Restful cxf spring integration 1 (release of the WSDL Interface)

I have been writing this article for a long time. I will write it if I have nothing to do today!

There were not many contacts with cxf before, so I didn't understand it very well. During this time, the project needs to be studied.

The first step is to understand the restful interface. You can also publish the WSDL interface. Previously, the rest interface only published a service, and its interface service method is described in the usage documentation, however, the rest interface released later is a wsdl interface.

The project requires support from spring core, Spring AOP, cxf, and other related packages.

The demo project target is used as a user add (post) and query (get) function.

There are three files in total:

1. Users. Java
2. Beans. xml
3. Web. xml

Java users class:

package com.ly.cxf.demo;import java.util.ArrayList;import java.util.List;import javax.ws.rs.GET;import javax.ws.rs.POST;import javax.ws.rs.Path;import javax.ws.rs.PathParam;import javax.ws.rs.Produces;import javax.ws.rs.core.MediaType;// @WebService(targetNamespace="http://com.ly.cxf.demo")@Path("/getInfo")public class Users {static List<String> users = null;{if (users == null) {users=new ArrayList<String>();users.add("yinlei");}}@GET@Produces( { MediaType.APPLICATION_XML })// http://localhost:8080/sprcxf/api/getInfopublic String getUserInfo() {String ret = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><users>";for (String u : users) {ret = ret + "<user><name>" + u + "</name></user>";}ret =ret+"</users>";return ret;}@POST@Produces( { MediaType.APPLICATION_XML })@Path("/{user}")//http://localhost:8080/sprcxf/api/getInfo/testAnyUserNamepublic String postUserInfo(@PathParam("user") String user) {users.add(user);return "<?xml version=\"1.0\" encoding=\"UTF-8\"?><retMsg>OK</retMsg>";}}

Beans. xml file:

<?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:jaxws="http://cxf.apache.org/jaxws"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://cxf.apache.org/jaxwshttp://cxf.apache.org/schemas/jaxws.xsdhttp://cxf.apache.org/jaxrs    http://cxf.apache.org/schemas/jaxrs.xsd"xmlns:jaxrs="http://cxf.apache.org/jaxrs">  <import resource="classpath:META-INF/cxf/cxf.xml"/>  <!--jetty <import resource="classpath:META-INF/cxf/cxf-extension-http-binding.xml"/> -->  <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>    <bean id="restSample" class="com.ly.cxf.demo.Users"/>   <jaxrs:server id="restServiceContainer" address="/api">    <jaxrs:serviceBeans>        <ref bean="restSample" />    </jaxrs:serviceBeans></jaxrs:server>  </beans>

Web. xml file:

------------------------ Source code end split line ----------------------------

Enter http: // localhost: 8080/sprcxf/

Click the link shown in the figure to go To the WSDL interface description page:

Usage:

Get http: /localhost: 8080/sprcxf/API/getinfo

Post http: // localhost: 8080/sprcxf/API/getinfo/anyusername

Conclusion: the benefit of using this rest interface is that it automatically provides the WSDL interface description file. It is easy to understand.
