Sql server Can'；t使用Hibernate连接到MS SQL Server 2008数据库实例

我正在尝试使用Hibernate连接到MSSQL服务器。当我尝试连接到“普通”数据库时，我编写的代码是可以的，但对于一个数据库，我总是会遇到异常，该数据库有实例

错误是：

使用相同的登录密码，I可以连接到数据库，但不能以编程方式，即使用sqlcmd

如何创建连接：

    public synchronized static SessionFactory getSessionFactory(Logger log, DbServer dbServer, String dbName) {

        String url = String.format("jdbc:sqlserver://%s:%d;databaseName=%s", dbServer.getServerName(), dbServer.getPort(), dbName);

        return new Configuration().configure()
            .setProperty("hibernate.connection.driver_class", "com.microsoft.sqlserver.jdbc.SQLServerDriver")
            .setProperty("hibernate.default_schema", "dbo")
            .setProperty("hibernate.dialect", "org.hibernate.dialect.SQLServerDialect")
            .setProperty("hibernate.connection.username", dbServer.getLogin())
            .setProperty("hibernate.connection.password", dbServer.getPassword())
            .setProperty("hibernate.connection.url", url)
            .buildSessionFactory();
    }

dbServer.getServerName（）

返回“serverName\dbInstance”，端口为1433，

dbName

为

master

。

使用Microsoft SQL Management Studio，我可以使用相同的登录名/密码进行连接，因此我很确定这是配置问题-我使用的是sys admin（sa），因此没有权限问题。

解决方案是在我尝试连接到数据库时不使用端口。因此，连接字符串如下所示：

String url = String.format("jdbc:sqlserver://%s;instanceName=%s;databaseName=%s", dbServer.getServerName(), dbServer.getInstanceName(), dbName);
