写一个java版本的redis各种数据类型的工具类

好的，以下是一个基于Java的Redis各种数据类型的工具类示例：

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;

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

public class RedisUtil {

    private static JedisPool jedisPool = null;

    static {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxTotal(100);
        jedisPoolConfig.setMaxIdle(20);
        jedisPoolConfig.setTestOnBorrow(true);
        jedisPool = new JedisPool(jedisPoolConfig, "localhost", 6379);
    }

    public static Jedis getJedis() {
        return jedisPool.getResource();
    }

    public static void returnJedis(Jedis jedis) {
        jedisPool.returnResource(jedis);
    }

    /**
     * String类型
     */
    public static void set(String key, String value) {
        Jedis jedis = null;
        try {
            jedis = getJedis();
            jedis.set(key, value);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            returnJedis(jedis);
        }
    }

    public static String get(String key) {
        Jedis jedis = null;
        try {
            jedis = getJedis();
            return jedis.get(key);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        } finally {
            returnJedis(jedis);
        }
    }

    /**

            jedis.lpush(key, values);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            returnJedis(jedis);
        }
    }

    public static List<String> lrange(String key, long start, long end) {
        Jedis jedis = null;
        try {
            jedis = getJedis();
            return jedis.lrange(key, start, end);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        } finally {
            returnJedis(jedis);
        }
    }

    /**
     * Set类型
     */
    public static void sadd(String key, String... members) {
        Jedis jedis = null;
        try {
            jedis = getJedis();
            jedis.sadd(key, members);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            returnJedis(jedis);
        }
    }

    public static Set<String> smembers(String key) {
        Jedis jedis = null;
        try {
            jedis = getJedis();
            return jedis.smembers(key);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        } finally {
            returnJedis(jedis);
        }
    }

    /**
     * Hash类型
     */
    public static void hset(String key, String field, String value) {
        Jedis jedis = null;
        try {
            jedis = getJedis();
            jedis.hset(key, field, value);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            returnJedis(jedis);
        }
    }

    public static String hget(String key, String field) {
        Jedis jedis = null;
        try {
            jedis = getJedis();
            return jedis.hget(key, field);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        } finally {
            returnJedis(jedis);
        }
    }

    public static Map<String, String> hgetAll(String key) {
        Jedis jedis = null;
        try {
            jedis = getJedis();
            return jedis.hgetAll(key);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        } finally {
            returnJedis(jedis);
        }
    }

    /**
     * Zset类型
     */
    public static void zadd(String key, double score, String member) {
        Jedis jedis = null;
        try {
            jedis = getJedis();
            jedis.zadd(key, score, member);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            returnJedis(jedis);
        }
    }

    public static Set<String> zrange(String key, long start, long end) {
        Jedis jedis = null;
        try {
            jedis = getJedis();
            return jedis.zrange(key, start, end);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        } finally {
            returnJedis(jedis);
        }
    }

}

这个工具类中包含了如何初始化Jedis连接池、获取、释放Jedis连接以及常用的String、List、Set、Hash、Zset数据类型的操作。您可以在使用该工具类时，根据需要进行调整和扩展。
