问题描述
我正在尝试将 hibernate orm 映射工具配置到我的 java 类并使用 PostgreSQL 作为我的数据库并将密码配置为密码".当我尝试运行该应用程序时，我在控制台日志中遇到了错误无法创建请求的服务 [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment].我已经在旧版本的 hibernate 上尝试过这个，它奏效了.我现在使用的休眠版本是 5.1.0 版.
I am trying to configure hibernate orm mapping tool to my java class and using PostgreSQL as my database and configured the password as "password". When I tried to run the application, I have encountered error on my console logs as Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]. I have tried this on old version of hibernate and it worked. The hibernate version that I am using right now is version 5.1.0.

以下是我的hibernate.cfg.xml文件
The following is my hibernate.cfg.xml file
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC

我的 POJO 课
package org.javabrains.dto;
import javax.persistence.Entity;
@Entity
public class UserDetails {
private int userId;
private String userName;
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
}
还有我的应用类:
package org.javabrains.hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.javabrains.dto.UserDetails;
public class HibernateTest {
public static void main(String[] args) {
UserDetails user = new UserDetails();
user.setUserId(1);
user.setUserName("Tet");
//Hibernate API to save this objects to DB
//Session factory is created only ONCE
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
//create transaction
session.beginTransaction();
session.save(user);
//end the transaction
session.getTransaction().commit();
//Closing the session
session.close();
}
}

推荐答案
原因:由于hibernate无法连接到数据库而发生错误.
解决方案:
1. 请确保您在配置文件中提到的服务器上有一个数据库，例如.在这种情况下为hibernatedb".
2. 请查看连接数据库的用户名和密码是否正确.
3.检查连接所需的相关jar包是否映射到项目中.
Cause: The error occurred since hibernate is not able to connect to the database.
Solution:
1. Please ensure that you have a database present at the server referred to in the configuration file eg. "hibernatedb" in this case.
2. Please see if the username and password for connecting to the db are correct.
3. Check if relevant jars required for the connection are mapped to the project.
