尝试这个方法，它将在应用程序上下文完全启动时运行您的代码。

 @Component
public class OnStartServer implements ApplicationListener<ContextRefreshedEvent> {

    @Override
    public void onApplicationEvent(ContextRefreshedEvent arg0) {
                // EXECUTE YOUR CODE HERE 
    }
}

在春季> 4.1中使用SmartInitializingSingleton bean

@Bean
public SmartInitializingSingleton importProcessor() {
    return () -> {
        doStuff();
    };

}

作为备选方案，CommandLineRunner bean可以实现，也可以使用@PostConstruct注释bean方法。

你试过ApplicationReadyEvent吗?

@Component
public class ApplicationStartup 
implements ApplicationListener<ApplicationReadyEvent> {

  /**
   * This event is executed as late as conceivably possible to indicate that 
   * the application is ready to service requests.
   */
  @Override
  public void onApplicationEvent(final ApplicationReadyEvent event) {

    // here your code ...

    return;
  }
}

下面是文档中提到的启动事件:

... Application events are sent in the following order, as your application runs: An ApplicationStartedEvent is sent at the start of a run, but before any processing except the registration of listeners and initializers. An ApplicationEnvironmentPreparedEvent is sent when the Environment to be used in the context is known, but before the context is created. An ApplicationPreparedEvent is sent just before the refresh is started, but after bean definitions have been loaded. An ApplicationReadyEvent is sent after the refresh and any related callbacks have been processed to indicate the application is ready to service requests. An ApplicationFailedEvent is sent if there is an exception on startup. ...

“Spring Boot”方式是使用CommandLineRunner。只需添加该类型的bean，就可以了。在Spring 4.1 (Boot 1.2)中，也有一个SmartInitializingBean，它在所有东西初始化后得到一个回调。还有SmartLifecycle(来自Spring 3)。

为Dave Syer的回答提供了一个例子，这就像一个魅力:

@Component
public class CommandLineAppStartupRunner implements CommandLineRunner {
    private static final Logger logger = LoggerFactory.getLogger(CommandLineAppStartupRunner.class);

    @Override
    public void run(String...args) throws Exception {
        logger.info("Application started with command-line arguments: {} . \n To kill this application, press Ctrl + C.", Arrays.toString(args));
    }
}

为spring boot应用程序实现CommandLineRunner。 你需要实现run方法，

public classs SpringBootApplication implements CommandLineRunner{

    @Override
        public void run(String... arg0) throws Exception {
        // write your logic here 

        }
}
