spring整合redis

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>
	
	<!-- Jedis ConnectionFactory -->
	<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>
	<!-- redis template definition -->
	<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>

代碼中的應用：

1.取數據：

String verifyResult = redisTemplate.opsForValue().get(
					SETTING_VERIFY + pub_openId + "_" + userident);//從redis當中獲取權限校驗結果
			Object querySettings = redisTemplate
					.opsForHash()
					.get("usersettings_",
							pub_openId + userident + UserSettingType.QUERY);//從reidis當中獲取用戶設置的有效期

2.存數據（先刪除數據、再存數據、最後設置數據保存週期）：

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