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添加到我项目的类路径中

我创建了以下Main课程:

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);

  } …
