基于spdlog开源库封装的日志类

功能

提供了3种不同的日志模式

• 控制台模式(mode = 1)，打印结果输出到控制台
• 文件模式(mode = 2)，打印结果输出到指定文件中
• 控制台+文件模式(mode = 3)，打印结果输出到控制台和指定文件中

五种打印级别

ZLOG_TRACE(); 
ZLOG_DEBUG();
ZLOG_INFO();
ZLOG_WARN(); 
ZLOG_ERROR

使用

编译安装spdlog后，直接包含该头文件即可 #include "logging.h"

在使用的过程中，记得加上-lspdlog编译链接参数

示例代码：

#include "logging.h"

int main() {

    ZLOG::getInstance("./log/", "test.log", 3);

	int param = 1;
 
	ZLOG_TRACE("this is trace log record, param: {}", ++param); // int type param is ok
	ZLOG_DEBUG("this is debug log record, param: {}", ++param);
	ZLOG_INFO("this is info log record, param: {}", ++param);
	ZLOG_WARN("this is warn log record, param: {}", double(++param)); // double type param is ok
	ZLOG_ERROR("this is error log record, param: {}", std::to_string(++param)); // string type param is ok
 
	return 0;

}

编译运行：

g++ -g main.cpp -o main -lspdlog 
./main

运行结果：
