问题描述

我的 sql 服务器实例名称是 MYPCSQLEXPRESS，我正在尝试创建一个 jTDS 连接字符串来连接到数据库博客".任何人都可以帮我完成那个吗?

my sql server instance name is MYPCSQLEXPRESS and I'm trying to create a jTDS connection string to connect to the database 'Blog'. Can anyone please help me accomplish that?

我正在尝试这样做:

DriverManager.getConnection("jdbc:jtds:sqlserver://127.0.0.1:1433/Blog", "user", "password");

我明白了:

 java.sql.SQLException: Network error IOException: Connection refused: connect

    at net.sourceforge.jtds.jdbc.ConnectionJDBC3.<init>(ConnectionJDBC3.java:50)

推荐答案

详见 jTDS Frequenlty问的问题，jTDS的URL格式为:

As detailed in the jTDS Frequenlty Asked Questions, the URL format for jTDS is:

jdbc:jtds:<server_type>://<server>[:<port>][/<database>][;<property>=<value>[;...]]

因此，要连接到由运行在 MYPC 上的 MS SQL Server 托管的名为Blog"的数据库，您可能会得到如下结果:

So, to connect to a database called "Blog" hosted by a MS SQL Server running on MYPC, you may end up with something like this:

jdbc:jtds:sqlserver://MYPC:1433/Blog;instance=SQLEXPRESS;user=sa;password=s3cr3t

或者，如果您更喜欢使用 getConnection(url, "sa", "s3cr3t"):

Or, if you prefer to use getConnection(url, "sa", "s3cr3t"):

jdbc:jtds:sqlserver://MYPC:1433/Blog;instance=SQLEXPRESS

关于您的 Connection denied 错误，请仔细检查您是否在端口 1433 上运行 SQL Server，该服务是否正在运行并且您没有阻止传入连接的防火墙.

Regarding your Connection refused error, double check that you're running SQL Server on port 1433, that the service is running and that you don't have a firewall blocking incoming connections.
