无法创建请求的服务 [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]

Question

我正在尝试将休眠 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上尝试过这个并且它有效。我现在使用的休眠版本是 5.1.0 版。

以下是错误日志：

以下是我的hibernate.cfg.xml文件

我的 POJO 课程

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();
        
        
    }

}

Answer 1

原因：由于hibernate无法连接数据库而发生错误。
解决方法：
1. 请确保您在配置文件中引用的服务器上存在数据库，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是否映射到项目中。

Answer 2

您不需要hibernate-entitymanager-xxx.jar，因为您使用的是休眠会话方法（不是JPA）。您还需要关闭SessionFactory 并在出现错误时回滚事务。但是，问题当然不在于这些。

这是由数据库返回的

#
org.postgresql.util.PSQLException: FATAL: password authentication failed for user "sa"
#

您似乎提供了错误的用户名或（和）密码。

Answer 3

您遇到了数据库连接问题，或者您错过了任何用于连接数据库的休眠配置，例如数据库 DIALECT。

如果您的数据库服务器由于网络相关问题而断开连接，则会发生这种情况。

如果您使用 Spring Boot 以及连接到 Oracle Db 的休眠，请使用

hibernate.dialect=org.hibernate.dialect.HSQLDialect
hibernate.show_sql=true
hibernate.hbm2ddl.auto=update
hibernate.generate_statistics=true
entitymanager.packagesToScan: com

Answer 4

升级MySql驱动到Connector/Python 8.0.17或大于8.0.17，使用大于MySQL 5.5版本的人

Answer 5

我正在使用 Eclipse mars、Hibernate 5.2.1、Jdk7 和 Oracle 11g。

我在运行 Hibernate 代码生成工具时遇到了同样的错误。我想这是一个版本问题，因为我已经通过在我的 Hibernate 控制台配置的类型框中选择 Hibernate 版本（5.1 到 5.0）来解决它。

Answer 6

您忘记了 userId 上方的@ID

Answer 7

我遇到同样的错误并更改以下内容

SessionFactory sessionFactory =
    new Configuration().configure().buildSessionFactory();

到这里

SessionFactory sessionFactory =
    new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();

为我工作。

Answer 8

您必须停止另一个涉及特殊数据库表的正在运行的应用程序... 就像在其他模块或其他项目中运行java API没有终止..所以终止运行。

Answer 9

我在使用 MySQL 作为我的数据库时遇到了这个错误，唯一的解决方案是重新安装 MySQL 的所有组件，因为之前我只安装了服务器。

所以尝试下载其他版本的 PostgreSQL 并获取所有组件

Answer 10

在我的例子中，提供的用户名对数据库没有权限。授予权限已解决问题。
