oop - Hibernate SessionFactory -

-

क्यों हाइबरनेट के उदाहरणों को सत्रफ़ायर इंटरफ़ेस के बजाय SessionFactoryImpl वर्ग का उपयोग करें दिए गए कनेक्शन पर एक सत्र खोलें?

क्या कार्यान्वयन बदल सकता है? सामान्य तौर पर, यदि आप किसी ऑब्जेक्ट के साथ इंटरैक्ट करने के लिए इंटरफ़ेस का उपयोग कर सकते हैं, तो आपको चाहिए इंटरफेस कक्षाओं की तुलना में कम होने की संभावना है, इसलिए यदि कोई इंटरफ़ेस के अनुरूप हो, तो इंटरफ़ेस से हमेशा इसका संदर्भ दें। यह बहुत ही मानक ओओपी अभ्यास है।

php - Laravel - Overriding a resource route into a different route filter group -

-
Does Laravel's routing work as expected? What I think, if I want to override a route, then I just have to give the expected route before each other. I have something like this: root :: group (array ('first' = & gt; 'defaultLoads' =); function () {root :: post 'Newsletter', 'newsletter controller @ store'); root: group (array ('(newsletter', 'newsletter controller');}}); That if I post this route, only http://domain.com/newsletter should run only the default loads route filter. However, when I call php Runs artisan routes , I get this: | | POST newsletter | newsletter.store | newslettercontroller@ store | default loads | login | | though it reads the route correctly (PHP artisan loads which The correct path is to the right place) but the file of the resource path even if it is not in the filter group, the path is affected.
