在主线程中发生异常"main"java.lang.NoSuchMethodError：com.fasterxml.jackson.core.JsonFactory.requiresPropertyOrdering()Z

我需要将json转换为pojo。我决定使用jackson，并将jackson-core-2.2.0.jar、jackson-databind-2.4.4.jar和jackson-annotations-2.1.2.jar添加到我的项目的类路径中。

我创建了以下Main类：

import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.List;
import com.fasterxml.jackson.core.JsonGenerationException;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonMappingException;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.core.JsonGenerationException;
import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.JsonMappingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.DeserializationFeature;
public class Json {
    private static String SRC= "";
    public static void main(String[] args) {
        AwardList awardList = null;
        ObjectMapper mapper = new ObjectMapper();
        try {
            awardList = (AwardList) mapper.readValue(new URL(SRC), AwardList.class);
        } catch (JsonGenerationException e) {
            e.printStackTrace();
        } catch (JsonMappingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println(awardList);
    }
}

以及以下AwardList类：

public class AwardList {
    private Flights[] flights;
    private String[] connections;
    private SaverEconomy saverEconomy;
    private StandartEconomy standartEconomy;
    private SaverBusiness saverBusiness;
    private StandartFirst standartFirst;
    private SaverFirst saverFirst;
    
    public Flights[] getFlights() {
        return flights;
    }
    
    public void setFlights(Flights[] flights) {
        this.flights = flights;
    }
    
    public SaverEconomy getSaverEconomy() {
        return saverEconomy;
    }
    
    public void setSaverEconomy(SaverEconomy saverEconomy) {
        this.saverEconomy = saverEconomy;
    }
    
    public StandartEconomy getStandartEconomy() {
        return standartEconomy;
    }
    
    public void setStandartEconomy(StandartEconomy standartEconomy) {
        this.standartEconomy = standartEconomy;
    }
    
    public SaverBusiness getSaverBusiness() {
        return saverBusiness;
    }
    
    public void setSaverBusiness(SaverBusiness saverBusiness) {
        this.saverBusiness = saverBusiness;
    }
    
    public StandartFirst getStandartFirst() {
        return standartFirst;
    }
    
    public void setStandartFirst(StandartFirst standartFirst) {
        this.standartFirst = standartFirst;
    }
    
    public SaverFirst getSaverFirst() {
        return saverFirst;
    }
    
    public void setSaverFirst(SaverFirst saverFirst) {
        this.saverFirst = saverFirst;
    }
    
    public String[] getConnections() {
        return connections;
    }
    
    public void setConnections(String[] connections) {
        this.connections = connections;
    }
}

我想将json转换为pojo并将其保存在数据库中。但是我一直遇到以下错误：

Exception in thread "main" java.lang.NoSuchMethodError: com.fasterxml.jackson.core.JsonFactory.requiresPropertyOrdering()Z
  at com.fasterxml.jackson.databind.ObjectMapper.(ObjectMapper.java:457)
  at com.fasterxml.jackson.databind.ObjectMapper.(ObjectMapper.java:379)
  at Json.main(Json.java:72)
