我是靠谱客的博主正直服饰，最近开发中收集的这篇文章主要介绍java操作redis数据类型的demo，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1.pom.xml

<dependency>
           <groupId>redis.clients</groupId>
           <artifactId>jedis</artifactId>
           <version>2.9.0</version>
    </dependency>

2. JedisUtil.java

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.exceptions.JedisException;

public class JedisUtil {

   private static final Long UNLOCK_SUCCESS = 1L;
   private static JedisPool jedisPool = null;
   static {
       GenericObjectPoolConfig config = new GenericObjectPoolConfig();
       jedisPool = new JedisPool(config, "192.168.56.128", 6379, 6000, "666666");
   }

   public static Jedis getJedis() throws JedisException {
       Jedis jedis = null;
       try {
           jedis = jedisPool.getResource();
       } catch (JedisException e) {
           e.printStackTrace();
           throw e;
       }
       return jedis;
   }

}

3.RedisDataTest.java

package com.test.demo;

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

import redis.clients.jedis.Jedis;

public class RedisDataTest {

   public static void main(String[] args) {
       Jedis jedis = JedisUtil.getJedis();

       //字符类型
       jedis.set("username","dadd");
       jedis.set("username","wqqe");
System.out.println(jedis.get("username"));

//list
String listName = "list";
jedis.del(listName);
for (int i = 0; i < 10; i++) {
jedis.lpush(listName, "a"+String.valueOf(i));
}
System.out.println(jedis.lrange(listName,0,10));
System.out.println(jedis.lrange(listName,5,7));

//hash
String userKey = "userxxx";
jedis.hset(userKey,"name","jack");
jedis.hset(userKey,"age","26");
jedis.hset(userKey,"phone","1333165465");
System.out.println(jedis.hget(userKey,"name"));
System.out.println(jedis.hgetAll(userKey));

//set
String likekey1 = "setkey1";
String likekey2 = "setkey2";
for (int i = 0; i < 10; i++) {
jedis.sadd(likekey1,String.valueOf(i));
jedis.sadd(likekey2,String.valueOf(i*i));
}
System.out.println(jedis.smembers(likekey1));
System.out.println(jedis.smembers(likekey2));

//zset
String rankKey = "zsetKey";
jedis.zadd(rankKey,15,"ad");
jedis.zadd(rankKey,60,"www");
jedis.zadd(rankKey,90,"bbb");
jedis.zadd(rankKey,75,"ttt");
jedis.zadd(rankKey,80,"tom");
System.out.println(jedis.zcard(rankKey)); //计数
System.out.println(jedis.zcount(rankKey,61,100));
System.out.println(jedis.zscore(rankKey,"tom"));

//初始化表数据
List<Map<String,Object>> tableList = new ArrayList<Map<String,Object>>();
Map<String,Object> row1 = new HashMap<String,Object>();
row1.put("keyId", 1);
row1.put("userCode", "admin");
row1.put("userName", "管理员");
tableList.add(row1);

Map<String,Object> row2 = new HashMap<String,Object>();
row2.put("keyId", 2);
row2.put("userCode", "test");
row2.put("userName", "测试");
tableList.add(row2);

//存储表数据到redis
String tableName = "t_userinfo";
String tableNameKey = tableName+"keyId";
jedis.del(tableNameKey);
String keyId = "";
for (int i = 0; i < tableList.size(); i++) {
   Map<String,Object> row = tableList.get(i);
   keyId = String.valueOf(row.get("keyId"));
   //list存储主键
   jedis.lpush(tableNameKey, String.valueOf(keyId));
   //存储行数据
   jedis.del(tableName + keyId);
jedis.hset(tableName + keyId,"keyId",keyId);
jedis.hset(tableName + keyId,"userCode",(String) row.get("userCode"));
jedis.hset(tableName + keyId,"userName",(String) row.get("userName"));
}

       System.out.println(jedis.hgetAll(tableName+"1"));
       System.out.println(jedis.hgetAll(tableName+"2"));

//从redis中读取表数据
List<String> keyList = jedis.lrange(tableNameKey, 0, jedis.llen("tableNameKey")+1);
if(null != keyList && keyList.size() > 0){
   for (int i = 0; i < keyList.size(); i++) {
    String key = keyList.get(i);
    System.out.println(jedis.hgetAll(tableName+key));
   }
}
