Hello World for CshBBrain

 

CshBBrain开发示例

1.服务器定时推送广播消息

服务器每隔10秒钟将服务器的当前时间所对应的毫秒数发送给客户端,客户端接收服务器发送的消息并在网页上显示出来。

1.1 我们创建一个线程来每隔10秒发送一个消息:

 

protected void startBroadMessage(){// 定时发送广播消息的线程

while(true){

try{

Response rs = new Response();// 创建一个响应消息

String msg = "current datetime of server current datetime of server current datetime of server current datetime of server current datetime of server current datetime of server: " + System.currentTimeMillis();

//System.out.println(msg);

rs.setBody(msg);// 给响应消息设置内容

MasterServer.addBroadMessage(rs);// 将要发送的消息广播出去

broadMessageThread.sleep(10000);// 线程睡眠10秒钟

}catch(InterruptedException e){

e.printStackTrace();

}

}

}

 

1.2 启动服务器时,启动广播线程:

BroadThread.getInstance();// 创建广播线程

 

1.3 完整代码:

1.3.1 消息广播线程:

package com.jason.server.ws.biz;

 

import com.jason.server.Response;

import com.jason.server.MasterServer;

public class BroadThread {

private static BroadThread broadThread= new BroadThread();

private Thread broadMessageThread;// 发送广播消息的线程

public static BroadThread getInstance(){

return broadThread;

}

private BroadThread(){

// 消息广播线程

Runnable writeDistributeRunner = new Runnable(){

public void run(){

try{

startBroadMessage();

}catch(Exception e){

e.printStackTrace();

}

}

};

this.broadMessageThread = new Thread(writeDistributeRunner);

this.broadMessageThread.setName("广播消息生成线程");

this.broadMessageThread.start();

}

protected void startBroadMessage(){

while(true){

try{

Response rs = new Response();

String msg = "current datetime of server current datetime of server current datetime of server current datetime of server current datetime of server current datetime of server: " + System.currentTimeMillis();

//System.out.println(msg);

rs.setBody(msg);

MasterServer.addBroadMessage(rs);

broadMessageThread.sleep(10000);

}catch(InterruptedException e){

e.printStackTrace();

}

}

}

}

 

1.3.2 启动消息广播线程

package com.jason.server.ws;

 

import java.io.IOException;

 

import com.jason.server.MasterServer;

import com.jason.server.ws.biz.BroadThread;

public class Server{

 

/**

* <li>@param args

public static void main(String[] args){

try{

new MasterServer(new WebSocketCoder(), new WebSocketDecoder(), new Processer());

BroadThread.getInstance();

}catch(IOException e){

e.printStackTrace();

}

}

}

 

2.客户端与服务器相互发送消息

用户在网页上输入一个名字,提交到服务器,服务器回返回"Hello" + 提交的名字。

2.1 重写Service类中的 public Response service(Client sockector, HashMap<String, String> requestData)方法:

public Response service(Client sockector, HashMap<String, String> requestData){

if(requestData == null){

return null;

}

Response responseMessage = null;

try{

if(!MyStringUtil.isBlank(requestData.get(Constants.HANDSHAKE))){

responseMessage = Response.msgOnlyBody(requestData.get(Constants.FILED_MSG));

}else{

responseMessage = Response.msgOnlyBody("Hello," + requestData.get(Constants.FILED_MSG));// 将收到的人名前添加hello问候语

}

}catch(Exception e){

e.printStackTrace();

responseMessage = Response.msgOnlyBody("500处理失败了");

}

return responseMessage;

}
