如何对 Excel 表格中提取的数据进行批量更新

//Mapper层
    public int updateFlagByEmployeeID(@Param("ids") List<String> ids);
//XML文件中
    <update id="updateFlagByEmployeeID">
        update OA_JDY_Personnel_Info_Test set enableFlag = 1
        where employeeID in
        <foreach collection="ids" separator="," item="employeeID" open="(" close=")">
            #{employeeID}
        </foreach>
    </update>

    public String enableFlagUpdate(String filename) {
        //获取 PersonSynData 类的 Class 对象。
        Class<PersonSynData> head = PersonSynData.class;
        List<PersonSynData> updateList = new ArrayList<>();
        ExcelReader excelReader = EasyExcel.read(filename, head, new AnalysisEventListener<PersonSynData>() {
            @Override
            public void invoke(PersonSynData personSynData, AnalysisContext analysisContext) {
                updateList.add(personSynData);
            }
            @Override
            public void doAfterAllAnalysed(AnalysisContext analysisContext) {
                System.out.println("Excel解析完成......");
            }
        }).build();
        //创建 sheet 对象,并且读取Excel的第一个sheet(下表从0开始),也可以根据 sheet 名称获取
        ReadSheet readSheet = EasyExcel.readSheet(0).build();
        //读取 sheet 表格数据,参数是可变参数,也可以读取多个sheet
        //这个操作会读取 excel 表格的数据
        excelReader.read(readSheet);
        //需要自己关闭流操作,在读取文件的时候会创建临时文件,如果不关闭的话,会损耗磁盘
        excelReader.finish();
        String success = "";
        //创建更新集合
        List<String> employeeIDs = new ArrayList<>();
        for(int i = 0; i < updateList.size(); i++){
            //这里可以拿到表格内的所有数据,根据表格中的员工号,批量修改Flag
            String employeeID = updateList.get(i).getEmployeeID();
            employeeIDs.add(employeeID);
        }
        int totalUpdatedCount = 0;
        for (int i = 0; i < employeeIDs.size(); i += BATCH_SIZE) {
            List<String> batchIds = employeeIDs.subList(i, Math.min(i + BATCH_SIZE, employeeIDs.size()));
            int updatedCount = jdcloudDao.updateFlagByEmployeeID(batchIds);
            totalUpdatedCount += updatedCount;
        }
        //进行批量更新 每次只更新 2008条
        //int count = jdcloudDao.updateFlagByEmployeeID(employeeIDs);
        return "更新成功的条数：" + totalUpdatedCount + "<br>";
    }
