Java development: Share the use of memcached

In project development, some infrequently modified data, we usually choose to use the cache. One way is to memcached.

Windows system, we need to download and install memcached.

Address such as: D:\memcached\memcached.exe

Then, run Cmd.exe as administrator and enter the start command:

In this way, we can create a cache instance in the project:

 Public classMemcachedmanager {//creating Memcachedclient Global Objects    Private StaticMemcachedclient MCC =Newmemcachedclient (); Static {        //Create a server list and its weightsString[] Servers = {"127.0.0.1:11211" }; Integer[] Weights= {3 }; //Create a socket connection pool objectSockiopool pool =sockiopool.getinstance (); //setting up Server informationpool.setservers (servers);        Pool.setweights (weights); Pool.setfailover (true); //set the number of initial connections, minimum and maximum connections, and maximum processing timePool.setinitconn (5); Pool.setminconn (5); Pool.setmaxconn (250); Pool.setmaxidle (1000 * 60 * 60 * 6); //set the main thread sleep timePool.setmaintsleep (30); //setting TCP parameters, connection timeouts, and so onPool.setnagle (false); Pool.setsocketto (3000); Pool.setsocketconnectto (0); Pool.setalivecheck (true); //Initializing the connection poolpool.initialize (); }    /*** Non-parametric construction*/    protectedMemcachedmanager () {}//protected Objects    protected StaticMemcachedmanager instance =NewMemcachedmanager (); /*** Provides a public access method for protected objects*/     Public StaticMemcachedmanager getinstance () {returninstance; }    /*** Add object to cache, form method overload * *@paramKey *@paramValue *@return     */     Public BooleanAdd (String key, Object value) {returnMcc.add (key, value); }     Public BooleanAdd (String key, Object value, Date expiry) {returnMcc.add (key, value, expiry); }     Public BooleanReplace (String key, Object value) {returnmcc.replace (key, value); }     Public BooleanReplace (String key, Object value, Date expiry) {returnmcc.replace (key, value, expiry); }    /*** Gets the object according to the specified keyword*/     PublicObject get (String key) {returnMcc.get (key); }         Public Static voidMain (string[] args) {//Get Memcachedmanager InstancesMemcachedmanager cache =memcachedmanager.getinstance (); //Create test CacheCache.Add ("Test", "Hello"); //Remove Test CacheSystem.out.println (Cache.get ("Test")); //Modifying the test cacheCache.replace ("Test", "hello123"); //Remove Test CacheSystem.out.println (Cache.get ("Test")); }   }

After running this example, the printed results are as follows:

Hello
Hello123
