使用CXF搭建WebServices服务端

1 使用Maven创建Java Web工程，引入cxf和spring，pom.xml如下

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>com.liubo</groupId>
	<artifactId>test-cxf</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>war</packaging>

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>

	<dependencies>
		<dependency>

			<groupId>javax.servlet.jsp</groupId>
			<artifactId>jsp-api</artifactId>
			<version>2.1</version>
			<scope>provided</scope>
		</dependency>
	</dependencies>

	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<version>2.3.2</version>
				<configuration>

				</configuration>
			</plugin>
			<plugin>

					<systemProperties>
						<property>

							<value>target/cobertura/cobertura.ser</value>
						</property>
					</systemProperties>
				</configuration>
			</plugin>
		</plugins>
	</build>
</project>

2 在web.xml中配置applicationContext.xml和cxf servlet

<!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>Archetype Created Web Application</display-name>
	    <context-param>
	        <param-name>contextConfigLocation</param-name>
	        <param-value>classpath:applicationContext.xml</param-value>
	    </context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<servlet>
		<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>
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>

</web-app>

3 创建要提供服务接口和实现

接口类

package com.liubo.test.cxf.service;

import javax.jws.WebParam;
import javax.jws.WebService;

@WebService
public interface HelloWebService {

	String sayHello(@WebParam(name = "text") String text);
}

实现类

package com.liubo.test.cxf.serviceimpl;

import javax.jws.WebParam;
import javax.jws.WebService;

import com.liubo.test.cxf.service.HelloWebService;

@WebService(serviceName = "HelloWS")
public class HelloWebServiceImpl implements HelloWebService {

	public String sayHello(@WebParam(name = "test") String text) {
		System.out.println("sayHello method called");
		return "hello " + text + ", welcome to the real world";
	}

}

4 配置spring文件applicationContext.xml

注意引入xmlns:jaxws和cxf.xml，

xmlns:jaxws="http://cxf.apache.org/jaxws"
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd
http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd

然后添加要提供的接口信息jaxws:endpoint id="HelloWorld"

applicationContext.xml全文如下

<?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:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:util="http://www.springframework.org/schema/util"
	xmlns:jaxws="http://cxf.apache.org/jaxws"
	xmlns:soap="http://cxf.apache.org/bindings/soap/"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
        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://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd
        http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd
    	http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd">

	<!--CXF -->
	<import resource="classpath:META-INF/cxf/cxf.xml" />
	<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
	
	<jaxws:endpoint id="HelloWorld"
		implementor="com.liubo.test.cxf.serviceimpl.HelloWebServiceImpl"
		address="/HelloWS"></jaxws:endpoint>
</beans>

5 配置完成后，部署到tomcat，启动访问http://localhost:8080/test-cxf 即可看到服务已成功发布。

客户端实现见下文：使用cxf-codegen-plugin实现WebServices客户端
