redis-cluster通用java接口

1.redis-cluster

通过结合jedis和spring-data-redis包开发的一个简易方便的redis 集群访问接口。对于redis-cluster方式集群安装参照：http://blog.csdn.net/cweeyii/article/details/71298905

2 redis-cluster接口

整个工程代码：https://github.com/cweeyii/redis-parent
接口类：

public interface IRedis {
    void setHashObject(K key, Map fieldValues, int expireSecond);

    void setHashObject(K key, Map fieldValues);

    Map getHashObject(K key, List fields);

    boolean expire(K key, int expireSeconds);

    void setObject(K key, HV value, int expireSecond);

    void setObject(K key, HV value);

    HV getObject(K key);
}

实现类：

@Component
public class RedisImpl implements IRedis {
    private static final int DEFAULT_EXPIRED_TIME=7*24*3600;
    @Resource
    private RedisTemplate redisTemplate;

    public void setHashObject(K key, Map fieldValues, int expireSecond) {
        HashOperations valueOperate = redisTemplate.opsForHash();
        if (!CollectionUtils.isEmpty(fieldValues)) {
            valueOperate.putAll(key, fieldValues);
        }
        expire(key, expireSecond);
    }

    @Override
    public void setHashObject(K key, Map fieldValues) {
        setHashObject(key,fieldValues, DEFAULT_EXPIRED_TIME);
    }

    public Map getHashObject(K key, List fields) {
        HashOperations valueOperate = redisTemplate.opsForHash();

        Map map = new HashMap<>();
        if (!CollectionUtils.isEmpty(fields)) {
            for (HK field : fields) {
                HV obj = valueOperate.get(key, field);
                map.put(field, obj);
            }
        }
        return map;
    }

    public boolean expire(K key, int expireSeconds) {
        return redisTemplate.expire(key, expireSeconds, TimeUnit.SECONDS);
    }

    public void setObject(K key, HV value, int expireSecond) {
        ValueOperations valueOperate = redisTemplate.opsForValue();
        valueOperate.set(key, value);
        redisTemplate.expire(key, expireSecond, TimeUnit.SECONDS);
    }

    @Override
    public void setObject(K key, HV value) {
        setObject(key,value,DEFAULT_EXPIRED_TIME);
    }

    public HV getObject(K key) {
        ValueOperations valueOperate = redisTemplate.opsForValue();
        return valueOperate.get(key);
    }
}
