Simple Application of memcached in Java in the Widnows Environment

1. Preparations

1) memcached for Win32 server: http://code.jellycan.com/memcached/

The version used in this article: http://download.csdn.net/detail/supercrsky/5166196

2) memcached Java client: https://github.com/gwhalin/Memcached-Java-Client/downloads

The version used in this article: http://download.csdn.net/detail/supercrsky/5166537

2. Install the server

Put the downloaded memcached.exe file in the specified directory, for example, D: \ memcached. Open CMD and switch to D: \ memcached.

1) Installation

memcached.exe -d install

2) start the service

memcached.exe -d start

3) check whether the installation and startup are successful

Open the windows server and find the memcached Server service.

4) The detailed startup parameters are as follows:

-P listening port-l connection IP address, the default value is local-d start to start memcached service-D restart to restart memcached service-d stop | Shutdown to disable the running memcached service-D install to install memcached service-D uninstall to uninstall memcached service-u run as (only valid when running as root) -MB maximum memory usage, in MB. By default, an error is returned when 64mb-m memory is used up, instead of deleting the maximum number of concurrent connections in item-C. The default value is 1024-f, and the default value is 1.25-n, key + value + flags are 48-H display help by default

3. compile Java Test Cases

1. Place all the downloaded jar files in java_memcached-release_2.6.6.zip into the project lib and add the junit4 support.

2) Java code

Create the JavaBean to save <user>

Package com; import Java. io. serializable; import Java. util. date;/*** the serialization interface must be implemented <memcached requirements> * @ author zdw **/public class user implements serializable {Private Static final long serialversionuid = 1l; private long usid; private string username; private string password; private date createtime; public long getusid () {return usid;} public void setusid (long usid) {This. usid = usid;} 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;} public date getcreatetime () {return createtime;} public void setcreatetime (date createtime) {This. createtime = createtime ;}}

Test class:

Package com; import Java. util. date; import Org. JUnit. test; import COM. danga. memcached. memcachedclient; import COM. danga. memcached. sockiopool;/*** cache test * @ author zdw **/public class memcachedtest {private memcachedclient MC = new memcachedclient (); static {// specifies the server. The default value is local, the default port is 11211 string [] serverlist = {"127.0.0.1: 11211"}; sockiopool pool = sockiopool. getinstance (); pool. setservers (serverlist); pool. initialize () ;}@ testpublic void testadd () {user = new user (); User. setusername ("likaifu"); User. setpassword ("it"); User. setcreatetime (new date (); MC. set ("user1", user) ;}@ testpublic void testget () {user = (User) MC. get ("user1"); system. out. println (user. getUserName () ;}@ testpublic void testreplace () {user = new user (); User. setusername ("Li Kaifu"); User. setpassword ("kick"); User. setcreatetime (new date (); MC. replace ("user1", user );}}

First test the add method, then execute get; then execute replace, and then execute get method.

We found that the user instance has been saved to the memcached server.
