Java 數據庫連接池問題?或者該怎麼提問才好?

    这是一个创建于 2729 天前的主题，其中的信息可能已经有所发展或是发生改变。

    今天寫程式的時候遇到一個問題, A.操作從數據庫獲取一條記錄, B.緊接著下一行代碼是向某服務器發送 post 請求 C.但是某種條件下可能出現對方服務器一直不回覆,導致程序一直卡在等待 post 的 response(為什麼不超時異常?我也很無奈啊) D.這種 情況下,導致 A 操作的連接池一直未釋放,最終在 druid 配置的 removeAbandoned timeout 內 maxActive 達到峰值,造成其他 dao 層一直等待連接池釋放. 從而導致程式卡死或者 500 這種情況那位大佬遇到過,怎麼處理?

    B 操作所依賴的數據必須來自 A ,而且 B 操作完畢的返回 post 數據也需要馬上使用到. 求解.

    下面貼異常信息,com.jh.pay 是我自己程序的 package,ctrl+F 可快速尋見:

    B 的锅。post 时候 timeout 和 retry 必须要想到。不然多少的连接池也架不住。
    不过如果业务上能变成异步处理，那就最好了。
    连接数是 tps x 平均响应时间吧。峰值连接数就是 峰值 tps x 峰值响应时间啦。你这峰值响应时间趋于无穷大怎么搞。

    利用 java FutureTask 类 强制设定超时时间 过了 多少秒 如果拿不到结果，就进行异常处理。

    A 和 B 应该是异步隔离，A 操作完成后，把数据发给 B 去处理，A 释放数据库连接；
    B 收到数据后发 post 请求，设置 socket 的读写超时时间，这样一直没有 response 的时候 B 会报错。
    A 和 B 要是多线程，线程之间可以通过消息通信。

    发送 post 的 httpClient 或者别的什么，设置合理的超时时间
    顺便，A 操作获取到结果后，数据库连接就应该已经还给连接池了
