SnakeYAML-如何使用特定变量名转储YAML文件

我有一个POJO，看起来像这样：

public class Foo {
    private String barA;
    private String barB;

    public void setBarA(String barA) {
        this.barA = barA;
    }

    public void setBarB(String barB) {
        this.barB = barB;
    }

    public String getBarA() {
        return barA;
    }

    public String getBarB() {
        return barB;
    }
}

Representer representer = new Representer();
representer.addClassTag(Foo.class, tag.MAP);
DumperOptions options = new DumperOptions();
options.setDefaultFlowStyle(DumperOptions.FlowStyle.BLOCK);
Yaml yaml = new Yaml(representer, options);
StringWriter writer = new StringWriter();
yaml.dump(foo, writer);

barA
barB

bar_a
bar_b

我将其转换为YAML的代码如下所示：

public class Foo {
    private String barA;
    private String barB;

    public void setBarA(String barA) {
        this.barA = barA;
    }

    public void setBarB(String barB) {
        this.barB = barB;
    }

    public String getBarA() {
        return barA;
    }

    public String getBarB() {
        return barB;
    }
}

Representer representer = new Representer();
representer.addClassTag(Foo.class, tag.MAP);
DumperOptions options = new DumperOptions();
options.setDefaultFlowStyle(DumperOptions.FlowStyle.BLOCK);
Yaml yaml = new Yaml(representer, options);
StringWriter writer = new StringWriter();
yaml.dump(foo, writer);

barA
barB

bar_a
bar_b

使用SnakeYAML的输出如下所示：

public class Foo {
    private String barA;
    private String barB;

    public void setBarA(String barA) {
        this.barA = barA;
    }

    public void setBarB(String barB) {
        this.barB = barB;
    }

    public String getBarA() {
        return barA;
    }

    public String getBarB() {
        return barB;
    }
}

Representer representer = new Representer();
representer.addClassTag(Foo.class, tag.MAP);
DumperOptions options = new DumperOptions();
options.setDefaultFlowStyle(DumperOptions.FlowStyle.BLOCK);
Yaml yaml = new Yaml(representer, options);
StringWriter writer = new StringWriter();
yaml.dump(foo, writer);

barA
barB

bar_a
bar_b

但是，在输出中，我希望变量的命名约定如下所示：

public class Foo {
    private String barA;
    private String barB;

    public void setBarA(String barA) {
        this.barA = barA;
    }

    public void setBarB(String barB) {
        this.barB = barB;
    }

    public String getBarA() {
        return barA;
    }

    public String getBarB() {
        return barB;
    }
}

Representer representer = new Representer();
representer.addClassTag(Foo.class, tag.MAP);
DumperOptions options = new DumperOptions();
options.setDefaultFlowStyle(DumperOptions.FlowStyle.BLOCK);
Yaml yaml = new Yaml(representer, options);
StringWriter writer = new StringWriter();
yaml.dump(foo, writer);

barA
barB

bar_a
bar_b

我如何使用SnakeYAML实现这一点？我想澄清一下，我不想更改Java变量的命名约定。我相信这可能是使用

TypeDescription

或某种序列化实现的，但我不确定具体如何实现这一点。

正如我在回答另一个问题时提到的，由于以下原因，目前不可能实现。
