线程工具即可)

#include "robotlog.h"

int main()
{
	//ROBOTLOG_API RobotLog(
	//	const wstring& file_name = L"..\\log\\robot.log",
	//	const wstring&  number_of_file = L"10",
	//	const wstring&  size_of_log_file = L"8388608",//一个文件8MB
	//	const wstring&  log_level = L"0",
	//	const wstring& ip = L"localhost",
	//	const wstring&  port = L"20009"
	//	);


	RobotLog* logger = new RobotLog(L".\\robot.txt",L"3",L"8388608",L"0",L"172.16.107.197",L"20009");
	cout<<"main write log"<<endl;
	//for (int i=0;i<10;i++)
	//{
		logger->write_debug("hello 1 debug");
	//	logger->write_error("hello 2 error");
	//	logger->write_infor("hello 4 infor");
	//	logger->write_trace("hello 5 trace");
	//}
	cout<<"server listenning...."<<endl;
	RobotServerLogThread* thrd = new RobotServerLogThread(L"20009");
	thrd->run_log_server();

	cout<<"after run log server"<<endl;
}

输出日志:

说明:从构造函数为L"something"来看,项目使用了Unicode编码,这个要在VS里面设置一下。


实现:

(1)由于这里封装成了dll,所以你的项目属性应该在预编译Preprocessor里面加上ROBOTLOG_EXPORTS

(2)这里使用了log4cplus的静态库作为功能支持,所以在项目的Input里面应该加上log4cplusS.lib,这里加的是log4cplus的Release版本,如果你需要Debug版本,请编译对应的版本,把生成的log4cplusSD.lib加入到你的项目里面。

(3)log4cplus的工程下载,编译生成动态或静态链接库:点击打开链接

(4)log4cplus的工程下载,也可以下载我提交的一个不是最新版的版本:点击打开链接,用VS有几个地方要注意,编码格式,生成动态库的格式,依赖库的格式,等自己要知道。
