java中如何导入Excel,并给出模板

一般使用jxl或poi需要相关jar

poi的直接去Apache去下载就行了

下面写意个jxl子

String fi = “Excel文件路径”;

//设置字

WorkbookSettings workbooksetting = new WorkbookSettings();

workbooksetting.setEncoding(“GBK”);

//构造Workbook(工作薄)对象,此先将EXCEL文件装入内存,易引起内存溢出!

InputStream is = new FileInputStream(fi);

Workbook wb = Workbook.getWorkbook(is,workbooksetting);

// 获得了Workbook对象之后,就可以通过它得到Sheet(工作表)对象了

Sheet[] s = wb.getSheets();

for (Sheet sh : s) {

int rows = sh.getRows();

for (int i = 1; i < rows; i ) {

Cell[] cells = sh.getRow(i);

//这里可以读取第i行的xx格内容了cells[xx].getContents()

System.out.println(cells[0].getContents().trim().replaceAll(“\\s”, “”));

}

}

java批量导入excel

两种方案:

1. 可以对数据库表进行本地缓存处理,验证时调用缓存进行验证。

2. 用生成需要导入excel的数据模板,在模板里将要验证的这一列做成下拉框。此模板条件下的excel数据文件批量导入时即不用校验。

具体采用哪种视你的应用场景来定。

如何把excel数据导入java

用方组poi读取,给个例参下

public class ApachePOIExcelRead {

private static final String FILE_NAME = “/tmp/MyFirstExcel.xlsx”;

public static void main(String[] args) {

try {

FileInputStream excelFile = new FileInputStream(new File(FILE_NAME));

Workbook workbook = new XSSFWorkbook(excelFile);

Sheet datatypeSheet = workbook.getSheetAt(0);

Iterator iterator = datatypeSheet.iterator();

while (iterator.hasNext()) {

Row currentRow = iterator.next();

Iterator cellIterator = currentRow.iterator();

while (cellIterator.hasNext()) {

Cell currentCell = cellIterator.next();

//getCellTypeEnum shown as deprecated for version 3.15

//getCellTypeEnum ill be renamed to getCellType starting from version 4.0

if (currentCell.getCellTypeEnum() == CellType.STRING) {

System.out.print(currentCell.getStringCellValue() “–“);

} else if (currentCell.getCellTypeEnum() == CellType.NUMERIC) {

System.out.print(currentCell.getNumericCellValue() “–“);

}

}

System.out.println();

}

} catch (FileNotFoundException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}

}
