标签： java hibernate postgresql jdbc orm

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“password”。当我尝试运行应用程序时，我在控制台日志上遇到错误  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：

原因：由于hibernate无法连接到数据库，因此发生错误 的解决方案：的
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。

答案 1 :(得分：9)

您不需要hibernate-entitymanager-xxx.jar，因为您使用的是Hibernate会话方法（不是JPA）。您还需要关闭SessionFactory并在错误上回滚事务。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名或（和）密码。

答案 2 :(得分：3)

您遇到数据库连接问题，或者错过了任何休眠配置来连接数据库，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

。

如果您正在使用Spring Boot以及与Oracle Db连接的休眠模式，请使用

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

答案 3 :(得分：0)

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

运行Hibernate代码生成工具时出现同样的错误。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。

答案 4 :(得分：0)

您忘记了userId

上方的@ID

答案 5 :(得分：0)

我收到了同样的错误并更改了以下内容

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

到这个

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

为我工作。

答案 6 :(得分：0)

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... 比如在其他模块中运行java API或其他项目没有终止..所以终止运行。

答案 7 :(得分：0)

我在使用MySQL作为数据库时遇到此错误，唯一的解决方法是重新安装MySQL的所有组件，因为在我仅安装服务器之前。

因此，请尝试下载其他版本的PostgreSQL并获取所有组件

答案 8 :(得分：0)

将MySql驱动程序升级到Connector / Python 8.0.17，正在使用 greater than MySQL 5.5 版本的人
