log4cpp 封装

最近学习log4cpp，试着封装了下，mark下。

#include<iostream> #include<log4cpp/Category.hh> #include<log4cpp/Appender.hh> #include<log4cpp/FileAppender.hh> #include<log4cpp/RollingFileAppender.hh> #include<log4cpp/OstreamAppender.hh> #include<log4cpp/PatternLayout.hh> #include<log4cpp/Priority.hh> using namespace std; //1.实现日志文件信息在终端上显示 //2.实现日志文件信息在终端和日志文件同时显示 //3.实现回滚备份，替换掉2即可 class Mylog { public: Mylog(); ~Mylog(); public: void error(const char * msg); void warn(const char * msg); void info(const char * msg); void debug(const char * msg); void set_priority(const char *); private: //布局 log4cpp::PatternLayout * pLayout_cout_; log4cpp::PatternLayout * pLayout_file_; log4cpp::PatternLayout * pLayout_rollfile_; //依附目标文件 log4cpp::OstreamAppender * osAppender_; log4cpp::FileAppender * fileAppender_; log4cpp::RollingFileAppender * rollfileAppender_; //种类 log4cpp::Category & root_; }; //构造函数 //引用必须用初始化列表初始化 Mylog::Mylog():root_(log4cpp::Category::getInstance("infoCategory")) { std::cout << "Mylog()" << std::endl; //创建Layout并设置成pattern模式 pLayout_cout_ = new log4cpp::PatternLayout(); pLayout_cout_ -> setConversionPattern("%d: %p %c %x: %m%n"); pLayout_file_ = new log4cpp::PatternLayout(); pLayout_file_ -> setConversionPattern("%d: %p %c %x: %m%n"); pLayout_rollfile_ = new log4cpp::PatternLayout(); pLayout_rollfile_ -> setConversionPattern("%d: %p %c %x: %m%n"); //创建Appender并将layout对象绑定 osAppender_ = new log4cpp::OstreamAppender("osAppender_", &std::cout); osAppender_ -> setLayout(pLayout_cout_); //日志文件保存在固定的文件夹中 fileAppender_ = new log4cpp::FileAppender("fileAppender_", "/home/lukey/log/myfile_log"); fileAppender_ -> setLayout(pLayout_file_); //回滚文件也是保存在固定地方，为了便于测试把文件大小设置成1*1024 rollfileAppender_ = new log4cpp::RollingFileAppender("rollfileAppender_","/home/lukey/log/myrolfile_log", 1*1024, 3); rollfileAppender_ -> setLayout(pLayout_rollfile_); //log4cpp::Category & root_ = log4cpp::Category::getInstance("infoCategory");//不能再这初始化，引用必须在初始化列表中 //把Appender对象附到category上,一个category可以有多个appender root_.addAppender(osAppender_); root_.addAppender(fileAppender_); root_.addAppender(rollfileAppender_); } //设置优先级 void Mylog::set_priority(const char * prioritylevel) { if(prioritylevel == "DEBUG") root_.setPriority(log4cpp::Priority::DEBUG); else if(prioritylevel == "ERROR") root_.setPriority(log4cpp::Priority::ERROR); else if(prioritylevel == "WARN") root_.setPriority(log4cpp::Priority::WARN); else if(prioritylevel == "INFO") root_.setPriority(log4cpp::Priority::INFO); else //把优先级设置到最低 root_.setPriority(801); } void Mylog::error(const char * msg) { std::cout << "error()" << std::endl; root_.error(msg); } void Mylog::warn(const char * msg) { std::cout << "warn()" << std::endl; root_.warn(msg); } void Mylog::info(const char * msg) { std::cout << "info()" << std::endl; root_.info(msg); } void Mylog::debug(const char * msg) { std::cout << "debug()" << std::endl; root_.debug(msg); } //析构函数 Mylog::~Mylog() { std::cout << "~Mylog()" << std::endl; log4cpp::Category::shutdown(); } //简单测试所写的封装 int main(int argc, char * argv[]) { const char * msg = "hello,world"; const char * priority = "ERROR"; Mylog mylog; mylog.set_priority(priority); mylog.error(msg); mylog.warn(msg); mylog.info(msg); mylog.debug(msg); return 0; }
