log4cplus简单封装
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。
