List数据存放至Redis，刷新缓存

1.初学习Redis,记录一下与List相关的一些操作

public void pushRedis(List<Store> stores){//刷新缓存
 StringBuffer buffer = new StringBuffer(); for(int i = 0; i < stores.size();i++){ Store store = stores.get(i); store.setIndexid(i); if(null == store.getId() || 0 == store.getId()){ storeDAO.insert(store); }else{ storeDAO.updateByPrimaryKey(store); } buffer.append(store.getItemid()).append(","); } redis.save("itemId", buffer.toString()); }

public List<Object> getItemList() {
    return redis.lRange("store-list", 0, -1);
}
public List<Store> update(List<Store> stores,int nowIndex,int reIndex){ Store store = stores.get(nowIndex); stores.remove(nowIndex); stores.add(reIndex - 1,store);
return stores; }//根据List中索引值改变元素位置

2. 备注：在applicationContext.xml进行相关的配置

<property name="locations">
    <list>
        <value>/WEB-INF/redis.properties</value>
        <value>/WEB-INF/jdbc.properties</value>
    </list>
</property>
<import resource="redis-config.xml" />

3.附带一个简单Redis测试类

public class Redis {

    public static void main(String[] args) {

        Jedis jedis = new Jedis("192.168.1.103",4352);

        //简单的key-value 存储
        jedis.set("tn", "thisuc");

        System.out.println(jedis.get("tn"));

        //在原有值的基础上添加，如若之前没有该key，则导入该key
        //之前已经设定了redis对应"myredis",此可执行便会使redis对应"myredisyourredis"
        jedis.append("redis","yourredis");
        jedis.append("content", "rabbit");

        System.out.println(jedis.get("redis"));

        //mset 是设置多个key value值 参数(key1,value1,key2,value2,key3,value3...)
        //mget 是获取多个key所对应的value值 参数（key1,key2,key3,...,keyn）
            jedis.mset("name1","thisuc","name2","gaoxc","name3","lemon");
        System.out.println(jedis.mget("name1","name2","name3"));
    }
}
