 <!--JedisPoolConfig 连接池参数配置-->
 <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
  <!--最大空闲实例数-->
  <property name="maxIdle" value="300" />
  <!--最大活跃实例数-->
  <property name="maxTotal" value="600" />
  <!--创建实例时最长等待时间-->
  <property name="maxWaitMillis" value="1000" />
  <!--创建实例时是否验证-->
  <property name="testOnBorrow" value="true" />
 </bean>

 <!--JedisConnectionFactory 跟配置数据库连接池类似,需要配置JedisConnectionFactory来通过服务器或者连接池的方式获取redis服务器的连接-->
 <bean id="connectionFactory"
   class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
  <property name="hostName" value="127.0.0.1"/>
  <property name="port" value="6379"/>
  <property name="usePool" value="true"/>
  <property name="poolConfig" ref="poolConfig"/>
 </bean>

 <bean id="valueSerializer" class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"/>


 <!-- redis模板配置 spring-data-redis提供了一个基础的泛型RedisTemplate封装了基础的crud操作-->
 <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
  <property name="connectionFactory" ref="connectionFactory"/>
  <property name="defaultSerializer" ref="stringRedisSerializer"/>
  <property name="keySerializer" ref="stringRedisSerializer"/>
  <property name="valueSerializer" ref="valueSerializer"/>
