Spring Boot 本身自带已经集成JPA,实现JPA规范最好的是hibernation， 最近几年中持久层框架中应用更多是MyBatis,原因呢？Hibernate 的灵活性没有Mybatis好，而且Hibernate的学习成本相对于MyBatis要高很多。
应用按照分层的理念进行了拆分，它具有高度的可扩展性.将公共抽离出来,做成服务供其他模块调用。实现RPC
可以采用RMI、Hession,但是
但是由于服务越来越多，依赖难以管理，而且RPC调用没有负载均衡，服务心跳检查。。。救星到来。。。阿里Dubbo（RPC服务治理框架）
客户端层：客户端层包含了针对目标平台的用户界面，可能会包括基于Web的、移动端用户界面。一般来讲，这可能会是Web应用，包含诸如用户管理、会话管理、页面构建等功能，客户端所发起Http请求,都需要以RESTful服务的形式返回。
服务端：服务端包含了数据的选取，数据的来源诸如关系型数据库、Redis、memcache，对外提供服务。
应用技术：
