spring boot 集成Async 注解 异步处理

有些时候 需要先返回数据 ，入库 以及其他操作可以异步去执行

定义一个task 任务类 ：

@Component
public class Task {
@Autowired
public RedisDao redisDao;

@Autowiredpublic UserOperatorService userOperatorService;@Asyncpublic void  AsyncTokenInfo(String token,JSONObject jsonObject) throws ParseException {    //提取手机号码 查询该用户是否存在    String phone = jsonObject.getString("phone");    Long user_id = 0L;    Long user_child_id = 0L;    //不存在则解析注册用戶    user_id =  userOperatorService.addOrUpdateUser(jsonObject);;    //注冊小孩 学生    user_child_id = userOperatorService.addUserChild(jsonObject, user_id, user_child_id);    //注册老师    userOperatorService.addUserTeacher(jsonObject, user_id);    //保存token的key    String ybbLoginPhone = RedisKeys.getRedisKey(RedisKeys.RootKey.ybbLoginPhone, phone);    boolean phone_exists = redisDao.exists(ybbLoginPhone);    if (phone_exists) {        String token_old = (String) redisDao.get(ybbLoginPhone);        String ybbLoginToken = RedisKeys.getRedisKey(RedisKeys.RootKey.ybbLoginToken, token_old);        redisDao.remove(ybbLoginToken);    }    JSONObject ybbJson = new JSONObject();    ybbJson.put("phone", phone);    ybbJson.put("user_id", user_id);    ybbJson.put("user_child_id", user_child_id);    redisDao.set(RedisKeys.getRedisKey(RedisKeys.RootKey.ybbLoginToken, token), ybbJson.toJSONString(), 24 * 60 * 60 * 30);    redisDao.set(ybbLoginPhone, token);}/***======================**///定义一个随机对象.public static Random random =new Random();@Async  //加入"异步调用"注解public void doTaskOne() throws InterruptedException {    System.out.println("开始执行任务一");    long start = System.currentTimeMillis();    Thread.sleep(random.nextInt(10000));    long end = System.currentTimeMillis();    System.out.println("完成任务一，耗时：" + (end - start) + "毫秒");}@Asyncpublic void doTaskTwo() throws InterruptedException {    System.out.println("开始执行任务二");    long start = System.currentTimeMillis();    Thread.sleep(random.nextInt(10000));    long end = System.currentTimeMillis();    System.out.println("完成任务二，耗时：" + (end - start) + "毫秒");}@Asyncpublic void doTaskThree() throws InterruptedException {    System.out.println("开始执行任务三");    long start = System.currentTimeMillis();    Thread.sleep(random.nextInt(10000));    long end = System.currentTimeMillis();    System.out.println("完成任务三，耗时：" + (end - start) + "毫秒");}

}

定义一个controller 调试这个task 或者写个单元测试

现在写个controller
@ResponseBody
@RequestMapping(“/task”)
public String task() throws Exception {
System.out.println(“开始执行Controller任务”);
long start = System.currentTimeMillis();
task.doTaskOne();
task.doTaskTwo();
task.doTaskThree();
long end = System.currentTimeMillis();
System.out.println(“完成Controller任务，耗时：” + (end - start) + “毫秒”);
return “success”;
}

通过访问 localhost:8088/task
多次执行 可以发现 想返回success
