2, com. Microsoft. Essentially. JDBC. SQLServerException: The TCP/IP connection to The host localhost, 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 has The TCP/IP connections at The port. Make sure that TCP connections to The port are not blocked by a firewall.".

The first question: C: \ Users \ LENOVO \. M2 \ repository \ com \ sun \ XML bind folder to delete, and then in pom. Plus the following configuration in XML, to update the project
