I do back in the game development companies, some data will be temporary to memcache
But when it came to developing such a question:
lot of background development in their own writing extension classes which use memcahce, will declare their own key.
Thus, for me to write my extended class, to use memcache, declared key , I was a bit tangled
I do not know which key has been used , I can not go to other people , I read through the code and see what key has been used. This is too cumbersome
Ever since, I do not know how to do ?
sum up the problem :
1 memcache the key how to manage it, is to put all the key are written in a separate statement inside a class , or write in a configuration file, so if you use a key which others can know . . Or are there better ways ? ? ? ?
For example, class A which has the code : memcache.set ("key1", value); memcache.set ("key2", value2); < br /> then class B which also has some of this code , memcache.set ("key3", value); memcache.set ("key4", value2);
also there are class C, class D , and so too much
so I set method when I do not know which key has been used by others .
2 memcache now there are a lot of data , and also can not be deleted , I want to know what key, how do you know ? ? I checked on the Internet , there is a way a lot of trouble : telnet connection memcache, stats items, then stats item index 0 this will put all the key listed, but it feels a lot of trouble , there is no other way to know what has been using key????

Recently read a book "Java TCP / IP Socket" The book explains some of the content on the Socket , which saw the content on obstruction after a little would not understand, you can not help me look at the code , why is there blocking ah ?
example , there are two cases, case 1 : will not clog ; case 2 : will be blocked ;
code is as follows :
//客户端 public class CompressClient { public static final int BUFSIZE = 256;
public static void main(String[] args) throws IOException { InetAddress inetAddr = InetAddress.getLocalHost(); int port = 8888; String fileName = "D:\\杂乱\\桌面.jpg";
FileOutputStream fileOut = new FileOutputStream(fileName + ".gz"); final FileInputStream fileIn = new FileInputStream(new File(fileName));
@Override public void run() { handleCompressClient(clntSock, logger); } }
Two commented the situation , but the use of a code , it will not be blocked . This is what principle ah ? We can explain the explanation? ------ Solution ---------------------------------------- ----
private static void sendBytes (Socket socket, InputStream fileIn) throws IOException { OutputStream sockOut = socket.getOutputStream (); int bytesRead = 0; byte [] buffer = new byte [BUFSIZE]; while ((bytesRead = fileIn.read (buffer))! = -1) / / Here will be blocked because if there is no bytes are read , then blocked { sockOut.write (buffer, 0, bytesRead); System.out.print ("W"); } System.out.println ("\ nClient send data complete!"); socket.shutdownOutput (); System.out.println ("Client is deadlock No?"); } The code in question , ------ Solution ------------------------------ --------------

Thank you, my own problems to solve , first you will good, but one thing you analyze wrong, when calling sockOut.write (buffer, 0, bytesRead), I found that the program is here was only blocked , indicating that - " receiving end SendQ queue has been filled , so will cause obstruction when the server calls sockOut.write (buffer, 0, bytesRead)", this problems with "Socket receive queue SendQ" about !
However, there still want to thank you , while ((bytesRead = in.read (buffer))! = -1) is used in this way depends on what the scene , You can also use the " custom message boundary character " to achieve .
Thank you ! ------ For reference only -------------------------------------- -
"! socket in the read (buffer) = -1 only established in one case ," you say this view is wrong , the correct view is : Only two views establishment , 1.socket.shutdownOutput () 2.socket.close (), I suggest you try it yourself ! ------ For reference only -------------------------------------- - I'm here to write the code , just learning to use , does not suggest that you direct use projects, is just learning to use Oh ! correct code is as follows :

byte[] temp = new byte[10]; int realLen = 0; while ((realLen = input.read(temp)) != -1) { System.out.println("【服务端】正在发送数据......"); output.write(temp, 0, realLen); } System.out.println("【客户端】发送数据完毕!"); output.flush();
client.close(); } }

Ask everyone calls between the two systems , it is the choice rpc or mq, talk about it and select your system
such rpc can be a simple spring httpinvoker, but the premise is all java applications and are used spring framework, can choose restful web service or a heavyweight soap web service, or use rmi, or write java api socket program ; mature soa or using third-party products, such as alibaba 's dubbo
or use mq system
