将带有属性的Java Enum序列化为json对象

public enum Color {
    RED("#FF0000"),
    GREEN("#00FF00"),
    BLUE("#0000FF");

    private String rgbValue;

    Color(String rgbValue) {
        this.rgbValue = rgbValue;
    }

    public String getRgbValue() {
        return rgbValue;
    }
}

import com.fasterxml.jackson.databind.ObjectMapper;

public class EnumSerializationExample {
    public static void main(String[] args) throws Exception {
        ObjectMapper objectMapper = new ObjectMapper();
        Color color = Color.RED;

        // 将Enum对象序列化为json字符串
        String json = objectMapper.writeValueAsString(color);
        System.out.println(json);

        // 将json字符串反序列化为Enum对象
        Color deserializedColor = objectMapper.readValue(json, Color.class);
        System.out.println(deserializedColor);
    }
}
