jersey2.26+spring5+jpa一步步搭建restful服务

前言

　首先，为什么想选择Jersey做restful服务呢？我个人比较喜欢它的插件化设计，可以方便的注入自己的全局处理逻辑。再一个就是可以生成wadl描述文件，供查询服务方法。所以在学习spring的过程中，特意抽时间做了jersey+spring集成的验证。在本次搭建的过程中，为了在jersey服务中启动spring事务，从网上查阅了不少。先是看到com.sun.jersey例子，后来发现版本比较低，后转过头去看org.glassfish.jersey。吭吭哧哧服务启动了，却又发现无法通过spring容器实例化服务，无法开启事务，拿不到懒加载数据。又查阅资料来回调试，解决版本不匹配的问题，将jersey-spring3升级成jersey-spring4。摸索的过程总是枯燥的，好在总算是一个个问题的排查解决，终究实现了自己想要的功能! 在这里把我自己摸索过程中涉及到的重点位置分享给大家，希望能对大家有所帮助。

一、关于Jersey

　Jersey RESTful 框架是开源的RESTful框架, 实现了JAX-RS (JSR 311 & JSR 339) 规范。它扩展了JAX-RS 参考实现， 提供了更多的特性和工具， 可以进一步地简化 RESTful service 和 client 开发。尽管相对年轻，它已经是一个产品级的 RESTful service 和 client 框架。与Struts类似，它同样可以和hibernate,spring框架整合。

　jersey1.X使用的是sun的com.sun.jersey

　jersey2.X使用的是glassfish的org.glassfish.jersey

二、集成环境说明

　Java：1.8.0_152、SpringMVC：5.0.1.RELEASE、Jersey：2.26-b04、开发工具：eclipse、涉及技术点：springmvc,spring-security,spring data jpa,jersey

三、项目结构简介

　3.1、simm.spring.web是web层，simm.spring.restapi是jersey服务层

　3.2、父级spring-web的POM文件中配置spring jar包依赖
