在java中创建基于逗号分隔字符串的json？

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>

    <version>2.12.4</version>
</dependency>

public class MyJson {
    private List<String> values;

    public List<String> getValues() {
        return values;
    }

    public void setValues(List<String> values) {
        this.values = values;
    }
}

import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    public static void main(String[] args) throws Exception {
        MyJson myJson = new MyJson();
        List<String> values = Arrays.asList("value1", "value2", "value3");
        myJson.setValues(values);

        ObjectMapper objectMapper = new ObjectMapper();
        String jsonString = objectMapper.writeValueAsString(myJson);

        System.out.println(jsonString);
    }
}

{"values":["value1","value2","value3"]}
