做自己的Socket网络通信框架【测试篇-simple】

项目在 http://susu.googlecode.com/svn/trunk/，项目里面的com.susu.test.nio下有两个测试程序simple和remotecmd。simple只是做了一个简单的测试，建立了一个简单服务器端，一个简单的客户端，当客户端连上服务器的时候，服务器给客户端发了一个报文，客户端建立了三个线程定时给服务器发报文，一段时间后客户端退出，下面来看代码实现，根据设计思想，我们必须完成下面的几个工作：

1. 定义一个报文接口，报文头长度为8位，十进制表示报文的长度，例如00000004test
2. 写一个TestIoHandler继承AbstractIoHandler类完成3个抽象方法
3. 写一个服务器端的输入过滤器，打印收到的报文，
4. 写一个服务器端的 输出过滤器，把要发送的报文加上8位的报文头，不足的补0
5. 写一个客户端的输入过滤器，打印收到的报文
6. 写一个客户端的 输出过滤器， 把要发送的报文加上8位的报文头，不足的补0
7. 写一个服务器端启动类，监听本地ip 9000端口
8. 写一个客户端的启动类，建立3个线程定时向服务器发报文

TestIoHandler的代码如下

package com.susu.test.nio.simple; import com.susu.common.CommException; import com.susu.common.nio.handler.AbstractIoHandler; /** * 报文定义，报文头为8为的字符串 */ public class TestIoHandler extends AbstractIoHandler { @Override protected int getLenth(byte[] lenth) { return Integer.parseInt(new String(lenth)); } protected int getLenthOfLenth() { return 8; } public void destroy() throws CommException { System.out.println("TestIoHandler:destroy"); } public void init() throws CommException { System.out.println("TestIoHandler:init"); } protected boolean hasContainHead() { return false; } }

服务器端的输入过滤器

package com.susu.test.nio.simple; import org.apache.log4j.Logger; import com.susu.common.CommException; import com.susu.common.nio.filter.InputFilter; import com.susu.common.nio.session.Session; /** * 当客户端连接上以后马上给客户端发送一个报文 */ public class ServerInputFilter implements InputFilter { private static Logger logger = Logger.getLogger(ServerInputFilter.class ); private int order; public ServerInputFilter(int order){ this.order=order; } public void destroy() throws CommException { System.out.println(this.toString()+"destroy"); } public int getOrder() { return order; } public void init() throws CommException { System.out.println(this.toString()+"init"); } public void onCloseSession(Session session) throws CommException { System.out.println(this.toString()+"onCloseSession"); } public void onCreateSession(Session session) throws CommException { System.out.println(this.toString()+"onCreateSession"); String s="user_type=1usewd=e10aba59abbe56e057f20f883ebran=B00000lan_ip=10.14.ain_flag=0user0078"; session.wirte(s); } public void onReceiveMessage(Session session) throws CommException { String s=new String((byte[])session.getReceiveMessage()); logger.info(this.toString()+"onReceiveMessage:"+s); } public String toString(){ return order+"-inputFilter:"; } }

服务器端的输出过滤器

package com.susu.test.nio.simple; import java.nio.ByteBuffer; import com.susu.common.CommException; import com.susu.common.nio.filter.OutputFilter; public class ServerOutputFilter implements OutputFilter { private int order; public ServerOutputFilter(int order){ this.order=order; } public void destroy() throws CommException { System.out.println(this.toString()+"destroy"); } public int getOrder() { return order; } public String toString(){ return order+"-outputFilter:"; } public void init() throws CommException { System.out.println(this.toString()+"init"); } public Object onSendMsg(Object msg) { int n=msg.toString().getBytes().length; int len=(""+n).length(); StringBuffer sb= new StringBuffer(1000); for(;len<8;len++){ sb.append("0"); } sb.append(n); sb.append(msg.toString()); byte [] src= sb.toString().getBytes(); ByteBuffer bb=ByteBuffer.allocate(src.length); bb.put(src,0,src.length); return bb; } }

客户端的输入过滤器

package com.susu.test.nio.simple; import org.apache.log4j.Logger; import com.susu.common.CommException; import com.susu.common.nio.filter.InputFilter; import com.susu.common.nio.session.Session; /** * 打印收到的报文数据 */ public class ClientInputFilter implements InputFilter { private static Logger logger = Logger.getLogger(ClientInputFilter.class ); private int order; public ClientInputFilter(int order){ this.order=order; } public void destroy() throws CommException { System.out.println(this.toString()+"destroy"); } public int getOrder() { return order; } public void init() throws CommException { System.out.println(this.toString()+"init"); } public void onCloseSession(Session session) throws CommException { System.out.println(this.toString()+"onCloseSession"); } public void onCreateSession(Session session) throws CommException { System.out.println(this.toString()+"onCreateSession"); } public void onReceiveMessage(Session session) throws CommException { String s=new String((byte[])session.getReceiveMessage()); logger.info(this.toString()+"onReceiveMessage:"+s); } public String toString(){ return order+"-inputFilter:"; } }

