后台上传的逻辑：
@RequestMapping("/testImport") //导入 public Map<String, String> importabc(MultipartFile file) { Map<String, String> resultMap = Maps.newHashMap(); try { Workbook workbook = WorkbookFactory.create(file.getInputStream()); Sheet sheet = workbook.getSheetAt(0); for (int i = 0; i <= sheet.getLastRowNum(); i++) { Row row = sheet.getRow(i); if (row.getCell(0).getNumericCellValue() == 11){ resultMap.put("50023", "导入文件发生错误"); return resultMap; } System.out.println(row.getCell(0) + ";" + row.getCell(1) + ";" + row.getCell(2)); } } catch (IOException e) { e.printStackTrace(); } catch (InvalidFormatException e) { e.printStackTrace(); } resultMap.put("20000", "导入文件成功"); return resultMap; }
Excel中的内容：
可是导入时会抛出EOF异常，直接导致系统不可用，异常信息如下：

... 33 common frames omitted解决办法：
导入的方法不能将错误信息返回，而是应当通过抛异常的方式，让系统全局异常解析后返回。
现在将代码做如下修改，问题成功解决
@RequestMapping("/testImport") //导入 public void importabc(MultipartFile file) { try { Workbook workbook = WorkbookFactory.create(file.getInputStream()); Sheet sheet = workbook.getSheetAt(0); for (int i = 0; i <= sheet.getLastRowNum(); i++) { Row row = sheet.getRow(i); if (row.getCell(0).getNumericCellValue() == 11){ // 此异常信息应当被系统全局异常处理并返回 throw new ImportFileException("50023", "导入文件发生错误"); } System.out.println(row.getCell(0) + ";" + row.getCell(1) + ";" + row.getCell(2)); } } catch (IOException e) { e.printStackTrace(); } catch (InvalidFormatException e) { e.printStackTrace(); } }
