某客戶：你們的監控軟件連接不上我們的后台數據庫了，報超時了，請問超時時間怎樣設置的？
某人：你們用的是那個數據庫的？
某客戶：
Exception message: Could not create connection; - nested throwable: (com.microsoft.sqlserver.jdbc.SQLServerException:
The TCP/IP connection to the host XXXX, port 1433 has failed.
Error: "connect timed out. Verify the connection properties, check that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port,
and that no firewall is blocking TCP connections to the port.".);
- nested throwable: (org.jboss.resource.JBossResourceException: Could not create connection;
- nested throwable: (com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host XXXX, port 1433 has failed. Error: "connect timed out.
Verify the connection properties, check that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port, and that no firewall is blocking TCP connections to the port.".))
某人：這是mssql server 數據庫的。
某人看了一下報錯，發現是連接根本創建不了，不別提超時了。
某人：你們是不是做了什么更改了？
某客戶：是啊，我們對數據庫做了一些調整，然后就出現這問題了。
某人：好像是TCP/IP請求給阻擋住了，你要查一下是不是 TCP/IP協議給禁止了。點擊“SQL Server Configuration Manager" -> "SQL Server XXX Network Configuration -> Protocols for MSSQL SERVER -> TCP/IP，如果是被禁止了，就啟動一下。
某客戶：好的，我們試一下。
