CXF 发布 Java webservice

1 服务端

服务端使用了 JAX-WS API 开发，并使用 CXF 发布，同时使用 Spring context 管理 bean 。由于发布到 Tomcat 服务器，所以要 “cxf-rt-transports-http”。

定义 SEI

接口类，可要可不要

package com.cheery.recruitment.ws;import javax.jws.WebService;@WebServicepublic interface HelloWorld {    String sayHi(String text);}

实现类，它才是真正的 Service Endpoint

package com.cheery.recruitment.ws;import javax.jws.WebService;@WebService(endpointInterface = "com.cheery.recruitment.ws.HelloWorld")public class HelloWorldImpl implements HelloWorld {    public String sayHi(String text) {        System.out.println("sayHi called");        return "Hello " + text;    }}

使用 spring 管理服务bean

在 webapp 目录下创建文件：WEB-INF/beans.xml

<?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:jaxws="http://cxf.apache.org/jaxws"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd        http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">    <jaxws:endpoint id="helloWorld" implementor="com.cheery.recruitment.ws.HelloWorldImpl"        address="/HelloWorld" /></beans>

web.xml

定义 CXFServlet ，当然也要初始化 web 应用上下文

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns="http://java.sun.com/xml/ns/javaee"    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"    version="3.0">    <display-name>recruitment</display-name>    <context-param>      <param-name>contextConfigLocation</param-name>      <param-value>WEB-INF/beans.xml</param-value>   </context-param>   <listener>      <listener-class>         org.springframework.web.context.ContextLoaderListener      </listener-class>   </listener>   <servlet>      <servlet-name>CXFServlet</servlet-name>            <servlet-class>         org.apache.cxf.transport.servlet.CXFServlet      </servlet-class>      <load-on-startup>1</load-on-startup>   </servlet>   <servlet-mapping>      <servlet-name>CXFServlet</servlet-name>      <url-pattern>/*</url-pattern>   </servlet-mapping></web-app>

部署Tomcat 并测试

浏览器地址：http://localhost:8080/recruitment/HelloWorld?wsdl
可以看到该服务资源的 wsdl 则表示发布成功。

2 使用 CXF 下载代码

C:\Users\z15075>d:D:\>cd D:\apache-cxf-3.1.12\binD:\apache-cxf-3.1.12\bin>wsdl2java -encoding utf-8 -p com.cheery.recruitment.ws -d D:\work\ http://localhost:8080/recruitment/HelloWorld?wsdl

3 客户端

将步骤2 的代码复制到 src 下

略

也用 spring 管理客户端bean吧

<?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:jaxws="http://cxf.apache.org/jaxws"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd        http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">    <jaxws:client id="helloWorldClient" serviceClass="com.cheery.recruitment.ws.HelloWorld"        address="http://localhost:8080/recruitment/HelloWorld" /></beans>

像使用本地方法一样调用 webservice

package com.cheery.recruitment;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.cheery.recruitment.ws.HelloWorld;public class Client {    public static void main(String[] args) {        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[]                 {"classpath:META-INF/beans.xml"});        HelloWorld helloWorldClient=(HelloWorld) context.getBean("helloWorldClient");        String msg_retrun=helloWorldClient.sayHi("Java web service");        System.out.println(msg_retrun);    }}

4 总结

核心，JAX-WS API ，CXF frontend
