有人知道在 Hibernate 中有解决这个问题的方法吗？
非常感谢任何帮助，谢谢！

作为对这个问题的解决方法，可以将数据分块获取。
List<List<Long>> partitions = new ArrayList<List<Long>>();
List<Long> bucket = new ArrayList<>();
int count = 0;
for (Long id : ids) {
count++;
if (count > 1000) {
count = 1;
partitions.add(bucket);
bucket = new ArrayList<>();
}
partitions.add(bucket);
}
List<PreStagePaymentData> data = new ArrayList<>();
List<PreStagePaymentData> temp;
for (List<Long> partition : partitions) {
temp = findPreStageDataByPaymentIds(partition);
data.addAll(temp);
}
英文:
As a workaround for this issue would be to get data in chunks.
List<List<Long>> partitions = new ArrayList<List<Long>>();
List<Long> bucket = new ArrayList<>();
int count = 0;
for(Long id : ids){
count++;
if(count>1000){
count = 1;
partitions.add(bucket);
bucket = new ArrayList<>();
}
partitions.add(bucket);
}
List<PreStagePaymentData> data= new ArrayList<>();
List<PreStagePaymentData> temp;
for(List<Long> partition : partitions){
temp = findPreStageDataByPaymentIds(partition);
data.addAll(temp);
}
