总结篇-Spring-SpringMVC-Hibernate-jpa整合

之前介绍了许多hibernate和JPA的关系，但是说的再多，不如亲手实践一下，本文主要是Spring-SpringMVC-Hibernate-jpa整合，充分用到实践中来。

开发步骤：

1.导入SSH框架整合的jar包

1.1导入SpringMVCj的ar包

1.2导入Hibernate的jar包

1.3导入三方依赖的包

1.4导入mysql驱动包

2.配置web.xml

2.1配置Spring IOC容器

2.2配置SpringMVC的控制器（servlet）

2.3配置编码等过滤器

3.配置SpringMVC

3.1配置自动扫描的包

3.2配置视图解析器

3.3配置静态资源

3.4配置注解

4.配置Spring

4.1配置自动扫描的包

4.2配置数据源

4.3配置DataSource

4.4整合Hibernate

4.4.1配置entityManagerFactory 实体管理器

4.4.2配置事务管理器

4.4.3配置支持注解的事务

4.4.4配置spring-data

工程截图如下：

具体配置如下：
