# 新增asyncTask配置类 #

import org.springframework.context.annotation.Configuration;
    import org.springframework.scheduling.annotation.Async;
    import org.springframework.scheduling.annotation.EnableAsync;
    
    import java.util.concurrent.TimeUnit;
    
    /** * @author 张清赫 * Created by 2020-07-06 15:32 */
    @Configuration
    @EnableAsync
    public class AsyncTask { 
        @Async
        public void send(Integer params) { 
            //根据自己的逻辑进行操作,不影响调用方法的继续执行
            try { 
                TimeUnit.SECONDS.sleep(1000);
            } catch (InterruptedException e) { 
                e.printStackTrace();
            }
            System.out.println(params+"yesAsync");
    }

# 新增测试类 #

/** * @author 张清赫 * Created by 2020-08-24 */
    public class AsyncController(){ 
        @Resource
        private AsyncTask asyncTask;
        /** * 测试接口 */
        @GetMapping("/testAsync/{params}")
        public void testAsync(@Pathvariable Integer params){ 
            //调用异步任务
            asyncTask.send(params);
            System.out.println(params+"testAsync1");
            //调用非异步方法
            notAsyncTask(params);
            System.out.println(params+"testAsync2");
            //结果为: testAsync1
            // yesAsync
            // notAsync
            // testAsync2
        }
        //非异步方法
        public void notAsyncTask(Integer params){ 
           try { 
                TimeUnit.SECONDS.sleep(1000);
            } catch (InterruptedException e) { 
                e.printStackTrace();
            }
            System.out.println(params+"notAsync");
        }
