Java local cache and Redis cache

Local cache

The local cache is stored in memory and the cache is implemented as follows

First you need to introduce a package

<dependency>    <groupId>net.sf.ehcache</groupId>    <artifactid>ehcache</ Artifactid>    <version>2.10.1</version></dependency>

Cache Service Interface:

Package Com.mobcb.platform.service.common;import Net.sf.ehcache.cache;public Interface Ehcacheservice {public    void ClearCache (String cachename, String cacheKey);    public void Putcache (string cachename, String CacheKey, Object value);    Public Object Getcachevalue (string cachename, String cacheKey);    Public Cache GetCache (String cachename);    /**     * Set Cache     *     * @param cachename         cache name     * @param cacheKey          cache Key     * @param value             value     * @param timetoliveseconds existence time, per second     *    /public void Putcache (string cachename, String CacheKey, Object Value,            int timetoliveseconds);}

Ehcacheservice Interface Implementation:

Package Com.mobcb.platform.service.impl.common;import Com.mobcb.platform.service.common.ehcacheservice;import Javax.annotation.resource;import Net.sf.ehcache.cache;import Net.sf.ehcache.cachemanager;import Net.sf.ehcache.element;import Org.apache.commons.logging.log;import Org.apache.commons.logging.logfactory;import Org.springframework.stereotype.Service, @Service ("Ehcacheservice") public class Ehcacheserviceimpl implements    Ehcacheservice {private static Log logger = Logfactory.getlog (Ehcacheserviceimpl.class);    @Resource (name = "Ehcachemanager") private CacheManager Cachemanger;    Private Boolean createcacheifnotfound = true;        @Override public void ClearCache (string cachename, String cacheKey) {Cache cache = GetCache (cachename);        if (cache = = null) {return;    } cache.remove (CacheKey); } @Override public void Putcache (string cachename, String CacheKey, Object value) {Cache cache = GetCache (ca        Chename); if (cache = = null) {return;    } cache.put (New Element (CacheKey, value)); } @Override Public Object getcachevalue (string cachename, String cacheKey) {Cache cache = GetCache (cachename        );        if (cache = = null) {return null;        } element element = Cache.get (CacheKey);        if (element = = NULL | | element.isexpired ()) {return null;    } return Element.getobjectvalue ();        } @Override Public Cache getcache (String cachename) {Cache cache = Cachemanger.getcache (cachename);        if (cache = = NULL && createcacheifnotfound) {cache = (cache) cachemanger.addcacheifabsent (cachename);                    } if (cache = = null) {Logger.error ("Ehcache:cache not config and not auto created, cachename="        + CacheName);    } return cache;     } @Override public void Putcache (string cachename, String CacheKey, Object value, int timetoliveseconds) {   Cache cache = GetCache (cachename);        if (cache = = null) {return;    } cache.put (New Element (CacheKey, Value, Timetoliveseconds, timetoliveseconds)); }}

Examples of cache usage:

Introducing the Cache service interface

/** * Cache Service */@Resource (name = "Ehcacheservice") private Ehcacheservice Ehcacheservice;

Call:

Object Requestsource = Ehcacheservice.getcachevalue (        "Shcauth", "Shcauthkey"); Logger.info ("------------------- -----Cache to obtain the authentication code "+requestsource+"-----------------------");

The first parameter is the cache name, and the second is the key value under the cache name.
