我需要关于数据库连接时间错误的帮助，我正在使用wamp服务器我可以访问PHPMyAdmin抛出此链接“192.168.1.88/phpmyadmin”，它工作正常，但我得到一个超时在NetBeans错误，我试图在PC之间的ping，它工作正常连接超时：连接JAVA和Wampserver

这里是堆栈跟踪：

这里是我的代码片段：

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");

能请你写准确，你得到了错误的单一数据库的新用户帐户？ – Anubhav

尝试ping此地址'ping 192.168.1.88' –

您是否正在运行与运行WAMPServer的计算机不同的计算机上的java代码？ – RiggsFolly

当您试图从远程计算机连接到MySQL时，您需要在允许从远程IP连接的MYSQL服务器上创建一个帐户。

默认情况下，由于明显的安全原因，root帐户被设置为仅允许从运行MySQL服务器的机器连接到MySQL服务器。

不改变这根被允许远程连接创建一个只允许看你想连接到
