Apache CXF: Writing a service with Spring

一、設置構建路徑（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、編寫服務類
a). 接口類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).實現類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("jack@chaina.com");

return user;

}

public List<UserInfoBean> getUsers(){

List<UserInfoBean> users = new ArrayList<UserInfoBean>();

users.add(getUserInfo("john"));

return users;

}

三、聲明服務Bean
在WEB-INF目錄下創建成一個beans.xml文件，以聲明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">

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

</beans>

若使用Spring定義的bean，也可這樣聲明：

<jaxws:endpoint id="helloServiceImpl" implementor="#helloService" address="/HelloService" />

四、定義Servlet
修改WEB-INF/目錄下的web.xml文件，添加如下定義：

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>WEB-INF/beans.xml</param-value>

</context-param>

<listener-class>

org.springframework.web.context.ContextLoaderListener

</listener-class>

</listener>

<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、客戶端代碼
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>

</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);
