Difference between a Factory, Provider and a Service?

---

Factory: Assembles classes, either by composing a bunch of bits together, or choosing type based on some kind of context

Provider: Provider is something microsoft "invented" (basically an abstract factory pattern) that is a way of doing a factory of factories, or having a common factory interface which allows factories to be swappable. It is used all over in the MS web stack as a way to keep components configurable.

Service: A service is a group of related functionality. Think of it as if you are splitting your architecture horizontally, you have a "Business Logic" layer, if you split that vertically you will have services.

How To Install Maven

Maven Central Repository は、現在、TLSv1.2でないと接続できなくなりました。

JDK1.7（を含めて）以前のバージョンで、Mavenビルドを実行している環境では、デフォルトでは、JDKがTLSv1.2をサポートしていないため、以下のようなエラーが発生していることと思います。

Received fatal alert: protocol_version -> [Help 1]
