Spring-boot: 容器启动后执行指定方法

Spring-boot给我们提供了两种在容器启动后执行指定方法的接口: ApplicationRunner和CommandLineRunner.

• CommandLineRunner: 通过字符串数组接收参数
• ApplicationRunner: 通过ApplicationArguments 接收参数

示例:

@Component
@Order(value = 1) // 决定各个Runner的执行次序
public class MyCommandLineRunner implements CommandLineRunner{
  @Override
  public void run(String... var1) throws Exception{
    // do something
  }
}

@Component
@Order(value = 2) // 决定各个Runner的执行次序
public class MyApplicationRunner implements ApplicationRunner{
  @Override
  public void run(ApplicationArguments var1)   throws Exception{
    // do something
  }
}
