log4cxx 使用

调用log4cxx步骤

1. 引入头文件和lib

#include <log4cxx/logger.h>
#include <log4cxx/propertyconfigurator.h>

#pragma comment (lib, "log4cxx.lib") 或者 把log4cxx.lib 加到 project->settings->linker->object/library modules

2. 设置配置文件

log4cxx::PropertyConfigurator::configureAndWatch

3. 写log

log4cxx::Logger::getLogger(_pref)->info

log4cxx::Logger::getLogger(_pref)->debug

log4cxx::Logger::getLogger(_pref)->fatal

...

log4cxx支持对不同的prefix 使用不同的appender,比如像下面的.properties 文件

# DEBUG < INFO < WARN < ERROR < FATAL
log4j.rootLogger=info, R
log4j.logger.TNetSvr = info, TNS
log4j.logger.TNetCmd = info, TNC
log4j.logger.TMQSvr = info, TMQ
