        // 手动创建webClient对象，注意这里的地址是发布的那个/rest地址

        //String url = "http://localhost:8000/CXFWebService/rest/";

    }

        User user = new User();

        user.setId(21432134);

        user.setAddress("hoojo#gz");

        user.setEmail("hoojo_@126.com");

        user.setName("hoojo");

        System.out.println(client.path("sample/postData").accept(MediaType.APPLICATION_XML).post(user, User.class));

    }

    @Test

    }

}

<?xml version="1.0" encoding="UTF-8"?>

    <bean id="webClient" class="org.apache.cxf.jaxrs.client.WebClient" factory-method="create">

        <constructor-arg type="java.lang.String" value="http://localhost:8000/CXFWebService/rest/" />

    </bean>

</beans>

这种是利用WebClient对象来调用WebService，还有一种方法也可以调用WebService，代码如下：

// 手动创建

//RESTSample sample = JAXRSClientFactory.create("http://localhost:8000/CXFWebService/rest", RESTSample.class);

// 从Spring Ioc容器中拿webClient对象

ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-client.xml");

RESTSample sample = ctx.getBean("restSampleBean", RESTSample.class);

System.out.println(sample);

System.out.println(sample.doGet());

//System.out.println(sample.doRequest("haha", null, null));

System.out.println(sample.getBean(22));

System.out.println(sample.getList());

System.out.println(sample.getMap().getMap());

User user = new User();

user.setId(21432134);

user.setAddress("hoojo#gz");

user.setEmail("hoojo_@126.com");

user.setName("hoojo");

System.out.println(sample.postData(user));

System.out.println(sample.putData(111, user));

sample.deleteData(2);

这种方式相对比WebClient要简单，直接使用接口中的方法即可。同样如果你要整合到Spring可以在applicationContext-client.xml中增加配置如下：

<bean id="restSampleBean" class="org.apache.cxf.jaxrs.client.JAXRSClientFactory" factory-method="create">

    <constructor-arg type="java.lang.String" value="http://localhost:8000/CXFWebService/rest/" />

    <constructor-arg type="java.lang.Class" value="com.hoo.service.RESTSample" />

</bean>

执行以上方法可以看到控制台打印结果如下：

client console

org.apache.cxf.jaxrs.client.ClientProxyImpl@1cf7491

this is get rest request

22#JojO#null#null

com.hoo.entity.Users@16eb6bc

{key-0=0#JojO-0#null#null, key-1=1#JojO-1#null#null, key-2=2#JojO-2#null#null, key-3=3#JojO-3#null#null}

21432134#jojo##12321321#hoojo_@126.com#hoojo#gz

111#hoojo#hoojo_@126.com#hoojo#gz

就这样，整合restful WebService成功。
