Apache CXF implements Web Service (3)--tomcat container and normal Servletjax-rs (RESTful) Web service without spring

Start

Refer 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 spring

First 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 the container.

　　The main configuration is in Web. xml

<?xml version= "1.0" encoding= "UTF-8"? ><web-app xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns= "Http://java.sun.com/xml/ns/javaee" xsi:schemalocation= "Http://java.sun.com/xml/ns/javaee/http Java.sun.com/xml/ns/javaee/web-app_2_5.xsd "id=" webapp_id "version=" 2.5 "> <display-name>cxf</ display-name> <servlet> <servlet-name>cxf</servlet-name> <display-name>cxf</ display-name> <servlet-class> Org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet </servlet-class    > <init-param> <param-name>jaxrs.serviceClasses</param-name> <param-value> Com.cnblog.richaaaard.cxftest.servlet.rs.helloworld.service.RoomService </param-value> </init-param>    <init-param> <param-name>jaxrs.providers</param-name> <param-value> Org.codehaus.jackson.jaxrs.JacksonJaxbJsonProvider </param-value> </init-param><load-on-startup >1</load-On-startup></servlet> <servlet-mapping> <servlet-name>cxf</servlet-name> < Url-pattern>/services/*</url-pattern> </servlet-mapping> <session-config> < Session-timeout>60</session-timeout> </session-config></web-app>

You can see that we used Org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet this servlet includes using some of the startup parameters inside:

Jaxrs.serviceclasses

Jaxrs.providers

To configure a restful Web Service whose parameters are consistent with the parameters set in the code Jaxrsserverfactorybean in our previous article.

Start test

We run the Web project in Tomcat in Eclipse

Tomcat runs run as ... Run on Server

At last

We use the browser to access the Tomcat default 8080 port address: http://localhost:8080/cxf/services/roomservice/room

Supplemental servlet configuration parameter Templates

(Note: This is just a template, you need to modify the relevant parameters, do not copy and paste directly into the project)
