cxf快速简单的实现webservice调用

webservice的历史和相关技术

参考：http://www.cnblogs.com/doosmile/archive/2012/06/21/2557351.html

webservice技术现在已经非常成熟，大浪淘沙后，目前java开发webservice的框架主要包括axis2和cxf。 

axis2和cxf都是apache旗下的产品，但是其目的不同，导致webservice开发方法也不一样。两个框架都得到了开发者的支持。有必要对二者进行以下对比。

	Axis2	CXF
目标	WebService引擎	简易的SOA框架，可以作为ESB
ws* 标准支持	不支持WS-Policy	WS-Addressing，WS-Policy， WS-RM， WS-Security，WS-I Basic Profile
数据绑定支持	XMLBeans、JiBX、JaxMe 、JaxBRI、ADB	JAXB, Aegis, XMLBeans, SDO, JiBX
spring集成	不支持	支持
应用集成	困难	简单
多语言	支持C/C++	不支持
部署	web应用	嵌入式
服务监控和管理	支持	不支持

结论：

1. 如果希望以一种一致的方式实现webservice，特别是有跨语言的需求时，应该使用Axis2
2. 如果需要在现有的java程序（包括web应用）中增加webservice支持，应该使用CXF

cxf服务端和客户端

 </servlet-mapping>
 </web-app>

spring文件

xml中添加头文件

http://cxf.apache.org/jaxws    

http://cxf.apache.org/schemas/jaxws.xsd    

http://cxf.apache.org/jaxrs    

http://cxf.apache.org/schemas/jaxrs.xsd 

具体实现：

<bean id="greetingServiceImpl" class="com.mycompany.webservice.server.GreetingServiceImpl"/>
 <jaxws:endpoint id="greetingService"  implementor="#greetingServiceImpl"   address="/Greeting" />

接口

package com.mycompany.webservice.server;

import javax.jws.WebService;

@WebService 
public interface Greeting { 
   public String greeting(String userName); 
}

实现类

package com.mycompany.webservice.server;

import java.util.Calendar;
import javax.jws.WebService;

@WebService(endpointInterface = "com.mycompany.webservice.server.Greeting")
public class GreetingServiceImpl implements Greeting {

 public String greeting(String userName) {
  return "Hello " + userName + ", currentTime is "
    + Calendar.getInstance().getTime();
 }
}

客户端

public class GreetingServiceClient {
 public static void main(String[] args) {
  //创建WebService客户端代理工厂
  JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
  //注册WebService接口
  factory.setServiceClass(Greeting.class);
  //设置WebService地址
  factory.setAddress("http://localhost:8080/yourProgramName/webservice/Greeting");
  Greeting greetingService = (Greeting)factory.create();
  System.out.println("invoke webservice...");
  System.out.println("message context is:"+greetingService.greeting("gary"));   
 }
}

解决：jboss本身对soap有管理，因为已经确定问题就是由jboss eap 6.2引起的，所以到jboss配置文件里找到相关配置。

在D:jboss-eap-6.3standaloneconfigurationstandalone.xml中，找到以下代码注释掉。

<!--
        <subsystem xmlns="urn:jboss:domain:webservices:1.2">
            <modify-wsdl-address>true</modify-wsdl-address>
            <wsdl-host>${jboss.bind.address:127.0.0.1}</wsdl-host>
            <endpoint-config name="Standard-Endpoint-Config"/>
            <endpoint-config name="Recording-Endpoint-Config">
                <pre-handler-chain name="recording-handlers" protocol-bindings="##SOAP11_HTTP ##SOAP11_HTTP_MTOM ##SOAP12_HTTP ##SOAP12_HTTP_MTOM">
                    <handler name="RecordingHandler" class="org.jboss.ws.common.invocation.RecordingServerHandler"/>
                </pre-handler-chain>
            </endpoint-config>
            <client-config name="Standard-Client-Config"/>
        </subsystem>
         -->

虽然是6.3的版本，还是一样的问题  具体参考

cxf客户端调用问题 

问题如：Unsupported major.minor version 51.0 异常 

具体参考： https://segmentfault.com/q/1010000002930567

原因：cxf 3.1.6 已经不支持jdk1.6

解决办法： 修改当前引用jdk为1.7 问题解决
