전통?적인 PropertyPlaceholderConfigurer 과 SpEL

전통적인? 방법과 SpEL을 사용해 properties파일 가져오는 방법

1. PropertyPlaceholderConfigurer 사용

	</bean>
	<bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
	<property name="connectionFactory" ref="connectionFactory" />
	</bean>
	<!-- Redis Source -->

2. SpEL 사용
아래 2개로 깔끔하게 처리
- <util:properties id="dataProps" location="classpath:properties/data.properties">
- #{dataProps['redis.host']}
