Maven:

<!-- WebService -->
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-frontend-jaxws</artifactId>
            <version>3.0.4</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-transports-http</artifactId>
            <version>3.0.4</version>
        </dependency>
        <dependency>
            <groupId>org.apache.neethi</groupId>
            <artifactId>neethi</artifactId>
            <version>3.0.3</version>
        </dependency>

这里的org.apache.neethi的版本最好是3.0.3   不然你使用了别人的webservice可能会报错   我试过用3.0.2报错
: javax.wsdl.WSDLException: WSDLException: faultCode=PARSER_ERROR: java.lang.RuntimeException: Cannot create a secure XMLInputFactory

具体原因不清楚

还有记得别加这个

不然还是报错 

Caused by: org.apache.cxf.BusException: No DestinationFactory was found for the namespace http://schemas.xmlsoap.org/soap/http.

webxml:

<servlet>
        <servlet-name>CXFService</servlet-name>
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>CXFService</servlet-name>
        <url-pattern>/ws/*</url-pattern>
    </servlet-mapping>

url-pattern自定义，就是你访问webservice的地址

Springxml:

<!-- 接口的实现类声明 -->
    <bean id="自定义" class="写你webservice接口的实现类" />

    <!-- 默认自带日志输出 -->
    <bean id="inMessageInterceptor" class="org.apache.cxf.interceptor.LoggingInInterceptor" />
    <bean id="outLoggingInterceptor" class="org.apache.cxf.interceptor.LoggingOutInterceptor" />

    <!-- 发布WebService -->
    <jaxws:server id="自定义" serviceClass="这里写你接口不是实现类"
        address="/自定义访问webservice的地址">
        <jaxws:serviceBean>
            <ref bean="自定义接口的实现类" />
        </jaxws:serviceBean>
        <jaxws:inInterceptors>
            <ref bean="inMessageInterceptor" />
        </jaxws:inInterceptors>
        <jaxws:outInterceptors>
            <ref bean="outLoggingInterceptor" />
        </jaxws:outInterceptors>
    </jaxws:server>

webservice接口:

package ws.spring.server;  
  
import javax.jws.WebMethod;  
import javax.jws.WebService;  
  
@WebService  
public interface UserWS {  
    @WebMethod  
    public UserBean getUserById(int id);  
}

webservice实现类 ：

package ws.spring.server;  
  
import javax.jws.WebService;  
  
@WebService  
public class UserWSImpl implements UserWS {  
    public UserWSImpl(){  
        System.out.println("初始化 UserWSImpl");  
    }  
    @Override  
    public UserBean getUserById(int id) {  
        System.out.println("server getUserById:"+id);  
        return new UserBean(1, "张三");  
      
    }  
  
}

运行输入地址: /ws/自定义的webservice 地址
