Java批量修改数据逻辑_java中es5.4版本批量修改数据

List<samples> samples = dao.getSamples();
 
if (samples.size() > 0) {
    final int total = samples.size();// 总记录数
    final int batchSize = 10000; // 每次插入记录数
    int toIndex = batchSize;   // 数据存一次的索引
    for(int fromIndex = 0; fromIndex < total; fromIndex += batchSize) {
        toIndex = Math.min(fromIndex + batchSize, total);
        // 拆分的提交数据
        List<ProSample> subList = samples.subList(fromIndex, toIndex);
        proSampleMapper.insertSampleBatch(businessId, subList);
    }
}
