spingboot異步接口開發

@SpringBootApplication
//開啓線程的註解
@EnableAsync 

public class PushServiceApplication {

    public static void main(String[] args) {
        new SpringApplicationBuilder(PushServiceApplication.class).run(args);
    }

}

之後建立一個類

package com.seckill.main.controller;

import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Component;

@Component 
public class AsyncTask {

  @Async  
  public void test2( ) throws InterruptedException{  
      long start = System.currentTimeMillis();  
      Thread.sleep(1000);  
      long end = System.currentTimeMillis();  
      System.out.println("test2");

  }  
  @Async  
  public void test3() throws InterruptedException{  
      long start = System.currentTimeMillis();  
      Thread.sleep(3000);  
      long end = System.currentTimeMillis();  
      System.out.println("test3");

  }  

}

之後是調用測試

@Autowired  
  private AsyncTask asyncTask;  


  @RequestMapping(value={"/test"})
  @ResponseBody
  public Object asyncTasktest() throws InterruptedException{
    int i=0;
    while(true) {  
      if(i>50){
        break;
      }
      asyncTask.test2();
      asyncTask.test3();
      i++;
      System.out.println(i);
      }
    System.out.println("結束");
    return "1";
  }

//總結 在方法上面不能定義成static 靜態的，不然就不會有異步的效果，第二就是不能有返回值，有的話，會報錯，一般就是給void 如定義一個方法：
