错误的Boost Log时间戳格式

我正在使用Boost 1.54 Log并按以下方式初始化我的日志记录:

namespace logging = boost::log;
namespace src = boost::log::sources;
namespace expr = boost::log::expressions;
namespace sinks = boost::log::sinks;
namespace attrs = boost::log::attributes;
namespace keywords = boost::log::keywords;

BOOST_LOG_ATTRIBUTE_KEYWORD(line_id, "LineID", unsigned int)
BOOST_LOG_ATTRIBUTE_KEYWORD(severity, "Severity", severity_level)
BOOST_LOG_ATTRIBUTE_KEYWORD(tag_attr, "Tag", std::string)
BOOST_LOG_ATTRIBUTE_KEYWORD(timestamp, "TimeStamp", boost::posix_time::ptime)

logging::add_common_attributes();
boost::shared_ptr<logging::core> core = logging::core::get();

// setup console log
logging::add_console_log (
    std::clog,
    keywords::filter = severity >= debug,
    keywords::format = (
        expr::stream << expr::format_date_time(timestamp, "%Y-%m-%d %H:%M:%S") <<
            line_id << " [" << severity << "] " << expr::smessage
    )
);

这是生成的输出的示例:

2013-09-13 10:17:471 [warn] You are running in debug mode - assertions are enabled.
2013-09-13 10:17:472 [info] loading data completed

时间戳的输出秒数完全不正确,但根据Boost日志文档%S是秒的正确格式设置。这会是一个错误吗?

2 个答案:

答案 0 :(得分:8)

时间和line_id之间没有空格,因此它们一起运行。

否则,请通过以下代码替换关键字:: format:
