log4cplus例子

使用log4cplus 1.2.0版本，C++98 标准下编译可用

#include <log4cplus/logger.h>
#include <log4cplus/consoleappender.h>
#include <log4cplus/fileappender.h>
#include <log4cplus/loggingmacros.h>

 
#include <unistd.h>
using namespace log4cplus;

using namespace log4cplus::helpers;

 

int main()
{
    /* step 1: Instantiate an appender object */

    //SharedObjectPtr<Appender> _append (new ConsoleAppender());
    SharedAppenderPtr _append(new RollingFileAppender("Test.log", 5*1024, 5));
    _append->setName("append for  test");

    /* step 2: Instantiate a layout object */

    std::string pattern = "%d{%m/%d/%y  %H:%M:%S}  - %m [%l]%n";

    std::auto_ptr<Layout> _layout(new PatternLayout(pattern));


    /* step 3: Attach the layout object to the appender */

    _append->setLayout( _layout );


    /* step 4:  Instantiate a logger object */

    Logger _logger = Logger::getInstance("test");


    /* step 5: Attach the appender object to the  logger  */

    _logger.addAppender(_append);


    /* step 6: Set a priority for the logger  */

    _logger.setLogLevel(ALL_LOG_LEVEL);


    /* log activity */
for(int i = 0; i < 100000; i++ ){
    LOG4CPLUS_DEBUG(_logger, "This is the  FIRST log message...");


    LOG4CPLUS_WARN(_logger, "This is the  SECOND log message...");
}
    return 0;
