連接超時：連接JAVA和Wampserver

我需要關於數據庫連接時間錯誤的幫助，我正在使用wamp服務器我可以訪問PHPMyAdmin拋出此鏈接「192.168.1.88/phpmyadmin」，它工作正常，但我得到一個超時在NetBeans錯誤，我試圖在PC之間的ping，它工作正常連接超時：連接JAVA和Wampserver

這裏是堆棧跟蹤：

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

    STACKTRACE:

這裏是我的代碼片段：

public class jdbcManager { 

    public HashMap<String, String> item = new HashMap<>(); 
    public static Connection conn; 
    private Statement s; 
    private ResultSet rs; 

    public jdbcManager() { 
     try { 
      Class.forName("com.mysql.jdbc.Driver"); 
     } catch (ClassNotFoundException ex) { 
      javax.swing.JOptionPane.showMessageDialog(null, "Erreur Driver ", "Etat de L'opération", javax.swing.JOptionPane.INFORMATION_MESSAGE); 
      Logger.getLogger(jdbcManager.class.getName()).log(Level.SEVERE, null, ex); 
     } 
     //=================================================================== 
     try { 
      conn = DriverManager.getConnection("jdbc:mysql://192.168.1.88:3306/agenceassurance", "root", "12345"); 
     } catch (SQLException ex) { 
      System.out.println(ex.getMessage()); 
      // javax.swing.JOptionPane.showMessageDialog(null, "Erreur Connection Base de donnée", "Etat de L'operation", javax.swing.JOptionPane.INFORMATION_MESSAGE); 
     } 
    }}

能請你寫準確，你得到了錯誤的單一數據庫的新用戶帳戶？ – Anubhav

嘗試ping此地址'ping 192.168.1.88' –

您是否正在運行與運行WAMPServer的計算機不同的計算機上的java代碼？ – RiggsFolly

當您試圖從遠程計算機連接到MySQL時，您需要在允許從遠程IP連接的MYSQL服務器上創建一個帳戶。

默認情況下，由於明顯的安全原因，root帳戶被設置爲僅允許從運行MySQL服務器的機器連接到MySQL服務器。

不改變這根被允許遠程連接創建一個只允許看你想連接到

我該如何實現這一目標？想給我舉個例子嗎？ – AbdeAMNR

多願意，但如何去實現什麼？ – RiggsFolly
