**简介**

Jedis Client是Redis官网推荐的一个面向java客户端，库文件实现了对各类API进行封装调用。  
Jedis源码工程地址：

[https://github.com/xetorthio/jedis][https_github.com_xetorthio_jedis]

**使用**

想要使用Jedis必须加载jar包或者添加maven依赖，jar包可以自己上网下载，我的是Maven项目，所以在pom.xml中增加如下语句：

<dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>2.9.0</version>
        <type>jar</type>
        <scope>compile</scope>
    </dependency>

**简单的Jedis实例**

在加载Jedis JAR包之后，我们可以直接使用新建一个Jedis实例的方法，来建立一个到Redis的连接，并进行操作，以下是一个简单的jedis实例：

public void setup() {
     //连接redis服务器
            jedis = new Jedis("172.24.4.183", 6379);
    //        jedis.auth("redis");//验证密码,如果需要验证的话
        }
    /**
     * 键操作
     */
    public void testKey()  throws InterruptedException{
        System.out.println("清空数据："+jedis.flushDB());
        System.out.println("判断某个键是否存在："+jedis.exists("username"));
        System.out.println("新增<'username','xmr'>的键值对："+jedis.set("username", "xmr"));
        System.out.println(jedis.exists("username"));
        System.out.println("新增<'password','password'>的键值对："+jedis.set("password", "123"));
        System.out.print("系统中所有的键如下：");
        Set<String> keys = jedis.keys("*");
        System.out.println(keys);
        System.out.println("删除键password:"+jedis.del("password"));
        System.out.println("判断键password是否存在："+jedis.exists("password"));
        System.out.println("设置键username的过期时间为5s:"+jedis.expire("username", 8));
        TimeUnit.SECONDS.sleep(2);
        System.out.println("查看键username的剩余生存时间："+jedis.ttl("username"));
        System.out.println("移除键username的生存时间："+jedis.persist("username"));
        System.out.println("查看键username的剩余生存时间："+jedis.ttl("username"));
        System.out.println("查看键username所存储的值的类型："+jedis.type("username"));
    }

输出结果：

**字符串操作**

输出结果：

public void testString() throws InterruptedException {
        jedis.flushDB();
        System.out.println("===========增加数据===========");
        System.out.println(jedis.set("key1", "value1"));
        System.out.println(jedis.set("key2", "value2"));
        System.out.println(jedis.set("key3", "value3"));
        System.out.println("删除键key2:" + jedis.del("key2"));
        System.out.println("获取键key2:" + jedis.get("key2"));
        System.out.println("修改key1:" + jedis.set("key1", "1"));
        System.out.println("获取key1的值：" + jedis.get("key1"));
        System.out.println("在key3后面加入值：" + jedis.append("key3", "End"));
        System.out.println("key3的值：" + jedis.get("key3"));
        System.out.println("增加多个键值对：" + jedis.mset("key01", "value01", "key02", "value02", "key03", "value03"));
        System.out.println("获取多个键值对：" + jedis.mget("key01", "key02", "key03"));
        System.out.println("获取多个键值对：" + jedis.mget("key01", "key02", "key03", "key04"));
        System.out.println("删除多个键值对：" + jedis.del(new String[]{"key01", "key02"}));
        System.out.println("获取多个键值对：" + jedis.mget("key01", "key02", "key03"));
    
        jedis.flushDB();
        System.out.println("===========新增键值对,防止覆盖原先值==============");
        System.out.println(jedis.setnx("key1", "value1"));
        System.out.println(jedis.setnx("key2", "value2"));
        System.out.println(jedis.setnx("key2", "value2-new"));
        System.out.println(jedis.get("key1"));
        System.out.println(jedis.get("key2"));
    
        System.out.println("===========新增键值对并设置有效时间=============");
        System.out.println(jedis.setex("key3", 2, "value3"));
        System.out.println(jedis.get("key3"));
        TimeUnit.SECONDS.sleep(3);
        System.out.println(jedis.get("key3"));
    
        System.out.println("===========获取原值，更新为新值==========");//GETSET is an atomic set this value and return the old value command.
        System.out.println(jedis.getSet("key2", "key2GetSet"));
        System.out.println(jedis.get("key2"));
    
        System.out.println("获得key2的值的字串：" + jedis.getrange("key2", 2, 4));
    }

        map.put("key1", "value1");
        map.put("key2", "value2");
        map.put("key3", "value3");
        map.put("key4", "value4");
        jedis.hmset("hash", map);
        jedis.hset("hash", "key5", "value5");
        System.out.println("散列hash的所有键值对为：" + jedis.hgetAll("hash"));//return Map<String,String>
        System.out.println("散列hash的所有键为：" + jedis.hkeys("hash"));//return Set<String>
        System.out.println("散列hash的所有值为：" + jedis.hvals("hash"));//return List<String>
        System.out.println("将key6保存的值加上一个整数，如果key6不存在则添加key6：" + jedis.hincrBy("hash", "key6", 6));
        System.out.println("散列hash的所有键值对为：" + jedis.hgetAll("hash"));
        System.out.println("将key6保存的值加上一个整数，如果key6不存在则添加key6：" + jedis.hincrBy("hash", "key6", 3));

