WebService处理.net中Dataset问题解决办法(转)

前段日子看到了一个提供WEB服务的网站-www.webxml.com.cn.它提供各种适用的Web服务。如天气预报、火车时刻表。

于是就通过它提供的接口，实验了一下，看看它提供的那些接口有什么效果。但是因为是免费用户，所以每次访问的次数有限制，所以只是测试一下。

但是你需要从WSDL文档中生成客户端支持代码，可以使用axis的wsdl2java：

%AXIS2_HOME%\bin\wsdl2java -uri?http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl?-p client -s -o stub

其中-url参数指定了wsdl文件的路径，可以是本地路径，也可以是网络路径。-p参数指定了生成的Java类的包名，-o参数指定了生成的一系列文件保存的根目录。

在执行完上面的命令后，读者就会发现在当前目录下多了个stub目录，在."stub"src"client目录可以找到一个SimpleServiceStub.java文件，该文件复杂调用WebService，

可以在程序中直接使用这个类。

我用了好几个服务,火车,天气,城市代码等。

先贴我的pojo,pojo需要和它提供的入口的属性一致，代码如下：

?Train.java

Java代码?

package?com.jushi.pojo;??
??
public?class?Train?{??
??
????private?String?trainStation;??
????private?String?arriveTime;??
????private?String?startTime;??
????private?String?km;??
??????
????private?String?firstStation;??
????private?String?lastStation;??
????private?String?trainCode;??
????private?String?startStation;??
????private?String?arriveStation;??
????private?String?useDate;??
??????
????public?String?getTrainStation()?{??
????????return?trainStation;??
????}??
????public?void?setTrainStation(String?trainStation)?{??
????????this.trainStation?=?trainStation;??
????}??
????public?String?getArriveTime()?{??
????????return?arriveTime;??
????}??
????public?void?setArriveTime(String?arriveTime)?{??
????????this.arriveTime?=?arriveTime;??
????}??
????public?String?getStartTime()?{??
????????return?startTime;??
????}??
????public?void?setStartTime(String?startTime)?{??
????????this.startTime?=?startTime;??
????}??
????public?String?getKm()?{??
????????return?km;??
????}??
????public?void?setKm(String?km)?{??
????????this.km?=?km;??
????}??
????public?String?getFirstStation()?{??
????????return?firstStation;??
????}??
????public?void?setFirstStation(String?firstStation)?{??
????????this.firstStation?=?firstStation;??
????}??
????public?String?getLastStation()?{??
????????return?lastStation;??
????}??
????public?void?setLastStation(String?lastStation)?{??
????????this.lastStation?=?lastStation;??
????}??
????public?String?getTrainCode()?{??
????????return?trainCode;??
????}??
????public?void?setTrainCode(String?trainCode)?{??
????????this.trainCode?=?trainCode;??
????}??
????public?String?getStartStation()?{??
????????return?startStation;??
????}??
????public?void?setStartStation(String?startStation)?{??
????????this.startStation?=?startStation;??
????}??
????public?String?getArriveStation()?{??
????????return?arriveStation;??
????}??
????public?void?setArriveStation(String?arriveStation)?{??
????????this.arriveStation?=?arriveStation;??
????}??
????public?String?getUseDate()?{??
????????return?useDate;??
????}??
????public?void?setUseDate(String?useDate)?{??
????????this.useDate?=?useDate;??
????}??
??????
}??

City.java

Java代码?

package?com.jushi.pojo;??
??
public?class?City?{??
??????
????private?String?cityId;??
????private?String?cityName;??
????public?String?getCityId()?{??
????????return?cityId;??
????}??
????public?void?setCityId(String?cityId)?{??
????????this.cityId?=?cityId;??
????}??
????public?String?getCityName()?{??
????????return?cityName;??
????}??
????public?void?setCityName(String?cityName)?{??
????????this.cityName?=?cityName;??
????}??
}??

接下来就是业务了。我们需要将它返回的数据集处理成我们需要的结果，所以用到了jdom。

?代码如下:

TrainInfo.java

Java代码?

package?com.jushi.service;??
??
import?java.io.File;??
import?java.io.FileInputStream;??
import?java.io.FileWriter;??

??
import?com.jushi.pojo.Train;??
??
public?class?TrainInfo?{??
??
????//通过车次得到列车信息???
????public?ArrayList?getInfo(String?traincode){??
????????ArrayList?trainlist?=?null;??
????????try{??
????????????java.net.URLEncoder.encode("参数","UTF-8");??
????????????TrainTimeWebServiceLocator?service?=?new?TrainTimeWebServiceLocator();??

????????????GetDetailInfoByTrainCodeResponseGetDetailInfoByTrainCodeResult?traininfo?=??
????????????????client.getDetailInfoByTrainCode(traincode,?"");//后面的是我新注册的userID:?eb01f699583d44d4bdee0ed47c0397d5??

????????????????return?null;??
????????????}??
????????????String?str?=?elementBody.get(0).toString();//消息体的字符串形式??
????????????saveXMLString(str,"train.xml");??
????????????trainlist?=?loadXML("train.xml");??
??????????????
