java导出excel表格 使用alibaba easyexcel

开发中有好多时候需要导出表格，以往通常使用poi 这些jar进行倒入导出。
最近发现 阿里巴巴的一个 easyexcel 导出非常方便 记录下
项目地址

先添加依赖

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>easyexcel</artifactId>
            <version>1.1.2-beta5</version>
        </dependency>

controller 层

   public void  downloadPointsList(@RequestParam(defaultValue = "0",required = false) int type ,
                                    @RequestParam(defaultValue = "",required = false) String  begintime,
                                    @RequestParam(defaultValue = "",required = false) String  endtime
                                    , HttpServletResponse response) throws IOException {
        List<MemberPoints> downLoads = memberPointsService.downloadBytime(type,begintime,endtime);
        OutputStream out = response.getOutputStream();
        ExcelWriter writer =new ExcelWriter(out, ExcelTypeEnum.XLSX);
        Sheet sheet1 =new Sheet(1, 0, MemberPoints.class);
        sheet1.setSheetName("会员积分");
        response.setCharacterEncoding("utf-8");
        response.setContentType("application/vnd.ms-excel;charset=utf-8");
        response.setHeader("Content-Disposition", "attachment;filename=" +new String(( "会员积分数据.xlsx").getBytes(), "ISO8859-1"));
        writer.write(downLoads, sheet1);
        writer.finish();
        out.flush();
        out.close();
    }

这里阿里是根据 实体类的注解 去生成表头对应的

public class MemberPoints  extends BaseRowModel {

    /**
     * ID
     */
     @ExcelProperty(value = "ID",index = 0)
    private Long id;

    /**
     * 会员ID
     */
    @ExcelProperty(value = "会员ID",index = 1)
    private Long memberId;

    /**
     * 类型 1获得 2 支出
     */
     @ExcelProperty(value = "类型",index =5)
    private Integer type;


}
