Question

我想将我的android项目连接到mysql JDBC上的我的数据库..我正在使用wampserver ...当我运行程序时我有这个错误

 Could not find class 'javax.naming.StringRefAddr', referenced from method com.mysql.jdbc.ConnectionPropertiesImpl$ConnectionProperty.storeTo
 W/System.err: java.sql.SQLException: null,  message from server: "Host 'widy-PC' is not allowed to connect to this MySQL server"

这是我的代码

public class Conexion {

    String classs = "com.mysql.jdbc.Driver";

    String url = "jdbc:mysql://localhost:3306/sanz";
    String un = "root";
    String password = "Kamasutra,27";
    @SuppressLint("NewApi")
    public Connection CONN() {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
                .permitAll().build();
        StrictMode.setThreadPolicy(policy);
        Connection conn = null;
        String ConnURL = null;
        try {

            Class.forName(classs).newInstance();

            conn = DriverManager.getConnection(url, un, password);


            conn = DriverManager.getConnection(ConnURL);
        } catch (SQLException se) {
            Log.e("ERRO", se.getMessage());
        } catch (ClassNotFoundException e) {
            Log.e("ERRO", e.getMessage());
        } catch (Exception e) {
            Log.e("ERRO", e.getMessage());
        }
        return conn;
    }

}

如果有人能帮助我，那将非常有用，非常感谢

我建议您的应用直接与数据库通信，您应该创建一个网络服务API来发送和接收从您的移动应用到Web服务API的数据。
