我正在尝试为这个包含两列的 CSV 文件编写规范器。BIN（第一行中的数字）和 BBL（第二行中的字符串）。然后我写了一个 JUnit 测试（在这个规范器下看到）。当我运行 Junit 测试时，我得到一个方法“初始化错误”未找到。打开测试班。有人可以帮帮我吗。

CSV 如下所示：

BIN    boro
10001  Finnacial 
...

归一化器

      package bah.placebook.data.normalization.impl;

      import java.util.HashMap;

      import org.apache.log4j.Logger;
      import org.springframework.stereotype.Component;

      import bah.placebook.data.models.Building;
      import bah.placebook.data.normalization.util.LatLongUtil;


  @Component
   public class Neighborhood_Normalizer_CSV extends BuildingDataCSVNormalizer {




  private static final Logger log = Logger.getLogger(Neighborhood_Normalizer_CSV.class);


     @Override

      public String getDatasetId(){
        return"Neighborhood_data";
    }

      @Override
    protected Building outputNormalizedRow(String[] csvRow){
        Building building = new Building();



    HashMap<String, Integer> columns = getColumnNames();


                 try {
                        building.setBin(Integer.parseInt(csvRow[columns.get("bin")]));
                         }  
                  catch (NumberFormatException e) {
                         log.error("Unable to extract BIN number",e);
                        return null;
                    }

                try {

            String bbl = csvRow[columns.get("boro")] + csvRow[columns.get("block")] +                               

           csvRow[columns.get("lot")];

           building.setBblNumber(Integer.parseInt(bbl.trim()));
   } 

        catch (NumberFormatException f) {

        log.error("Unable to extract BBL number",f);
   }
    return building;
    }

    }

  @Autowired

  @Test

   public void normalize() throws UnknownDataSetException, IOException {

    File testData = ResourceUtils.getFile("classpath:data/nieghborhood.csv");
    File normalizedData = folder.newFile();
    try(InputStream is = new FileInputStream(testData);
        OutputStream os = new FileOutputStream(normalizedData)) {
      nManager.normalizeDataset("nieghborhood",is , os);
    }

    try(BufferedReader reader = new BufferedReader(
          new InputStreamReader(new  FileInputStream(normalizedData)))) {
      String line = reader.readLine();
      while(line != null) {
        System.out.println(line);
        line = reader.readLine();
      }
    }
  }
}
