Java Hibernate SQL Server表达连接错误

Question

Trying to connect my Java Spring app on Tomcat to my sqlserver express database with Hibernate.

Getting error:

com.microsoft.sqlserver.jdbc.SQLServerException: Connection Failed TCP / IP to localhost port 1433.
Error: "Connection refused: connect. Check the connection properties, make
sure that an instance of SQL Server is running on the host and accepting TCP
/ IP connections to port, and make sure that no firewall is blocking TCP 
connections to port. ".

Answer 1

问题是您的tcp / ip协议不是1433，请按照以下说明操作，您的问题应该消失了：SqlServer配置管理器> Sql服务器网络配置> SQLEXPRESS的协议>右键单击TCP / IP>属性> IP地址> IPALL并将TCP PORT更改为1433

Answer 2

in majority of cases its the firewall that blocks it. try disabling it
