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

                </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
