CXF中服务发布与访问方式

?? apache CXF实现了JAX-WS和JAX-RS Web服务范围，所以在CXF中，基于传统soap协议与restful风格的Web服务都支持。而且在CXF中Web服务的发布与访问 也有多种方式，这里就列举一下并做简要说明，下面是示例服务接口与服务实现类：

@WebService
@Produces("text/plain")
public interface HelloService {
	@GET @Path("/{name}")
	String sayHello(@PathParam("name")@WebParam(name="name")String name);
}
public class HelloServiceImpl implements HelloService {

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

}

为了重用接口，就把soap协议服务与restful服务的相关注解标在同一个接口上，package均为com.nightsoul.cxf。

服务端：

public class ServerTest {
	public static final String ADDRESS = "http://127.0.0.1:9000/hello";
	
	/**
	方式一、使用JDK中的API
			使用这种方式时，JDK版本应该是不能低于JDK1.6.0_21，如果运行报错，应该就是JDK版本的问题
	**/
	@Test
	public void testEndpoint() throws Exception {
		//第一个参数为服务发布地址，第二个为服务实现类对象
		Endpoint.publish(ADDRESS,new HelloServiceImpl());
	}
	
	/**
	方式二、使用JaxWsServerFactoryBean
	**/
	@Test
	public void testJaxWsServerFactoryBean() throws Exception {
		JaxWsServerFactoryBean factoryBean = new JaxWsServerFactoryBean();
		factoryBean.setAddress(ADDRESS);
		factoryBean.setServiceClass(HelloService.class);
		factoryBean.setServiceBean(new HelloServiceImpl());
		factoryBean.create();
	}
	
	/**
	方式三、使用Simple FrontEnd
			这种方式基本与方式二一样
	**/
	@Test
	public void testSimpleFrontEnd() {
		ServerFactoryBean factoryBean = new ServerFactoryBean();
		factoryBean.setAddress(ADDRESS);
		factoryBean.setServiceClass(HelloService.class);
		factoryBean.setServiceBean(new HelloServiceImpl());
		factoryBean.create();
	}
	
	/**
	方式四、将Web服务配置在Spring中
			当类路径下含有Spring时，CXF中的Bus会自动使用SpringBus实现类，从而会自动加载类路径下META-INF/cxf/cxf.xml与cxf.xml
			文件，只要将服务Bean进行简单配置即可，JAXWS与JAXRS均支持
			<jaxws:endpoint implementor="com.nightsoul.cxf.HelloServiceImpl" address="http://127.0.0.1:9000/hello"></jaxws:endpoint>
			<jaxrs:server serviceClass="com.nightsoul.cxf.HelloServiceImpl" address="http://127.0.0.1:9000/hello"></jaxrs:server>
	**/
	@Test
	public void testSpring() throws Exception {
		SpringBusFactory factory = new SpringBusFactory();
		factory.createBus();
	}
	
	
	/**
	方式五、使用restful形式
			@Produces注解用于表明服务返回的结果内容类型，@GET表示该方法只能通过get方式进行访问
			@Path为该方法的路径，而完整的访问路径为JAXRSServerFactoryBean绑定的路径加上@Path配置的路径
			例如：http://127.0.0.1:9000/hello/zhangsan，则name参数值为zhangsan
	**/
	@Test
	public void testJaxRsServerFactoryBean() throws Exception {
		JAXRSServerFactoryBean factoryBean = new JAXRSServerFactoryBean();
		factoryBean.setResourceClasses(HelloServiceImpl.class);
		factoryBean.setBindingId(JAXRSBindingFactory.JAXRS_BINDING_ID);
		factoryBean.setAddress(ADDRESS);
		factoryBean.create();
	}
	
	
	@After
	public void after() throws Exception {//防止服务端退出
		Object object = new Object();
		synchronized (object) {
			object.wait();
		}
	}
}

客户端：

public class ClientTest {
	
	/**
	方式一、使用JDK中的API
	**/
	@Test
	public void testEndpoint() throws Exception {
		QName helloName = new QName("http://cxf.nightsoul.com/","HelloServicePort");
		Service service = Service.create(helloName);
		service.addPort(helloName,SOAPBinding.SOAP11HTTP_BINDING,ServerTest.ADDRESS);
		HelloService helloService = service.getPort(HelloService.class);
		System.out.println(helloService.sayHello("xtayfjpk"));
	}
	
	/**
	方式二、使用JaxWsProxyFactoryBean
	**/
	@Test
	public void testJaxWsProxyFactoryBean() throws Exception {
		JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();
		factoryBean.setAddress(ServerTest.ADDRESS);
		factoryBean.setServiceClass(HelloService.class);
		HelloService helloService = factoryBean.create(HelloService.class);
		System.out.println(helloService.sayHello("xtayfjpk"));
	}
	
	/**
	方式三、使用JaxWsClientFactoryBean
	**/
	@Test
	public void testJaxWsClientFactoryBean() throws Exception {
		JaxWsClientFactoryBean bean = new JaxWsClientFactoryBean();
		bean.setAddress(ServerTest.ADDRESS);
		bean.setServiceClass(HelloService.class);
		bean.create().invoke("sayHello","xtayfjpk");
	}
	
	/**
	方式四、使用Simple FrontEnd
	**/
	@Test
	public void testSimpleFrontEnd() {
		ClientProxyFactoryBean factoryBean = new ClientProxyFactoryBean();
		HelloService helloService = factoryBean.create(HelloService.class);
		System.out.println(helloService.sayHello("xtayfjpk"));
	}

	/**
	方式五、将wsdl文件生成java类
			使用cxf提供的wsdl2java工具会生成客户端调用类，将其加入类路径下，这种方式只对soap服务有效
	**/
	@Test
	public void testWsdl2Java() {
		HelloServiceService service = new HelloServiceService();
		System.out.println(service.getPort(HelloService.class).sayHello("xtayfjpk"));
	}
	
}

对于restful风格的Web服务，其访问方式与普通URL无差别，直接在浏览器中访问地址即可，如果愿意的话也可以使用HttpClient。
