Весенняя партия: ресурс ввода не существует Ресурс пути класса

Question

В настоящее время я разрабатываю весеннюю партию, которая преобразует файл Excel (.xsls) в CVS на первом шаге, а затем читает процесс CVS и сохраняет его данные в базе данных. Первый шаг работает хорошо. Партия останавливается на втором шаге, бросая это предупреждение: входной ресурс не существует ресурса пути класса [C: /work/referentielAgenceCE.csv]. Вот после того, как мой код:

весна-config.xml:

step1: convertXLSXtoCVS.java

public class convertXLSXtoCVS implements Tasklet, InitializingBean{ 


    @Value("${batch.referentielAgenceCE.inputFilePathXLSX}") 
    private String inputFile; 

    @Override 
    public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) 
      throws Exception { 
     System.out.println("convertXLSXtoCVS.execute1"); 
     // For storing data into CSV files     
     StringBuffer data = new StringBuffer();     
     try { 
      File outputFile = new File(getOutputFile(inputFile)); 
      FileWriter fw = new FileWriter(outputFile.getPath()); 

      BufferedWriter fos = new BufferedWriter(fw); 

      // Get the workbook object for XLSX file 
      XSSFWorkbook wBook = new XSSFWorkbook(new FileInputStream(inputFile)); 

      // Get first sheet from the workbook 
      XSSFSheet sheet = wBook.getSheetAt(0); 
      Row row; 
      Cell cell; 

      // Iterate through each rows from first sheet 
      Iterator<Row> rowIterator = sheet.iterator(); 
      while (rowIterator.hasNext()) { 
       row = rowIterator.next(); 
       // For each row, iterate through each columns 
       Iterator<Cell> cellIterator = row.cellIterator(); 
       while (cellIterator.hasNext()) { 
        cell = cellIterator.next(); 
        switch (cell.getCellType()) { 
         case Cell.CELL_TYPE_BOOLEAN:             
          data.append(cell.getBooleanCellValue() + ",");             
          break;           
         case Cell.CELL_TYPE_NUMERIC:             
          data.append(cell.getNumericCellValue() + ",");             
          break;           
         case Cell.CELL_TYPE_STRING:             
          data.append(cell.getStringCellValue() + ",");             
          break;           
         case Cell.CELL_TYPE_BLANK:             
          data.append("" + ",");             
          break; 
         default:             
          data.append(cell + ","); 
        } 
       } 
      } 
      fos.write(data.toString()); 
      fos.close(); 
     }catch (Exception ioe) { 
      ioe.printStackTrace(); 
     } 
     return RepeatStatus.FINISHED; 
    } 

    @Override 
    public void afterPropertiesSet() throws Exception { 
     Assert.notNull(inputFile, "inputFile must be set"); 

    } 

    public String getOutputFile(String inputFile){ 
     String[] parts = inputFile.split("\\."); 
     return parts[0]+"."+parts[1].replace("xlsx", "csv"); 
    } 

} 

Я упоминаю пути к файлам в файле свойств следующим образом:

batch.referentielAgenceCE.inputFilePathXLSX=C\:\\work\\referentielAgenceCE.xlsx 
batch.referentielAgenceCE.inputFilePathCSV=C\:\\work\\referentielAgenceCE.csv 

Когда я удалю из spring-config.xml в определении читателя, я получаю следующую ошибку:

Answer 1

Я нашел решение. Я должен просто добавить 'file:' в выходной путь cvs файла. так что это должно быть так: batch.referentielAgenceCE.inputFilePathCSV = file: C: \ work \ referentielAgenceCE.csv вместо C: \ work \ referentielAgenceCE.csv

Answer 2

Зрение:

Caused by: java.lang.IllegalStateException: Input resource must exist (reader is in 'strict' mode): URL [file://work//referentielAgenceCE.csv] 

И более точно:

file://work//referentielAgenceCE.csv 

Я думаю, вам нужно заменить:

batch.referentielAgenceCE.inputFilePathXLSX=C\:\\work\\referentielAgenceCE.xlsx 
batch.referentielAgenceCE.inputFilePathCSV=C\:\\work\\referentielAgenceCE.csv 

по

batch.referentielAgenceCE.inputFilePathXLSX=C:\\work\\referentielAgenceCE.xlsx 
batch.referentielAgenceCE.inputFilePathCSV=C:\\work\\referentielAgenceCE.csv
