一.简介
Apache CXF是一个开源的Service框架,可以用于简化用户的service开发,基于CXF开发的应用可提供SOAP、XML/HTTP、RESTFUL HTTP或CORBA等服务。CXF底层页可以使用不同的传输协议,包括HTTP、JMS或JBI等。
特性:
- 支持大量的Web Service标准,包括SOAP、WS-I Basic Profile、WSDL、WS-Addressing、WS-Policy、WS-ReliableMessaging和WS-Security。
- CXF支持大量的前端(frontend)编程模型。CXF实现了标准的JAX-WS API,它也包括一种被称为简单前端(simple frontend)的模型,这种模型无需annotation支持。CXF支持web service的两种开发模式:①规则(contract)优先的开发模式,即通过编写WSDL来开发web service;②代码优先的开发模式,即通过编写java代码来开发webservice.
二.下载与安装(非maven)
Web Service注释介绍
四.入门案例(maven方法)
1.新建一个maven项目,在pom中添加依赖和jetty作为测试的web service的web容器。

2.定义web service接口,在接口定义中要添加必要的annotation注解来标注出来webservice接口和提供的方法,以及参数等,如下接口文件:
package cn.outofmemory.hello.apache.cxf;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
@WebService
public interface HelloService {
@WebMethod//方法
//@WebResult 返回类型
public @WebResult String hello(@WebParam(name="who") String who);//如果不修改参数名称,那wsdl中默认是arg0
}
3.实现接口:
package cn.outofmemory.hello.apache.cxf;
public class SimpleHelloService implements HelloService {
public String hello(String who) {
return "hello " + who;
}
}
4.在web容器中运行web Service:
package cn.outofmemory.hello.apache.cxf;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;
public class Server {
public static void main(String[] args) throws Exception {
JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();
factory.setServiceClass(SimpleHelloService.class);
factory.setAddress("http://localhost:9000/ws/HelloService");
factory.create();
System.out.println("Server start...");
}
}
可以运行这个类,然后再浏览器中访问:http://localhost:9000/ws/HelloService?wsdl
可以让Server端保持启动状态,下面我们写Client端来调用server端的webservice,如下client端代码:
5.客户端代码如下:
package cn.outofmemory.hello.apache.cxf;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
public class ServiceClient {
public static void main(String[] args) {
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(HelloService.class);
factory.setAddress("http://localhost:9000/ws/HelloService");
HelloService helloworld = (HelloService) factory.create();
System.out.println(helloworld.hello("outofmemory.cn"));
System.exit(0);
}
}
运行client,可以得到hello outofmemory.cn的输出。
