java - 无法在远程系统上使用 Windows 身份验证连接到 MS sql 服务器

Question

我试图连接到安装在远程系统上的 ms sql server 2008。但它显示错误。以下是我尝试过的方法

import java.io.File;
import java.sql.Connection;  
import java.sql.DriverManager;  
import java.sql.PreparedStatement;
import java.sql.ResultSet;  
import java.sql.Statement;  


public class mssql {  
    public static void main(String[] args) {  
        try {  
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();

            Connection connection=DriverManager.getConnection("jdbc:sqlserver://192.168.1.220:1433;databaseName=sales;integratedSecurity=true;");
            if(!(connection==null))
            {
                System.out.println("connected");
            }

//            


        } catch (Exception e) {  
            e.printStackTrace();  
        }  
    }  
}  

这是我遇到的错误

com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host 192.168.1.220, port 1433 has failed. Error: "connect timed out. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".

此问题的任何解决方案

Answer 1

2008 SQL 实例是否配置为监听 TCP 连接？

开始、Microsoft SQL Server 2008、配置工具、SQL Server 配置管理器SQL Server 网络配置
[实例名称]
的协议(protocol)应列出四项:

• 共享内存
• 命名管道
• TCP/IP
• 威盛

对于您的环境，哪些应该启用，哪些应该禁用？大多数设置要求启用共享内存和 TCP/IP，而其他设置则禁用。
