前置內容：Seata 分佈式事務功能測試（一）
當前數據庫隔離級別爲 read_commit，測試調用服務後，再通過服務查詢時獲取的數據是否正確。
//查詢當前賬戶餘額
Double amount = accountService.getAmount(orderVO.getUserId());
logger.info("扣款前餘額: " + amount);
accountService.decreaseAccount(accountVO);
//查詢當前賬戶餘額
amount = accountService.getAmount(orderVO.getUserId());
logger.info("扣款後餘額: " + amount);
1. 測試用例 1
| 屬性 | 值 |
|---|---|
| 庫存 | 500 |
| 餘額 | 2000 |
| 商品編號 | C201901140001 |
| 用戶 | 1 |
結果：操作成功，庫存變成500，餘額變成2000，增加一個新訂單
