Zap Logger 的日志级别可以在运行时动态更改吗？

import (
    "go.uber.org/zap"
    "go.uber.org/zap/zapcore"
    "os"
)

func main() {
    // Set the underlying level to the default (DebugLevel)
    atom := zap.NewAtomicLevel()

    // Disable timestamps for deterministic logging
    encoderCfg := zap.NewProductionEncoderConfig()
    encoderCfg.TimeKey = ""

    // Create a logger with a JSON encoder and the atomic level
    logger := zap.New(zapcore.NewCore(
        zapcore.NewJSONEncoder(encoderCfg),
        zapcore.Lock(os.Stdout),
        atom,
    ))

    // Clean up resources when the program exits
    defer logger.Sync()

    // Log at the default level (DebugLevel)
    logger.Info("info logging enabled")

    // Change the atomic level to ErrorLevel
    atom.SetLevel(zapcore.ErrorLevel)

    // Log again, but at the new level (ErrorLevel)
    logger.Info("info logging disabled")
}
