Spring Integrated Redis

1. environment

Need spring.jar, Common-pool.jar.jedisjar

2. Introduction

Sharding (shardedjedis) distributes different keys to different Redis servers for horizontal scaling Purposes.

3. Configure Application.xml

<!--loading Redis profiles--
<location="classpath:redis.properties"/> 

<!--connection Pool configuration--
<BeanID= "poolcfg"class= "redis.clients.jedis.JedisPoolConfig">        < propertyname= "maxtotal"value= "${redis.pool.maxactive}" />        < propertyname= "maxidle"value= "${redis.pool.maxidle}" />        < propertyname= "minidle"value= "1"/>        < propertyname= "maxwaitmillis"value= "${redis.pool.maxwait}" />        < propertyname= "testonborrow"value= "true"/>        < propertyname= "testonreturn"value= "true"/>    </Bean>
<!--port Remember to specify type int--<BeanID= "shardedjedispool"class= "redis.clients.jedis.ShardedJedisPool">        <Constructor-argIndex= "0"ref= "poolcfg"></Constructor-arg>        <Constructor-argIndex= "1">            <List>                <Beanname= "master"class= "redis.clients.jedis.JedisShardInfo">                    <Constructor-argIndex= "0"value= "${redis1.ip}"></Constructor-arg>                    <Constructor-argIndex= "1"value= "${redis1.port}"type= "int"></Constructor-arg>                    < propertyname= "password"value= "${redis2.auth}"/>                </Bean>                <Beanname= "slaver"class= "redis.clients.jedis.JedisShardInfo">                    <Constructor-argIndex= "0"value= "${redis2.ip}"></Constructor-arg>                    <Constructor-argIndex= "1"value= "${redis2.port}"type= "int"></Constructor-arg>                    < propertyname= "password"value= "${redis2.auth}"/>                </Bean>            </List>        </Constructor-arg></Bean>

4. Get resources, Release resources

@Repository ("jedisdataresource") public classJedisdataresourceimplImplementsJedisdataresource{@Resource (name= "shardedjedispool")    PrivateShardedjedispool sharededjedispool; @Override publicShardedjedis getresource () {shardedjedis Shardedjedis=NULL; Try{shardedjedis=Sharededjedispool.getresource (); returnshardedjedis; } Catch(Exception E) {if(NULL!=Sharededjedispool) Sharededjedispool.close (); }        return NULL; } @Override public voidReturnresource (shardedjedis Shardedjedis) {if(shardedjedis!=NULL) Shardedjedis.close (); }    }

5.dao Layer

 public Interface Userredisdao {        /** Get user name *    /double  getusername (String Key) ; }

@Repository ("userredisdao") public classUserredisdaoimplImplementsUserredisdao{@ResourcePrivateJedisdataresource jedisdataresource;@Override public Stringgetusername (String key) {shardedjedis Shardedjedis=Jedisdataresource.getresource (); if(NULL==Shardedjedis)returnNull; Try {            returnShardedjedis.get (key);        } Catch(Exception e) {e.printstacktrace ();        } finally{jedisdataresource.returnresource (shardedjedis); }    }
}

6.service

 public Interface commodityredisservice {        string getusername (string key);    }

@Service ("userredisservice")publicclassimplements  userredisservice{                @Autowired         Private Userredisdao userredisdao;        @Override        public  string increasecollectnum (string key) {            return userredisdao.getusername (key);}        }
