1. 写一个头文件,"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__)


2. 在所有要打log的cpp文件里 include "mylog.h",
并在文件的最前面加一句: USE_SEPARATE_LOG(__FILE__)

3. 所有打log的地方都用下面的句子打:
LOG4CPLUS_INFO(fLog, "testtest"<<endl);

比如:

#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;
}
还是想说,按源代码文件分log文件的办法真的不是个好办法.
