结合spring框架来实现CXF发布SOAP协议的服务，步骤基本相同，所不同的是的多了一些配置项，步骤如下。

1.服务器程序

创建一个web工程
导入依赖包

<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.webservice.demo</groupId>
  <artifactId>Server1</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>war</packaging>

  <!-- 集中定义依赖版本号 -->
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.7</maven.compiler.source>
    <maven.compiler.target>1.7</maven.compiler.target>

    <junit.version>4.12</junit.version>
    <spring.version>4.3.8.RELEASE</spring.version>
    <cxf.version>3.2.6</cxf.version>

  </properties>

  <dependencies>

    <!-- 单元测试 -->
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>${junit.version}</version>
      <scope>test</scope>
    </dependency>

    <!-- Spring -->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-beans</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jdbc</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-aspects</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-tx</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-test</artifactId>
      <version>${spring.version}</version>
    </dependency>

    <dependency>
      <groupId>org.apache.cxf</groupId>
      <artifactId>cxf-core</artifactId>
      <version>${cxf.version}</version>
    </dependency>

    <dependency>
      <groupId>org.apache.cxf</groupId>
      <artifactId>cxf-rt-frontend-jaxws</artifactId>
      <version>3.2.6</version>
    </dependency>
    <dependency>
      <groupId>org.apache.cxf</groupId>
      <artifactId>cxf-rt-transports-http</artifactId>
      <version>3.2.6</version>
    </dependency>

  </dependencies>
  
</project>

（3）拷贝cxf开发的java工程的代码到web工程中：

@WebService
@BindingType(SOAPBinding.SOAP12HTTP_BINDING)
public interface WeatherInterface {

  public String queryWeather(String cityName);
}


public class WeatherInterfaceImpl implements WeatherInterface {
  @Override
  public String queryWeather(String cityName) {
    if ("成都".equals(cityName)) {
      return "冷且霾";
    } else {
      return "暖且晴";
    }
  }
}

（4）配置Spring配置文件 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"
       xmlns:jaxrs="http://cxf.apache.org/jaxrs"
       xmlns:cxf="http://cxf.apache.org/core"
       xsi:schemaLocation="http://www.springframework.org/schema/beans 
                    http://www.springframework.org/schema/beans/spring-beans.xsd
                    http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.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">
                         
  <!--jaxws:server发布SOAP协议的服务 ，对JaxWsServerFactoryBean类封装 -->
  <!-- 
    发布一个服务
      id="aa"：表示惟一标识
      address:表示发布服务的项目地址,weatherServer此时就表示访问url的时候，在?wsdl之前要存在weatherServer，也就是weatherServer?wsdl
      serviceClass:表示指定发布服务的接口的路径
   -->
  <jaxws:server serviceClass="com.webservice.demo.WeatherInterface" address="/weather">
    <jaxws:serviceBean>
      <ref bean="weatherInterface" />
    </jaxws:serviceBean>
    <!--配置拦截器 -->
    <jaxws:inInterceptors>
      <ref bean="inInterceptor" />
    </jaxws:inInterceptors>
    <jaxws:outInterceptors>
      <ref bean="outInterceptor" />
    </jaxws:outInterceptors>
  </jaxws:server>
  
  <!-- 配置服务实现类 -->
  <bean name="weatherInterface" class="com.webservice.demo.WeatherInterfaceImpl"></bean>
  
  <!--配置拦截器bean -->
  <bean name="inInterceptor" class="org.apache.cxf.interceptor.LoggingInInterceptor"/>
  <bean name="outInterceptor" class="org.apache.cxf.interceptor.LoggingOutInterceptor"/>
</beans>

（5）第五步：配置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"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
  id="WebApp_ID" version="3.0">
  <display-name>D</display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <!-- 添加Spring的上下文环境监听 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!-- 配置CXF的Servlet -->
  <servlet>
    <servlet-name>CXF</servlet-name>
    <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>CXF</servlet-name>
    <url-pattern>/ws/*</url-pattern>
  </servlet-mapping>

</web-app>

第六步：启动tomcat,部署web工程到tomcat
第七步：测试服务是否发布成功

WSDL地址规则：http://localhost:端口号/项目名称/servlet拦截路径/服务名称?wsdl

2.客户端程序

第一步：创建web工程作为客户端，引入cxf的jar包
第二步：生成客户端代码
执行命令：wsdl2java -p 包名－d . 服务说明书地址
示例：
wsdl2java -p com.webservice.client -d .http://localhost:8080/Server1/ws/weather?wsdl
第三步：配置spring的配置文件

<?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"
  xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:cxf="http://cxf.apache.org/core"
  xsi:schemaLocation="http://www.springframework.org/schema/beans 
                    http://www.springframework.org/schema/beans/spring-beans.xsd
                    http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.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">

  <!--jaxws:client实现客户端配置,对JaxWsProxyFactoryBean类封装 -->
  <jaxws:client id="weatherClient" address="http://127.0.0.1:8080/Server1/ws/weather"
    serviceClass="com.webservice.client.WeatherInterface"></jaxws:client>

</beans>

第四步：初始化spring上下文，获取接口实现类，调用查询方法

public class WeatherClient {

  public static void main(String[] args) {
    ApplicationContext context = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
    WeatherInterface weatherInterface = (WeatherInterface) context.getBean("weatherClient");
    System.out.println(weatherInterface.queryWeather("北京"));
  }
}
