我在Symfony3中有一个依赖项注入的问题:
This is my services.yml
some_service:
class: StagingBundle'Service'SomeService
arguments: ['@doctrine']
arguments: ['@test.other_service']
这是SomeService.php的构造函数
public function __construct($doctrine, SomeService $someService)
{
$this->doctrine=$doctrine;
$this->someService=$someService;
}
当运行console命令时,我得到以下错误:
[Symfony'Component'Debug'Exception'ContextErrorException]
Catchable Fatal Error: Argument 2 passed to stagingBundle'Service'SomeService::__construct() must be an instance of StagingBundle'Service'OtherService, none given, called in /var/www/projects/myApp/var/cache/dev/appDevDebugProjectContainer.php on line 1141 and defined
为什么会发生这种情况,我该如何解决?
"arguments"是一个数组,只能出现一次,所以它应该是这样的
some_service:
class: StagingBundle'Service'SomeService
arguments: ['@doctrine', '@test.other_service']
