在Module.php 加入配置方法
闭包方式:
public function getServiceConfig() {
    return array(
        'factories'=> array(
            'Test\A\B' => function($serviceManager) {
                return new B();
            },
        ),
    );
}
工厂类方式:
public function getServiceConfig() {
    return array(
        'factories'=> array(
            'Test\A\B' => 'Test\Service\TestFactory',
        ),
    );
}编写Test\Service\TestFactory
namespace Test\Service;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
class TestFactory implements FactoryInterface {/** _ Create custom_service _ _ @param ServiceLocatorInterface serviceLocator) { return $this; }
	/**
 	* @return string
 	*/
	public function test() {
    	return 'test';
	}
}在Controller调用
$this->getServiceLocator()->get('Test\A\B');
