cxf快速发布webService之aegis

来源：互联网发布：iphone手机阅读软件编辑：程序博客网时间：2024/06/05 22:13

好一段时间都在做接口，以前有用axis2来做接口，后面在项目中有接触到cxf，看了相关的文档，个人就觉得，cxf做接口挺爽的，个人空闲时就开始了对cxf的学习。学习新的技术，新的语言，个人喜欢首先看demo，先把程序跑起来、看看效果，一般demo引入工程或多或少多会出点问题，可能是环境问题、少jar、版本不一致、与原有工程的东西冲突，等等。

cxf也有提供的样例，笔记中给出的样例比较简单易懂，记下笔记也是供后面用到这方面的技术，能快速使用上手。

开发环境：eclipse-jee-kepler-R-win32、jdk-7u3-windows-i586、内嵌web应用服务器jetty。

这是个maven项目，相关的项目定义、依赖由maven管理，样例结构预览：

cxf使用aegis绑定数据，自己主要关心服务代码的实现，aegis负责生成xml schema/wsdl xml，aegis测试项目主要提供了一个接口LuckyService，两个方法：获取城市天气、保存城市天气。

1、LuckyService代码清单

package com.toplucky.server;
/**

* @author CWL
* @version 1.0
* @see
* @since 1.0
* @Date 2014年8月13日上午10:53:20
*/
public interface LuckyService {
/**
* getCityWeather:获取城市天气
* @param cityCode 城市code
* @return
*/
Weather getCityWeather(String cityCode);
/**
* saveWeather:新增
* @param weather
* @return
*/
boolean saveWeather(Weather weather);
}

2、接口实现LuckyServiceImpl代码清单

/**
* LuckyServiceImpl.java
* com.toplucky.server
* Function：(一句话功能说明)
* version date author
* ──────────────────────────────────────

*/
package com.toplucky.server;
import java.util.Date;
import net.sf.json.JSONObject;
import org.apache.commons.httpclient.DefaultHttpMethodRetryHandler;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpStatus;
import org.apache.commons.httpclient.methods.GetMethod;

*/
public class LuckyServiceImpl implements LuckyService {
private static final Logger logger = LoggerFactory.getLogger(LuckyServiceImpl.class);
@Override
public Weather getCityWeather(String cityCode) {
Weather weather = new Weather();
String uri = "http://www.weather.com.cn/data/cityinfo/" + cityCode + ".html";
HttpClient httpClient = new HttpClient();
GetMethod getMethod = new GetMethod(uri);
getMethod.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
new DefaultHttpMethodRetryHandler());
try {
int statusCode = httpClient.executeMethod(getMethod);
if (statusCode != HttpStatus.SC_OK) {
logger.error("Method failed: " + getMethod.getStatusLine());
}
byte[] responseBody = getMethod.getResponseBody();
String responseStr = new String(responseBody);
JSONObject jsonObject = JSONObject.fromObject(responseStr);
Object temp = jsonObject.get("weatherinfo");
if (temp instanceof JSONObject){
JSONObject wtInfo = (JSONObject) temp;
//"temp1":"0℃","temp2":"10℃",
boolean temp1Lower = false;
String temp1 = wtInfo.get("temp1") + "";
String temp2 = wtInfo.get("temp2") + "";
StringBuilder wtBuilder = new StringBuilder();
wtBuilder.append(wtInfo.get("city")).append(" ")
.append(wtInfo.get("weather")).append(" ");
if (temp1.length() < temp2.length()) temp1Lower = true;
else if (temp1.length() == temp2.length()) {
if (temp1.compareTo(temp2) <= 0) temp1Lower = true;
}

if (temp1Lower) wtBuilder.append(temp1).append("～").append(temp2);
else wtBuilder.append(temp2).append("～").append(temp1);
weather.setDesc(wtBuilder.toString());
weather.setTime(DateUtil.formatDate(new Date(), "yyyy年MM月dd日 HH:mm"));
}
} catch (Exception e){
e.printStackTrace();
} finally {
getMethod.releaseConnection();
}
return weather;
}
@Override
public boolean saveWeather(Weather weather) {
logger.info("call saveWeather...");
logger.info("saveWeather.time=" + weather.getTime());
logger.info("saveWeather.weather=" + weather.getDesc());
return true;
}
}

3、气候Weather代码清单

/**
* Weather.java
* com.toplucky.server
* Function：(一句话功能说明)
* version date author
* ──────────────────────────────────────
* Ver 1.0 2014年8月13日 CWL
*
* Copyright(c) 2014, happyweekend All Rights Reserved.
*/
package com.toplucky.server;
/**
* (一句话功能说明)
* @author CWL
* @version 1.0
* @see
* @since 1.0
* @Date 2014年8月13日上午10:58:52
*/
public class Weather {
// 2013年12月25日 11:52
private String time;
// 成都阴 10 ℃～ 0 ℃
private String desc;
public String getTime() {
return time;
}
public void setTime(String time) {
this.time = time;
}
public String getDesc() {
return desc;
}
public void setDesc(String desc) {
this.desc = desc;
}
@Override
public String toString() {
return "Weather [time=" + time + ", desc=" + desc + "]";
}
}

这样一个获取天气的接口代码就算完成了，这里需要根据接口LuckyService配置aegis的一个文件LuckyService.aegis.xml，

相关配置会在生成的WSDL中体现

4、LuckyService.aegis.xml代码清单

<?xml version="1.0" encoding="UTF-8"?>
<mappings>
<mapping name="LuckyService">
<method name="getCityWeather">
<parameter index="0" mappedName="cityCode" nillable='false' />
</method>
<method name="saveWeather">
<parameter index="0" mappedName="weather" nillable='false' />
</method>
</mapping>
</mappings>

这样发布一个接口的准备工作已完成，接下来就是将接口发布出来供外部调用

5、发布接口类LuckyServer代码清单

/**

* com.toplucky.server

* ──────────────────────────────────────

*/
public class LuckyServer {
private static final Logger logger = LoggerFactory.getLogger(LuckyServer.class);
public static void main(String[] args) throws InterruptedException {
LuckyServiceImpl luckyServiceImpl = new LuckyServiceImpl();
ServerFactoryBean svrFactory = new ServerFactoryBean();
svrFactory.setServiceClass(LuckyService.class);

svrFactory.setServiceBean(luckyServiceImpl);
svrFactory.getServiceFactory().setDataBinding(new AegisDatabinding());
svrFactory.create();
logger.info("LuckyServer ready...");
}
}

6、客户端测试类LuckyClient代码清单

/**
* LuckyClient.java
* com.toplucky.client
*
* Function：(一句话功能说明)
* version date author
* ──────────────────────────────────────
* Ver 1.0 2014年8月13日 CWL

LuckyService client = factory.create(LuckyService.class);
logger.info("Invoke getCityWeather()....");
Weather weather = client.getCityWeather("101270101");
if (weather != null)
logger.info(weather.toString());
logger.info("Invoke saveWeather()....");
boolean success = client.saveWeather(weather);
logger.info(success + "");
}
}
