如果您正在使用HSSFWorkbook下面的使用

DVConstraint dvConstraint = 

DVConstraint.createExplicitListConstraint（new String [] {“ABC”}）; DataValidation dataValidation = new HSSFDataValidation（programList，dvConstraint）; dataValidation.setSuppressDropDownArrow（真）; dataValidation.setShowErrorBox（真）; dataValidation.setShowPromptBox（真）;

  targetSheet.addValidationData(dataValidation); For XSSFWorkbook, use as below DataValidationHelper validationHelper=new XSSFDataValidationHelper(targetSheet); DataValidationConstraint constraint =validationHelper.createExplicitListConstraint(new String[]{"ABC"}); DataValidation dataValidation = validationHelper.createValidation(constraint, programList); dataValidation.setSuppressDropDownArrow(true); dataValidation.setShowErrorBox(true); dataValidation.setShowPromptBox(true); targetSheet.addValidationData(dataValidation);
