log4cplus使用

log4cplus is a simple to use C++ logging API providing thread-safe, flexible, and arbitrarily granular control over log management and configuration. It is modelled after the Java log4j API. 下载地址[http://sourceforge.net/projects/log4cplus/][http_sourceforge.net_projects_log4cplus]

也可以看出Java/C++是互相借鉴的，没有好坏之分。

很详细的介绍在 [log4cplus学习笔记（一）][log4cplus]

还有一篇学习笔记，可以参考下 [log4cplus使用指南][log4cplus 1]

本文记录在项目中的一个常用实例。

定义工具文件

Util.h

<span style="font-family:KaiTi_GB2312;font-size:14px;">#include <log4cplus/logger.h>  
    #include <log4cplus/configurator.h>  
    #include <log4cplus/fileappender.h>  
    #include <log4cplus/loggingmacros.h>  
    using namespace log4cplus;  
    using namespace log4cplus::helpers;  
    inline void InitLogger(  
      const string& name = "PINGLOG",  
      const string& path = "./log",  
      const string& loglevel = "DEBUG",  
      const string& pattern = "%-10D{%H:%M:%S.%q} : [%p] : %m%n")  
    {  
      log4cplus::SharedAppenderPtr append_1(new log4cplus::DailyRollingFileAppender(path, log4cplus::HOURLY , 1, true));  
      append_1->setName(name);  
      append_1->setLayout( std::auto_ptr<log4cplus::Layout>(new log4cplus::PatternLayout(pattern)) );  
      log4cplus::Logger::getInstance(name).addAppender(append_1);  
      log4cplus::Logger::getInstance(name).setLogLevel(log4cplus::LogLevelManager().fromString(loglevel));  
    }  
      
    #define LOG_DEBUG(msg) \  
      LOG4CPLUS_DEBUG(log4cplus::Logger::getInstance("PINGLOG"), msg)  
    #define LOG_INFO(msg) \  
      LOG4CPLUS_INFO(log4cplus::Logger::getInstance("PINGLOG"), msg)   
    #define LOG_WARN(msg) \  
      LOG4CPLUS_WARN(log4cplus::Logger::getInstance("PINGLOG"), msg)  </span>

使用

<span style="font-family:KaiTi_GB2312;font-size:14px;">#include "Util.h"  
    InitLogger();  
    LOG_INFO("test");  
    LOG_WARN("test" << " WARN"); </span>
