When connecting to the database in idea, it prompts inStream parameter is null error

It is said on the Internet that a bunch of properties database configuration files are not placed under src. The main problem is the placement of configuration files. In the old version, inStream parameter is null is placed under src, but it cannot be placed directly in the new version of IDEA. The src directory is below, the location should be in src/main/resources, if not, right click src new one.

That'll be fine!
