在上一篇“使用Spring MVC 4构建Restful服务”博文中，我们谈到了如何使用Spring MVC 4搭建RESTful服务，本文以上篇文章为基础，继续讲解如何解析Spring RESTful服务。上篇文章中，我们用了jacson包进行Java对象的序列化，本文仍然使用此包进行Java对象的反序列化。

构建RESTful服务

1.我们继续在 FavRestfulController 类中，新增 buildRestUser() 方法，将FavUser对象序列化成JSON对象输出，代码如下：

<table style="padding:0px; margin:0px auto 10px; font-size:12px; border-collapse:collapse"> 
 <tbody style="padding:0px!important; margin:0px!important; border:0px!important; bottom:auto!important; float:none!important; left:auto!important; line-height:1.1em!important; outline:0px!important; overflow:visible!important; position:static!important; right:auto!important; top:auto!important; vertical-align:baseline!important; width:auto!important; font-size:1em!important; min-height:inherit!important; background:none!important"> 
  <tr style="padding:0px!important; margin:0px!important; font-size:1em!important; border:0px!important; bottom:auto!important; float:none!important; left:auto!important; line-height:1.1em!important; outline:0px!important; overflow:visible!important; position:static!important; right:auto!important; top:auto!important; vertical-align:baseline!important; width:auto!important; min-height:inherit!important; background:none!important">

2.启动favspringmvcrestful工程，使用Firefox的RESTClient插件进行测试，在URL中输入[http://localhost][http_localhost]:8080/favspringmvcrestful/buildRestUser，输出如下图所示的结果，RESTful服务搭建完成。

解析RESTful服务

1. 新建“ConsumeRESTful” Java Project，在Build Path中导入工程所需的Jar。

[![wKioL1RrQDjwbP5dAAQOgt7G\_\_s789.jpg][wKioL1RrQDjwbP5dAAQOgt7G_s789.jpg]][wKioL1RrQDjwbP5dAAQOgt7G_s789.jpg]

2. 导入FavUser.Java对象，注意：该对象中的日期类型应该与构建RESTful服务中的FavUser对象的日期类型一致，即对createDate的Getter方法进行格式化，否则在反序列化过程中会报错。

3. 新建 ConsumeSpringRestful.java ，在Main()方法中，测试RESTful服务。
