使用jedisCluster連接Redis集群(xml和代碼配置)

1.JedisCluster簡(jiǎn)介

? 一種優(yōu)雅的連接Redis集群的工具,配置連接池之后自動(dòng)獲取和釋放連接.

2.代碼配置方式

            JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
            jedisPoolConfig.setMaxTotal(100);
            jedisPoolConfig.setMaxIdle(30);
            jedisPoolConfig.setMaxWaitMillis(200);
            jedisPoolConfig.setTestOnBorrow(true);
            pool = new JedisPool(jedisPoolConfig, "IP", 7000, 2000, 10000, null, Protocol.DEFAULT_DATABASE, null);

            HostAndPort hostAndPort = new HostAndPort("IP", 7000);
            HostAndPort hostAndPort1 = new HostAndPort("IP", 7001);
            HostAndPort hostAndPort2 = new HostAndPort("IP", 7002);
            HostAndPort hostAndPort3 = new HostAndPort("IP", 7003);
            HostAndPort hostAndPort4 = new HostAndPort("IP", 7004);
            HostAndPort hostAndPort5 = new HostAndPort("IP", 7005);

            Set<HostAndPort> hostAndPortSet = new HashSet<>();
            hostAndPortSet.add(hostAndPort);
            hostAndPortSet.add(hostAndPort1);
            hostAndPortSet.add(hostAndPort2);
            hostAndPortSet.add(hostAndPort3);
            hostAndPortSet.add(hostAndPort4);
            hostAndPortSet.add(hostAndPort5);


            JedisCluster jedis = new JedisCluster(hostAndPortSet,jedisPoolConfig);
            jedis.set(k,v);
            jedis.get(k);

3.XML配置方式

? 配置完成后可以自動(dòng)注入,使用比較方便.

@Autowired
 private JedisCluster jedis;

3.1 加載配置文件

<!--加載數(shù)據(jù)庫(kù)文件，讀取數(shù)據(jù)庫(kù)相關(guān)信息,加載redis配置信息 -->
    <context:property-placeholder location="classpath:frontier-trade-business/redis.properties" />
    <import resource="classpath:frontier-trade-business/applicationContext-redis.xml" />

3.2 redis.properties

#JedisPoolConfig的參數(shù)
#最大連接數(shù)
redis.maxTotal=30
#最大空閑時(shí)間
redis.maxIdle=100
redis.maxWait=2000
redis.testOnBorrow=true
#主機(jī)和端口號(hào)
redis.host1=IP
redis.port1=7000
redis.host2=IP
redis.port2=7001
redis.host3=IP
redis.port3=7002
redis.host4=IP
redis.port4=7003
redis.host5=IP
redis.port5=7004
redis.host6=IP
redis.port6=7005
