Cpp調用Log4cpp生成日志

初始化代碼:

log4cpp::PatternLayout* pLayout = new log4cpp::PatternLayout();
  pLayout->setConversionPattern("%d: %p %c %x: %m%n");

  log4cpp::Appender* fileAppender = new log4cpp::FileAppender("fileAppender","日志.log");
  fileAppender->setLayout(pLayout);

  log4cpp::Category& root = log4cpp::Category::getRoot().getInstance("日志類型");
  root.addAppender(fileAppender);
  root.setPriority(log4cpp::Priority::DEBUG);
