集成@EnableAsync後出現問題的記錄

springboot 集成@EnableAsync後報錯

問題描述：

在集成@EnableAsync後項目無法啓動，出現下面的異常信息，在百度一番後說是依賴循環導致的，但未使用時沒有出現此問題 （項目中之前已使用@Async註解,但未使用@EnableAsync，所以之前的異步操作並未生效）

解決方式: 參考鏈接

1. 註釋掉全部@Async後測試是否能正常運行
2. 能夠正常啓動後再進行排查是由哪塊代碼引起,排除後即可正常運行
3. 可以定義異步處理Service類通過回調函數執行操作

同一個類調用另一個@Async的方法無法生效

解決方式:

將方法放到另一個Service再調用或者使用異步處理Service類通過回調函數執行操作

方法中聲明@Transactional和@Async註解,異步操作生效(打印當前線程信息可看)，但仍需等待線程執行完畢後返回結果（其中在測試過程中加了代碼段使其睡眠30s驗證是否存在此問題）

問題描述：

在controller調用的service中調用了其他service中的異步方法後，異步操作生效，但仍需等待異步操作線程執行完畢後才能返回結果(此時有將查詢的jpa對象傳入其他service中的異步方法)

解決方式:

1.可以將查詢和修改放在同一個異步方法操作
2.當前jpa環境下,仍使用原來的方式（實參爲查詢後的持久化對象），需要將當前查詢的持久化對象移除管理.
