如何从START_OBJECT令牌中反序列化java.lang.String实例

ObjectMapper objectMapper = new ObjectMapper();

JsonNode jsonNode = objectMapper.readTree(jsonData);

JsonNode valueNode = jsonNode.get("propertyName");

String value = valueNode.asText();

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonDeserializer {
    public static void main(String[] args) {
        String jsonData = "{\"propertyName\":\"propertyValue\"}";

        try {
            ObjectMapper objectMapper = new ObjectMapper();
            JsonNode jsonNode = objectMapper.readTree(jsonData);
            JsonNode valueNode = jsonNode.get("propertyName");
            String value = valueNode.asText();

            System.out.println(value);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
