本篇進行Spring-data-jpa的介紹，幾乎涵蓋該框架的所有方面，在日常的開發當中，基本上能滿足所有需求。這裡不講解JPA和Spring-data-jpa單獨使用，所有的內容都是在和Spring整合的環境中實現。如果需要了解該框架的入門，百度一下，很多入門的介紹。在這篇文章的接下來一篇，會有一個系列來講解mybatis，這個系列從mybatis的入門開始，到基本使用，和spring整合，和第三方外掛整合，快取，外掛，最後會持續到mybatis的架構，原始碼解釋，重點會介紹幾個重要的設計模式，這樣一個體系。基本上講完之後，mybatis在你面前就沒有了祕密，你能解決mybatis的幾乎所有問題，並且在開發過程中相當的方便，駕輕就熟。

這篇文章由於介紹的類容很全，因此很長，如果你需要，那麼可以耐心的看完，本人經歷了很長時間的學識，使用，研究的心血濃縮成為這麼短短的一篇部落格。

大致整理一個提綱：

　　1、Spring-data-jpa的基本介紹；

　　2、和Spring整合；

　　3、基本的使用方式；

　　4、複雜查詢，包括多表關聯，分頁，排序等；

現在開始：

　　1、Spring-data-jpa的基本介紹：JPA誕生的緣由是為了整合第三方ORM框架，建立一種標準的方式，百度百科說是JDK為了實現ORM的天下歸一，目前也是在按照這個方向發展，但是還沒能完全實現。在ORM框架中，Hibernate是一支很大的部隊，使用很廣泛，也很方便，能力也很強，同時Hibernate也是和JPA整合的比較良好，我們可以認為JPA是標準，事實上也是，JPA幾乎都是介面，實現都是Hibernate在做，巨集觀上面看，在JPA的統一之下Hibernate很良好的執行。

　　上面闡述了JPA和Hibernate的關係，那麼Spring-data-jpa又是個什麼東西呢？這地方需要稍微解釋一下，我們做Java開發的都知道Spring的強大，到目前為止，企業級應用Spring幾乎是無所不能，無所不在，已經是事實上的標準了，企業級應用不使用Spring的幾乎沒有，這樣說沒錯吧。而Spring整合第三方框架的能力又很強，他要做的不僅僅是個最早的IOC容器這麼簡單一回事，現在Spring涉及的方面太廣，主要是體現在和第三方工具的整合上。而在與第三方整合這方面，Spring做了持久化這一塊的工作，我個人的感覺是Spring希望把持久化這塊內容也拿下。於是就有了Spring-data-**這一系列包。包括，Spring-data-jpa,Spring-data-template,Spring-data-mongodb,Spring-data-redis，還有個民間產品，mybatis-spring，和前面類似，這是和mybatis整合的第三方包，這些都是乾的持久化工具乾的事兒。

　　這裡介紹Spring-data-jpa，表示與jpa的整合。

　　2、我們都知道，在使用持久化工具的時候，一般都有一個物件來操作資料庫，在原生的Hibernate中叫做Session，在JPA中叫做EntityManager，在MyBatis中叫做SqlSession，通過這個物件來操作資料庫。我們一般按照三層結構來看的話，Service層做業務邏輯處理，Dao層和資料庫打交道，在Dao中，就存在著上面的物件。那麼ORM框架本身提供的功能有什麼呢？答案是基本的CRUD，所有的基礎CRUD框架都提供，我們使用起來感覺很方便，很給力，業務邏輯層面的處理ORM是沒有提供的，如果使用原生的框架，業務邏輯程式碼我們一般會自定義，會自己去寫SQL語句，然後執行。在這個時候，Spring-data-jpa的威力就體現出來了，ORM提供的能力他都提供，ORM框架沒有提供的業務邏輯功能Spring-data-jpa也提供，全方位的解決使用者的需求。使用Spring-data-jpa進行開發的過程中，常用的功能，我們幾乎不需要寫一條sql語句，至少在我看來，企業級應用基本上可以不用寫任何一條sql，當然spring-data-jpa也提供自己寫sql的方式，這個就看個人怎麼選擇，都可以。我覺得都行。

　　2.1與Spring整合我們從spring配置檔案開始，為了節省篇幅，這裡我只寫出配置檔案的結構。

　　2.2對上面的配置檔案進行簡單的解釋，只對“實體管理器”和“dao”進行解釋，其他的配置在任何地方都差不太多。

　　　　1.對“實體管理器”解釋：我們知道原生的jpa的配置資訊是必須放在META-INF目錄下面的，並且名字必須叫做persistence.xml，這個叫做persistence-unit，就叫做持久化單元，放在這下面我們感覺不方便，不好，於是Spring提供了

org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean

這樣一個類，可以讓你的隨心所欲的起這個配置檔案的名字，也可以隨心所欲的修改這個檔案的位置，只需要在這裡指向這個位置就行。然而更加方便的做法是，直接把配置資訊就寫在這裡更好，於是就有了這實體管理器這個bean。使用

<property name="packagesToScan" value="your entity package" />

這個屬性來載入我們的entity。

　　2.3 解釋“dao”這個bean。這裡衍生一下，進行一下名詞解釋，我們知道dao這個層叫做Data Access Object，資料庫訪問物件，這是一個廣泛的詞語，在jpa當中，我們還有一個詞語叫做Repository，這裡我們一般就用Repository結尾來表示這個dao，比如UserDao，這裡我們使用UserRepository，當然名字無所謂，隨意取，你可以意會一下我的意思，感受一下這裡的含義和區別，同理，在mybatis中我們一般也不叫dao，mybatis由於使用xml對映檔案（當然也提供註解，但是官方文件上面表示在有些地方，比如多表的複雜查詢方面，註解還是無解，只能xml），我們一般使用mapper結尾，比如我們也不叫UserDao，而叫UserMapper。

　　上面拓展了一下關於dao的解釋，那麼這裡的這個配置資訊是什麼意思呢？首先base-package屬性，代表你的Repository介面的位置，repository-impl-postfix屬性代表介面的實現類的字尾結尾字元，比如我們的UserRepository，那麼他的實現類就叫做UserRepositoryImpl，和我們平時的使用習慣完全一致，於此同時，spring-data-jpa的習慣是介面和實現類都需要放在同一個包裡面（不知道有沒有其他方式能分開放，這不是重點，放在一起也無所謂，影響不大），再次的，這裡我們的UserRepositoryImpl這個類的定義的時候我們不需要去指定實現UserRepository介面，根據spring-data-jpa自動就能判斷二者的關係。

　　比如：我們的UserRepository和UserRepositoryImpl這兩個類就像下面這樣來
