小编use*_*776的帖子

我正在开发的新应用程序正在使用Symfony2.没有数据库连接可供使用.相反,它建立在许多Web服务调用之上.在Symfony/app/config下,我想删除所有的database_*条目,但是当我这样做时,我得到一个

ParameterNotFoundException: You have requested a non-existent parameter "database_driver"

错误很明显.但是,如何从应用程序本身解耦和删除数据库配置？

我在Spring 3.1 MVC应用程序上遇到与HTTP Status 404类似的问题

但我没有像海报那样犯同样的错误,但我仍然得到404.

我能够加载index.jsp但不能加载实际的控制器.

我正在尝试从mysql加载User对象,但我一直收到UnboundExecutionError:无法找到在mapper Mapper | UserDo | user,SQL表达式或此Session上配置的绑定.我正在使用经典映射.

Base = declarative_base()

# A default constructor is created if one is not already present,
# which accepts keyword arguments of the same name as that of the mapped attributes.

class UserDo(Base):
    __tablename__ = 'user'

    id = Column(Integer, primary_key = True)
    fname = Column(String(100))
    lname = Column(String(100))
    email = Column(String(200))
    salt = Column(String(100))
    created_on = Column(TIMESTAMP) # from sqlalchemy.dialects.mysql import TIMESTAMP

class BaseService(object):

    def __init__(self):
        self._engine = create_engine('mysql://root@localhost/my_db', pool_recycle = 3600)
        self._Session = sessionmaker(bind …

我有这个目录结构:

.
??? controller
?   ??? FooController.py
?   ??? __init__.py
?
??? main.py

FooController:

from bottle import get, post, request, response, run, abort, \
                   redirect, LocalResponse
import json

@get('/')
def create():
    response.content_type = 'application/json'
    return json.dumps({'hello2' : 'world'})

我执行python main.py,其中包含:

from controller import *
from bottle import get, post, request, response, run, abort, \
                   redirect, LocalResponse

if __name__ == '__main__':
    run(host = 'localhost', port = 8080)

我希望通过导入所有控制器(在这种情况下FooController),它将挂钩到框架.但是当我去localhost时它不会:8080 /我收到404错误.如果我将所有路线都放入main.py,它就可以了.

有谁知道我怎么能完成我正在寻找的东西？
