Springboot項目如何異步提高接口的響應(yīng)速度

這篇文章主要介紹了Springboot項目如何異步提高接口的響應(yīng)速度方式,具有很好的參考價值,希望對大家有所幫助,如有錯誤或未考慮完全的地方,望不吝賜教

1、啟動類上添加開啟異步注解

@EnableAsync
public class Application {

2、編寫異步方法

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

import java.util.Random;
import java.util.concurrent.Future;

@Component
public class Task {

	public static Random random =new Random();

	@Async
	public Future<Long> doTaskOne() throws Exception {
		System.out.println("開始做任務(wù)一");
		long start = System.currentTimeMillis();
		Thread.sleep(random.nextInt(10000));
		long end = System.currentTimeMillis();
		return new AsyncResult<>(end-start);
	}
	@Async
	public Future<Long> doTaskTwo() throws Exception {
		System.out.println("開始做任務(wù)二");
		long start = System.currentTimeMillis();
		Thread.sleep(random.nextInt(10000));
		long end = System.currentTimeMillis();
		return new AsyncResult<>(end-start);
	}
	@Async
	public Future<Long> doTaskThree() throws Exception {
		System.out.println("開始做任務(wù)三");
		long start = System.currentTimeMillis();
		Thread.sleep(random.nextInt(10000));
		long end = System.currentTimeMillis();
		return new AsyncResult<>(end-start);
	}
}

3、執(zhí)行異步調(diào)用

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes=Application.class)
public class MainTester {

	@Resource
	private Task task;

	@Test
	public void test() throws Exception {
		long start = System.currentTimeMillis();

		Future<Long> task1 = task.doTaskOne();
		Future<Long> task2 = task.doTaskTwo();
		Future<Long> task3 = task.doTaskThree();
		Long res1 = task1.get();
		Long res2 = task2.get();
		Long res3 = task3.get();
		System.out.println("任務(wù)1完成耗時:"+res1);
		System.out.println("任務(wù)2完成耗時:"+res2);
		System.out.println("任務(wù)3完成耗時:"+res3);
		long end = System.currentTimeMillis();

		System.out.println("任務(wù)全部完成，總耗時：" + (end - start) + "毫秒");
	}

}
