redis的propertis配置文件[spring][].propeties：

redis.url=127.0.0.1  
    redis.port=6379

applicationContext.xml中的配置：

<bean id="propertyConfigurer"
    		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    		<property name="locations">
    			<value>classpath:spring.properties</value>
    		</property>
    		<property name="systemPropertiesMode">
    			<value>1</value>
    		</property>
    		<property name="searchSystemEnvironment">
    			<value>true</value>
    		</property>
    		<property name="ignoreUnresolvablePlaceholders">
    			<value>true</value>
    		</property>
    	</bean>
    	
    	
    	<bean id="jedisConnectionFactory"
    		class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
    		p:host-name="${redis.url}" p:port="${redis.port}" >
    	</bean>
    	<bean id="stringRedisSerializer"
    		class="org.springframework.data.redis.serializer.StringRedisSerializer">
    	</bean>
    	
    	<bean id="redisTemplate" name="redisTemplate"
    		class="org.springframework.data.redis.core.RedisTemplate"
    		p:connection-factory-ref="jedisConnectionFactory" p:keySerializer-ref="stringRedisSerializer"
    		p:hashKeySerializer-ref="stringRedisSerializer">
    	</bean>

代码中的应用：

1.取数据：

String verifyResult = redisTemplate.opsForValue().get(
    		SETTING_VERIFY + pub_openId + "_" + userident);//从redis当中获取权限校验结果
    Object querySettings = redisTemplate.opsForHash().get("usersettings_",
    		pub_openId + userident + UserSettingType.QUERY);//从reidis当中获取用户设置的有效期

2.存数据（先删除数据、再存数据、最后设置数据保存周期）：

redisTemplate.delete(redisKey);
    redisTemplate.opsForValue().set(redisKey, condition);
    redisTemplate.expire(redisKey, 24 * 365, TimeUnit.HOURS);
