Configuring JAX-RS services in container with Spring configuration file.

web.xml

In web.xml one needs to register one or more CXFServlet(s) and link to an application context configuration.

Using Spring ContextLoaderListener

<?xml version="1.0" encoding="ISO-8859-1"?>   <!DOCTYPE web-app     PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"     "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app>     <context-param>         <param-name>contextConfigLocation</param-name>         <param-value>WEB-INF/beans.xml</param-value>     </context-param>       <listener>         <listener-class>             org.springframework.web.context.ContextLoaderListener         </listener-class>     </listener>       <servlet>         <servlet-name>CXFServlet</servlet-name>         <display-name>CXF Servlet</display-name>         <servlet-class>             org.apache.cxf.transport.servlet.CXFServlet         </servlet-class>         <load-on-startup>1</load-on-startup>     </servlet>       <servlet-mapping>         <servlet-name>CXFServlet</servlet-name>         <url-pattern>/*</url-pattern>     </servlet-mapping> </web-app>

The application context configuration is shared between all the CXFServlets

Using CXFServlet init parameters

<?xml version="1.0" encoding="ISO-8859-1"?>   <!DOCTYPE web-app     PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"     "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app>     <servlet>         <servlet-name>CXFServlet1</servlet-name>         <display-name>CXF Servlet1</display-name>         <servlet-class>             org.apache.cxf.transport.servlet.CXFServlet         </servlet-class>                 <init-param>                    <param-name>config-location</param-name>                    <param-value>/WEB-INF/beans1.xml</param-value>                 </init-param>         <load-on-startup>1</load-on-startup>     </servlet>           <servlet>         <servlet-name>CXFServlet2</servlet-name>         <display-name>CXF Servlet2</display-name>         <servlet-class>             org.apache.cxf.transport.servlet.CXFServlet         </servlet-class>                 <init-param>                    <param-name>config-location</param-name>                    <param-value>/WEB-INF/beans2.xml</param-value>                 </init-param>         <load-on-startup>1</load-on-startup>     </servlet>         <servlet-mapping>         <servlet-name>CXFServlet1</servlet-name>         <url-pattern>/1/*</url-pattern>     </servlet-mapping>           <servlet-mapping>         <servlet-name>CXFServlet2</servlet-name>         <url-pattern>/2/*</url-pattern>     </servlet-mapping> </web-app>

Each CXFServlet can get a unique application context configuration. Note, no Spring ContextLoaderListener is registered in web.xml in this case.

beans.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xmlns:jaxrs="http://cxf.apache.org/jaxrs"   xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd">     <!-- do not use import statements if CXFServlet init parameters link to this beans.xml -->     <import resource="classpath:META-INF/cxf/cxf.xml" />   <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />     <jaxrs:server id="customerService" address="/service1">     <jaxrs:serviceBeans>       <ref bean="customerBean" />     </jaxrs:serviceBeans>   </jaxrs:server>     <bean id="customerBean" class="demo.jaxrs.server.CustomerService" /> </beans>

In the above configuration all resources will be configured as singletons, see below for information on creating per-request resources.
