Apache CXF实战之一 Hello World Web Service

书接上文，下面看看CXF怎样和spring集成。

1.创建HelloWorld 接口类

package com.googlecode.garbagecan.cxfstudy.helloworld;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

@WebService
public interface HelloWorld {
    @WebMethod
    @WebResult String sayHi(@WebParam String text);
}

2.创建HelloWorld实现类 

package com.googlecode.garbagecan.cxfstudy.helloworld;

public class HelloWorldImpl implements HelloWorld {

    public String sayHi(String name) {
        String msg = "Hello " + name + "!";
        return msg;
    }
}

3.修改web.xml文件

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>

    <display-name>cxfstudy</display-name>

    <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>
        <servlet-name>cxf</servlet-name>
        <url-pattern>/ws/*</url-pattern>
    </servlet-mapping>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:**/spring.xml</param-value>
    </context-param>
    
</web-app>

4.创建spring配置文件并放在classpath路径下

<?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-extension-soap.xml" />
    <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
    <jaxws:endpoint id="helloworld" implementor="com.googlecode.garbagecan.cxfstudy.helloworld.HelloWorldImpl" address="/HelloWorld" />
    
    <!-- For client test -->
    <jaxws:client id="helloworldClient" address="http://localhost:9000/ws/HelloWorld" serviceClass="com.googlecode.garbagecan.cxfstudy.helloworld.HelloWorld" />   
</beans>

5.创建测试类

package com.googlecode.garbagecan.cxfstudy.helloworld;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class SpringClient {
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
        HelloWorld helloworld = (HelloWorld)context.getBean("helloworldClient");
        System.out.println(helloworld.sayHi("kongxx"));
    }
}

6.测试

6.1 首先启动tomcat或者使用maven的jetty，并访问http://localhost:9000/ws/HelloWorld?wsdl来验证web service已经启动并且生效；

6.2 然后运行测试类来验证web service。
