SLF4J-简单属性文件部分起作用

Question

当仅放置在simplelogger.properties文件中的某些属性起作用时，我遇到了一个问题。这是文件内容：

#include <cstddef>
#include <functional>
#include <experimental/type_traits>
#include <utility>

enum class FunctionFlags

    none            = 0,
    comparable_less = 0b1,
    comparable_eq   = 0b10,
    hashable        = 0b100,
};
constexpr FunctionFlags operator|(FunctionFlags a, FunctionFlags b) {return FunctionFlags(int(a) | int(b));}
constexpr FunctionFlags operator&(FunctionFlags a, FunctionFlags b) {return FunctionFlags(int(a) & int(b));}
