Question

我可以找到log4j的解决方案，但不能找到log4cxx。

Answer 1

我得到了一个简单的解决方案。

extern LoggerPtr logger;

#define LOG_TRACE(msg) LOG4CXX_TRACE(logger, msg)
#define LOG_DEBUG(msg) LOG4CXX_DEBUG(logger, msg)
#define LOG_INFO(msg) LOG4CXX_INFO(logger, msg)
#define LOG_INFO_H(msg) LOG4CXX_INFO(logger, "\33[0;42m" << msg << "\33[0m") // green
#define LOG_WARN(msg) LOG4CXX_WARN(logger, "\33[0;43m" << msg << "\33[0m") // yellow
#define LOG_ERROR(msg) LOG4CXX_ERROR(logger, "\33[0;41m" << msg << "\33[0m") // red
#define LOG_FATAL(msg) LOG4CXX_FATAL(logger, "\33[0;41m" << msg << "\33[0m") // red

Answer 2

谷歌把我带到这里，我发布我的解决方案，跳过它可以帮助别人。

我实现了针对log4j找到的c ++ this解决方案，创建了一个继承自Layout的{{1}}类。它只是将标准PatternLayout的输出包装在颜色转义序列中。

我将以下内容放在cpp文件中（如果您愿意，可以将其拆分为hpp / cpp）：

log4cxx::PatternLayout

当然，配置你的记录器使用这个布局类，并像使用PatterLayout一样使用它，例如在#include <log4cxx/helpers/pool.h> #include <log4cxx/patternlayout.h> namespace log4cxx{ class LOG4CXX_EXPORT ColorPatternLayout : public log4cxx::PatternLayout { public: DECLARE_LOG4CXX_OBJECT(ColorPatternLayout) BEGIN_LOG4CXX_CAST_MAP() LOG4CXX_CAST_ENTRY(ColorPatternLayout) LOG4CXX_CAST_ENTRY_CHAIN(Layout) END_LOG4CXX_CAST_MAP() ColorPatternLayout(); ColorPatternLayout(const log4cxx::LogString &s); virtual void format(log4cxx::LogString &output, const log4cxx::spi::LoggingEventPtr &event, log4cxx::helpers::Pool &pool) const override; }; LOG4CXX_PTR_DEF(ColorPatternLayout); } using namespace log4cxx; IMPLEMENT_LOG4CXX_OBJECT(ColorPatternLayout); ColorPatternLayout::ColorPatternLayout() : log4cxx::PatternLayout(){} ColorPatternLayout::ColorPatternLayout(const LogString &s): log4cxx::PatternLayout(s){} void ColorPatternLayout::format(LogString &output, const spi::LoggingEventPtr &event, helpers::Pool &pool) const { log4cxx::LogString tmp; log4cxx::PatternLayout::format(tmp,event,pool); log4cxx::LevelPtr lvl = event->getLevel(); switch (lvl->toInt()){ case log4cxx::Level::FATAL_INT: output.append("\u001b[0;41m"); //red BG break; case log4cxx::Level::ERROR_INT: output.append("\u001b[0;31m"); // red FG break; case log4cxx::Level::WARN_INT: output.append("\u001b[0;33m"); //Yellow FG break; case log4cxx::Level::INFO_INT: output.append("\u001b[1m"); // Bright break; case log4cxx::Level::DEBUG_INT: output.append("\u001b[2;32m"); // Green FG break; case log4cxx::Level::TRACE_INT: output.append("\u001b[0;30m"); // Black FG break; default: break; } output.append(tmp); output.append("\u001b[m"); }文件中：

log4cxx.properties

如何设置log4cxx控制台输出的颜色？
