Spring DATA JPA概要

Spring DATA JPA

はじめに

  • Spring DATA JPAは、Spring Frameworkの拡張ライブラリ。springframework-jdbcシリーズか springframework-ormシリーズのようだが、安定したら本流に組み込まれるのかもしれない。
  • この記事の執筆時点のバージョンは SPRING DATA JPA 1.1.0 GA
  • Spring DATA JPAは、JPAの機能をベースに 汎用的な Repositoryの機能を提供する。
  • ちなみに、Repositoryというのは、ドメイン駆動設計（Domain Driven Design)のパターンのひとつで、ドメインのEntityのCollectionのように振舞う責務を持つ。例えば CustomerRepositoryならば、システムに存在するCustomer EntityたちをCollectionに保持するかのように振舞う。
  • PoEAAにもある。参照
  • もちろん本当のCollectionに保持したら大変なことになるので、バックエンドではデータベースアクセスが行われたりするわけだが、そういったことを抽象化する。

Fix Mongodb "soft rlimits" Warning On Mac OS X (Yosemite)

If you are seeing Mongo soft rlimits warnings in your logs, or a WARNING: soft rlimits too low.
