Python flask无法正常启动celery任务队列出现什么问题了，flaskcelery,最近在写一个flask应

最近在写一个flask应用,想使用celery做任务队列,就去flask官网上找了样例程序,然后复制到本机上执行了一下,结果celery没有正常启动.
只有一个源文件test.py,rabbitmq已配置并正常启动.
代码如下:

from flask import Flaskfrom celery import Celerydef make_celery(app):    celery = Celery(app.import_name, broker=app.config['CELERY_BROKER_URL'], backend=app.config['CELERY_RESULT_BACKEND'])    celery.conf.update(app.config)    TaskBase = celery.Task    class ContextTask(TaskBase):        abstract = True        def __call__(self, *args, **kwargs):            with app.app_context():                return TaskBase.__call__(self, *args, **kwargs)    celery.Task = ContextTask    return celeryapp = Flask(__name__)app.config.update(        CELERY_BROKER_URL='amqp://guest@localhost//',        CELERY_RESULT_BACKEND='amqp://guest@localhost//')celery = make_celery(app)@celery.task()def add_together(a, b):    return a + bresult = add_together.delay(23, 42)result.wait()   

差不多就是样例代码直接拷贝下来用了.
然后我在当前目录下执行celery -A test worker --loglevel=info和celery -A test.celery worker --loglevel=info之后阻塞,同时没有任何提示.
我另外打开一个终端,在这个目录下执行python test.py之后发生阻塞.用pdb调试发现阻塞在最后一行result.wait().
请问我的配置过程出现什么问题了?

# coding: utf-8from celery import Celeryfrom flask import Flaskdef make_celery(app):    celery = Celery(app.import_name, broker=app.config['CELERY_BROKER_URL'], backend=app.config['CELERY_RESULT_BACKEND'])    celery.conf.update(app.config)    TaskBase = celery.Task    class ContextTask(TaskBase):        abstract = True        def __call__(self, *args, **kwargs):            with app.app_context():                return TaskBase.__call__(self, *args, **kwargs)    celery.Task = ContextTask    return celeryapp = Flask(__name__)app.config.update(        CELERY_BROKER_URL='amqp://guest@localhost//',        CELERY_RESULT_BACKEND='amqp://guest@localhost//')celery = make_celery(app)@celery.task(name='add_together')def add_together(a, b):    return a + bif __name__ == '__main__':  result = add_together.delay(23, 42)  result.wait()
