easypoi一对多子集导入导出,@ExcelCollection注解的使用。

easypoi一对多子集导入导出。使用@ExcelCollection注解。

TestController：

import cn.afterturn.easypoi.excel.ExcelImportUtil;
import cn.afterturn.easypoi.excel.entity.ImportParams;
import com.xingyi.hos.model.response.ResponseObjectResult;
import com.xingyi.hos.model.response.ResponseStatus;
import com.xingyi.hos.model.response.ResultCode;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestPart;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

import java.util.List;

/**

@Api(value = "设备台账接口",description = "设备台账接口")
@RestController

@Slf4j
public class TestController {
    @PostMapping("/import")
    @ApiOperation(value = "设备台账导入", notes = "liuyachao")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "Token", value = "token",  required = true, paramType = "header", dataType = "string"),
            @ApiImplicitParam(name = "file", value = "需要导入的excel文件", required = true, paramType = "form", dataType = "file")
    })
    public ResponseObjectResult importEquipmentAccounts(@RequestPart(value = "file") MultipartFile file) {
        try {
            ImportParams params = new ImportParams();
            params.setTitleRows(0);
            params.setHeadRows(2);
            List<Question> questionList = ExcelImportUtil.importExcel(file.getInputStream(),Question.class,params);
            log.info("questionList:{}",questionList);
            return new ResponseObjectResult(new ResponseStatus(ResultCode.SUCCESS));
        } catch (Exception e) {
            log.error("importEquipmentAccounts 设备台账导入,异常：",e);
            return new ResponseObjectResult(new ResponseStatus(ResultCode.FAIL));
        }
    }
}

Question：

import cn.afterturn.easypoi.excel.annotation.Excel;
import cn.afterturn.easypoi.excel.annotation.ExcelCollection;
import lombok.Data;

import java.io.Serializable;
import java.util.List;

/**
 * Created by Administrator on 2022/7/19.
 */
@Data
public class Question implements Serializable{
    private static final long serialVersionUID = 4349471525156143284L;
    @Excel(name = "所属学科",needMerge = true)
    private String subject;
    @Excel(name = "知识点",needMerge = true)
    private String konwledge;
    @Excel(name = "类型",needMerge = true)
    private String tmType;
    @Excel(name = "案例",needMerge = true)
    private String content;
    @ExcelCollection(name = "选项")
    private List<QuestionChild> childList;
}

QuestionChild：

import cn.afterturn.easypoi.excel.annotation.Excel;
import lombok.Data;

import java.io.Serializable;

/**
 * Created by Administrator on 2022/7/19.
 */
@Data
public class QuestionChild implements Serializable{
    private static final long serialVersionUID = -6141999253465493661L;
    @Excel(name = "题目")
    private String title;
    @Excel(name = "子题型")
    private String type;
}

结果如图：

可以获取到子列表：

 导入的Excel表格：

导出同理。实体相同调用导出。
