SpringBoot启动后，执行初始化方法

介绍

spring boot项目，有时我们希望在项目启动的时候，执行一些初始化方法，以下介绍几种实现方式

示例

1. CommandLineRunner

@Component
public class MyCommandLineRunner implements CommandLineRunner {
    
    
    @Override
    public void run(String... args) throws Exception {
    
    
        System.out.println("我来自：CommandLineRunner");
    }
}

2. ApplicationRunner

@Component
public class MyApplicationRunner implements ApplicationRunner {
    
    
    @Override
    public void run(ApplicationArguments args) throws Exception {
    
    
        System.out.println("我来自：ApplicationRunner");
    }
}

3. PostConstruct

@Configuration
public class MyPostConstruct {
    
    
    @PostConstruct
    public void init() {
    
    
        System.out.println("我来自：PostConstruct");
    }
}

4. EventListener

@Configuration
public class MyEventListener {
    
    
    @EventListener
    public void init(ContextRefreshedEvent event) {
    
    
        System.out.println("我来自：EventListener");
    }
}
