cxf-spring

webservice如今开发运用已经很容易了,这都得益于巨头们的努力.众多框架:cxf……
这个示例也是用的cxf，这是我的第一个webservice 例子,jar包这里没有上传，可以到官网下载。
HelloService.java代码：

package org.iteye.bbjava.ws.service;

import javax.jws.WebService;

@WebService
public interface HelloService {
	String sayHi(String text);
}

HelloServcieImpl.java代码:

package org.iteye.bbjava.ws.service.impl;

import javax.jws.WebService;

import org.iteye.bbjava.ws.service.HelloService;

@WebService(endpointInterface = "org.iteye.bbjava.ws.service.HelloService")
public class HelloServiceImpl implements HelloService {

	public String sayHi(String text) {
		System.out.println("sayHi called");
		return "Hello " + text;
	}

}

applicationContext.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.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="helloService" implementor="#hello"
		address="/HelloServiceImpl" />
	<bean id="hello" class="org.iteye.bbjava.ws.service.impl.HelloServiceImpl" />
</beans>

web.xml：

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

</context-param>

<listener>
	<listener-class>
		org.springframework.web.context.ContextLoaderListener
	</listener-class>
</listener>

<servlet>
	<servlet-name>CXFServlet</servlet-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>
</web-app>

配置的说明：

<servlet-name>CXFServlet</servlet-name>
	<url-pattern>/*</url-pattern>

上面的url-pattern的作用比较重要，因为CXFServlet会“过虑”关相请求。我们就以上面的代码为例，在浏览器中输入http://localhost:8080/ 会进入webservice相关页面，也就是说在正常的main.jsp它进不去了。

那如何解决呢？
请看:web.xml:

引用

<servlet-name>CXFServlet</servlet-name>
	<url-pattern>/service/ *</url-pattern>

HelloServiceImpl.java:

@WebService(endpointInterface = "org.iteye.bbjava.ws.service.HelloService",targetNamespace = "http://localhost:8080/service")

到此服务端的内容就结束了。
下面是客户端了，

package org.iteye.bbjava.ws;

import org.iteye.bbjava.ws.service.HelloService;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class ClientTest {

	private ClientTest() {
	}

	public static void main(String args[]) throws Exception {
		ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
				new String[] { "applicationContext.xml" });
		HelloService client = (HelloService) context.getBean("helloService");
		String response = client.sayHi("zhang");
		System.out.println("Response: " + response);
	}
}

客户端的：
applicationContext.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="helloService" class="org.iteye.bbjava.ws.service.HelloService"
		factory-bean="clientFactory" factory-method="create" />
	<bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
		<property name="serviceClass"
			value="org.iteye.bbjava.ws.service.HelloService" />
		<property name="address" value="http://localhost:8080/ws-spring/HelloServiceImpl" />
	</bean>
</beans>

配置的说明：

引用

在client.xml:

<property name="address" value="http://localhost:8080/ws-spring/HelloServiceImpl" />

改为

<property name="address" value="http://localhost:8080/ws-spring/service/HelloServiceImpl" />

服务端的applicationContext.xml 细则说明：

引用

<jaxws:endpoint id="helloService" implementor="#hello"  
        address="/HelloServiceImpl" />

jaxws:endpoint 的属性implementor说明 helloService这个接口由hello这个bean实现的。
官方的解释：http://cxf.apache.org/docs/jax-ws-configuration.html，上面写得很清楚，英文好的话建议看一下。

客户端的applicationContext.xml细则说明：

引用

<bean id="helloService" class="org.iteye.bbjava.ws.service.HelloService"
		factory-bean="clientFactory" factory-method="create" />
	<bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
		<property name="serviceClass"
			value="org.iteye.bbjava.ws.service.HelloService" />
		<property name="address" value="http://localhost:8080/ws-spring/HelloServiceImpl" />
	</bean>

上面两行。
两个bean共同组成了一个webserive的接口客户端的核心，其中

<property name="address" value="http://localhost:8080/ws-spring/HelloServiceImpl" />

指出了，服务端的地址。（文字不好组织）
