cxf spring webservice

首先，新建项目名为cxf_Spring，

拷贝所需jar包至lib目录，CXF和spring整合需要准备如下jar包文件,目录结构的截图如附件中的1.jpg文件：

web.xml的配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>

	<!-- 加载Spring容器配置 -->
	<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>

	<!-- 设置Spring容器加载配置文件路径 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath*:applicationContext**.xml</param-value>
	</context-param>

	<listener>
		<listener-class>
			org.springframework.web.util.IntrospectorCleanupListener
		</listener-class>
	</listener>

	<!-- CXF配置 -->
	<servlet>
		<servlet-name>CXFService</servlet-name>
		<servlet-class>
			org.apache.cxf.transport.servlet.CXFServlet
		</servlet-class>
	</servlet>

	<servlet-mapping>
		<servlet-name>CXFService</servlet-name>
		<url-pattern>/*</url-pattern>
	</servlet-mapping>

</web-app>

然后在src目录中，新建一个applicationContext-server.xml文件，文件内容如下：

下面开始写服务器端代码，实体操作bean的代码如下：

package com.wxl.bean;

public class User {

	private Integer id;
	private String name;
	private String email;
	private String address;

	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getEmail() {
		return email;
	}

	public void setEmail(String email) {
		this.email = email;
	}

	public String getAddress() {
		return address;
	}

	public void setAddress(String address) {
		this.address = address;
	}

	@Override
	public String toString() {
		return "id:" + this.id + " name:" + this.name + " email:" + this.email
				+ " address:" + this.address;
	}

}

首先定制服务器端的接口，代码如下：

package com.wxl.server.service;

import javax.jws.WebParam;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;

import com.wxl.bean.User;

/**
 * 定制客户端请求WebService所需要的接口
 * 
 * @author wangxl
 * 
 */
@WebService
@SOAPBinding(style = Style.RPC)
public interface IComplexUserService {
	public User getUserByName(@WebParam(name = "name")
	String name);

	public void setUser(User user);

}

下面编写WebService接口的实现类，代码如下：

package com.wxl.server.service.impl;

import java.util.Date;

import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;

import com.wxl.bean.User;
import com.wxl.server.service.IComplexUserService;

@WebService
@SOAPBinding(style = Style.RPC)
@SuppressWarnings("deprecation")
public class ComplexUserServiceImpl implements IComplexUserService {

	public User getUserByName(String name) {
		User user = new User();
		user.setId(new Date().getSeconds());
		user.setName(name);
		user.setEmail(name + "@yahoo.cn");
		user.setAddress("Chian");
		return user;
	}

	public void setUser(User user) {
		System.out.println("############Server setUser###########");
		System.out.println("setUser:" + user);
	}

}

注意的是和Spring集成，这里一定要完成接口实现，如果没有接口的话会有错误的。

下面要在applicationContext-server.xml文件中添加如下配置：

<!-- 注入接口实现类 -->
	<bean id="userServiceBean"
		class="com.wxl.server.service.impl.ComplexUserServiceImpl" />
	
	<!-- 日志拦截器 -->
	<bean id="inMessageInterceptor"
		class="org.apache.cxf.interceptor.LoggingInInterceptor">
		<constructor-arg value="receive" />
	</bean>

	<bean id="outLoggingInterceptor"
		class="org.apache.cxf.interceptor.LoggingOutInterceptor" />

	<!-- 注意下面的address，这里的address的名称就是访问的WebService的name -->
	<jaxws:server id="userService"
		serviceClass="com.wxl.server.service.IComplexUserService"
		address="/users">
		<jaxws:serviceBean>
			<!-- 要暴露的 bean 的引用 -->
			<ref bean="userServiceBean" />
		</jaxws:serviceBean>

		<jaxws:inInterceptors>
			<ref bean="inMessageInterceptor" />
		</jaxws:inInterceptors>
		<jaxws:outInterceptors>
			<ref bean="outLoggingInterceptor" />
		</jaxws:outInterceptors>
	</jaxws:server>

下面将项目部署到tomcat，启动tomcat服务器后，在浏览器中请求如下地址：

http://localhost:8088/cxf_Spring/users?wsdl

如果你能看到wsdl的xml文件的内容，就说明你成功了，注意的是上面地址的users就是上面xml配置中的address的名称，是一一对应的。

下面编写客户端请求的代码，代码如下：

package com.wxl.client.test;

import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.wxl.bean.User;
import com.wxl.server.service.IComplexUserService;

//client端java的实现
public class UserWSClient {

	public static void main(String[] args) {
		 new UserWSClient().WSClientTest();
	}

	public void WSClientTest() {
		// 调用WebService
		JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
		factory.setServiceClass(IComplexUserService.class);
		factory.setAddress("http://localhost:8088/cxf_Spring/users");
		// 添加日志拦截器
		factory.getInInterceptors().add(new LoggingInInterceptor());// 请求的
		factory.getOutInterceptors().add(new LoggingOutInterceptor());// 发送出去的
		IComplexUserService service = (IComplexUserService) factory.create();
		System.out.println("#############JAxWs Client getUserByName##############");
		User user = service.getUserByName("wxl");
		System.out.println(user.toString());
		user.setAddress("China-Hangzhou");
		service.setUser(user);
	}

}

在main函数中调用WSClientTest()方法，运行后可以在控制台中看到如下信息：

这个server端是通过Spring整合配置的，client端是我们手动访问发布的地址来实现访问。下面我们将Client端也通过Spring配置完成整合。

首先在src下增加applicationContext-client.xml配置文件，文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:jaxws="http://cxf.apache.org/jaxws"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.0.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" />

	<!-- client端的spring实现 -->
	<jaxws:client id="userWsClient"
		serviceClass="com.wxl.server.service.IComplexUserService"
		address="http://localhost:8088/cxf_Spring/users">
	</jaxws:client>

</beans>

在客户端UserWSClient类中添加一个Spring实现的方法，请求代码如下：

public void springWsClientTest() {

		ApplicationContext ctx = new ClassPathXmlApplicationContext(
				"applicationContext-client.xml");
		IComplexUserService service = ctx.getBean("userWsClient",
				IComplexUserService.class);

		System.out
				.println("#############Spring Client getUserByName##############");
		User user = service.getUserByName("wxl");
		System.out.println(user.toString());

		user.setAddress("China-Hangzhou");
		service.setUser(user);

	}

在main函数中运行 springWsClientTest()方法后，结果如下：

log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.
