【文件导出2】导出html文件数据

导出html文件数据

---

前言

springBoot项目实现在线导出html文件数据的功能。

---

一、实现代码

1.controller层

@GetMapping("/record/_export")
@ApiOperation("查询记录导出")
public void recordExport(HttpServletResponse response, RecordSearchRequest query) throws IOException {
   
        ruleVerifyResultService.recordExport(response, query);
    }

RecordSearchRequest为请求查询条件，根据条件导出对应的记录。

2.接口层

public interface ResultService extends IService<RuleVerifyResultEntity> {
   
 /**
     * 记录导出
     * @param query
     * @return
     */
    void recordExport(HttpServletResponse response, RecordSearchRequest query) throws IOException;
}

3.接口实现类

@Override
public void queryRecordExport(HttpServletResponse response, RuleVerifyRecordSearchRequest query) throws IOException {
   
        LocalDateTime startExecuteTime = null;
        LocalDateTime endExecuteTime = null;
        //设置导出文件名称
        String fileName = "检验记录列表数据";
        if (ObjectUtils.isNotEmpty(query.getExecuteStartTime())) {
   
            startExecuteTime = query.getExecuteStartTime().atStartOfDay();
            endExecuteTime = query.getExecuteStartTime().atTime(23, 59, 59);
        }
       //查询需要导出的数据，用list集合接收
        List<RuleVerifyRecordEntity> recordList = ruleVerifyRecordMapper.selectList(Wrappers.<RuleVerifyRecordEntity>lambdaQuery().
                // 关键字搜索
                and(StringUtils.isNotEmpty(query.getKeywords()), wrapper -> 
	          wrapper.like(RuleVerifyRecordEntity::getTableName, query.getKeywords()).
                        or().like(RuleVerifyRecordEntity::
