Question

我正在使用symfony版本3.4.8。配置适用于symfony 3.3，但在symfony 3.4中我得到：

Cannot autowire service "ProblemBundle\EntityManager\ProblemManager": argument "$paginator" of metho  
  d "__construct()" references interface "Knp\Component\Pager\PaginatorInterface" but no such service   
  exists. Did you create a class that implements this interface?

ProblemManager.php

public function (PaginatorInterface $page){}

应用程序/配置/ services.yml

# Learn more about services, parameters and containers at
# https://symfony.com/doc/current/service_container.html
parameters:
    #parameter_name: value

services:
    # default configuration for services in *this* file
    _defaults:
        # automatically injects dependencies in your services
        autowire: true
        # automatically registers your services as commands, event subscribers, etc.
        autoconfigure: true
        # this means you cannot fetch services directly from the container via $container->get()
        # if you need to do this, you can override this setting on individual services
        public: true

    # makes classes in src/AppBundle available to be used as services
    # this creates a service per class whose id is the fully-qualified class name
    # add more services, or override services that need manual wiring
    # AppBundle\Service\ExampleService:
    #     arguments:
    #         $someArgument: 'some_value'


    UserBundle\Controller\:
        resource: '../../src/UserBundle/Controller'
        public: true
        autowire: true
        tags: ['controller.service_arguments']

    UserBundle\EntityManager\UserManager:
        autowire: true

    ProblemBundle\EntityManager\ProblemManager:
        autowire: true
        public: true

如何为所有人（包括第三方捆绑包）配置自动装配？

Answer 1

指示您希望使用哪个实现的依赖注入组件，例如：

Knp\Component\Pager\PaginatorInterface:
    public: true
    alias: Your\Solid\Implementation

如果您想使用其他实现，则需要更改此单一配置行。

Answer 2

您仍然可以通过服务标签注入Non-Autowireable个参数，在您的情况下它将是

   ProblemBundle\EntityManager\ProblemManager:
    autowire: true
    public: true
    arguments:
        $page: "@knp_paginator.injectable"
