peiyou opened a new issue #3713: How do you return the auto-generated id after inserting data?
URL: https://github.com/apache/incubator-shardingsphere/issues/3713
 
 
   How do you return the auto-generated id after inserting data?
   
   My configuration:
   spring.shardingsphere.sharding.tables.transaction.key-generator.column=id
   spring.shardingsphere.sharding.tables.transaction.key-generator.type=SNOWFLAKE
   spring.shardingsphere.sharding.tables.transaction.key-generator.props.worker.id=123
   
   spring.shardingsphere.sharding.tables.transaction_item.key-generator.column=id
   spring.shardingsphere.sharding.tables.transaction_item.key-generator.type=SNOWFLAKE
   spring.shardingsphere.sharding.tables.transaction_item.key-generator.props.worker.id=124
   
   LOG:
   INSERT INTO transaction_201912  ( user_id,amount,created_time , id) VALUES(?, ?, ?, ?) ::: [1, 300, 2019-12-11 11:23:27.853, 411482226929676289]
   
   I want to get the auto-generated id after inserting the data.
   
   My code:
   Transaction transaction = new Transaction();
           transaction.setUserId(userId);
           transaction.setAmount(amount);
           transaction.setCreatedTime(new Date());
           transactionService.insert(transaction);
   
           TransactionItem transactionItem = new TransactionItem();
           transactionItem.setTransactionId(transaction.getId());
           transactionItem.setNum(num);
           transactionItem.setGoodName("1");
           transactionItem.setPrice(price);
           transactionItem.setCreatedTime(new Date());
   
           transactionItemService.insert(transactionItem);
   BUT:
   transaction.getId() is null.   
   What should I do?
