Spring and redis integration integration steps

Spring and redis integration integration steps

1. Preparation

1. The redis service has been installed (windows version, linux version can be used)

2. Dependent jars: jedis-2.9.0.jar, commons-pool 2 -2.5.0.jar

2. Operation in java (stand-alone version -- jedis operation)

/**
	 * @description: Stand-alone version --jedis operation
	 * @param:
	 *
	 * @createDate: March 2, 2018 2:13:58 PM
	 */
	// @Test
	public void jedisSingle() throws Exception{
		//1. Create a jedis object
		Jedis jedis=new Jedis("192.168.1.194", 601, 20);
		jedis.auth("123");
		//2, get data
		String str = jedis.get("name");
		System.out.println(str);
		//3, close the resource
		jedis.close();
	}

3. Operation in java (stand-alone version--connection pool operation)

/**
	 * @description: Stand-alone version -- connection pool operation
	 * @param:
	 * @
	 * @createDate: March 2, 2018 at 2:14:47 PM
	 */
	@Test
	public void jedisPool() throws Exception{
		//1. Create a connection pool configuration object and set relevant properties
		JedisPoolConfig jedisPoolConfig=new JedisPoolConfig();
		jedisPoolConfig.setMaxIdle(300);
		jedisPoolConfig.setMaxTotal(10000);
		jedisPoolConfig.setMaxWaitMillis(200);
		//2、 创建连接池对象
		JedisPool jedisPool=new JedisPool(jedisPoolConfig,"192.168.1.194", 601,20,"123");
		//3、 从连接池中获取一个jedis对象
		Jedis jedis = jedisPool.getResource();
		//4、 获取数据
		String str = jedis.get("name");
		System.out.println(str);
		
		//5、 关闭资源 jedis 
		jedis.close();
		//6、 系统服务关闭时，释放连接池资源
		jedisPool.destroy();
	}

四、java中操作 （jedis 集群版操作）

/**
	 * @description: jedis 集群版操作
	 * @param:
	 * @
	 * @createDate:2018年3月2日 下午2:58:10
	 */
	@Test
	public void jedisCluster(){
		//1、 创建 jedisCluster 对象
		Set<redis.clients.jedis.HostAndPort> nodes=new HashSet<>();
		nodes.add(new redis.clients.jedis.HostAndPort("192.168.1.194",6011));
		nodes.add(new redis.clients.jedis.HostAndPort("192.168.1.194",6012));
		nodes.add(new redis.clients.jedis.HostAndPort("192.168.1.194",6013));
		nodes.add(new redis.clients.jedis.HostAndPort("192.168.1.194",6014));
		nodes.add(new redis.clients.jedis.HostAndPort("192.168.1.194",6015));
		nodes.add(new redis.clients.jedis.HostAndPort("192.168.1.194",6016));
		JedisCluster jedisCluster=new JedisCluster(nodes);
		
		//2、 获取数据
		String str = jedisCluster.get("name");
		System.out.println(str);

  //3、关闭资源
  jedisCluster.close();
	}

五、 jedis 和 spring 整合

1、 单机版-- 连接池

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
		<property name="maxIdle" value="300" /> <!-- 最大能够保持idel状态的对象数  -->
		<property name="maxTotal" value="60000" /> <!-- 最大分配的对象数 -->
		<property name="testOnBorrow" value="true" /> 
	</bean>

<bean id="jedisPool" class="redis.clients.jedis.JedisPool">
		<constructor-arg index="0" ref="jedisPoolConfig" />
		<constructor-arg index="1" value="${redis.host}" />
		<constructor-arg index="2" value="${redis.port}" type="int" />
		<constructor-arg index="3" value="${redis.timeout}" type="int"/>
		<constructor-arg index="4" value="${redis.password}"/>
	</bean>

2、集群版

<bean id="jedisCluster" class="redis.clients.jedis.JedisCluster"> 
		<constructor-arg>
			<set>
				<bean class="redis.clients.jedis.HostAndPort">
					<constructor-arg name="host" value="192.168.1.194"/>
					<constructor-arg name="port" value="6011"/>
				</bean>
				<bean class="redis.clients.jedis.HostAndPort">
					<constructor-arg name="host" value="192.168.1.194"/>
					<constructor-arg name="port" value="6012"/>
				</bean>
				<bean class="redis.clients.jedis.HostAndPort">
					<constructor-arg name="host" value="192.168.1.194"/>
					<constructor-arg name="port" value="6013"/>
				</bean>
				<bean class="redis.clients.jedis.HostAndPort">
					<constructor-arg name="host" value="192.168.1.194"/>
					<constructor-arg name="port" value="6014"/>
				</bean>
				<bean class="redis.clients.jedis.HostAndPort">
					<constructor-arg name="host" value="192.168.1.194"/>
					<constructor-arg name="port" value="6015"/>
				</bean>
				<bean class="redis.clients.jedis.HostAndPort">
					<constructor-arg name="host" value="192.168.1.194"/>
					<constructor-arg name="port" value="6016"/>
				</bean>			
			</set>
		</constructor-arg>
	</bean>
