poi导入excel转化成实体类

1、Controller

//导入excel
	@RequestMapping(value = "/import", method=RequestMethod.POST)
	public JsonDto importExcel(@RequestParam(value="file",required = false) MultipartFile file,
							   HttpServletRequest request,
							   HttpServletResponse response){
		return  functionProjectRelationService.importExcelFile(file);
	}

2、Service

public JsonDto importExcelFile(MultipartFile file) {
		JsonDto jsonDto = new JsonDto();
		try{
			int successNum = 0;
			int failureNum = 0;
			ImportExcel ei = new ImportExcel(file, 0, 0);
			List list = ei.getDataList(User.class);
			logger.info("导入" + list.size() + "条数据");
			jsonDto.setSuccess(Boolean.TRUE);
			jsonDto.setErrcode("200");
			jsonDto.setErrmsg("上传成功");
			jsonDto.setData(list);
		}catch(Exception e){
			e.printStackTrace();
			jsonDto.setSuccess(Boolean.TRUE);
			jsonDto.setErrcode("-1");
			jsonDto.setErrmsg("上传异常"+e.getMessage());
			jsonDto.setData(new JSONObject());
			return jsonDto;
		}
		return  jsonDto;
	}

3、User.java

package com.elink.estos.common.utils.excel;

import com.elink.estos.common.utils.excel.annotation.ExcelField;

/**
 * @Auther: yinzuomei
 * @Date: 2019/9/3 13:51
 * @Description:
 */
public class User {
    private String name;
    private String sex;
    private String age;
    private String address;
    @ExcelField(title="姓名", align=1,sort = 1)
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
    @ExcelField(title="性别", align=1,sort = 2)
    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }
    @ExcelField(title="年龄", align=1,sort = 3)
    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }
    @ExcelField(title="地址", align=1,sort = 4)
    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

4、工具类修改
