Excel导出实例

在上一节的基础上，本文演示下如何导出excel数据。

Excel导出操作演示

继承ocean-easyexcel SDK

<dependency>
    <groupId>com.angel.ocean</groupId>
    <artifactId>ocean-easyexcel</artifactId>
    <version>1.0.0</version>
</dependency>

定义Excel数据导出模型

package com.angel.ocean.domain.vo;

import com.alibaba.excel.annotation.ExcelProperty;
import com.alibaba.excel.annotation.write.style.*;
import com.alibaba.excel.enums.BooleanEnum;
import com.alibaba.excel.enums.poi.BorderStyleEnum;
import com.alibaba.excel.enums.poi.FillPatternTypeEnum;
import com.alibaba.excel.enums.poi.HorizontalAlignmentEnum;
import com.alibaba.excel.enums.poi.VerticalAlignmentEnum;
import lombok.Data;

/**
 * Excel导出数据结构样例
 */
@HeadStyle(fillPatternType = FillPatternTypeEnum.DEFAULT, horizontalAlignment = HorizontalAlignmentEnum.CENTER, verticalAlignment = VerticalAlignmentEnum.CENTER, borderTop = BorderStyleEnum.THIN, borderRight = BorderStyleEnum.THIN, borderBottom = BorderStyleEnum.THIN, borderLeft = BorderStyleEnum.THIN)
@HeadRowHeight(value = 20)
@HeadFontStyle(fontHeightInPoints = 11, bold = BooleanEnum.TRUE)
@ContentRowHeight(value = 20)
@ContentStyle(horizontalAlignment = HorizontalAlignmentEnum.CENTER, verticalAlignment = VerticalAlignmentEnum.CENTER, borderTop = BorderStyleEnum.THIN, borderRight = BorderStyleEnum.THIN, borderBottom = BorderStyleEnum.THIN, borderLeft = BorderStyleEnum.THIN)
@Data
public class UserDataExportVO {

    @ExcelProperty("用户名")
    @ColumnWidth(20)
    private String username;

    @ExcelProperty("密码")
    @ColumnWidth(20)
    private String password;

    @ExcelProperty("注册时间")
    @ColumnWidth(30)
    private String createTime;
}

定义Excel导入接口

/**
* 导出excel
 * @param response
 */
@GetMapping("export")
public void exportExcel(HttpServletResponse response) {

    List<UserDataExportVO> exportData = new ArrayList<>();

    for(int i = 0; i < 16; i++) {
        UserDataExportVO userDataExportVO = new UserDataExportVO();
        userDataExportVO.setUsername("admin");
        userDataExportVO.setPassword("123456");
        userDataExportVO.setCreateTime("2022-04-24 10:56");
        exportData.add(userDataExportVO);
    }

    EasyExcelUtil.writeExcel(response,System.currentTimeMillis()  + ".xlsx" ,"EXCEL导出数据", exportData, UserDataExportVO.class);

}
