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度,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{

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;
}
