redis-java-api

 

redis 的 java 操作 api

至于 redis 五种数据类型, 和 redis 的命令操作, 和 client 端差不多的, 就不罗列了

代码 github 地址: https://github.com/wenbronk/redis-java.git

package com.iwhere.learn.redis.java;

import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Set;


import org.junit.Before;
import org.junit.Test;


import redis.clients.jedis.BinaryClient.LIST_POSITION;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.ShardedJedis;