客户端输出过滤器

package com.susu.test.nio.simple; import java.nio.ByteBuffer; import com.susu.common.CommException; import com.susu.common.nio.filter.OutputFilter; /** * 把要发送的数据变为ByteBuffer 类型 */ public class ClinetOutputFilter implements OutputFilter { private int order; public ClinetOutputFilter(int order){ this.order=order; } public void destroy() throws CommException { System.out.println(this.toString()+"destroy"); } public int getOrder() { return order; } public String toString(){ return order+"-outputFilter:"; } public void init() throws CommException { System.out.println(this.toString()+"init"); } public Object onSendMsg(Object msg) { int n=msg.toString().getBytes().length; int len=(""+n).length(); StringBuffer sb= new StringBuffer(1000); for(;len<8;len++){ sb.append("0"); } sb.append(n); sb.append(msg.toString()); byte [] src= sb.toString().getBytes(); ByteBuffer bb=ByteBuffer.allocate(src.length); bb.put(src,0,src.length); return bb; } }

服务器启动类

package com.susu.test.nio.simple; import com.susu.common.nio.acceptor.NioSocketAcceptor; /** * 服务器端测试类，客户端一连接到服务器，就给客户端发送一个报文 * @author zhjb */ public class ServerTest { public static void main(String [] s){ try { NioSocketAcceptor acceptor= new NioSocketAcceptor(); TestIoHandler handler = new TestIoHandler(); acceptor.bind("127.0.0.1", 9000,handler); acceptor.addFilter(new ServerInputFilter(1)); acceptor.addFilter(new ServerOutputFilter(1)); acceptor.startupAcceptor(); } catch (Exception e) { e.printStackTrace(); } } }

客户端的启动类

package com.susu.test.nio.simple; import com.susu.common.nio.connector.NioSocketConnector; import com.susu.common.nio.session.Session; /** * 客户端测试类，连上服务器后定时给服务器发送报文 * @author zhjb */ public class ClientTest { boolean isRunning=true; NioSocketConnector connector ; TestIoHandler ioHandler; public static void main(String[] args) { ClientTest ct= new ClientTest(); ct.start(); } public void start(){ try { connector = new NioSocketConnector(); ioHandler=new TestIoHandler(); connector.addFilter(new ClientInputFilter(11)); connector.addFilter(new ClinetOutputFilter(11)); connector.init(); Client c= new Client(); c.setName("Test_Client1"); c.start(); c= new Client(); c.setName("Test_Client2"); c.start(); c= new Client(); c.setName("Test_Client3"); c.start(); Thread.sleep(1000*5); isRunning=false; Thread.sleep(1000*1); connector.close(); } catch (Exception e) { e.printStackTrace(); } } class Client extends Thread{ Session session; public void run(){ try { int n=0; session =connector.connect("127.0.0.1",9000,ioHandler); while(isRunning){ String s="MsgType=2CheckFlag0,TellerIDs=csl,acctNo=1000468931clientID=10004689sapplyDate=20081126apnt=1remainAmountremainAmount=1status=otraderID=gxb901000000523MsgType=2Chec00000RspMsg=操作成功amount=1applyDate=200rFlag=LNodeID=9010NodeType=6RootID=RspCode=RSP000ancelTime=clientID=1000468908instID=Au(T+D)localOrderNo=91391margin=0.00000000marginType= matchType=1memberID=9010offSetFlag=0orderNo=02000913price=201.00000000remainAmount=1status=otraderID=gxb901000000523MsgType=2CheckFlag=1AcctNos=1000468908BranchIDs=00000000,B00000,00009010,TellerIDs=csl,acctNo=1000468908ApiName=onRecvt=1applyDate=20081126applyTime=13:11:24buyOrSell=bcancelID=cancelTime=clientID=1000468908instID=Au(T+D)localOrdMsgType=2CheckFlag0,TellerIDs=csl,acctNo=1000468931clientID=10004689sapplyDate=20081126apnt=1remainAmountremainAmount=1status=otraderID=gxb901000000523MsgType=2Chec00000RspMsg=操作成功amount=1applyDate=200rFlag=LNodeID=9010NodeType=6RootID=RspCode=RSP000ancelTime=clientID=1000468908instID=Au(T+D)localOrderNo=91391margin=0.00000000marginType= matchType=1memberID=9010offSetFlag=0orderNo=02000913price=201.00000000remainAmount=1status=otraderID=gxb901000000523MsgType=2CheckFlag=1AcctNos=1000468908BranchIDs=00000000,B00000,00009010,TellerIDs=csl,acctNo=1000468908ApiName=onRecvt=1applyDate=20081126applyTime=13:11:24buyOrSell=bcancelID=cancelTime=clientID=1000468908instID=Au(T+D)localOrd"; session.wirte(s); n++; Thread.sleep(100); } System.out.println(this.getName()+":"+n); Thread.sleep(100); session.close(); } catch (Exception e) { e.printStackTrace(); } } } }

先启动ServerTest类，然后再启动ClientTest类，就是可以在控制台和日志里面看到日志信息。
