But because the bottom of it is using the Java technology, so it is still more cumbersome to

1. What is Jax-rs?Jax-rs is a new technology introduced by Java EE6. Jax-rs, the Java API for RESTful Web Services, is an application interface for the Java programming language that supports the creation of WEB services in the Representational state Transfer (REST) architectural style.Jax-rs uses Java annotations intr

Introduction Over the past few years, rest has become an important concept that affects the design of web frameworks, Web protocols, and Web applications. It is not surprising that more and more companies now want to expose web APIs in ways that are simple and fit the Web architecture itself, so rest becomes more and more important. The rich browsers that use Ajax to communicate are also moving towards this goal. This architectural principle increases the scalability of the World Wide Web, and

StartRefer to another article in this series:Apache CXF implements Web Service (2)-A pure Jax-rs (RESTful) Web service without the use of heavyweight web containers and springFirst create a new dynamic web Project in Eclipse and then implement all the classes in the previous article, except here we don't need a server.java to start a Web Service. We use CXF's own org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet to launch a Web service service in

In the previous section, we have successfully defined a rest service and provided specific implementation, but we still need to run it. In the previous sectionEquipmentIt lists the required jar (run in Tomcat) and optional jar (run as an independent application ). This section describes how to run the program as an Independent Application and how to run the program in Tomcat. Tomcat (or other Web containers) To run in a tomcat container, you must first define an application class:Java code Im
