在使用Kotlin在Micronaut中与Jackson进行序列化时，如何保持精度？

Question

我正在尝试使用Micronaut和Kotlin序列化以下数据类

数据类Item（val name：String，val price：Double）

输出应为

import UIKit
import AVKit
import AVFoundation

class ViewController: UIViewController {

    @IBOutlet weak var powerLVLlabel: UILabel!

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.

    }

    func playVideo() {
        guard let path = Bundle.main.path(forResource: "over 9000", ofType:"mp4") else {
            debugPrint("over 9000.mp4 not found")
            return
        }
        let player = AVPlayer(url: URL(fileURLWithPath: path))
        let playerController = AVPlayerViewController()
        playerController.player = player
        present(playerController, animated: true)
        player.play()

    }

    @IBAction func randomNumber(_ sender: Any) {

        let randomNumber = Int.random(in: 1000...10000)
        powerLVLlabel.text = String(randomNumber)
        if randomNumber >= 9000 {
            playVideo()
        }

    }
}

它从Json响应中删除了结尾的零
