这是我的cfg.xml文件:
<!-- Database connection settings -->
<property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
<property name="connection.url">jdbc:sqlserver://localhost:1433;DatabaseName=hiber;</property>
<property name="connection.username">Costi-PC\Costi</property>
<property name="connection.password"></property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">create</property>
<!-- Names the annotated entity class -->
<mapping class="model.User" />
用户类和主类:
@Entity
public class User {
@Id
private int userId;
private String userName;
public int getUserId() {..}
public void setUserId(int userId) {..}
public String getUserName() {..}
public void setUserName(String userName) {..}
}
public class Main {
public static void main(String[] args) {
User user = new User();
user.setUserId(1);
user.setUserName("Costi");
AnnotationConfiguration configuration = new AnnotationConfiguration();
configuration.configure();
SessionFactory sessionFactory = configuration.buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
session.save(user);
session.getTransaction().commit();
session.close();
sessionFactory.close();
}
当我运行程序时,我收到此错误:

我正在使用sql server 2008。 我尝试了不同类型的cfg配置,但似乎都没有。 我相信问题来自connection.url。我试图更改端口(1433),但没有。 谁能说出问题是什么?

我知道这篇文章差不多有两年了,但对我而言,问题给了我正确答案。因为有相同问题的人会从Google收到这篇文章。我想,让我们添加我的故事。
同样的问题,同样的问题。对我来说,答案是SQL Server不接受来自外部的连接。 tcp / ip网络客户端配置是标准禁用的。
所以这对我来说是朝着正确方向的暗示。

至8.0.19
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.19</version>
</dependency>
对我有用。 谢谢。

尝试转到命令行,查看sqlserver是否确实正在侦听该端口。在Windows上,这将是命令:
netstat -nao | findstr 1433
然后在Windows(Ctr + Alt + Delete)进程列表中查看PID是否是预期的SQL Server。
如果服务器正在运行,请尝试使用SQL客户端GUI连接到它,请参阅此处examples。如果可以从外部客户端成功连接到数据库,请再次从Java程序中重试。
尝试查看本地防火墙设置是否可以查看防火墙是否是导致错误的原因,尽管默认情况下防火墙不会阻止localhost - 请查看此answer。

从jTDS1.2.8迁移到mssql-jdbc时出现相同的错误,对我来说,这有助于删除端口号并在hibernate.cfg.xml中的连接URL中指定命名实例
发件人:
<property name="hibernate.connection.url">jdbc:sqlserver://MYHOSTNAME:1433;databaseName=mydbname;instanceName=MYINSTANCENAME;</property>
收件人:
<property name="hibernate.connection.url">jdbc:sqlserver://MYHOSTNAME;instanceName=MYINSTANCENAME;databaseName=mydbname;</property>
参考:https://docs.microsoft.com/en-us/sql/connect/jdbc/building-the-connection-url?view=sql-server-2017
使用命名和多个SQL Server实例时,要使用JDBC URL属性,请执行以下操作:
jdbc:sqlserver://localhost;instanceName=instance1;integratedSecurity=true;<more properties as required>;
