SOAP之WebService、JSON传值问题

摘要: 张亚龙，于2012-8-17在OSchina发表，现在换账号，重新发表

首先，Server端（Java后台代码）：（web.xml、sun-jaxws.xml、BulletinService.java、BulletinServiceDelegate.java）

web.xml文件：

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
<servlet>
<description>JAX-WS endpoint - UsersServiceService</description>
<display-name>UsersServiceService</display-name>
<servlet-name>UsersServiceService</servlet-name>
<servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>UsersServiceService</servlet-name>
<url-pattern>/BulletinServicePort</url-pattern>
</servlet-mapping>

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<listener>
<listener-class>
com.sun.xml.ws.transport.http.servlet.WSServletContextListener
</listener-class>
</listener>
</web-app>

sun-jaxws.xml文件，和web.xml同目录下

<?xml version = "1.0"?>
<endpoints version="2.0" xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime">
<endpoint name="BulletinServicePort" implementation="com.sk.service.BulletinService"
url-pattern="/BulletinServicePort">
</endpoint>
</endpoints>

BulletinService.java文件service层，去调用dao层的方法

package com.sk.service;

import java.util.List;

import javax.jws.WebMethod;
import javax.jws.WebService;

import org.json.JSONArray;

import com.sk.dao.IBulletinDao;
import com.sk.dao.impl.BulletinDaoImpl;
import com.sk.vo.Gpw_Bulletin_Info;

@WebService
public class BulletinService {

IBulletinDao bulletinDao = new BulletinDaoImpl();

@WebMethod
public String find() {
List<Gpw_Bulletin_Info> list = bulletinDao.findAll();
// 调用查询方法
JSONArray jsonArray = new JSONArray(list);
return jsonArray.toString();
}

}

BulletinServiceDelegate.java文件service层，WebServices对外暴露数据

package com.sk.service;

@javax.jws.WebService(targetNamespace = "http://service.sk.com/", serviceName = "BulletinServiceService", portName = "BulletinServicePort")
public class BulletinServiceDelegate {

com.sk.service.BulletinService bulletinService = new com.sk.service.BulletinService();

public String find() {
return bulletinService.find();
}
}

然后，Client端（Android代码）：（Config.java、SOAPUtil.java、dbconfig.properties子三个文件完成Android客户端的WebServices部署）

Config.java文件

package com.sk.soap;

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

public class Config {
private static Properties prop = new Properties();
static{
try {
//加载配置文件dbonfig.properties
prop.load(Config.class.getResourceAsStream("dbconfig.properties"));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

//获取dbconfig.properties中的值
public static final String WSDL_HTTP = prop.getProperty("WSDL_HTTP");

}

SOAPUtil.java文件

package com.sk.soap;

import java.io.IOException;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import org.xmlpull.v1.XmlPullParserException;

import android.util.Log;

public class SOAPUtil {

public static Object TransportData(final String service, final String webMethod,Object[] params){
SoapObject request = new SoapObject("http://service.sk.com/", webMethod);
for(int i=0;i<params.length;i++){
Log.v("params", params[i].toString());
request.addProperty("arg"+i,params[i]);
}
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.bodyOut = request;
HttpTransportSE ht = new HttpTransportSE(Config.WSDL_HTTP+service);
try {
ht.call(null, envelope);
if (envelope.getResponse() != null) {
return envelope.getResponse();
}
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
}
return null;
}

}

dbconfig.properties文件，写链接地址

WSDL_HTTP=http\://192.168.0.91\:8080/SK_Java_Service/

最后看一下Activity中如何通过JOSN取后台传过来的值：

在oncreate()方法里边调用下边方法jsonAdapter()给适配器

List<Gpw_Bulletin_Info> list = this.jsonAdapter();
// 加载适配器
ListAdapter adapter = new ListAdapter(ListActivity.this, list);

list_LV.setAdapter(adapter);

private List<Gpw_Bulletin_Info> jsonAdapter() {
List<Gpw_Bulletin_Info> list = new ArrayList<Gpw_Bulletin_Info>();

Object obj = SOAPUtil.TransportData("BulletinServicePort?wsdl", "find",
new Object[] {});
String data = String.valueOf(obj.toString());
Log.i("TAG", "data=" + data);
if (data != null) {
try {
JSONArray json = new JSONArray(data);

for (int i = 0; i < json.length(); i++) {
Gpw_Bulletin_Info info = new Gpw_Bulletin_Info();

info.setBulletinid(((JSONObject) json.get(i))
.getInt("bulletinid"));
info.setTitle(((JSONObject) json.get(i)).getString("title"));
info.setHtmlcontent(((JSONObject) json.get(i))
.getString("htmlcontent"));
info.setStartdate(((JSONObject) json.get(i))
.getString("startdate"));

list.add(info);
}
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Toast.makeText(getApplicationContext(), "暂无数据！", Toast.LENGTH_SHORT)
.show();
}
return list;
}
