Redis依賴的Jar

基於mavenhtml

<!-- redis client Dependency start-->
			<dependency>
				<groupId>redis.clients</groupId>
				<artifactId>jedis</artifactId>
				<version>2.9.0</version>
			</dependency>
			<dependency>
				<groupId>org.apache.commons</groupId>
				<artifactId>commons-pool2</artifactId>
				<version>2.4.2</version>
			</dependency>
<!-- redis client Dependency end -->

Redis客戶端直接鏈接

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import redis.clients.jedis.Jedis;

/**
 * Redis測試 .
 * @author longload
 * @date 2016年8月14日下午9:38:32
 */
public class RedisTest {
	private static final Logger LOGGER = LoggerFactory.getLogger(RedisTest.class);

	public static void main(String[] args) {
		
		Jedis jedis = new Jedis("192.168.48.110",6379,1000);
		String key = "test";
		String value = "";
		jedis.del(key); // 刪數據
		jedis.set(key, "test123"); // 存數據
		value = jedis.get(key); // 取數據
		LOGGER.info(key + "=" + value);
	}
}

而後能夠經過redis-cli 進行查看java

Spring整合

Xml配置文件(spring-redis.xml)

固然spring的加載文件須要引入該文件redis

<?xml version="1.0" encoding="UTF-8"?>
<beans
	xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"
	xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://www.springframework.org/schema/beans">

	<!-- Jedis連接池配置 -->
	<bean class="redis.clients.jedis.JedisPoolConfig" id="jedisPoolConfig">
		<property value="true" name="testWhileIdle" />
		<property value="60000" name="minEvictableIdleTimeMillis" />

	</bean>
	<bean class="redis.clients.jedis.ShardedJedisPool" id="shardedJedisPool">
		<constructor-arg ref="jedisPoolConfig" index="0" />
		<constructor-arg index="1">
			<list>
				<bean class="redis.clients.jedis.JedisShardInfo">
					<!-- redis服務器地址與端口 -->
					<constructor-arg value="192.168.48.110" index="0" />
					<constructor-arg value="6379" index="1" type="int" />
				</bean>
			</list>
		</constructor-arg>
	</bean>
</beans>

Spring使用的測試代碼

import javax.annotation.Resource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import redis.clients.jedis.ShardedJedis;
import redis.clients.jedis.ShardedJedisPool;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring/spring-context.xml")
public class RedisSpringTest {
	@Resource
	private ShardedJedisPool shardedJedisPool;
	
	Logger logger=LoggerFactory.getLogger(this.getClass());
	@Test
	 public void testOper(){
		ShardedJedis shardedJedis =shardedJedisPool.getResource();
		shardedJedis.set("test22", "11");
		logger.debug(shardedJedis.get("test22"));
		shardedJedis.del("test22");
		logger.debug(shardedJedis.get("test22"));
		shardedJedis.set("test22", "666");
		logger.debug(shardedJedis.get("test22"));
	}
}
