手机验证码如何储存在redis数据库中(spring 集成redis)

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.clientsgroupId>
                <artifactId>jedisartifactId>
                <version>2.8.0version>
            dependency>
            <dependency>
        <groupId>org.springframework.datagroupId>
        <artifactId>spring-data-redisartifactId>
        <version>1.5.0.RELEASEversion>
    dependency>

spring-redis.xml配置文件

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxIdle" value="100"/>
        <property name="minIdle" value="10"/>
        <property name="testOnBorrow" value="true"/>

    bean>
    
    <bean id="jedisPool" class="redis.clients.jedis.JedisPool">
        <constructor-arg index="0" ref="jedisPoolConfig" />
        
        <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"/>

当用户提交验证码后，去redis数据库进行匹配就可以了！
