无法创建请求的服务

我正在尝试将hibernate orm映射工具配置为java类并使用PostgreSQL作为我的数据库并将密码配置为“密码”。 当我尝试运行应用程序时，我在控制台日志中遇到了这种错误。 无法创建请求的服务[org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]。 我在旧版本的hibernate上试过这个并且它有效。 我现在使用的hibernate版本是5.1.0版。

以下是错误日志：

以下是我的hibernate.cfg.xml文件

      org.postgresql.Driver jdbc:postgresql://localhost:5432/hibernatedb sa password  1  org.hibernate.dialect.PostgreSQLDialect  thread  org.hibernate.cache.internal.NoCacheProvider  true  create     

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; } } 

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

你不需要hibernate-entitymanager-xxx.jar ，因为你使用的是Hibernate会话方法（不是JPA ）。 您还需要关闭SessionFactory并回滚错误事务。 但是，问题当然不是那些问题。

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或（和）密码。

Answer 2

原因：由于hibernate无法连接到数据库，因此发生错误。
解：
1.请确保您在配置文件中引用的服务器上有一个数据库，例如。 在这种情况下，“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。

Answer 3

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

我运行Hibernate代码生成工具时遇到同样的错误。 我想这是一个版本问题，因为我通过在Hibernate控制台配置中的类型框架中选择Hibernate版本（5.1到5.0）来解决它。

Answer 4

你忘记了userId上面的@ID

Answer 5

你必须停止涉及特殊数据库表的另一个正在运行的应用程序…就像在其他模块中运行java API或其他项目没有终止..所以终止运行。

Answer 6

我得到了同样的错误并改变了以下内容

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

对此

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

为我工作。
