如何仅从main方法写入日志

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Main {
    private static final Logger logger = LoggerFactory.getLogger(Main.class);

    public static void main(String[] args) {
        // 打印日志信息
        logger.info("This is a log message.");

        // 打印带参数的日志信息
        String name = "John";
        logger.info("Hello, {}!", name);
    }
}

import java.util.logging.Logger;

public class Main {
    private static final Logger logger = Logger.getLogger(Main.class.getName());

    public static void main(String[] args) {
        // 打印日志信息
        logger.info("This is a log message.");

        // 打印带参数的日志信息
        String name = "John";
        logger.info("Hello, {}!", name);
    }
}

public class Main {
    public static void main(String[] args) {
        // 打印日志信息
        System.out.println("This is a log message.");

        // 打印带参数的日志信息
        String name = "John";
        System.out.println("Hello, " + name + "!");
    }
}
