主要是設置的獲取事務時間內沒能獲取到對應的數據庫鎖導致事務提交失敗
具體的辦法：參見這篇博客https://blog.csdn.net/chuxue1989/article/details/85339160
第三步、解決方案
3.1臨時解決
通過 innodb_trx查找到等待的事務，kill +事務ID即可。
3.2緩解
減少高併發，或者調用接口先進入隊列，然後按照順序出兌這樣肯定能一定程度緩解這個問題。
將mysql的innodb_lock_wait_timeout時間加長
3.3代碼層面
主要原因還是代碼效率不高
分析發現接口interface1操作的更新表B沒有利用到索引，導致在百萬表中更新會特錶慢。
其實改接口是單一的，有事務和沒有事務都是一樣的，沒有說必須一起成功或者失敗的東西，去掉事務是可行的。
如果接口效率高了，但是併發量太大，還出現這個問題，我認爲這個時候就需要從設計層面考慮這個問題了，比如拆分表B等等。
另外關於@Tranctional失效
