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();   }  }  }
