Very early, very early, on the preliminary study of WebService, the feeling is still relatively "good".
With Web services, it feels like a normal API, compared to an HTTP interface.
WebService has a big limitation, that is, the problem of distributed transactions has risen a lot, not yet.
The last 1 years to do 2 more complete projects, have WebService configuration, but, are configured by others.
Others, after all, is someone else's.
As a programmer who loves to learn and apply my knowledge, I will also make a configuration for myself.
The following example, I personally step by step today, and run successfully.
csdn:http://download.csdn.net/detail/fansunion/9218657
(I intend to further refine the example on this basis.)
First, WebServiceClient interface project
Other projects if you want to use a Web service, call the interface directly, there is no need to focus on the implementation of the service.
@WebServicepublic interface Userfacade {String query ();}
Interface, has been the most minimalist. Querying a string indicates that the Web service invocation succeeded.
Package Cn.fansunion.webservice.test;import Org.springframework.context.applicationcontext;import Org.springframework.context.support.classpathxmlapplicationcontext;import Cn.fansunion.webservice.UserFacade; public class WebServiceTest {public static void main (string[] args) {//Initializes the spring context, The WebService file is located in the SRC directory (or classpath) applicationcontext ac = new Classpathxmlapplicationcontext ("classpath:/ Spring-webservice.xml ");//Get bean by ID, I feel this" jaxws:client id= "Remoteuserfacade" " The combination of WebService syntax and spring syntax Userfacade userfacade= (userfacade) Ac.getbean ("Remoteuserfacade");//query, return and print the string " WebService "System.out.println (Userfacade.query ());}}
Spring-webservice.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:context= "Http://www.springframework.org/schema/context" xmlns:aop= "HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP" xmlns:jaxws= "Http://cxf.apache.org/jaxws" xmlns:soap= "http ://cxf.apache.org/bindings/soap "xmlns:util=" Http://www.springframework.org/schema/util "xsi:schemalocation=" Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd/HTTP Www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd/HTTP Cxf.apache.org/bindings/soap http://cxf.apache.org/schemas/configuration/soap.xsd Http://cxf.apache.org/jaxws Http://cxf.apache.org/schemas/jaxws.xsd HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP http://www.springframework.org /schema/aop/spring-aop.xsd Http://www.springframework.org/schema/util Http://www.springframewOrk.org/schema/util/spring-util-3.0.xsd "><!--enable Autowire--><context:annotation-config/>< Context:component-scan base-package= "Com.fansunion.webservice"/><jaxws:client id= "Remoteuserfacade" address = "Http://localhost:8080/webService/UserFacade" serviceclass= "Cn.fansunion.webservice.UserFacade"/></beans >
The key is Jaxws:client id= "Remoteuserfacade", this is the core configuration of WebService.
In addition, you need to pay attention to the Http://cxf.apache.org/jaxws xsi and xmlns configuration, if not, should be an error.
Pom.xml Configuration
<dependency><groupid>org.springframework</groupid><artifactid>spring-webmvc</ Artifactid><version>${spring.version}</version></dependency><dependency><groupid >org.aspectj</groupid><artifactid>aspectjweaver</artifactid><version>${ Aspectj.version}</version></dependency><dependency><groupid>org.aspectj</groupid ><artifactid>aspectjrt</artifactid><version>${aspectj.version}</version></ Dependency><dependency><groupid>org.apache.cxf</groupid><artifactid> cxf-rt-frontend-jaxws</artifactid><version>${cxf.version}</version></dependency>< dependency><groupid>org.apache.cxf</groupid><artifactid>cxf-rt-transports-http</ Artifactid><version>${cxf.version}</version></dependency></dependencies>
Second, the implementation of the Webserviceimpl interface project
Package Cn.fansunion.webservice.impl;import Javax.jws.webservice;import Org.springframework.stereotype.Service; Import Cn.fansunion.webservice.UserFacade; @WebService (endpointinterface = "Cn.fansunion.webservice.UserFacade", ServiceName = "Userfacade") @Service ("Userfacadeimpl") public class Userfacdeimpl implements Userfacade {@ Overridepublic String Query () {return ' WebService ';}}
The WebService annotation is more than the normal Java interface implementation class.
It seems that endpointinterface and servicename are critical.
It is not clear whether these 2 properties are necessary, according to my own experience, is optional, if not written, will follow a certain rule with the default name and class.
Just finished writing, I feel wrong.
Endpointinterface is supposed to be required, of course, if not written, the program can be completely analyzed, because there is "implements".
Interested in, own Baidu.
The Userfacdeimpl needs to be published as a web, followed by the CONFIG. xml file.
Spring configuration file, basically understand, mainly is configured WebService Cxfservlet.
<?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 "version=" 2.5 "> <context-param> <param-name> contextconfiglocation</param-name> <param-value> Classpath:spring-webservice.xml </param -value> </context-param> <listener> <listener-class> Org.springframework.web.context.contextloaderlistener</listener-class> </listener> <servlet> <servlet-name>cxf</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.cxfservlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> & Lt;servlet-name>cxf</servlet-name> <url-pattern>/webService/*</url-pattern> </ Servlet-mapping> </web-app>
Spring-webservice.xml
<!--Import CXF--><import resource= "Classpath:meta-inf/cxf/cxf.xml"/><import resource= "classpath: Meta-inf/cxf/cxf-extension-soap.xml "/><import resource=" Classpath:meta-inf/cxf/cxf-servlet.xml "/>< Bean id= "Userfacade" class= "Cn.fansunion.webservice.impl.UserFacdeImpl" ></bean><jaxws:server id= " Webserviceuserfacade "servicebean=" #userFacade "address="/userfacade "></jaxws:server><!--enable Autowire- -><context:annotation-config/><context:component-scan base-package= "Com.fansunion.webservice"/>
Introduce the XML configuration of CXF, configure the Bean, the most important or "jaxws:server", and the client project "Jaxws:client" corresponds to it ~
Pom.xml
Exactly the same as before
Iii. A brief review of the
Userfacadeclient Project: Just one interface Userfacade
Userfacadeimpl Project: interface Implementation Userfacadeimpl, Spring-webservice.xml, Pom.xml, Web. xml
Test items: WebServiceTest, Pom.xml, Spring-webservice.xml
For convenience, we put the test project together directly with the Client interface project ~
Iv. Testing and operating processes

WebService
3. You can also access http://localhost:8080/webService/UserFacade/query?wsdl
View the definition of this webservice
I want to access http://localhost:8080/webService/UserFacade/query?wsdl similar URLs through a browser, directly displaying the returned results.
It seems not very good, oh, back to study it ~
V. Final description
1. For the sake of simplicity, these 2 projects are very simple, with no trivial code and configuration at all with WebService.
It's a perfectly formed, huh?
2. For the sake of simplicity, the server uses localhost, and it's written dead, you know ~
3. See the service and application start-up log, is very valuable ~
This is the first to summarize here ~
