Excuse me, is it possible to connect to sqserver2012 in Spring Boot version 1.5.21 without upgrading to Spring Boot? However, when Spring Boot version 1.5.21 matches mssql-jdbc -9.2.1jre11, it prompts' overlapping managed version 6.1.0.jre7 for mssql-jdbc ' If it is necessary to upgrade Springboot to connect to SQL Server 2012, what version is the official recommendation for upgrading to?

As stated in #38629, Spring Boot 1.5 has been out of support for many years now. As mentioned in the guidelines for contributing, we prefer to use GitHub issues only for bugs and enhancements, and we can't spend our time answering questions about versions that are out of support. Please post your questions to Stack Overflow.

The connection has been successful, it is a problem with the database server settings. Thank you all for your enthusiastic help.
