JXL導出excel表

1、項目結構

2、準備jar包只需要jxl.jar就可以

3、書寫Jxl2Excel.java

package com.hhj.excel;

import java.io.File;
import java.util.ArrayList;
import java.util.List;

import com.hhj.domain.User;

import jxl.Workbook;
import jxl.write.Label;
import jxl.write.WritableCellFormat;
import jxl.write.WritableFont;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;
import jxl.write.WriteException;
import jxl.write.biff.RowsExceededException;

public class Jxl2Excel {

	
	public static void createTitle(WritableSheet sheet,List<String> list) throws RowsExceededException, WriteException{
		if(list!=null && list.size()>0){
			WritableFont wf = new WritableFont(WritableFont.ARIAL, 18,WritableFont.BOLD, false,jxl.format.UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.BLACK);
			WritableCellFormat wcfF = new WritableCellFormat(wf);
			for(int i=0;i<list.size();i++) {
				Label label = new Label(i, 0, list.get(i), wcfF);
				sheet.addCell(label);
			}
		}
		
	}
	
	public static void main(String[] args) throws Exception {

		File file = new File("F:\\test.xls");
		if (!file.exists()) {
			file.createNewFile();
		}

		//創建一個excel
		WritableWorkbook book = Workbook.createWorkbook(file);
		//生成名爲"信息"的sheet，參數0表示這是第一頁
		WritableSheet sheet1 = book.createSheet("信息", 0);
		WritableSheet sheet2 = book.createSheet("信息2", 1);
		
		
		//標題list
		List<String> lt = new ArrayList<String>();
		lt.add("賬號");
		lt.add("姓名");
		lt.add("電話號碼");
		//創建標題
		createTitle(sheet1, lt);
		
		
		// 內容list
		List<User> list = new ArrayList<User>();
		
		User user = new User();
		user.setAccount("001");
		user.setName("123");
		user.setTel("11111");
		list.add(user);
		
		User user1 = new User();
		user1.setAccount("002");
		user1.setName("456");
		user1.setTel("22222");
		list.add(user1);
		
		for(int i=0;i<list.size();i++) {
			int x = 0;
			Label label = new Label(x++, i+1, list.get(i).getAccount());
			Label label2 = new Label(x++, i+1, list.get(i).getName());
			Label label3 = new Label(x++, i+1, list.get(i).getTel());
			sheet1.addCell(label);
			sheet1.addCell(label2);
			sheet1.addCell(label3);
		}
		book.write();
		book.close();
		System.out.println("生成excel文件成功");
	}

}

4、domain類User.java

package com.hhj.domain;

public class User {
	private String account;
	private String name;
	private String tel;
	
	public String getAccount() {
		return account;
	}
	public void setAccount(String account) {
		this.account = account;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getTel() {
		return tel;
	}
	public void setTel(String tel) {
		this.tel = tel;
	}
	
}

總結：

使用jxl導出excel相對來說比較簡單，整體只需要三步

1.WritableWorkbook book = Workbook.createWorkbook(file);

2.WritableSheet sheet1 = book.createSheet("信息", 0); //0表示從第一列開始

3.Label label = new Label(x++, i+1, list.get(i).getAccount());
   sheet1.addCell(label);
