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
buffer-crc32
crc32 that works with binary data and fancy character sets, outputs buffer, signed or unsigned data and has tests.
Derived from the sample CRC implementation in the PNG specification: http://www.w3.org/TR/PNG/#D-CRCAppendix
install
npm install buffer-crc32
example
var crc32 = require('buffer-crc32');
// works with buffers
var buf = Buffer([0x00, 0x73, 0x75, 0x70, 0x20, 0x62, 0x72, 0x6f, 0x00])
crc32(buf) // -> <Buffer 94 5a ab 4a>
// has convenience methods for getting signed or unsigned ints
crc32.signed(buf) // -> -1805997238
crc32.unsigned(buf) // -> 2488970058
// will cast to buffer if given a string, so you can
// directly use foreign characters safely
crc32('自動販売機') // -> <Buffer cb 03 1a c5>
// and works in append mode too
var partialCrc = crc32('hey');
var partialCrc = crc32(' ', partialCrc);
var partialCrc = crc32('sup', partialCrc);
var partialCrc = crc32(' ', partialCrc);
var finalCrc = crc32('bros', partialCrc); // -> <Buffer 47 fa 55 70>
tests
This was tested against the output of zlib's crc32 method. You can run
the tests withnpm test (requires tap)

https://github.com/alexgorbatchev/node-crc, crc.buffer.crc32 also
supports buffer inputs and return unsigned ints (thanks @tjholowaychuk).
