Resourse Oriented Architecture Application Research Based On JAX-RS

The Original of Web invention is to let people easily release information and to link to the internet to get information and resource, But as applications have become more immersersive by using rich client application models and providing personalized content, the Web has grown into a viable platform for software applications. Although Immersive Web applications are very useful, But the immersive architect design of this kind is not compatible with the classical Web rules named Representational State Transfer. The immersive architect design style's disadvantage is the system need to store the session information on the server, it is not easy to improve the system's visibility credibility and flexiblity, besides it is not convenient for the server to realize the load of balance etc.In recent years, the Web application based on the REST architecture style has become more and more sweeping, especially in the enterprise's business interaction and resource intergration, the REST architecture style has acquired extensive attension due to it's special property. The REST architecture style is a bran-new architecture style for Web application, which is a kind of beneficial experiment for the distribute Web system architecture. The REST style's core concept is the Resource, all things as long as it could be referenced, it could be considered to be a Resoure, and the Resource can uniquely be identified by the Uniform Resource Identifier. And the t JAX-RS is a kind of Java API which was defined in SUN's JSR311 criterion for REST application, it could make the java programmer easy to develop REST application by providing some fixed Java API interface. The JAX-RS allow the programmer to use the POJO model and the Annotation along with the JAXB, which could effectively shorten the development period of REST application.The thesis mainly takes the REST and JAX-RS related theory as instruction, mainly focus on the application of Resources-Oriented service according to JAX-RS. The thesis first introduced the issue research background and present research condition briefly, and put forward a overview of domestic and international study state related to this issue research. Then elaborated the REST related theory in briefly and analysized the difference between the REST style and SOAP style summarily and summarized the ROA practise step based on the Resource Oriented Architecture related theory and elalorated JAX-RS resource's CURD realization combined with some practical examples. At last, the thesis focused on the system's Load balance design and resource architecture design based on the forenamed theory, and realized a Resource-oriented and stateless book resource query service through a concrete project go along with simple system function test and interface test etc.