        System.out.println("lists区间0-3的元素：" + jedis.lrange("lists", 0, 3));
        System.out.println("===============================");
        // 删除列表指定的值 ，第二个参数为删除的个数（有重复时），后add进去的值先被删，类似于出栈
        System.out.println("删除指定元素个数：" + jedis.lrem("lists", 2, "HashMap"));
        System.out.println("lists的内容：" + jedis.lrange("lists", 0, -1));

        System.out.println(jedis.sadd("eleSet", "e6"));
        System.out.println("eleSet的所有元素为：" + jedis.smembers("eleSet"));
        System.out.println("删除一个元素e0：" + jedis.srem("eleSet", "e0"));
        System.out.println("eleSet的所有元素为：" + jedis.smembers("eleSet"));
        System.out.println("删除两个元素e7和e6：" + jedis.srem("eleSet", "e7", "e6"));
        System.out.println("eleSet的所有元素为：" + jedis.smembers("eleSet"));
        System.out.println("随机的移除集合中的一个元素：" + jedis.spop("eleSet"));
        System.out.println("eleSet的所有元素为：" + jedis.smembers("eleSet"));
        System.out.println("eleSet中包含元素的个数：" + jedis.scard("eleSet"));

        System.out.println("=================================");
        System.out.println(jedis.sadd("eleSet1", "e1", "e2", "e4", "e3", "e0", "e8", "e7", "e5"));
        System.out.println(jedis.sadd("eleSet2", "e1", "e2", "e4", "e3", "e0", "e8"));
        System.out.println("将eleSet1中删除e1并存入eleSet3中：" + jedis.smove("eleSet1", "eleSet3", "e1"));
        System.out.println("eleSet1中的元素：" + jedis.smembers("eleSet1"));

**JedisPool应用**

虽然我们可以简单地创建Jedis使用，但每次操作的时候，都建立连接，很耗费性能。解决方法就是从一个连接池中取出连接对象，用完还回去。使用连接池的方案还能解决很多同步性问题。在Jedis中，管理Redis连接的类是JedisPool。要想使用JedisPool需要添加jar包或依赖库，在pom.xml中添加

<dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-pool2</artifactId>
        <version>2.4.2</version>
    </dependency>

*  普通连接池连接

实现方式有两种，一种是通过配置文件(properties文件)，我的文件名是jedisPool.properties：

#最大分配的对象数
    
    redis.pool.maxTotal=1024
    
    #最大能够保持idel状态的对象数
    
    redis.pool.maxIdle=200
    
    #当池内没有返回对象时，最大等待时间
    
    redis.pool.maxWait=1000
    
    #当调用borrow Object方法时，是否进行有效性检查
    
    redis.pool.testOnBorrow=true
    
    #当调用return Object方法时，是否进行有效性检查
    
    redis.pool.testOnReturn=true
    
    #IP
    
    redis.ip=172.24.4.183
    
    #Port
    
    redis.port=6379

**java类如下：**

public class JedisUtil {
        private static Jedis jedis;
        private static JedisPool jedisPool = null;
        /**
         * 初始化Redis连接池
         */
        static {
            ResourceBundle bundle = ResourceBundle.getBundle("jedisPool");
            if (bundle == null) {
                throw new IllegalArgumentException(
                        "[jedisPool.properties] is not found!");
            }
            JedisPoolConfig config = new JedisPoolConfig();
            config.setMaxTotal(Integer.valueOf(bundle
                    .getString("redis.pool.maxTotal")));
            config.setMaxIdle(Integer.valueOf(bundle
                    .getString("redis.pool.maxIdle")));
            config.setMaxWaitMillis(Long.valueOf(bundle.getString("redis.pool.maxWait")));
            config.setTestOnBorrow(Boolean.valueOf(bundle
                    .getString("redis.pool.testOnBorrow")));
            config.setTestOnReturn(Boolean.valueOf(bundle
                    .getString("redis.pool.testOnReturn")));
            jedisPool = new JedisPool(config, bundle.getString("redis.ip"),
                    Integer.valueOf(bundle.getString("redis.port")));
            // 从池中获取一个Jedis对象
             jedis = jedisPool .getResource();
        }
        public void add(String sn) {
            jedis.sadd("snSet", sn);
            jedisPool.destroy();
        }
        public void remove(String sn) {
            jedis.srem("snSet", sn);
        }
        public boolean isExist(String sn) {
            Set<String> snSet = jedis.smembers("snSet");
            return snSet.contains(sn);
        }
        public static void main(String[] args) {
            String keys = "name";
    // 删数据
            jedis.del(keys);
    // 存数据
            jedis.set(keys, "snowolf");
    // 取数据
            String value = jedis.get(keys);
            System.out.println(value);
    // 释放对象池
    //        jedisPool.returnResource(jedis);
        }
    }

而直接通过代码实现的话，其实也是一个原理：

public class JedisUtil1 {
    private static JedisUtil1 instance = null;
    private Jedis jedis;
    private static JedisPool jedisPool = null;

