java连接本机的sqlserver2008出现错误

Question

telnet 127.0.0.1 1433连接不上
telnet localhost 1433 能连上

com.microsoft.sqlserver.jdbc.SQLServerException: 通过端口 1433 连接到主机 localhost 的 TCP/IP 连接失败。错误:“Connection refused: connect。请验证连接属性。确保 SQL Server 的实例正在主机上运行，且在此端口接受 TCP/IP 连接，还要确保防火墙没有阻止到此端口的 TCP 连接。”。

Answer 1

Use the built-in client to connect and see

Answer 2

You first connect to your own sqlserver to see if it works, whether the IP is correct, and whether it is on a local area network! ! !
