Apache CXF: Writing a service with Spring

Apache CXF: Writing a service with Spring

一、设置构建路径（必要的jar包）

commons-logging-1.1.jar
geronimo-activation_1.1_spec-1.0-M1.jar (or Sun's Activation jar)
geronimo-annotation_1.0_spec-1.1.jar (JSR 250)
geronimo-javamail_1.4_spec-1.0-M1.jar (or Sun's JavaMail jar)
geronimo-servlet_2.5_spec-1.1-M1.jar (or Sun's Servlet jar)
geronimo-ws-metadata_2.0_spec-1.1.1.jar (JSR 181)
jaxb-api-2.0.jar
jaxb-impl-2.0.5.jar
jaxws-api-2.0.jar
neethi-2.0.jar
saaj-api-1.3.jar
saaj-impl-1.3.jar
stax-api-1.0.1.jar
wsdl4j-1.6.1.jar
wstx-asl-3.2.1.jar
XmlSchema-1.2.jar
xml-resolver-1.2.jar

aopalliance-1.0.jar
spring-core-2.0.4.jar
spring-beans-2.0.4.jar
spring-context-2.0.4.jar
spring-web-2.0.4.jar

cxf-2.0-incubator.jar

二、编写服务类
a). 接口类HelloService.java

package  demo.spring;

import  java.util.List;

import  javax.jws.WebParam;
import  javax.jws.WebService;

import  demo.spring.model.UserInfoBean;

@WebService
public   interface  HelloService  {

    public String sayHello(@WebParam(name="name")String text);
    
    public UserInfoBean getUserInfo(@WebParam(name="username")String name);
    
    public List<UserInfoBean> getUsers();
}

b).实现类HelloServiceImpl.java

package  demo.spring;

import  java.util.ArrayList;
import  java.util.List;

import  javax.jws.WebService;

import  demo.cxf.server.HelloService;
import  demo.spring.model.UserInfoBean;

@WebService(endpointInterface = " demo.spring.HelloService " )
public   class  HelloServiceImpl  implements  HelloService  {

    public String sayHello(String text) {
        return "Hello,".concat(text);
    }

    public UserInfoBean getUserInfo(String username){
        UserInfoBean user = new UserInfoBean();
        user.setRealname("捷克");
        user.setUsername(username);
        user.setEmail("[email protected]");
        return user;
    }
    
    public List<UserInfoBean> getUsers(){
        List<UserInfoBean> users = new ArrayList<UserInfoBean>();
        users.add(getUserInfo("john"));
        return users;
    }
}

三、声明服务Bean
在WEB-INF目录下创建成一个beans.xml文件，以声明endpoint bean:

<? 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/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd" >

     < 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"   />
     < jaxws:endpoint  id ="helloService"  implementor ="demo.spring.HelloServiceImpl"  address ="/HelloService" />
</ beans >

若使用Spring定义的bean，也可这样声明：

< bean  id ="helloService"  class ="demo.spring.HelloServiceImpl"   />
< jaxws:endpoint  id ="helloServiceImpl"  implementor ="#helloService"  address ="/HelloService"   />

四、定义Servlet
修改WEB-INF/目录下的web.xml文件，添加如下定义：

< 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 >

五、客户端代码
client_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:jaxws ="http://cxf.apache.org/jaxws"
    xsi:schemaLocation ="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schema/jaxws.xsd" >

     < bean  id ="client"  class ="demo.spring.HelloService"  
      factory-bean ="clientFactory"  factory-method ="create" />
    
     < bean  id ="clientFactory"  class ="org.apache.cxf.jaxws.JaxWsProxyFactoryBean" >
       < property  name ="serviceClass"  value ="demo.spring.HelloService" />
       < property  name ="address"  value ="http://localhost:8080/cxf/HelloService" />
     </ bean >
      
</ beans >

client.java

        ClassPathXmlApplicationContext context 
             =   new  ClassPathXmlApplicationContext( new  String[]  {"demo/spring/client/client_beans.xml"} );
        HelloService client  =  (HelloService)context.getBean( " client " );
        String response  =  client.sayHello( " Joe " );
        System.out.println( " Response:  "   +  response);
        
        UserInfoBean user  =  client.getUserInfo( " jack " );
        System.out.println(user.getUsername());
        
        List < UserInfoBean >  users  =  client.getUsers();
         for (UserInfoBean u : users) {
            System.out.println(u.getUsername());
        }
        System.exit( 0 );
