1.依賴 （注意版本問題）

<dependency>
			<groupId>redis.clients</groupId>
			<artifactId>jedis</artifactId>
			<version>2.5.0</version>
</dependency>
<dependency>
			<groupId>org.springframework.data</groupId>
			<artifactId>spring-data-redis</artifactId>
			<version>1.7.2.RELEASE</version>
</dependency>
 

2.連線配置

server.port=9123
spring.redis.database=0
spring.redis.host=127.0.0.1
spring.redis.port=6379
spring.redis.pool.max-active=8
spring.redis.pool.max-wait=-1
spring.redis.pool.max-idle=8
spring.redis.pool.min-idle=0
spring.redis.timeout=0

3.RedisConfig配置

@Configuration
public class RedisConfig {
    @Bean
    @SuppressWarnings("all")
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
        template.setConnectionFactory(factory);
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        // key採用String的序列化方式
        template.setKeySerializer(stringRedisSerializer);
        // hash的key也採用String的序列化方式
        template.setHashKeySerializer(stringRedisSerializer);
        // value序列化方式採用jackson
        template.setValueSerializer(jackson2JsonRedisSerializer);
        // hash的value序列化方式採用jackson
        template.setHashValueSerializer(jackson2JsonRedisSerializer);
        template.afterPropertiesSet();
        return template;
    }
}
 

4.Redi工具類

@Component
public final class RedisUtil {

@Autowired
private RedisTemplate<String, Object> redisTemplate;

    /* =============================common============================ */
    /**
     * 指定快取失效時間
     * @param key 鍵

     */

    try {
        if (time > 0) {
            redisTemplate.expire(key, time, TimeUnit.SECONDS);
        }
        return true;
    } catch (Exception e) {
        e.printStackTrace();
        return false;
    }
}
    /**
     * 根據key 獲取過期時間
     * @param key 鍵 不能為null
     * @return 時間(秒) 返回0代表為永久有效
     */

public long getExpire(String key) {
    return redisTemplate.getExpire(key, TimeUnit.SECONDS);
}
    /**
     * 判斷key是否存在
     * @param key 鍵
     * @return true 存在 false不存在
     */

public boolean hasKey(String key) {
    try {
        return redisTemplate.hasKey(key);
    } catch (Exception e) {
        e.printStackTrace();
        return false;
    }
}

    /**
     * 刪除快取
     * @param key 可以傳一個值 或多個
     */
@SuppressWarnings("unchecked")

public void del(String... key) {
    if (key != null && key.length > 0) {
        if (key.length == 1) {
            redisTemplate.delete(key[0]);
        } else {
            redisTemplate.delete(CollectionUtils.arrayToList(key));
        }
    }
}
    // ============================String=============================
    /**
     * 普通快取獲取
     * @param key 鍵
     * @return 值
     */
public Object get(String key) {
    return key == null ? null : redisTemplate.opsForValue().get(key);
}
    /**
     * 普通快取放入
     * @param key 鍵
     * @param value 值
     * @return true成功 false失敗
     */

public boolean set(String key, Object value) {
    try {
        redisTemplate.opsForValue().set(key, value);
        return true;
    } catch (Exception e) {
        e.printStackTrace();
        return false;
    }
}
    /**
     * 普通快取放入並設定時間
     * @param key 鍵
     * @param value 值
     * @param time 時間(秒) time要大於0 如果time小於等於0 將設定無限期
     * @return true成功 false 失敗
     */

public boolean set(String key, Object value, long time) {
    try {
        if (time > 0) {
            redisTemplate.opsForValue().set(key, value, time, TimeUnit.SECONDS);
        } else {
