1. 寫一個頭檔案,"mylog.h",如下:

#pragma once
#include <log4cplus/logger.h>
#include <log4cplus/configurator.h>
#include <log4cplus/fileappender.h>
#include <log4cplus/consoleappender.h>
#include <log4cplus/layout.h>
#include <log4cplus/logger.h>
#include <log4cplus/ndc.h>
#include <log4cplus/helpers/loglog.h>
#include <log4cplus/helpers/threads.h>
#include <log4cplus/streams.h>
using namespace std;
using namespace log4cplus;

struct GLOG
{
    GLOG(const char  * _fname)
    { 
        string n = _fname; 
        Logger _l = (Logger::getInstance(n));
        n+= ".log";
        _l.addAppender(new RollingFileAppender(n.c_str(), 1024*10, 10));
        _l.addAppender(new  ConsoleAppender()); 
    }
};
 
#define USE_SEPARATE_LOG(fname)  static GLOG _g(fname);

#define fLog                     Logger::getInstance(__FILE__)
 

   LOG4CPLUS_INFO(fLog, "testtest"<<endl);

#include "stdafx.h"
#include <iostream>
#include "mylog.h"
 
USE_SEPARATE_LOG(__FILE__)

int main(int argc, _TCHAR* argv[])
{
     LOG4CPLUS_INFO(fLog, "Hello world"<<endl);
     return 0;
}
 

BTW：每個檔案記錄一個日誌檔案真不是什麼好辦法。
