整合
- spring整合spring data jpa
- 其实就是spring data jpa 把控制权获取到,由spring data jpa来管理,不让spring管理
配置JPA延迟session关闭
- xml配置
<filter>
<filter-name>openEntityManagerInViewFilter</filter-name>
<filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>openEntityManagerInViewFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
配置JPA工厂Bean
- 在spring的applicationContext.xml引入spring data jpa名称空间
<?xml version="1.0" encoding="UTF-8"?>

- 配置entityManagerFactory ,JPA编程核心接口 EntityManager (类似Session, 进行增删改查 )基于jpa进行事务管理
<!-- spring整合JPA -->
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="cn.lwb.bos.domain" />
<property name="persistenceProvider">
<bean class="org.hibernate.ejb.HibernatePersistence" />
</property>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<!-- 自动建表 -->
<property name="generateDdl" value="true" />
<property name="database" value="ORACLE" />
<property name="databasePlatform" value="org.hibernate.dialect.Oracle10gDialect" />
<property name="showSql" value="true" />
</bean>
</property>
<property name="jpaDialect">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
</property>
</bean>
事物管理
<!-- 事务管理器 -->
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<!-- 需要注入 entityManagerFactory-->
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
扫描实现类
- 扫描DAO接口,自动生成实现类
<!-- 扫描DAO接口,自动生成实现类 -->
<jpa:repositories base-package="cn.lwb.bos.dao" />