*  Sentinel连接池连接

Sentinel连接池用于应对Redis的Sentinel的主从切换机制，能够正确在服务器宕机导致服务器切换时得到正确的服务器连接，当服务器采用该部署策略的时候推荐使用该连接池进行操作

private static Jedis jedis;
    private static JedisSentinelPool jedisSentinelPool = null;
    
    /**
     * 初始化Redis连接池
     */
    static {
        ResourceBundle bundle = ResourceBundle.getBundle("jedisSentinePool");
        if (bundle == null) {
            throw new IllegalArgumentException(
                    "[jedisSentinePool.properties] is not found!");
        }
        JedisPoolConfig config = new JedisPoolConfig();
        config.setMaxTotal(Integer.valueOf(bundle
                .getString("redis.pool.maxTotal")));
        config.setMaxIdle(Integer.valueOf(bundle
                .getString("redis.pool.maxIdle")));
        config.setMaxWaitMillis(Long.valueOf(bundle.getString("redis.pool.maxWait")));
        config.setTestOnBorrow(Boolean.valueOf(bundle
                .getString("redis.pool.testOnBorrow")));
        config.setTestOnReturn(Boolean.valueOf(bundle
                .getString("redis.pool.testOnReturn")));
        //监听器列表
        Set<String> sentinels = new HashSet<>();
        /**
         *
         //监听器1
         sentinels.add(new HostAndPort("172.24.4.183", 26379).toString());
         //监听器2
         sentinels.add(new HostAndPort("172.24.4.184", 26379).toString());
         //实际使用的时候在properties里配置即可：redis.sentinel.hostandports=172.24.4.183:26379, 172.24.4.184:26379
         //然后使用 bundle.getString("redis.sentinel.hostandports");获取地址
         */
        //mastername是服务器上的master的名字，在master服务器的sentinel.conf中配置
        String masterName = bundle.getString("redis.sentinel.masterName");
        sentinels.add(bundle.getString("redis.sentinel.hostandports"));
        //初始化连接池
        jedisSentinelPool = new JedisSentinelPool(masterName,
                sentinels, config);
        // 从池中获取一个Jedis对象
        jedis = jedisSentinelPool.getResource();
    }

*  ShardedJedisPool连接池分片连接

Memcached完全基于分布式集群，而Redis是Master-Slave，Redis在容灾处理方面可以通过服务器端配置Master-Slave模式来实现。如果想把Reids做成集群模式，无外乎多做几套Master-Slave，每套Master-Slave完成各自的容灾处理，通过Client工具来实现一致性哈希分布存储，即key分片存储。

shared一致性哈希采用以下方案：

1.  Redis服务器节点划分：将每台服务器节点采用hash算法划分为160个虚拟节点(可以配置划分权重)
2.  将划分虚拟节点采用TreeMap存储
3.  对每个Redis服务器的物理连接采用LinkedHashMap存储
4.  对Key or KeyTag 采用同样的hash算法，然后从TreeMap获取大于等于键hash值得节点，取最邻近节点存储；当key的hash值大于虚拟节点hash值得最大值时，存入第一个虚拟节点

sharded采用的hash算法：MD5 和 MurmurHash两种；默认采用64位的MurmurHash算法；有兴趣的可以研究下~

保留前面的JedisPoolConfig，新增两个Redis的IP（redis1.ip，redis2.ip），完成两个JedisShardInfo实例，并将其丢进List中：

private static ShardedJedis jedis;
    private static ShardedJedisPool shardedJedisPool = null;
    /**
     * 初始化Redis连接池
     */
    static {
        ResourceBundle bundle = ResourceBundle.getBundle("sharedJedisPool");
        if (bundle == null) {
            throw new IllegalArgumentException(
                    "[jedisPool.properties] is not found!");
        }
        JedisPoolConfig config = new JedisPoolConfig();
        config.setMaxTotal(Integer.valueOf(bundle
                .getString("redis.pool.maxTotal")));
        config.setMaxIdle(Integer.valueOf(bundle
                .getString("redis.pool.maxIdle")));
        config.setMaxWaitMillis(Long.valueOf(bundle.getString("redis.pool.maxWait")));
        config.setTestOnBorrow(Boolean.valueOf(bundle
                .getString("redis.pool.testOnBorrow")));
        config.setTestOnReturn(Boolean.valueOf(bundle
                .getString("redis.pool.testOnReturn")));
        JedisShardInfo jedisShardInfo1 = new JedisShardInfo(
                bundle.getString("redis1.ip"), Integer.valueOf(bundle.getString("redis.port")));
        JedisShardInfo jedisShardInfo2 = new JedisShardInfo(
                bundle.getString("redis2.ip"), Integer.valueOf(bundle.getString("redis.port")));
        List<JedisShardInfo> list = new LinkedList<>();
        list.add(jedisShardInfo1);
        list.add(jedisShardInfo2);
        shardedJedisPool = new ShardedJedisPool(config,list);
        // 从池中获取一个Jedis对象
        jedis = shardedJedisPool.getResource();
    }
