Question

我可以从我的mac上的虚拟操作系统（windows 8）连接到sqlserver，但我无法连接到mac上的sqlserver。

我的连接字符串如下所示。

server = (String) modelmain.getProp().getProperty("testserver1");
db = (String) modelmain.getProp().getProperty("testdb1");
user = (String) modelmain.getProp().getProperty("testuser1");
pass = (String) modelmain.getProp().getProperty("testpass1");

String getDatabaseJtdsUrl = "jdbc:jtds:sqlserver://" + server + "/" + db + ";";

我的变量如下所示。

server = "MyServer:1433"
db= "Mydb"
user = "dbuser"
pass = "userpassword"

我给用户名并传递hibernate的属性方法。顺便说一句，我使用休眠。

Configuration cfg = new Configuration();
cfg.setProperty("hibernate.connection.driver_class",
            "net.sourceforge.jtds.jdbc.Driver");
cfg.setProperty("hibernate.connection.url", getDatabaseJtdsUrl);
cfg.setProperty("hibernate.connection.username", user);
cfg.setProperty("hibernate.connection.password", pass);

如何在mac osx上使用jtds驱动程序连接到sqlserver？

错误如下。

Answer 1

试试这个

Configuration cfg = new Configuration()
        .addClass(org.hibernate.auction.Item.class)
        .addClass(org.hibernate.auction.Bid.class)
        .setProperty("hibernate.dialect","org.hibernate.dialect.SQLServerDialect")
         cfg.setProperty("hibernate.connection.driver_class",
            "net.sourceforge.jtds.jdbc.Driver");
         cfg.setProperty("hibernate.connection.url", getDatabaseJtdsUrl);
         cfg.setProperty("hibernate.connection.username", user);
         cfg.setProperty("hibernate.connection.password", pass);

然后你必须获得SessionFactory和JDBC连接

    SessionFactory sf = cfg.buildSessionFactory();
    Session session = sf.openSession();

您可以使用xml文件进行配置，请参阅此answer
