This can be very useful for setting up **resources** that you need to use for the whole app, and that are **shared** among requests, and/or that you need to **clean up** afterwards. For example, a database connection pool, or loading a shared machine learning model.

## Use Case { #use-case }

Let's start with an example **use case** and then see how to solve it with this.

        // Create temporary directory structure for SMB shares
        tempDir = Files.createTempDirectory("smbtest");
        setupTestDirectoryStructure();

        // Configure SMB context and connection URL
        String host = sambaContainer.getHost();
        Integer port = sambaContainer.getMappedPort(SMB_PORT);
        baseUrl = "smb://" + host + ":" + port + "/";

/// tip

Additionally, a background task is normally an independent set of logic that should be handled separately, with its own resources (e.g. its own database connection).

So, this way you will probably have cleaner code.
