执行每个日志代码行后,我需要提升记录。是否有可能以某种方式配置接收器以这种方式行事?目前日志在程序结束后填写。
#include <boost/log/core.hpp>
#include <boost/log/trivial.hpp>
#include <boost/log/expressions.hpp>
#include <boost/log/sinks/text_file_backend.hpp>
#include <boost/log/utility/setup/file.hpp>
#include <boost/log/utility/setup/common_attributes.hpp>
#include <boost/log/sources/severity_logger.hpp>
#include <boost/log/sources/record_ostream.hpp>
#include <conio.h>;
namespace logging = boost::log;
namespace src = boost::log::sources;
namespace sinks = boost::log::sinks;
namespace keywords = boost::log::keywords;
void init()
{
logging::add_file_log
(
keywords::file_name = "sample_%N.log", /*< file name pattern >*/
keywords::rotation_size = 10 * 1024 * 1024, /*< rotate files every 10 MiB... >*/
keywords::time_based_rotation = sinks::file::rotation_at_time_point(0, 0, 0), /*< ...or at midnight >*/
keywords::format = "[%TimeStamp%]: %Message%" /*< log record format >*/
);
logging::core::get()->set_filter
(
logging::trivial::severity >= logging::trivial::info
);
logging::core::get();
}
//]
#endif
int main(int, char*[])
{
init();
logging::add_common_attributes();
using namespace logging::trivial;
src::severity_logger< severity_level > lg;
BOOST_LOG_SEV(lg, trace) << "A trace severity message";
BOOST_LOG_SEV(lg, debug) << "A debug severity message";
BOOST_LOG_SEV(lg, info) << "An informational severity message";
BOOST_LOG_SEV(lg, warning) << "A warning severity message";
BOOST_LOG_SEV(lg, error) << "An error severity message";
BOOST_LOG_SEV(lg, fatal) << "A fatal severity message";
std::cin.get();
return 0;
}
答案 0 :(得分:8)
正如评论者所说,只需添加 auto_flush
关键字:
logging::add_file_log
(
keywords::file_name = "sample_%N.log", /* file name pattern */
keywords::rotation_size = 10 * 1024 * 1024, /* rotate files every 10 MiB... */
keywords::time_based_rotation = sinks::file::rotation_at_time_point(0, 0, 0), /* ...or at midnight */
keywords::auto_flush = true,
keywords::format = "[%TimeStamp%]: %Message%" /* log record format */
);
