Java 不能'；t使用mysqlworkbench作为管理员从hibernate连接到mysql

我正在尝试通过hibernate连接到Mysql。我可以在mysqlworkbench中以管理员的身份创建数据库，但在尝试通过hibernate连接时，我遇到了以下错误

ERROR: Access denied for user 'root'@'localhost' (using password: YES)
Initial sessionfactory creationfailedorg.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]

Icustomer.java

package hibernate;

public interface ICustomer {
    public void addCustomer(Customer custDAO);


}

package hibernate;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="CUSTOMER")
public class Customer {
    @Id

    private int customerId;
    private String customerName;

    public Customer()
    {}
    public int getCustomerId() {
        return customerId;
    }
    public void setCustomerId(int customerId) {
        this.customerId = customerId;
    }
    public String getCustomerName() {
        return customerName;
    }
    public void setCustomerName(String customerName) {
        this.customerName = customerName;
    }
}

CustomerDAO.java

package hibernate;
import org.hibernate.Session;
import org.hibernate.Transaction;

public class CustomerDAO implements ICustomer
{

    @Override
    public void addCustomer(Customer custDAO) {
        // TODO Auto-generated method stub
        Session session=HibernateUtil.getSessionFactory().openSession();
        Transaction tx=session.beginTransaction();
        session.save(tx);
        tx.commit();
        session.close();

    }

}

Customer.java

package hibernate;

public interface ICustomer {
    public void addCustomer(Customer custDAO);


}

package hibernate;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="CUSTOMER")
public class Customer {
    @Id

    private int customerId;
    private String customerName;

    public Customer()
    {}
    public int getCustomerId() {
        return customerId;
    }
    public void setCustomerId(int customerId) {
        this.customerId = customerId;
    }
    public String getCustomerName() {
        return customerName;
    }
    public void setCustomerName(String customerName) {
        this.customerName = customerName;
    }
}

ClientDemo.java

package hibernate;
import java.util.Scanner;
import org.hibernate.HibernateException;
public class ClientDemo {
    public static void main(String[] args) {
        CustomerDAO custdao=new CustomerDAO();
        try
        {
            System.out.println("Create");
            System.out.println("Enter the data");
            Scanner sc=new Scanner(System.in);
            System.out.println("ID");
            int id=sc.nextInt();
            System.out.println("Name");
            String str=sc.next();
            Customer cust=new Customer();
            cust.setCustomerId(id);
            cust.setCustomerName(str);
            custdao.addCustomer(cust);
            System.out.println("One record created");
            sc.close();

        }
        catch (HibernateException e) {
            // TODO: handle exception
            System.out.println(e);
        }
    }
}

这是我的连接详细信息

数据库截图

jdbc:Mysql://127.0.0.1:3306/myschema

---

除了用户名和密码的正确性之外，您是否确定您的架构名称是

myschema

？另外，ysql中的大M可能是一个问题。

请注意，127.0.0.1与localhost for MySQL安全方案不同

---

尝试将hibernate.connection.url设置为localhost，或授予特定权限，例如（但不限于此示例）：

---

将**上的所有权限授予'root'@'127.0.0.1'
根用户没有此权限。所以通过下面的查询更改了权限

UPDATE mysql.user SET Grant_priv='Y', Super_priv='Y' WHERE User='root';
FLUSH PRIVILEGES;
GRANT ALL ON *.* TO 'root'@'localhost';

关闭我的连接并再次打开。
当在hibernate属性文件中传递的密码与数据库密码不匹配时，通常会出现此问题。请重新验证您的密码。您能否提供“用户”表的输出我在尝试运行上述10:21:41授予所有权限时出错。至“root”@“127.0.0.1”错误代码：1410。您不允许创建授予0.037秒权限的用户将hibernate.connection.url设置为localhost我收到相同的错误我相信您的根用户可能没有授予权限。请检查这个线程：是的，将Mysql更改为Mysql，是的，我的模式名是myschemado，数据库和应用程序服务器都在同一台机器上？
UPDATE mysql.user SET Grant_priv='Y', Super_priv='Y' WHERE User='root';
FLUSH PRIVILEGES;
GRANT ALL ON *.* TO 'root'@'localhost';
