Jackson - 使用动态密钥反序列化 json

Java
import com.fasterXML.jackson.databind.JSonNode;
import com.fasterXML.jackson.databind.ObjectMapper;
public class DynamicKeyDeserializeExample {
    public static void mAIn(String[] args) {
        String JSon = "{\"key1\": \"value1\", \"key2\": \"value2\", \"key3\": \"value3\"}";
        try {
            ObjectMapper objectMapper = new ObjectMapper();
            JSonNode JSonNode = objectMapper.readTree(JSon);
            // 遍历 JSON 数据的键，并获取对应的值
            JSonNode.fieldNames().forEachRemAIning(key -> {
                JSonNode valueNode = JSonNode.get(key);
                String value = valueNode.asText();
                System.out.println("Key: " + key + ", Value: " + value);
            });
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
