业务需求：通过手机号获取验证码，后台将验证码存放在redis数据库，供登录验证；
配置pom，加载依赖jar包：spring-data-redis、redis.clients两个依赖jar包
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.8.0</version>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>1.5.0.RELEASE</version>
</dependency>spring-redis.xml配置文件
<!-- 配置redis连接池 -->
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxIdle" value="100"/><!-- 最大闲置 -->
<property name="minIdle" value="10"/><!-- 最小闲置 -->
<property name="testOnBorrow" value="true"/><!-- 可以获取 -->
<!-- <property name="testOnReturn" value="true"/>-->
</bean>
<!-- redis 配置,也可以把配置挪到properties配置文件中,再读取 -->
<bean id="jedisPool" class="redis.clients.jedis.JedisPool">
<constructor-arg index="0" ref="jedisPoolConfig" />
<!-- 端口，默认6379 -->
<constructor-arg index="2" value="6379" name="port" type="int"/>
<constructor-arg index="3" value="5000" name="timeout" type="int"/>
<constructor-arg index="1" value="127.0.0.1" name="host" type="java.lang.String"/>
<!-- 如果你需要配置密码，请打开这里。
<constructor-arg index="4" value="你的密码" name="password" type="java.lang.String"/>
-->

}当用户提交验证码后，去redis数据库进行匹配就可以了！
