上一节中使用代理工厂 JaxWsProxyFactoryBean 来发布 WebService, 这种方式必须指定运行的端口，如果端口被占用，就会发布失败。

cxf 的 WebService 也可利用 Tomcat 来发布，并且使用 8080 端口。方法如下：

maven 配置：

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <spring.version>4.3.0.RELEASE</spring.version>
        <cxf.version>3.0.3</cxf.version>
    </properties>

在 web.xml 中加入以下配置 (spring 监听器和 cxf 的 servlet)：

<listener>
        <description>SpringListener</description>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:applicationContext.xml</param-value>
    </context-param>
    <!--cxf 的 Servlet-->
    <servlet>
        <servlet-name>CXFServlet</servlet-name>
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>CXFServlet</servlet-name>
        <url-pattern>/ws/*</url-pattern>
    </servlet-mapping>

接口：

@WebService
public interface HelloService{public String helloCxf();

    public String hello(String name);

    public User getUser(int id);

    public void saveUser(User user);
}

实现类：

@WebService(serviceName = "helloService",
        endpointInterface = "cn.lg.ws.hellocxf.HelloService"
)
public class HelloServiceImpl implements HelloService{

    @Override
    public String helloCxf(){return "Hello CXF!";
    }

    @Override
    public String hello(String name)
    {return "Hello" + name;
    }

    @Override
    public User getUser(int id) {User user = new User();
        user.setId(id);
        user.setName("lg");
        user.setEmail("QQ");
        user.setAddress("hahaha");
        return user;
    }

    @Override
    public void saveUser(User user) {System.out.println(user.toString());
    }

}
