WebService整合spring

前言

关于webservice的理论不再叙述了，见我前两篇博客，这里以一个简单的例子，叙述cxf和spring的整合。

服务端

webservice对外接口
webservice作为服务对外发布的时候，暴露的都是一个接口，这里一个HelloWorld为例，这个接口中只包含一个sayHello方法。

import javax.jws.WebService;@WebServicepublic interface HelloWorld {    public String  sayHello(String name);}

webservice接口实现
接口实现类也很简单，只是将输入的name，进行简单输出。

import javax.jws.WebService;@WebServicepublic class HelloWorldImpl implements HelloWorld {    public String  sayHello(String name) {        return "Hello World"+name;    }}

发布
编写好服务端代码后，就可以将其作为服务发布，这里我们选择结合spring进行。利用jaxws:endpoint元素发布服务。

<?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:jaxws="http://cxf.apache.org/jaxws"      xmlns:cxf="http://cxf.apache.org/core"      xsi:schemaLocation="http://www.springframework.org/schema/beans       http://www.springframework.org/schema/beans/spring-beans-2.5.xsd       http://cxf.apache.org/jaxws       http://cxf.apache.org/schemas/jaxws.xsd">      <import resource="classpath:META-INF/cxf/cxf.xml" />      <jaxws:endpoint id="helloWorld" implementor="com.sf.webservice.HelloWorldImpl" address="/HelloWorld"/></beans><!-- END SNIPPET: beans -->

这里implementor是指服务的实现类，address是服务的地址，客户端后面要通过这个地址访问。

客户端

客户端我们同样结合spring进行，利用jaxws:client元素声明。

<?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:aop="http://www.springframework.org/schema/aop"    xmlns:tx="http://www.springframework.org/schema/tx" 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-3.0.xsd           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd              http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">              <jaxws:client id="client" address="http://localhost:8081/webservice/HelloWorld"        serviceClass="com.sf.webservice.HelloWorld" /></beans>

这里address是服务发布的地址，其中webservice是我的项目名称。serviceClass是服务端的对外服务接口。
这里我们客户端用个main函数来测试我们的项目是否成功。

package com.sf.webservice;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class HelloWorldClient {        public static void main(String args[]) throws Exception {             ApplicationContext ctx = new ClassPathXmlApplicationContext("client-beans.xml");               HelloWorld client = (HelloWorld) ctx.getBean("client");                  String result = client.sayHello("你好!");                  System.out.println(result);          }}

我们的项目是个maven工程，这里给出相应的maven配置。
