Spring Boot任务管理之有返回值异步任务调用

https://www.cnblogs.com/my-program-life/p/12047396.html  Spring Boot任务管理之无返回值异步任务调用

一、在OwnAsynService基础上添加

 

 

复制代码
package com.uos.schedule.service;
import org.springframework.scheduling.annotation.Async;
import org.springframework.scheduling.annotation.AsyncResult;
import org.springframework.stereotype.Service;
import java.util.concurrent.Future;
@Service
public class OwnAsynService {
    @Async
    public void sendSMS() throws InterruptedException{
        System.out.println("调用短信验证服务方法");
        Long startTime = System.currentTimeMillis();
        Thread.sleep(5000);
        Long endTime=System.currentTimeMillis();
        System.out.println("短信业务执行消耗完成时间:\t"+(endTime-startTime));
    }
    @Async
    public Future<Integer> processA() throws InterruptedException {
        System.out.println("开始分析并统计业务A数据......");
        Long startTime = System.currentTimeMillis();
        Thread.sleep(4000);
        int count = 123456;
        Long endTime = System.currentTimeMillis();
        System.out.println("业务A数据统计消耗时间:\t" + (endTime - startTime));
        return new AsyncResult<>(count);
    }
    @Async
    public Future<Integer> processB() throws InterruptedException {
        System.out.println("开始分析并统计业务B数据......");
        Long startTime = System.currentTimeMillis();
        Thread.sleep(5000);
        int count = 456789;
        Long endTime = System.currentTimeMillis();
        System.out.println("业务B数据统计消耗时间:\t" + (endTime - startTime));
        return new AsyncResult<>(count);
    }

}

二、在OwnAsynController基础上添加

 

 

复制代码
package com.uos.schedule.controller;

import com.uos.schedule.service.OwnAsynService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.concurrent.ExecutionException;
import java.util.concurrent.Future;

/**
 *控制层
 */
@RestController
public class OwnAsyncController {
    @Autowired
    private OwnAsynService ownAsynService;

    @GetMapping(value = {"sendSMS"})
    public String sendSMS() throws InterruptedException {
        Long startTime = System.currentTimeMillis();
        ownAsynService.sendSMS();
        Long endTime = System.currentTimeMillis();
        System.out.println("主业务执行消耗完成时间:\t" + (endTime - startTime));
        return "success";
    }
    @GetMapping(value = {"statics"})
    public String statics() throws InterruptedException, ExecutionException {
        Long startTime = System.currentTimeMillis();
        Future<Integer>futureA=ownAsynService.processA();
        Future<Integer> futureB=ownAsynService.processB();
        int total=futureA.get()+futureB.get();
        System.out.println("异步任务数据统计汇总结果:\t"+total);

        Long endTime = System.currentTimeMillis();
        System.out.println("主业务执行消耗完成时间:\t" + (endTime - startTime));
        return "success";
    }
}
