要自定义SpringBoot CommandLine的启动逻辑,可以通过实现CommandLineRunner接口或ApplicationRunner接口来实现。

  1. 实现CommandLineRunner接口:
import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Component;

@Component
public class CustomCommandLineRunner implements CommandLineRunner {

    @Override
    public void run(String... args) throws Exception {
        // 在这里编写自定义的启动逻辑
        System.out.println("Custom command line runner is running...");
    }
}
  1. 实现ApplicationRunner接口:
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.stereotype.Component;

@Component
public class CustomApplicationRunner implements ApplicationRunner {

    @Override
    public void run(ApplicationArguments args) throws Exception {
        // 在这里编写自定义的启动逻辑
        System.out.println("Custom application runner is running...");
    }
}

这样,在SpringBoot应用启动时,会自动执行实现了CommandLineRunner或ApplicationRunner接口的类中的run方法,从而实现自定义的启动逻辑。
