springboot of redis Distributed Lock

Tools are as follows:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisCallback;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.stereotype.Component;
import redis.clients.jedis.Protocol;
import redis.clients.util.SafeEncoder;

import java.io.Serializable;


@Component
public class RedisUtils {

    @Autowired
    private RedisTemplate redisTemplate;

    public RedisTemplate getRedisTemplate() {
        return this.redisTemplate;
    }

    /**
     * 设置redis分布式锁
     * @param key
     * @param value
     * @param expire 锁过期时间
     * @return
     */
    public boolean tryLock(final String key, final Serializable value, final long expire){
        boolean isSuccess = (boolean) redisTemplate.execute((RedisCallback) connection -> {
            RedisSerializer valueSerializer = redisTemplate.getValueSerializer();
            RedisSerializer keySerializer = redisTemplate.getKeySerializer();
            Object object = connection.execute("set",keySerializer.serialize(key),valueSerializer.serialize(value), SafeEncoder.encode("NX"),SafeEncoder.encode("EX"), Protocol.toByteArray(expire));
            return null != object;
        });
        return isSuccess;
    }
　　//释放锁
    public boolean releaseLock(String key){
        return  redisTemplate.delete(key);
    }
