Java 方法里面 调用异步的 方法

package me.deweixu.aysncdemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableAsync;

@EnableAsync
@SpringBootApplication
public class AysncDemoApplication {

 public static void main(String[] args) {
  SpringApplication.run(AysncDemoApplication.class, args);
 }
}

@Service
public class AsynchronousService{
  @Async
  public void springAsynchronousMethod(){
    longTimeMethod();
  }
}

@Autowired
private AsynchronousService asynchronousService;

public void useAsynchronousMethod(){
  //我们需要执行的代码1
  asynchronousService.springAsynchronousMethod();
 //我们需要执行的代码2
}
