mysql连接超时：连接JAVA和Wampserver

1 月，3 周 Questions & Answers 187

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并抛出这个链接“192.168.1.88/PHPMyAdmin”，它工作正常，但我在NetBeans中遇到了一个超时错误，我尝试在PC和它之间ping工作正常

以下是堆栈跟踪：

以下是我的代码片段：

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");
        } 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);
         }
    }}
