9 个解决方案

#1


連接超時..

#2


建議先不做業務連接數據庫試下!

#3


java.net.SocketException: java.net.ConnectException: Connection timed out: connect 

你目標的主機無法連接

#4


檢查一下
連接問題

具體是怎么連接的呢〉?

#5


檢查一下你連接數據庫的程序,看看是否配置正確,另需要看看要連接的數據庫能否正常使用啊

#6


檢查一下 createNewIO這個方法。

#7


數據庫連接配置是否正確

#8


 Connection timed out: connect 
數據庫那台機子可能跟你的機子網絡不通,或者數據庫已經當了..檢查一下具體原因吧
先檢查數據庫是否運行正常,再檢查網絡

#9


同錯,看看學習下
