一、软件准备

Eclipse 4.2.1

Maven 2.2.1

Spring 3.2.6

CXF 3.0.2

软件下载和Eclipse 安装 maven插件等请参考其他文章。

二、步骤

1. 新建web工程，利用maven管理，如下：

工程名为test，完成以后，项目结构如下图：

src/main/java 准备放 java 程序；

src/main/resources准备放各类资源文件。

2. 添加代码

1) 定义服务接口

package com.test;
import javax.jws.WebService;
@WebService
public interface HelloWorld {
public String sayHello();
}

因为只是一个webservice的实验程序，所以非常简单，只有一个服务方法： sayHello()，利用 @WebService注解来声明这是一个webservice的接口。

2) 实现服务类

package com.test;
import javax.jws.WebService;
@WebService
public class HelloWorldImpl implements HelloWorld{
public String sayHello(){
return "Hello world!";
}
}

完成java代码添加后的项目结构如下：

3. 添加Spring-CXF 配置

在项目 src/main/webapp/WEB-INF 目录下新建XML定义：cxf-servlet.xml如下：

<?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-servlet.xml"/>
<jaxws:endpoint id="helloWorld" implementor="com.test.HelloWorldImpl" address="/HelloWorld"/>
</beans>

该定义文件利用spring和CXF的功能，发布一个ID为helloWorld，实现类为com.test.HelloWorldImpl，发布相对路径为 /HelloWorld（对应绝对目录为： http://host:port/{WebAPPName}/HelloWorld）的 webservice。

因为我们需要用到CXF来做webservice，右键点击项目中的POM.XML，添加apache-cxf依赖，如下图：

4. Web应用配置

修改 src/main/webapp/WEB-INF 目录下的web.xml文件

<?xml version="1.0" encoding="UTF-8"?>

-->
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<display-name>cxf</display-name>
<servlet>
<description>Apache CXF Endpoint</description>
<display-name>cxf</display-name>
<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>
<servlet-name>cxf</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>60</session-timeout>
</session-config>
</web-app>

该文件实际上是定义了处理webservice的CXF Servlet的映射关系。

完成步骤3和4以后的工程目录如下：

5. 编译打包

利用maven（package -X）编译打包成test.war

(在Eclipse上右击工程名 Run as -> Maven build）

6. 将步骤5生成的test.war部署到tomcat服务器上

7. 访问测试：

在浏览器上输入：http://localhost:8080/test/，出现如下画面就成功了：

点击WSDL链接：

8. 编写webservice client端代码

1) 首先通过 Spring 与 CXF 的配置来定义 Web Service 的客户端 Bean，在 src\main\resources 目录下创建client-beans.xml 配置文件:

<?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/schema/jaxws.xsd">
<bean id="client" class="com.test.HelloWorld"
factory-bean="clientFactory" factory-method="create"/>
<bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
<property name="serviceClass" value="com.test.HelloWorld"/>
<property name="address" value="http://localhost:8080/test/HelloWorld"/>
</bean>
</beans>

需要注意的是，该配置文件中的 address需要写成发布服务的绝对路径。

2) 编写客户端java代码: HelloWorldClient.java

package com.test;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public final class HelloWorldClient {
private HelloWorldClient() {
}
public static void main(String args[]) throws Exception {
// START SNIPPET: client
ClassPathXmlApplicationContext context
= new ClassPathXmlApplicationContext(new String[] {"client-beans.xml"});
HelloWorld client = (HelloWorld)context.getBean("client");
String response = client.sayHello();
System.out.println("Response: " + response);
System.exit(0);
// END SNIPPET: client
}
}

注意，代码中HelloWorldclient = (HelloWorld)context.getBean("client"); 的client需要与"client-beans.xml"中的 bean id一致才能找到这个服务。

现在的项目结构如下：

3) 连接测试

在eclipse中直接按HelloWorldClient运行 Run as -> Java Application:

输出的Hello world! 即是我们发布的HelloWorld的方法 sayHello()的输出！这说明从服务发布到客户端连接都成功了。
