spring配置：

除了以上方式，在spring-data项目中增加了对redis的支持spring-data-redis，单独引入依赖：
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>1.4.2.RELEASE</version>
</dependency>使用spring-data-redis提供的RedisTemplate对redis操作，spring配置如下：
<?xml version='1.0' encoding='UTF-8'?>
<beans xmlns='http://www.springframework.org/schema/beans'
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
