spring mvc配置redis缓存

在applicationContext.xml中配置：

<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">   <property name="maxIdle" value="300" />   <property name="maxActive" value="600" />   <property name="maxWait" value="1000" />   <property name="testOnBorrow" value="true" /></bean><bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"     p:host-name="127.0.0.1"     p:port="6379"     p:pool-config-ref="poolConfig"/><bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">   <property name="connectionFactory"   ref="connectionFactory" />   <property name="keySerializer">      <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>   </property>   <property name="valueSerializer">      <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"/>   </property></bean>

创建redisUtil：
