webservice总结之cxf

java webservice有很多种实现方式，处理方式一般有两种:

　　a:基于SOAP的 JAX-WS(Java API for XML-Based Web Services) 比如：RI,Axis,CXF

　　b:基于REST的JAX-RS 比如Jersey，RESTEasy，CXF

可以看到CXF 不仅用于开发基于 SOAP 的 WS，也开发于开发基于 REST 的 WS，那就来总结一下CXF的具体用法吧。

SOAP 风格写法

1，定义接口

import javax.jws.WebService;@WebServicepublic interface HelloFacade {    String sayHello(String msg);}

 

2,服务端实现接口与发布

　a,　实现接口：

import javax.jws.WebService;import org.springframework.stereotype.Component;import com.bresume.core.ws.HelloFacade;@WebService@Componentpublic class HelloFacadeImpl implements HelloFacade{    @Override    public String sayHello(String msg) {        System.out.println("msg="+msg);        return msg+"_success";    }}
HelloFacadeImpl

　b,　web.xml配置:

    <!-- CXF -->    <servlet>        <servlet-name>cxf</servlet-name>        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>    </servlet>    <servlet-mapping>        <servlet-name>cxf</servlet-name>        <url-pattern>/ws/*</url-pattern>    </servlet-mapping>
web.xml

　c,spring配置：

　　最好将ws配置文件单独放置，引入

 <import resource="spring-cxf.xml"/>

　　建立spring-cxf.xml   jaxws:server 或者 jaxws:endpoint 两种配置方式都可以

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"    xmlns:context="http://www.springframework.org/schema/context"    xmlns:jaxws="http://cxf.apache.org/jaxws"    xsi:schemaLocation="http://www.springframework.org/schema/beans                          http://www.springframework.org/schema/beans/spring-beans-3.2.xsd                          http://www.springframework.org/schema/context                          http://www.springframework.org/schema/context/spring-context-3.2.xsd                          http://cxf.apache.org/jaxws                           http://cxf.apache.org/schemas/jaxws.xsd">    <!-- <jaxws:server id="helloFacade" address="/soap/hello">        <jaxws:serviceBean>            <ref bean="helloFacadeImpl" />        </jaxws:serviceBean>    </jaxws:server> -->  <jaxws:endpoint id="helloFacade" implementor="#helloFacadeImpl" address="/soap/hello"/></beans>

服务端配置完毕，访问wsdl，可看到如下内容，则表示服务端配置成功

3，客户端访问

import org.apache.cxf.endpoint.Client;import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;import com.bresume.core.ws.HelloFacade;public class Test {    static final String url = "http://localhost:8081/ws/soap/hello";    public static void main(String[] args) {        testJaxWsClient();        //testDynamicClient();    }    public static void testJaxWsClient () {        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();        factory.setAddress(url);        factory.setServiceClass(HelloFacade.class);        HelloFacade hellofacade = factory.create(HelloFacade.class);        String result = hellofacade.sayHello("word");        System.out.println("testJaxWsClient"+result);    }    public static void testDynamicClient() {        JaxWsDynamicClientFactory  factory = JaxWsDynamicClientFactory .newInstance();        Client client = factory.createClient("http://localhost:8081/ws/soap/hello?wsdl");        try {            Object[] results = client.invoke("sayHello", "world");            System.out.println("DynamicClientFactory"+results[0]);        } catch (Exception e) {            e.printStackTrace();        }    }}
Test
