host localhost port 3306 Unexpected response type:74

Because the online test database is closed, you need to use a local database

Note: The SQL Server database is used at work

After modifying the configured yml file, restarting the project reported an error

Internet search: tell me that the configuration file is wrong when connecting to mysql

But hey, I want to connect to the SQL Server database

Then I searched again, and then I looked through the yml configuration file of SQL Server to find that mysql and sql server are different in local configuration.

        driverClass: com.microsoft.sqlserver.jdbc.SQLServerDriver
        url: jdbc:sqlserver://localhost:1433;DatabaseName=数据库名
        username: sa
        password: 123456

The local port number of mysql is 3306

The local port number of sql server is 1433

I have been using mysql before, and the sql server I used after this project is because of my shallow knowledge.
