第三方jar@CXF

CXF基于JAX-WS进行了功能的扩展，提供了更加方便的API进行webservice的开发

了解JAX-WS的基本知识对学习CXF很有帮助，尤其是SOAP协议中消息如何传递得比较清楚才行

学习CXF提供的第一个直观的好处：方便输出客户端与服务端交互的SOAP消息

使用Interceptor实现消息的输出，这样便于查看具体消息是如何传递的，也便于排查问题

服务端：

接口

package com.hqh.ws.cxf;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

@WebService
public interface IMyService {

	@WebMethod
	@WebResult(name="sayResult")
	public String sayHello(@WebParam(name="name") String name,
			@WebParam(name="license", header=true) String license);
}

实现类

package com.hqh.ws.cxf;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService(endpointInterface="com.hqh.ws.cxf.IMyService")
public class MyServiceImpl implements IMyService {

	@Override
	@WebMethod
	public String sayHello(String name,String license) {
		return (license==null||"".equals(license.trim())) ? "头信息为空" : "你好："+name ;
	}

}

启动服务

package com.hqh.ws.cxf;

import javax.xml.ws.Endpoint;

import org.apache.cxf.endpoint.Server;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

public class MyServer {

	public static void main(String[] args) {
		//startServer();
		startServerByCXF(); 
	}
	/**
	 * 基于JAX-WS的方式发布服务
	 * @param args
	 */
	public static void startServer() {
		Endpoint.publish("http://localhost:8888/cxf/ws", new MyServiceImpl());
	}
	
	/**
	 * 使用CXF发布服务
	 */
	public static void startServerByCXF() {
		JaxWsServerFactoryBean svrFactory = new JaxWsServerFactoryBean();
		svrFactory.setServiceClass(IMyService.class);
		svrFactory.setAddress("http://localhost:8888/cxf/ws");
		svrFactory.setServiceBean(new MyServiceImpl());
		//打印发出的消息
		svrFactory.getInInterceptors().add(new LoggingInInterceptor());
		//打印进入的消息
		svrFactory.getOutInterceptors().add(new LoggingOutInterceptor());
		svrFactory.create();
	}
}
