当我执行我的主类时，我得到这个执行无法找出问题点
错误出现在 Transaction tr = session.beginTransaction();
错误堆栈说：
ERROR: Access denied for user 'root'@'localhost' (using password: NO)
error===>org.hibernate.exception.GenericJDBCException: Could not open connection
我的主类文件：
package com.hussi.model;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
public class Main {
public static void main(String[] args)
{
User user = new User();
user.setUser_id(1);
user.setUsername("hussi");
user.setPassword("maria");
SessionFactory sesionFactory = new Configuration().configure().buildSessionFactory() ;
Session session = sesionFactory.openSession();
try{
Transaction tr = session.beginTransaction();
session.save(user);
}
catch(Exception e)
{
System.out.println("error===>"+e);
}
finally
{
session.flush();
session.close();
}
}
}
我的模型文件
package com.hussi.model;
public class User
{
int user_id;
String username;
String password;
public int getUser_id() {
return user_id;
}
public void setUser_id(int user_id) {
this.user_id = user_id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String toString()
{
return "username==>"+this.username+" : password==>"+this.password;
}
}
