Parse string array using snakeYaml

Question

I have a yaml file in this way

A: ["aa","bb","cc"]

I wonder is there any YAML library can parse this string array rather than using string library?

Answer 1

You can use snakeyaml like this:

define library in your pom.xml:

<dependency>
    <groupId>org.yaml</groupId>
    <artifactId>snakeyaml</artifactId>
    <version>1.23</version>
</dependency>

Mapper class:

public class YamlEntity {
    private Map<String, List<String>> value;

    public Map<String, List<String>> getValue() {
        return value;
    }

    public void setValue(Map<String, List<String>> value) {
        this.value = value;
    }

    @Override
    public String toString() {
        return "YamlEntity [value=" + value + "]";
    }

 }

yaml file like example.yaml

value: [aa, bb, cc]

and your method:

public static void readYaml() {
    Yaml yaml = new Yaml();
    InputStream is = App.class.getResourceAsStream("example.yaml");

    Map<String, List<YamlEntity>> ye = yaml.load(is);
    System.out.println(ye.get("value"));
}

result is: [aa, bb, cc]
