postgresql批量新增数据时，批量插入的数据量太大了，造成了IO异常

只能把这么多数据先进行分割，再批量插入，但是感觉这种方式不是最优解，先暂时顶着，具体List分割方式如下：

package cn.ucmed.otaka.healthcare.cloud.util;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class PartitionArray<T> {

    public Map<Integer, List<T>> partition(List<T> tArray, int capacity) {
        if (tArray.isEmpty() || capacity < 1) {
            return null;
        }
        Map<Integer, List<T>> result = new HashMap<>();

        int size = tArray.size();
        int count = ((Double) Math.ceil(size * 1.0 / capacity)).intValue();

        for (int i = 0; i < count; i++) {
            int end = capacity * (i + 1);
            if (end > size) end = size;
            result.put(i, tArray.subList(capacity * i, end));
        }
        return result;
    }
}

原先批量调用的地方做个处理：

        try {
            PartitionArray<MDynamicFuncReleaseHistory> partitionArray = new PartitionArray<>();
            Map<Integer, List<MDynamicFuncReleaseHistory>> batchList = partitionArray.partition(releaseHistoryList, INSERT_CAPACITY);
            batchList.forEach((k, v) -> {
                mDynamicFuncReleaseHistoryMapper.batchInsert(v);
            });
        } catch (Exception e) {
            log.error(e.getMessage());
            throw new BusinessException(500, "新增MDynamicFuncReleaseHistory失败");
        }
