Springとの接続redisクラスタの統合

1、インタフェースパッケージでよく使われる操作redisの方法は1つのインタフェースを抽出し、それぞれ単機版とクラスタ版に対応して2つの実装クラスを作成する.2、インタフェース定義

public interface JedisClient {

    String set(String key, String value);
    String get(String key);
    Boolean exists(String key);
    Long expire(String key, int seconds);
    Long ttl(String key);
    Long incr(String key);
    Long hset(String key, String field, String value);
    String hget(String key, String field);
    Long hdel(String key, String... field);
}

3、単機版実現類

public class JedisClientPool implements JedisClient {

    @Autowired
    private JedisPool jedisPool;

    @Override
    public String set(String key, String value) {
        Jedis jedis = jedisPool.getResource();
        String result = jedis.set(key, value);
        jedis.close();
        return result;
    }

    @Override
    public String get(String key) {
        Jedis jedis = jedisPool.getResource();
        String result = jedis.get(key);
        jedis.close();
        return result;
    }

    @Override
    public Boolean exists(String key) {
        Jedis jedis = jedisPool.getResource();
        Boolean result = jedis.exists(key);
        jedis.close();
        return result;
    }

    @Override
    public Long expire(String key, int seconds) {
        Jedis jedis = jedisPool.getResource();
        Long result = jedis.expire(key, seconds);
        jedis.close();
        return result;
    }

    @Override
    public Long ttl(String key) {
        Jedis jedis = jedisPool.getResource();
        Long result = jedis.ttl(key);
        jedis.close();
        return result;
    }

    @Override
    public Long incr(String key) {
        Jedis jedis = jedisPool.getResource();
        Long result = jedis.incr(key);
        jedis.close();
        return result;
    }

    @Override
    public Long hset(String key, String field, String value) {
        Jedis jedis = jedisPool.getResource();
        Long result = jedis.hset(key, field, value);
        jedis.close();
        return result;
    }

    @Override
    public String hget(String key, String field) {
        Jedis jedis = jedisPool.getResource();
        String result = jedis.hget(key, field);
        jedis.close();
        return result;
    }

    @Override
    public Long hdel(String key, String... field) {
        Jedis jedis = jedisPool.getResource();
        Long result = jedis.hdel(key, field);
        jedis.close();
        return result;
    }

}

4、アプリケーションContext-redisを構成する.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans4.2.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context4.2.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx4.2.xsd
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util4.2.xsd">

    
    <bean id="jedisPool" class="redis.clients.jedis.JedisPool">
        <constructor-arg name="host" value="192.168.25.153">constructor-arg>
        <constructor-arg name="port" value="6379">constructor-arg>
    bean>
    <bean id="jedisClientPool" class="com.taotao.jedis.JedisClientPool"/>

beans>

5、クラスタ版実現クラス

package com.taotao.jedis;

import org.springframework.beans.factory.annotation.Autowired;

import redis.clients.jedis.JedisCluster;

public class JedisClientCluster implements JedisClient {

    @Autowired
    private JedisCluster jedisCluster;

    @Override
    public String set(String key, String value) {
        return jedisCluster.set(key, value);
    }

    @Override
    public String get(String key) {
        return jedisCluster.get(key);
    }

    @Override
    public Boolean exists(String key) {
        return jedisCluster.exists(key);
    }

    @Override
    public Long expire(String key, int seconds) {
        return jedisCluster.expire(key, seconds);
    }

    @Override
    public Long ttl(String key) {
        return jedisCluster.ttl(key);
    }

    @Override
    public Long incr(String key) {
        return jedisCluster.incr(key);
    }

    @Override
    public Long hset(String key, String field, String value) {
        return jedisCluster.hset(key, field, value);
    }

    @Override
    public String hget(String key, String field) {
        return jedisCluster.hget(key, field);
    }

    @Override
    public Long hdel(String key, String... field) {
        return jedisCluster.hdel(key, field);
    }

}

6、アプリケーションContext-redisを構成する.xml

    <bean id="jedisCluster" class="redis.clients.jedis.JedisCluster">
        <constructor-arg>
            <set>
                <bean class="redis.clients.jedis.HostAndPort">
                    <constructor-arg name="host" value="192.168.25.153">constructor-arg>
                    <constructor-arg name="port" value="7001">constructor-arg>
                bean>
                <bean class="redis.clients.jedis.HostAndPort">
                    <constructor-arg name="host" value="192.168.25.153">constructor-arg>
                    <constructor-arg name="port" value="7002">constructor-arg>
                bean>
                <bean class="redis.clients.jedis.HostAndPort">
                    <constructor-arg name="host" value="192.168.25.153">constructor-arg>
                    <constructor-arg name="port" value="7003">constructor-arg>
                bean>
                <bean class="redis.clients.jedis.HostAndPort">
                    <constructor-arg name="host" value="192.168.25.153">constructor-arg>
                    <constructor-arg name="port" value="7004">constructor-arg>
                bean>
                <bean class="redis.clients.jedis.HostAndPort">
                    <constructor-arg name="host" value="192.168.25.153">constructor-arg>
                    <constructor-arg name="port" value="7005">constructor-arg>
                bean>
                <bean class="redis.clients.jedis.HostAndPort">
                    <constructor-arg name="host" value="192.168.25.153">constructor-arg>
                    <constructor-arg name="port" value="7006">constructor-arg>
                bean>
            set>
        constructor-arg>
    bean>
    <bean id="jedisClientCluster" class="com.taotao.jedis.JedisClientCluster"/>

クラスタ版とスタンドアロン版は共存できません.
7、パッケージコードテスト

@Test
    public void testJedisClient() throws Exception {
        //   Spring  
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-*.xml");
        //      JedisClient  
        JedisClient jedisClient = applicationContext.getBean(JedisClient.class);
        jedisClient.set("first", "100");
        String result = jedisClient.get("first");
        System.out.println(result);


    }
