Spring批处理：输入资源不存在类路径资源
我目前正在开发一个弹簧批处理，它在第一步将Excel（.xsls）文件转换为CVS，然后读取CVS处理它并将其数据存储在数据库中。 第一步效果很好。 批处理停止在第二步抛出此警告：输入资源不存在类路径资源[C：/work/referentielAgenceCE.csv]。 在我的代码之后：
spring-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 rowIterator = sheet.iterator(); while (rowIterator.hasNext()) { row = rowIterator.next(); // For each row, iterate through each columns Iterator 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"); } }
我在属性文件中提到文件路径如下：
batch.referentielAgenceCE.inputFilePathXLSX=C\:\\work\\referentielAgenceCE.xlsx batch.referentielAgenceCE.inputFilePathCSV=C\:\\work\\referentielAgenceCE.csv
当我从阅读器定义中的spring-config.xml中删除时，我收到以下错误：

我找到了解决方案。 我应该将’file：’添加到输出cvs文件路径中。 所以它应该是这样的：batch.referentielAgenceCE.inputFilePathCSV = file：C：\ work \ referentielAgenceCE.csv而不是C：\ work \ referentielAgenceCE.csv
看到：
Caused by: java.lang.IllegalStateException: Input resource must exist (reader is in 'strict' mode): URL [file://work//referentielAgenceCE.csv]
更确切地说：
file://work//referentielAgenceCE.csv
我认为你需要更换：
batch.referentielAgenceCE.inputFilePathXLSX=C\:\\work\\referentielAgenceCE.xlsx batch.referentielAgenceCE.inputFilePathCSV=C\:\\work\\referentielAgenceCE.csv
通过
batch.referentielAgenceCE.inputFilePathXLSX=C:\\work\\referentielAgenceCE.xlsx batch.referentielAgenceCE.inputFilePathCSV=C:\\work\\referentielAgenceCE.csv
