#for循环

代码段1展示了遍历List<DeploymentWellDeploymentVo>，获取每个实体的FileVo列表，设置下载和预览Url。代码段2中，遍历List<Map<String,Object>>，根据dbid获取FileVo列表并添加到Map中。

1.for循环list<实体>

   List<DeploymentWellDeploymentVo> resultList = DeploymentMapper.selectList(wellDeploymentVo);
 for (DeploymentWellDeploymentVo deployment : resultList) {
            List<FileVo> fileVos= fjghwjxxMapper.getFileList(deployment.getDbid());
            if(fileVos.size()>0){
                for (FileVo fileVo : fileVos) {
                    fileVo.setDownloadUrl(downLoadUrl+fileVo.getFileId());
                    fileVo.setPreviewUrl(previewUrl+fileVo.getFileId());
                }
            }
            deployment.setFileList(fileVos);
        }

2。for循环List<Map<String, Object>>

  List<Map<String, Object>> resultList = oilWellComAcceptanceMapper.queryList(oilWellCompletionAcceptance);

        for (Map<String, Object> map : resultList) {
            if(StringUtils.isNotEmpty(map.get("dbid").toString())) {
                List<FileVo> fileVos = fjghwjxxService.getFileListBySSBM(map.get("dbid").toString(), SSBM);
                map.put("fileList", fileVos);
            }
        }
