Spring Data是什么
Spring Data是一个用于简化数据库访问，并支持云服务的开源框架。其主要目标是使得对数据的访问变得方便快捷，并支持map-reduce框架和云计算数据服务。 Spring Data 包含多个子项目： Commons - 提供共享的基础框架，适合各个子项目使用，支持跨数据库持久化 JPA - 简化创建 JPA 数据访问层和跨存储的持久层功能 Hadoop - 基于 Spring 的 Hadoop 作业配置和一个 POJO 编程模型的 MapReduce 作业 Key-Value - 集成了 Redis 和 Riak ，提供多个常用场景下的简单封装 Document - 集成文档数据库：CouchDB 和 MongoDB 并提供基本的配置映射和资料库支持 Graph - 集成 Neo4j 提供强大的基于 POJO 的编程模型 Graph Roo AddOn - Roo support for Neo4j JDBC Extensions - 支持 Oracle RAD、高级队列和高级数据类型 Mapping - 基于 Grails 的提供对象映射框架，支持不同的数据库 Examples - 示例程序、文档和图数据库 Guidance - 高级文档 Spring Data JPA是什么 由Spring提供的一个用于简化JPA开发的框架Spring Data JPA能干什么
可以极大的简化JPA的写法，可以在几乎不用写实现的情况下，实现对数据的访问和操作。除了CRUD外，还包括如分页、排序等一些常用的功能。Spring Data JPA有什么主要来看看Spring Data JPA提供的接口，也是Spring Data JPA的核心概念：1：Repository：最顶层的接口，是一个空的接口，目的是为了统一所有Repository的类型，且能让组件扫描的时候自动识别。2：CrudRepository ：是Repository的子接口，提供CRUD的功能3：PagingAndSortingRepository：是CrudRepository的子接口，添加分页和排序的功能4：JpaRepository：是PagingAndSortingRepository的子接口，增加了一些实用的功能，比如：批量操作等。5：JpaSpecificationExecutor：用来做负责查询的接口6：Specification：是Spring Data JPA提供的一个查询规范，要做复杂的查询，只需围绕这个规范来设置查询条件即可环境搭建：
在Eclipse里面构建一个普通的Java工程，主要就是要加入一堆的jar包。1：首先去官网下载Spring Data Common 和 Spring Data JPA的包，把里面dist的jar包加入到工程中，这里是spring-data-commons-1.5.0.RELEASE.jar和spring-data-jpa-1.3.2.RELEASE.jar2：把Spring3.2.3的jar包添加到工程中3：JPA的实现选用的是Hibernate4.2.0，总共还需要额外加入如下的jar：antlr-2.7.7.jar、aopalliance-1.0.jar、asm-3.2.jar、aspectjrt-1.7.1.jar、aspectjweaver-1.7.1.jar、commons-beanutils-1.8.3.jar、commons-codec-1.7.jar、commons-collections-3.2.1.jar、commons-dbcp-1.4.jar、commons-fileupload-1.2.2.jar、commons-io-2.4.jar、commons-lang3-3.1.jar、commons-logging-1.1.1.jar、commons-pool-1.6.jar、dom4j-1.6.1.jar、hibernate-commons-annotations-4.0.1.Final.jar、hibernate-core-4.2.0.Final.jar、hibernate-entitymanager-4.2.0.Final.jar、hibernate-jpa-2.0-api-1.0.1.Final.jar、javassist-3.15.0-GA.jar、jboss-logging-3.1.0.GA.jar、jboss-transaction-api_1.1_spec-1.0.0.Final.jar、mysql-connector-java-5.1.9.jar、slf4j-api-1.7.3.jar（以上jar包作为参考，下面是用maven项目搭建的环境）通过maven+springmvc+spring测试：
