Spring unit testing, embedded RESTEasy service implementation

RESTEasy Introduction

RESTEasy is an open-source project of JBoss. It provides various frameworks to help you build RESTful Web Services and RESTful Java applications. It is a complete implementation of JAX-RS specifications and passes JCP certification. As a JBOSS project, it can be well integrated with the JBOSS application server. However, it can also run in any Servlet container that runs JDK 5 or a later version. RESTEasy also provides a RESTEasy JAX-RS client call framework. It can be easily integrated with EJB, Seam, Guice, Spring and Spring MVC. Supports automatic GZIP decompression on the client and server.
Based on the previous article, implement SpringJUnit4ClassRunner
