Jedis是Redis的Java客户端，Spring将Jedis连接池作为一个Bean来配置。如果在Spring Data的官网上可以发现，Spring Data Redis已经将Jedis集成进去了。
Jedis连接池分为两种：
一种是“redis.clients.jedis.ShardedJedisPool”，这是基于hash算法的一种分布式集群Redis客户端连接池。
另一种是“redis.clients.jedis.JedisPool”，这是单机环境适用的Redis连接池。
下面是介绍详细的集成方式：
POM：
<!-- Redis依赖包 --> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.9.0</version> </dependency>
ShardedJedisPool是Redis集群客户端的对象池，可以通过他来操作ShardedJedis，下面是ShardedJedisPool的XML配置，spring-jedis.xml：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 引入jedis的properties配置文件 --> <!--如果你有多个数据源需要通过<context:property-placeholder管理，且不愿意放在一个配置文件里，那么一定要加上ignore-unresolvable=“true"--> <context:property-placeholder location="classpath:properties/redis.properties" ignore-unresolvable="true" /> <!--shardedJedisPool的相关配置--> <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <!--新版是maxTotal，旧版是maxActive--> <property name="maxTotal"> <value>${redis.pool.maxActive}</value> </property> <property name="maxIdle"> <value>${redis.pool.maxIdle}</value> </property> <property name="testOnBorrow" value="true"/> <property name="testOnReturn" value="true"/> </bean> <bean id="shardedJedisPool" class="redis.clients.jedis.ShardedJedisPool" scope="singleton"> <constructor-arg index="0" ref="jedisPoolConfig" /> <constructor-arg index="1"> <list> <bean class="redis.clients.jedis.JedisShardInfo"> <constructor-arg name="host" value="${redis.uri}" /> </bean> </list> </constructor-arg> </bean> </beans>
下面是单机环境下Redis连接池的配置：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 引入jedis的properties配置文件 --> <!--如果你有多个数据源需要通过<context:property-placeholder管理，且不愿意放在一个配置文件里，那么一定要加上ignore-unresolvable=“true"--> <context:property-placeholder location="classpath:properties/redis.properties" ignore-unresolvable="true" /> <!--Jedis连接池的相关配置--> <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <!--新版是maxTotal，旧版是maxActive--> <property name="maxTotal"> <value>${redis.pool.maxActive}</value> </property> <property name="maxIdle"> <value>${redis.pool.maxIdle}</value> </property> <property name="testOnBorrow" value="true"/> <property name="testOnReturn" value="true"/> </bean> <bean id="jedisPool" class="redis.clients.jedis.JedisPool"> <constructor-arg name="poolConfig" ref="jedisPoolConfig" /> <constructor-arg name="host" value="${redis.host}" /> <constructor-arg name="port" value="${redis.port}" type="int" /> <constructor-arg name="timeout" value="${redis.timeout}" type="int" /> <constructor-arg name="password" value="${redis.password}" /> <constructor-arg name="database" value="${redis.database}" type="int" /> </bean> </beans>
对应的classpath:properties/redis.properties为：
#最大分配的对象数
redis.pool.maxActive=200
#最大能够保持idel状态的对象数
redis.pool.maxIdle=50
redis.pool.minIdle=10
redis.pool.maxWaitMillis=20000
#当池内没有返回对象时，最大等待时间
redis.pool.maxWait=300
#格式：redis://:[密码]@[服务器地址]:[端口]/[db index]
redis.uri = redis://:12345@127.0.0.1:6379/0
redis.host = 127.0.0.1
redis.port = 6379
redis.timeout=30000
redis.password = 12345
redis.database = 0
二者操作代码类似，都是先注入连接池，然后通过连接池获得Jedis实例，通过实例对象操作Redis。
ShardedJedis操作：
@Autowired private ShardedJedisPool shardedJedisPool;//注入ShardedJedisPool @RequestMapping(value = "/demo_set",method = RequestMethod.GET) @ResponseBody public String demo_set(){ //获取ShardedJedis对象 ShardedJedis shardJedis = shardedJedisPool.getResource(); //存入键值对 shardJedis.set("key1","hello jedis"); //回收ShardedJedis实例 shardJedis.close(); return "set"; } @RequestMapping(value = "/demo_get",method = RequestMethod.GET) @ResponseBody public String demo_get(){ ShardedJedis shardedJedis = shardedJedisPool.getResource(); //根据键值获得数据 String result = shardedJedis.get("key1"); shardedJedis.close(); return result; }
Jedis操作：
@Autowired private JedisPool jedisPool;//注入JedisPool @RequestMapping(value = "/demo_set",method = RequestMethod.GET) @ResponseBody public String demo_set(){ //获取ShardedJedis对象 Jedis jedis = jedisPool.getResource(); //存入键值对 jedis.set("key2","hello jedis one"); //回收ShardedJedis实例 jedis.close(); return "set"; } @RequestMapping(value = "/demo_get",method = RequestMethod.GET) @ResponseBody public String demo_get(){ Jedis jedis = jedisPool.getResource(); //根据键值获得数据 String result = jedis.get("key2"); jedis.close(); return result; }
