与Spring整合连接redis集群

1、接口封装

常用的操作redis的方法提取出一个接口，分别对应单机版和集群版创建两个实现类。

2、接口定义

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、单机版实现类

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();

4000
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、配置applicationContext-redis.xml

<?xml version="1.0" encoding="UTF-8"?>
<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"> 
<!-- 配置单机版的连接 -->
<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、集群版实现类

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、配置applicationContext-redis.xml

<!-- 集群版的配置 -->
<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"/>

集群版与单机版不能共存。

7、封装代码测试

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

}
