java.sql.SQLException：访问拒绝用户'wineship'@'localhost'（使用密码：YES）

我搜索了类似的问题寻找解决我的问题的方法，因为很多人遇到同样的问题我。但是，没有任何解决方案能够提供帮助，而且我仍然有相同的错误堆栈。java.sql.SQLException：访问拒绝用户'wineship'@'localhost'（使用密码：YES）

这是我的java代码，开始连接。堆栈清楚地指出这行康恩=的DriverManager.getConnection（...）;:

package com.wine.plugins.managers.models; 

import java.sql.Connection; 
import java.sql.DriverManager; 
import java.sql.SQLException; 

public abstract class DatabaseModel 
{ 
    protected static Connection conn = null; 

    private static final String url = "jdbc:mysql://localhost/wineships?useSSL=false"; 
    private static final String username = "wineship"; 
    private static final String password = "password"; 

    public DatabaseModel() 
    { 
     try { 
      if(conn == null) 
      { 
       Class.forName("com.mysql.jdbc.Driver").newInstance(); 
       conn = DriverManager.getConnection(url, username, password); 
       if (conn != null) { 
        System.out.println("Connected to the database"); 
       } 
      } 
     } catch (SQLException e) { 
      e.printStackTrace(); 
      System.exit(0); 
     } catch (InstantiationException e) { 
      e.printStackTrace(); 
      System.exit(0); 
     } catch (IllegalAccessException e) { 
      e.printStackTrace(); 
      System.exit(0); 
     } catch (ClassNotFoundException e) { 
      e.printStackTrace(); 
      System.exit(0); 
     } 
    } 
}

这是堆栈：

您是否尝试过使用127.0.0.1呢？ –

确保你有一个用户'wineship'@'localhost'，它对你的数据库有必要的权限。 – suguspnk

也许你没有将用户称为'wineship'和密码作为'password'。用'root'作为用户，''“'（没有密码简单地打开和关闭双引号）作为密码。因为如果尚未配置用户名和密码，这些是默认的用户名和密码。 – Shashanth

我一直在修补phpmyadmin，我发现输入地址而不是使用'％'，解决了我的问题。我也改变了 “localhost” 的为127.0.0.1 @nigel仁

我的代码是现在：

private static final String url = "jdbc:mysql://127.0.0.1/wineships"; 
private static final String username = "wineship"; 
private static final String password = "password";
