webservice -(四)-ksoap 2 对象作为参数

webservice -------(4)-----------ksoap 2 对象作为参数
注:代码质量不高，只是demo，请谅解

1、服务代码:
UserObjectService.java

package com.user.service;

import com.user.bean.User;

public class UserObjectService {

	public UserObjectService(){
		
	}
	/**
	 * 
	 * 比如用于用户登录
	 * 
	 * @param sql 客户端发到服务器的sql查询条件
	 * 
	 * @return 用户对象
	 */
	public User getUser(String sql){
		
		User user = new User();
		
		if(sql.equals("hello")){//不做与数据库之间的操作
			
			user.setUsername("hua");
			
			user.setPassword("123");
			
		}
	    return user;
	}
	
}

User.java

package com.user.bean;

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;

/**
 * 
 * 用户的JavaBean
 * 
 * @author Administrator
 *
 */
public class User {

	String username;//用户名
	
	String password;//密码
	
	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}
}

3、把上面的UserObjectService.java打包成服务


4、j2me进行测试的代码:

package com.user.client;

import java.io.IOException;

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

import org.ksoap2.*;
import org.ksoap2.serialization.*;
import org.ksoap2.transport.*;
import org.xmlpull.v1.XmlPullParserException;

public class TestUser2 extends MIDlet implements CommandListener {

	private Display dis;
	private Command connectCmd = new Command("连接", Command.OK, 1);
	private Command exitCmd = new Command("退出", Command.EXIT, 1);
	private Form f;
	private StringItem si = new StringItem("", "");

	public TestUser2() {
	}

	protected void destroyApp(boolean arg0) throws MIDletStateChangeException {

	}

	protected void pauseApp() {

	}

	protected void startApp() throws MIDletStateChangeException {
		dis = Display.getDisplay(this);
		f = new Form("调用Web Service");
		f.append("要显示的内容：" + "\n");
		f.addCommand(connectCmd);
		f.addCommand(exitCmd);
		f.setCommandListener(this);
		dis.setCurrent(f);
	}

	public void commandAction(Command c, Displayable s) {
		if (c == exitCmd)

		{
			try {

				destroyApp(false);

				notifyDestroyed();

			} catch (MIDletStateChangeException e) {
				e.printStackTrace();
			}
		}
		if (c == connectCmd) {
			//匿名内部Thread，调用ksoap2访问远程服务   
			Thread webserviceThread = new Thread() {
				public void run() {

					String serviceNamespace ="http://service.user.com";

					String methodName = "getUser";

					String serviceURL = "http://localhost:8090/WebServiceProject/services/UserObjectService";

					SoapObject request = new SoapObject(serviceNamespace,
							methodName);

					request.addProperty("sql", "hello");

					SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
							SoapEnvelope.VER11);

					envelope.bodyOut = request;

					HttpTransport ht = new HttpTransport(serviceURL);

					ht.debug = true;

					String Response = null;

					try {
						ht.call(null, envelope);//和.NET中SoapRpcMethod的Action一样   
					} catch (IOException e1) {
						// TODO Auto-generated catch block
						e1.printStackTrace();
					} catch (XmlPullParserException e1) {
						// TODO Auto-generated catch block
						e1.printStackTrace();
					}

					
					SoapObject ret = new SoapObject(serviceNamespace,
							"User");		

					try {
						ret =(SoapObject)envelope.getResponse();
					} catch (SoapFault e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					}
					
					
					System.out.println("*******"+ret.getProperty("username").toString());
					
					System.out.println("*******"+ret.getProperty("password").toString());
					
					System.out.println("dump>>" + ht.responseDump);

					si.setText(Response);

					f.append(si);

					f.removeCommand(connectCmd);

				}
			};

			webserviceThread.start();

		}

	}
}
