poi数据有效性下拉列表

定义函数

 

	public HSSFDataValidation SetDataValidation(String[] textList, int firstRow, int endRow, int firstCol, int endCol) {
		// 设置下拉列表的内容
		log.info("起始行:" + firstRow + "___起始列:" + firstCol + "___终止行:" + endRow + "___终止列:" + endCol);
		// 加载下拉列表内容
		DVConstraint constraint = DVConstraint.createExplicitListConstraint(textList);
		// DVConstraint constraint = new DVConstraint();
		constraint.setExplicitListValues(textList);

		// 设置数据有效性加载在哪个单元格上。
		// 四个参数分别是：起始行、终止行、起始列、终止列
		CellRangeAddressList regions = new CellRangeAddressList((short) firstRow, (short) endRow, (short) firstCol, (short) endCol);

		// 数据有效性对象
		HSSFDataValidation data_validation = new HSSFDataValidation(regions, constraint);

		return data_validation;
	}

 调用类

import java.io.FileOutputStream;
import java.io.IOException;

import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;

public class Test {
	public static void main(String[] args) throws IOException {
		HSSFWorkbook wb = new HSSFWorkbook();// excel文件对象
		HSSFSheet sheetlist = wb.createSheet("sheetlist");// 工作表对象
		FileOutputStream out = new FileOutputStream("success.xls");
		String[] textList = { "空闲1", "已用2" };
		sheetlist.addValidationData((new OracleToExcel()).SetDataValidation(textList, 1,2, 3, 4));
		wb.write(out);
		out.close();
	}
