Spring Boot 从静态json文件中读取数据所需字段

import org.springframework.beans.factory.annotation.Value;
import org.springframework.core.io.Resource;
@Value("classpath:static/data/area.json")
private Resource areaRes;

@Override
  public void test(){
  for (int i = 1; i < 8; i ++) {
   try {
     String areaData = IOUtils.toString(areaRes.getInputStream(), Charset.forName("UTF-8"));
     List<String> districtNames = JsonPath.read(areaData, "$.districts[?(@.id == " + i + ")].name");
     String district = districtNames.get(0);
     System.out.println("数字"+ i+ "表示的行政区为：" + district);
   }catch (IOException e){
     e.printStackTrace();
   }
  }
  }
