Question

我想加载这个文件（test.yml）：

Car1:
    countriesSold: [Spain, France, Italy]
    model: Seat
    specs: {color: black, height: 29, with: 29}
Car2:
    countriesSold: [Germany, France]
    model: BMW
    specs: {color: white, height: 11, with: 33}

致Map<String, Car>。

我在SnaleYAML中看到的所有示例都始终将Map对象放在另一个对象中。

当我尝试像这样加载我的文件时

Map<String, Car> load = 
(Map<String, Car>) yaml.load(new ClassPathResource("test.yml").getInputStream());

它被加载到Map的Map中，里面的所有内容都是字符串。

我想我需要提供Constructor内部类型的TypeDescription个对象和Yaml个对象TypeDescription mapDesc = new TypeDescription(Map.class); mapDesc.putMapPropertyType("???", String.class, Car.class); Constructor constructor = new Constructor(mapDesc);，但我不知道该怎么做。像这样的东西，但是我不确定要为根元素放什么，这就是Map：

public class Car {

    private String model;
    private Specs specs;
    private List<String> countriesSold = new ArrayList<>();

    public String getModel() {
        return model;
    }

    public void setModel(String model) {
        this.model = model;
    }

    public Specs getSpecs() {
        return specs;
    }

    public void setSpecs(Specs specs) {
        this.specs = specs;
    }

    public List<String> getCountriesSold() {
        return countriesSold;
    }

    public void setCountriesSold(List<String> countriesSold) {
        this.countriesSold = countriesSold;
    }
}

Car类看起来像这样：

public class Specs {

    private int height;
    private int with;

    public int getHeight() {
        return height;
    }

    public void setHeight(int height) {
        this.height = height;
    }

    public int getWith() {
        return with;
    }

    public void setWith(int with) {
        this.with = with;
    }
}

Specs类看起来像这样：

如何使用SnakeYAML将yaml直接加载到Map <string，car =“”>？</string，>
