摘要: 自Spring One大会后，Spring的功能增强了许多，本文就Spring整合JPA问题进行改进。
在标准JPA中，持久化单元默认被定义在META-INF/persistence.xml文件中，并且通过@Entity注解搜索获得。但是大多数情况下，持久化单元不会仅仅存在一个，并且数据源也不会是一个，基于这个原因，Spring提供了一个可选方案，即通过LocalEntityManagerFactoryBean和LocalContainerEntityManagerFactoryBean进行管理。localEntityManagerFactoryBean扩展功能太少，这个不说，我们以LocalContainerEntityManagerFactoryBean为例。
我们的一般做法是：
创建persistence.xml文件
配置Spring上下文
&persistence xmlns="/xml/ns/persistence" version="1.0"&
&persistence-unit name="hibernatePersistenceUnit" transaction-type="RESOURCE_LOCAL"&
&properties&
&property name="hibernate.hbm2ddl.auto" value="update" /&
&property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/&
&/properties&
&/persistence-unit&
&/persistence&
然后再在Spring中引入persistence.xml配置文件，
&bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
p:persistenceXmlLocation="classpath*:META-INF/persistence.xml"
p:persistenceUnitName="hibernatePersistenceUnit"
p:dataSource-ref="jpaDataSource"
p:jpaVendorAdapter-ref="hibernateVendor"/&
&bean id="hibernateVendor" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"
p:showSql="false"/&
基于文档需求，我们希望移除persistence.xml文件，但是如何声明外部配置文件从而关联到ORM框架中呢？并且如何让EntityManagerFactory工厂类知道我们当初配置的实体在哪里。
可以这样：
删除META-INF/persistence.xml配置文件
声明packagesToScan属性
声明jpaPropertyMap属性
最终配置如下：
&bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
p:packagesToScan="org.krams.tutorial.domain"
p:dataSource-ref="jpaDataSource"
p:jpaVendorAdapter-ref="hibernateVendor"
p:jpaPropertyMap-ref="jpaPropertyMap"/&
&util:map id="jpaPropertyMap"&
&entry key="hibernate.hbm2ddl.auto" value="update"/&
&entry key="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/&
&/util:map&
&bean id="hibernateVendor" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"
p:showSql="false"/&
这样做的好处是，当真正需要调用相应的实体对象时再进行数据源的配置，让Spring自动管理工厂，这样即使数据源再多也不怕出现冲突。

有朋友说jpa相比mybatis太难用，多表联合的查询写起来也比较费劲，所以便加入了mybatis的支持，在配置jpa时遇到各种问题，需要修改相关配置文件，下面小编给大家分享下修改配置文件的思路，感兴趣的朋友参考下
前一阵子接手了一个使用SpringBoot 和spring-data-jpa开发的项目，后期新加入一个小伙伴，表示jpa相比mybatis太难用，多表联合的查询写起来也比较费劲，所以便加入了mybatis的支持
开始的时候
@Configuration
@EnableJpaRepositories("com.xxx.xxx.repository")
class JpaConfig
使用这种方式去配置的jpa，遇到一个问题，就是能select 但是不能save，所以就修改为配置文件的方式：
下面直接上配置文件：
1、spring的配置
&?xml version="1.0" encoding="UTF-8"?&
&beans xmlns="http://www.springframework.org/schema/beans"
