基于spdlog的Logger类封装

简介

使用

使用export LOG_LEVEL=n控制日志级别

日志级别

• TRACE: export LOG_LEVEL=0

• DEBUG: export LOG_LEVEL=1

• INFO： export LOG_LEVEL=2

• ERROR：export LOG_LEVEL=3

• OFF： export LOG_LEVEL=5

printf风格打印

 LOG_TRACE("This is a Trace message");
 LOG_DEBUG("This is a Debug message");
 LOG_INFO("This is an Info message");
 LOG_WARN("This is a Warning message");
 LOG_ERROR("This is an Error message");

std::cout风格打印

LOG(TRACE) << "This is a Trace message";
LOG(DEBUG) << "This is a Debug message";
LOG(INFO) << "This is an Info message";
LOG(WARN) << "This is a Warning message";
LOG(ERROR) << "This is an Error message";

自定义Log宏

• HEADER(LEVEL): 用于控制后续日志的缩进，方便观察调用栈

• FOOTER(LEVEL)：与HEADER配对使用

void func2() {
    HEADER(DEBUG);
    FOOTER(DEBUG);
}
