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 {

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");  
    }
