一 场景

将前端form表单中的内容整个传给后端，处理后导出为word文档

二 实现

前端表单

<!-- 导出数据内容对话框表单 -->
    <el-dialog :title="title" :visible.sync="exportShow" width="500px" class="narrow" append-to-body v-if="exportShow" :close-on-click-modal="false">
      <el-form ref="eform" :model="eform" :rules="exportRules" label-width="80px" v-if="exportShow">
        <el-form-item label="编写日期" prop="writeDate">
          <el-date-picker clearable
                          v-model="eform.writeDate"
                          type="date"
                          value-format="yyyyMMdd"
                          placeholder="请选择编写日期"
                          style="width:250px">
          </el-date-picker>
        </el-form-item>
        <el-form-item label="编写人" prop="writer" >
          <el-input v-model="eform.writer" placeholder="请输入编写人" style="width:250px"/>
        </el-form-item>
        <el-form-item label="批准日期" prop="approveDate" >
          <el-date-picker clearable
                          v-model="eform.approveDate"
                          type="date"
                          value-format="yyyyMMdd"
                          placeholder="请选择批准日期"
                          style="width:250px">
          </el-date-picker>
        </el-form-item>
        <el-form-item label="批准人" prop="approver">
          <el-input v-model="eform.approver" placeholder="请输入批准人"  style="width:250px"/>
        </el-form-item>
      </el-form>
      <div slot="footer" class="dialog-footer">
        <el-button type="primary" @click="exportSubmitForm">确 定</el-button>
        <el-button @click="cancel">取 消</el-button>
      </div>
    </el-dialog>

前端导出操作代码

 exportList(){
      listContent().then(response =>{
        // 导出
        // console.log(this.eform);
        exportContent(this.eform).then(response =>{
          let data = new Blob([response], { type: 'application/msword,charset=utf-8' });
          if (typeof window.chrome !== 'undefined') {undefined
            // chrome
            const link = document.createElement('a');
            link.href = window.URL.createObjectURL(data);
            link.download = this.getDateStringForFileName()+"期间核查计划";
            link.click();
          }
        })
      });
    },

后端构建表单数据实体类DataPeriodInspectPublic

package com.ruoyi.system.domain;

import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;

import com.fasterxml.jackson.annotation.JsonFormat;
import com.ruoyi.common.core.domain.entity.SysDictData;
import com.ruoyi.system.domain.vo.DataPeriodInspectContentVo;
import org.apache.commons.lang3.builder.ToStringBuilder;
import org.apache.commons.lang3.builder.ToStringStyle;
import com.ruoyi.common.annotation.Excel;
import com.ruoyi.common.core.domain.BaseEntity;

/**
 * 期间表对象 data_period_inspect_public
 * 
 * @author ruoyi
 * @date 2022-06-20
 */
public class DataPeriodInspectPublic extends BaseEntity
{
    private static final long serialVersionUID = 1L;

    /** 主键 */
    private Long id;


    /** 选择的主键数组 */
    private Long[] ids;

    /** 年度 */
    @Excel(name = "年度")
    private String year;

    /** 编写 */
    @Excel(name = "编写")
    private String writer;

    /** 编写日期 */
    @JsonFormat(pattern = "yyyyMMdd")
    @Excel(name = "编写日期", width = 30, dateFormat = "yyyy-MM-dd")
    private String writeDate;

    /** 批准 */
    @Excel(name = "批准")
    private String approver;

    /** 批准日期 */
    @JsonFormat(pattern = "yyyyMMdd")
    @Excel(name = "批准日期", width = 30, dateFormat = "yyyy-MM-dd")
    private String approveDate;

    public Long[] getIds() {
        return ids;
    }

    public void setIds(Long[] ids) {
        this.ids = ids;
    }

    public void setId(Long id) 
    {
        this.id = id;
    }

    public Long getId() 
    {
        return id;
    }
    public void setYear(String year) 
    {
        this.year = year;
    }

    public String getYear() 
    {
        return year;
    }
    public void setWriter(String writer) 
    {
        this.writer = writer;
    }

    public String getWriter() 
    {
        return writer;
    }
    public void setWriteDate(String writeDate)
    {
        this.writeDate = writeDate;
    }

    public String  getWriteDate()
    {
        return writeDate;
    }
    public void setApprover(String approver) 
    {
        this.approver = approver;
    }

    public String getApprover() 
    {
        return approver;
    }
    public void setApproveDate(String  approveDate)
    {
        this.approveDate = approveDate;
    }

    public String getApproveDate()
    {
        return approveDate;
    }

    @Override
    public String toString() {
        return new ToStringBuilder(this, ToStringStyle.MULTI_LINE_STYLE)
                .append("year", getYear())
                .append("writer", getWriter())
                .append("writeDate", getWriteDate())
                .append("approver", getApprover())
                .append("approveDate", getApproveDate())
                .toString();
    }
}

后端controller接收表单数据并导出

/**
     * 导出期间数据内容列表
     */
    @PreAuthorize("@ss.hasPermi('system:content:export')")
    @Log(title = "期间数据内容", businessType = BusinessType.EXPORT)
    @PostMapping("/export")
    public void export(HttpServletResponse resp, HttpServletRequest req, @RequestBody DataPeriodInspectPublic publicList)
    {
        //获取期间数据内容列表
        List<DataPeriodInspectContentVo> list = dataPeriodInspectContentService.selectDataPeriodInspectContentByIds(publicList.getIds());

        //获取字典
        HashMap<String, ArrayList<SysDictData>> dictData = dictDataService.getAllDictDataMap();

        //生成结果集
        Map<String, Object> dataMap = new HashMap<String,Object>();
        ArrayList<TempDataPeriodInspectContent> resultList=new ArrayList<TempDataPeriodInspectContent>();
        for (DataPeriodInspectContentVo c:list){
            resultList.add(new TempDataPeriodInspectContent(c,dictData));
        }

        dataMap.put("contentList",resultList);
        dataMap.put("public",publicList);
        //设置生成文件存储路径
        String directory="/contentList";
        WordUtil.CheckDownloadPath(directory);
        //生成文件
        WordUtil.CreateWord(resp,req,dataMap,RuoYiConfig.getTemplatePath()+"/dataPeriodInspectContent","BKJC-CX-006-1.ftl"
                , RuoYiConfig.getDownloadPath()+directory+"/BKJC-CX-006-1.doc");
        //下载后删除生成文件
        FileUtils.deleteFile(RuoYiConfig.getDownloadPath()+directory+"/BKJC-CX-006-1.doc");
    }

js文件连接前后端

// 导出期间数据内容
export function exportContent(data){
  return request({
    url:'/system/content/export' ,
    method: 'post',
    data: data
  })
}
