JVM Tomcat的春天MVC應用程序超時等待連接池

我的Tomcat上運行的Spring應用程序打開很多連接到本地主機這樣的：JVM Tomcat的春天MVC應用程序超時等待連接池

tcp6  1  0 localhost:4431   localhost:44178   CLOSE_WAIT 2393/java  
tcp6  1  0 localhost:4431   localhost:44279   CLOSE_WAIT 2393/java  
tcp6  1  0 localhost:4431   localhost:44264   CLOSE_WAIT 2393/java  
tcp6  1  0 localhost:4431   localhost:44160   CLOSE_WAIT 2393/java  
tcp6  1  0 localhost:4431   localhost:44224   CLOSE_WAIT 2393/java

並導致timeout waiting for connection pool.

你有一個想法是什麼連接可能是？

我server.xml看起來是這樣的：

端口4431是主要的連接器的端口。它看起來像應用程序自己調用。

您可能會打開連接，然後在完成操作後再關閉它們。追蹤所有的開放，並關閉它們。 – Compass

我不打開連接到本地主機。我使用的REST API非常慢，但API在另一臺服務器上運行。爲什麼有從本地連接到本地主機？ –

這不是你的數據庫的左側端口？你有沒有在tomcat的conf目錄中檢查'4431'？ –

看來你有一個SSL配置在Tomcat中不結束，那麼你可以爲4431端口完全刪除連接器，並用proxyPort取代8080連接器的redirectPort屬性=「443」

要弄清楚什麼是繼續在你的應用程序中，我會運行jconsole並查看它是什麼線程。它是Java SDK的一部分，它允許您查看在Tomcat中運行的線程。

我會試試看。 –
