SpringBoot+EasyExcel实现excel导入功能（含postman调试教程）

需求：现在需要完成通过post请求上传excel文件，并保存入库的功能

技术：SpringBoot + EasyExcel + postman 

---

 1.新增EasyExcel 依赖

      com.alibaba
      easyexcel
      2.1.6

 2.新增excel数据对应的对象

package com.example.demo.model;

import com.alibaba.excel.annotation.ExcelProperty;
import lombok.Data;

/**
 * @author LWong
 * @date 2020/03/06
 */
@Data
public class ExportInfo {
    //@ExcelProperty注解可以使用value或者index进行匹配字段，不建议 index 和 name 同时用
    @ExcelProperty(value = "web-scraper-order", index = 0)
    private String order;

    @ExcelProperty(value = "web-scraper-start-url", index = 1)
    private String url;

    @ExcelProperty(value = "num", index = 2)
    private String num;

}

对应的excel数据是这样的，@ExcelProperty对应着表头信息

3. 新建监听器

package com.example.demo.util.excel;

import com.alibaba.excel.context.AnalysisContext;
import com.alibaba.excel.event.AnalysisEventListener;
import com.alibaba.fastjson.JSON;
import com.google.common.collect.Lists;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.util.List;


/**
 * @author LWong
 * @date 2020/03/06
 */
public class ExcelListener extends AnalysisEventListener {

    private final static Logger LOGGER = LoggerFactory.getLogger(ExcelListener.class);

    private static final int BATCH_COUNT = 5;

     private List
