Apache CXF 学习笔记二，创建第一个基于JAX-WS的简单Sample

该Sample实际上就是把Apache CXF官方网站的A Simple JAX-WS Service依葫芦画瓢走了一遍，没有太多东东，这里仅仅是记录下来已方便自己回忆。这里我使用Eclipse作为开发工具。

根据官方网站可以把这个Sample分成四部分来完成，所以我这里也按照这四部分来记录：

1. 搭建Apache CXF环境

a) 创建一个新的Java Project
b) 添加相关的jar包，所有的jar包都可以在CXF官方下载站点的apache-cxf-2.2.8.zip下载包里找到.
CXF依赖的jar包：
commons-logging-1.1.1.jar
geronimo-activation_1.1_spec-1.0.2.jar (or Sun's Activation jar)
geronimo-annotation_1.0_spec-1.1.1.jar (JSR 250)
geronimo-javamail_1.4_spec-1.6.jar (or Sun's JavaMail jar)
geronimo-servlet_2.5_spec-1.2.jar (or Sun's Servlet jar)
geronimo-ws-metadata_2.0_spec-1.1.2.jar (JSR 181)
geronimo-jaxws_2.1_spec-1.0.jar (or Sun's jaxws-api-2.1.jar)
geronimo-stax-api_1.0_spec-1.0.1.jar (or other stax-api jar)
jaxb-api-2.1.jar
jaxb-impl-2.1.12.jar
jetty-6.1.21.jar
jetty-util-6.1.21.jar
neethi-2.0.4.jar
saaj-api-1.3.jar
saaj-impl-1.3.2.jar
wsdl4j-1.6.2.jar
wstx-asl-3.2.8.jar
XmlSchema-1.4.5.jar
xml-resolver-1.2.jar
Spring依赖的jar包：
aopalliance-1.0.jar
spring-core-2.5.5.jar
spring-beans-2.5.5.jar
spring-context-2.5.5.jar
spring-web-2.5.5.jar
CXF的jar包：
cxf-2.2.3.jar
2. 编写Service端代码

a) Service端接口类：

import javax.jws.WebParam;
import javax.jws.WebService;

@WebService
public interface HelloService {
public String sayHello(@WebParam(name="text")String text);
}

b) Service端实现类：

import javax.jws.WebService;

@WebService
public class HelloServiceImpl implements HelloService {
public String sayHello(String text) {
return "Hello ".concat(text);
}
}

3. 发布Service端代码

a) 发布代码

protected Server() throws Exception {
// START SNIPPET: publish
System.out.println("Starting Server");
HelloServiceImpl implementor = new HelloServiceImpl ();
String address = "http://localhost:9000/helloWorld";
Endpoint.publish(address, implementor );
// END SNIPPET: publish
}

b) Main 函数

public static void main(String args[]) throws Exception {
new Server();
System.out.println("Server ready...");

Thread.sleep(5 * 60 * 1000);
System.out.println("Server exiting");
System.exit(0);
}

c) 运行Server端代码，并用浏览器打开“http://localhost:9000/helloWorld?wsdl”来验证WSDL是否生产。
4. 编写Client端代码

a) Client端代码：

public static void main(String[] args) {
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(HelloService.class);
factory.setAddress("http://localhost:9000/helloWorld");
HelloService client = (HelloService) factory.create();

String reply = client.sayHello("aaa");
System.out.println("Server said :".concat(reply));
System.exit(0);
}

b) 先启动服务器端代码，在启动Client端代码，可看到输出为“Hello aaa”.
