问题： - 导入成功条数显示为负数 - 原因：成功数量计算使用 validRecords.size() - failures.size() - 但没有使用实际的数据库操作返回值 修复： - saveBatchWithUpsert 和 saveBatch 方法现在返回 int - 累加实际的数据库影响行数 - 使用 actualSuccessCount 变量跟踪真实成功数量 影响范围： - CcdiIntermediaryPersonImportServiceImpl - CcdiIntermediaryEntityImportServiceImpl

ZipStream
zip-stream is a streaming zip archive generator based on the ZipArchiveOutputStream prototype found in the compress-commons project.
It was originally created to be a successor to zipstream.
Visit the API documentation for a list of all methods available.
Install
npm install zip-stream --save
You can also use npm install https://github.com/archiverjs/node-zip-stream/archive/master.tar.gz to test upcoming versions.
Usage
This module is meant to be wrapped internally by other modules and therefore lacks any queue management. This means you have to wait until the previous entry has been fully consumed to add another. Nested callbacks should be used to add multiple entries. There are modules like async that ease the so called "callback hell".
If you want a module that handles entry queueing and much more, you should check out archiver which uses this module internally.
const Packer = require('zip-stream');
const archive = new Packer(); // OR new Packer(options)
archive.on('error', function(err) {
throw err;
});
// pipe archive where you want it (ie fs, http, etc)
// listen to the destination's end, close, or finish event
archive.entry('string contents', { name: 'string.txt' }, function(err, entry) {
if (err) throw err;
archive.entry(null, { name: 'directory/' }, function(err, entry) {
if (err) throw err;
archive.finish();
});
});

Concept inspired by Antoine van Wel's zipstream module, which is no longer being updated.
