Java6 WebService客户端封装
在开发WebService客户端应用的时候，面临的最大挑战是事先不知道服务端要部署在哪里，端口是什么，因此Hello World的例子并不适合生产环境，还需要进一步的做改进。?改进的总体思想是将静态的部分替换为动态的，也就是说，将服务的ip和端口，做成动态参数，然后根据服务端的部署灵活改变这些配置参数。?下面针对前面的例子对客户端做一个改进。?1、写WebService服务的配置参数文件?wscfg.properties#Java6WS服务的配置
Java6WS.wsip=192.168.14.117
Java6WS.wsport=8888?2、写配置参数获取工具?SysParamsToolkit.javapackage lavasoft.common;

import java.io.IOException;
import java.util.Properties;

/**
* 媒资系统配置文件参数获取工具

public final class SysParamsToolkit {
????????private static Properties prop;

????????private SysParamsToolkit() {
????????}

????????static {
????????????????reload();
????????}

????????public static boolean reload() {
????????????????boolean flag = true;
????????????????prop = new Properties();
????????????????try {
????????????????????????prop.load(SysParamsToolkit.class.getResourceAsStream("/wscfg.properties"));
????????????????????????flag = false;
????????????????} catch (IOException e) {
????????????????????????e.printStackTrace();
????????????????}
????????????????return flag;
????????}

????????public static Properties getSysProperties() {
????????????????return prop;
????????}

????????/**
???????? * 获取指定的系统属性值
???????? *
???????? * @param key 指定的属性名称
???????? * @return 指定的系统属性值
???????? */
????????public static String getProperty(String key) {
????????????????return prop.getProperty(key);
????????}

????????/**
???????? * 获取指定的系统属性值
???????? *
???????? * @param key????????????????指定的属性名称
???????? * @param defaultVal 默认值
???????? * @return 指定的系统属性值
???????? */
????????public static String getProperty(String key, String defaultVal) {
????????????????return prop.getProperty(key, defaultVal);
????????}

????????public static void main(String[] args) {
????????????????Properties prop = getSysProperties();
????????}
}?3、修改Java6工具生成的代码，改静态的IP和端口为动态的参数。?这一步是最关键的一步，前面的都是准备工作，这一步才是实质性的工作，首先你要找到所生成客户端代码的服务接口实现类，在此是Java6WSService类。@WebServiceClient(name = "Java6WSService", targetNamespace = "http://server.lavasoft/", wsdlLocation = "http://192.168.14.117:8080/java6ws/Java6WS?wsdl")
public class Java6WSService
????????????????extends Service {
????????private final static URL JAVA6WSSERVICE_WSDL_LOCATION;
????????private final static Logger logger = Logger.getLogger(lavasoft.wsclient.Java6WSService.class.getName());

????????static {
????????????????String wsip = SysParamsToolkit.getProperty("wsip", "192.168.14.117");
????????????????String wsport = SysParamsToolkit.getProperty("wsport", "8888");
????????????????URL url = null;
????????????????try {
????????????????????????URL baseUrl;
????????????????????????baseUrl = lavasoft.wsclient.Java6WSService.class.getResource(".");
????????????????????????url = new URL(baseUrl, "http://" + wsip + ":" + wsport + "/java6ws/Java6WS?wsdl");
????????????????} catch (MalformedURLException e) {
????????????????????????logger.warning("Failed to create URL for the wsdl Location: '"+"http://" + wsip + ":" + wsport + "/java6ws/Java6WS?wsdl"+"', retrying as a local file");
????????????????????????logger.warning(e.getMessage());
????????????????}
????????????????JAVA6WSSERVICE_WSDL_LOCATION = url;
????????}

......?到此，大功告成了，你的客户端代码具有了可配置功能了。可以不再担心服务端如何部署了。?运行一把看看： Java6 WebService客户端打包 ?由于客户端生成的代码超多，不能一一贴出，也没必要，详细源码请查看附件。
