用redis存取三级联动省市县

我搜索了一下，发现用redis存取三级联动的内容很少，所以就自己写了一份。

这里使用单机版的redis进行数据的存取的，后台用了springmvc，前台用的bootstrap，代码准备的比较全，所以有点多，望众知：

配置文件 applicationContext-redis.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <!--将redis对象交给spring容器管理-->
    <!--注册单机版的redis，创建jedisPool，需要通过构造方法注入port和host-->
    <!--连接redis的单机版-->
    <!--注册单机版的实现类-->
    <bean id="jedisClientPool" class="com.buba.witkey.redis.impl.JedisClientPool">
        <property name="jedisPool" ref="jedisPool"/>

    </bean>
    <bean id="jedisPool" class="redis.clients.jedis.JedisPool">
        <constructor-arg name="host" value="192.168.43.185" />
        <constructor-arg name="port" value="7111"/>
    </bean>
    <!--单机和集群只能有一个存在-->
    
</beans>

创建如下目录结构：

JedisClient：

package com.buba.witkey.redis;

public interface JedisClient {

    String set(String key, String value);
    String get(String key);
    Boolean exists(String key);
    Long expire(String key, int seconds);
    Long ttl(String key);
    Long incr(String key);
    Long hset(String key, String field, String value);
    String hget(String key, String field);
    Long hdel(String key, String... field);
}

JedisClientCluster：

package com.buba.witkey.redis.impl;

import com.buba.witkey.redis.JedisClient;
import redis.clients.jedis.JedisCluster;
import javax.annotation.Resource;
public class JedisClientCluster implements JedisClient {
    @Resource
    private JedisCluster jedisCluster;
    public JedisCluster getJedisCluster() {
        return jedisCluster;
    }
    public void setJedisCluster(JedisCluster jedisCluster) {
        this.jedisCluster = jedisCluster;
    }
    @Override
    public String set(String key, String value) {
        return jedisCluster.set(key, value);
    }
    @Override
    public String get(String key) {
        return jedisCluster.get(key);
    }
    @Override
    public Boolean exists(String key) {
        return jedisCluster.exists(key);
    }
    @Override
    public Long expire(String key, int seconds) {
        return jedisCluster.expire(key, seconds);
    }
    @Override
    public Long ttl(String key) {
        return jedisCluster.ttl(key);
    }
    @Override
    public Long incr(String key) {
        return jedisCluster.incr(key);
    }
    @Override
    public Long hset(String key, String field, String value) {
        return jedisCluster.hset(key, field, value);
    }
    @Override
    public String hget(String key, String field) {
        return jedisCluster.hget(key, field);
    }
    @Override
    public Long hdel(String key, String... field) {
        return jedisCluster.hdel(key, field);
    }
}

JedisClientPool：

package com.buba.witkey.redis.impl;
import com.buba.witkey.redis.JedisClient;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import javax.annotation.Resource;
public class JedisClientPool implements JedisClient {
    @Resource
    private JedisPool jedisPool;
    public JedisPool getJedisPool() {
        return jedisPool;
    }
    public void setJedisPool(JedisPool jedisPool) {
        this.jedisPool = jedisPool;
    }
    @Override
    public String set(String key, String value) {
        Jedis jedis = jedisPool.getResource();
        String result = jedis.set(key,value);
        jedis.close();
        return result;
    }
    @Override
    public String get(String key) {
        return null;
    }
    @Override
    public Boolean exists(String key) {
        return null;
    }
    @Override
    public Long expire(String key, int seconds) {
        return null;
    }
    @Override
    public Long ttl(String key) {
        return null;
    }
    @Override
    public Long incr(String key) {
        return null;
    }
    @Override
    public Long hset(String key, String field, String value) {
        Jedis jedis = jedisPool.getResource();
        Long result = jedis.hset(key,field,value);
        jedis.close();
        return result;
    }
    @Override
    public String hget(String key, String field) {
        Jedis jedis = jedisPool.getResource();
        String result = jedis.hget(key,field);
        jedis.close();
        return result;
    }
    @Override
    public Long hdel(String key, String... field) {
        return null;
    }
}

后台代码实现：

        return list2;
    }

    @Override
