我有一个spring boot应用程序,想通过使用@async annotation运行一个简单的异步后台任务,但是,这似乎不起作用(没有创建新线程,我要等到每次调用函数后睡眠结束。
*****我的配置类:**
@Configuration
@EnableAsync
public class AsyncConfig {
}
****我的控制器:***
@GetMapping(value = "/testAsync")
@ResponseBody
public String testAsync() {
TestClass testClass = new TestClass();
System.out.println("begin of test async dates is : " + new Date());
for (int i = 0; i < 5; i++) {
testClass.asyncMethod();
}
System.out.println("end of test async dates is : " + new Date());
return "end!";
}
*****我的testClass中的异步方法:**
@Service
public class TestClass {
@Async
public void asyncMethod() {
System.out.println("Execute method asynchronously. in thread : "
+ Thread.currentThread().getName());
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("after sleep : " + Thread.currentThread().getName());
}
}
****运行应用程序后输出:**
begin of test async dates is : Sat Jul 14 19:35:43 EET 2018
Execute method asynchronously. in thread : http-nio-8080-exec-1
after sleep : http-nio-8080-exec-1

****注:**
-我试过用@component注释testclass,但它不起作用
-我尝试在应用程序级别和方法级别都添加一个执行器,但得到的结果相同。
请帮帮我,我花了5个小时在这件事上,运气不好
