Spring Boot new version i.e. 4.0.4

Body

In the latest version of Spring Boot, do we have an in-built graceful shutdown? There's one issue in the latest version, and that is the connectivity of MongoDB Compass via application.properties. I guess there's a version mismatch, which causes data not to be saved in the new database and gets saved into the default database named test. All dependencies are downloaded through the official site, which is start.spring.io.

Yes, you can enable graceful shutdown in your application.properties with:

Properties
server.shutdown=graceful
Regarding the MongoDB issue: It’s not a version mismatch. In Spring Boot 4.x, the configuration prefix was changed. Your app is defaulting to the test database because it doesn't recognize the old property keys.

How to fix it:
Just remove the .data part from your MongoDB properties:

Change: spring.data.mongodb.uri

To: spring.mongodb.uri

Once you update the prefix, Spring will correctly pick up your custom database name.

Yes, graceful shutdown is already built into Spring Boot. In current Spring Boot docs, it’s enabled by default for embedded web servers, so that part does not need custom handling.

For MongoDB, the usual fix is to make sure the database name is included in spring.data.mongodb.uri, otherwise MongoDB can fall back to the default test database. The Spring docs still use the spring.data.mongodb prefix, so switching to spring.mongodb.uri is not the right fix here.

Example:
spring.data.mongodb.uri=mongodb://localhost:27017/yourDatabaseName

Also, this is more of a Spring Boot / MongoDB question than a GitHub issue.
