Spring Boot新手求助：REST消费控制台应用的Spring Initializer依赖选择

Hey there! Let's walk through exactly what you need to set up your Spring Boot project perfectly for your requirements.

Required Dependencies in Spring Initializer #

These are the must-have picks to cover all your core needs:

• Spring Boot Starter: This is the foundational dependency that gives you auto-configuration, core Spring functionality, and out-of-the-box logging support (via SLF4J + Logback) — so your logging requirement is already covered here!
• Spring Boot Starter WebClient: The official, lightweight HTTP client recommended by Spring for calling RESTful services. It supports both synchronous and asynchronous calls, and is far more flexible than the older RestTemplate. If you're more comfortable with RestTemplate, you can opt for Spring Boot Starter Web instead (it includes RestTemplate auto-config), but note that this will pull in web container dependencies which aren't strictly necessary for a console app.

For handling command-line arguments, you don't need an extra dependency! Spring Boot has built-in support via the CommandLineRunner or ApplicationRunner interfaces. Just implement one of them in a component, and you'll get access to the args passed when launching the JAR:

@Component
public class AppCommandLineHandler implements CommandLineRunner {
    @Override
    public void run(String... args) throws Exception {
        // Process your command-line arguments here
        System.out.println("Received arguments: " + Arrays.toString(args));
    }
}

Optional Libraries to Simplify Development #

These aren't mandatory, but they'll save you a ton of time and boilerplate:

• Lombok: A total game-changer for reducing repetitive code. Add annotations like @Data to your classes, and it automatically generates getters, setters, constructors, toString(), and more. You can search for it directly in Spring Initializer.
• Spring Boot Starter Validation: If you need to validate command-line arguments or REST request/response data, this lets you use annotation-based validation (like @NotNull, @Min, @Pattern) with minimal setup.
• Apache Commons CLI: For more complex command-line argument parsing (think flags like --input, --output, help menus, or argument aliases), this library takes the pain out of manually parsing the args array.
• Spring Boot Starter Actuator: Adds monitoring and management endpoints for your app — great for checking health status, adjusting log levels on the fly, or viewing metrics, which is super useful when maintaining scheduled tasks long-term.

One last note: Spring Boot's default build configuration will generate an executable JAR when you run mvn package (or ./gradlew bootJar for Gradle). You can launch it with java -jar your-app.jar arg1 arg2 to pass command-line arguments, which works perfectly for scheduled tasks.
