根據配置RedisProperties自動獲取RedisConnectionFactory

#單點配置
spring.redis.host=192.168.1.1
spring.redis.port=6379

#哨兵配置
#spring.redis.sentinel.master=common
#spring.redis.sentinel.nodes=192.168.1.84:26379,192.168.1.85:26379
#spring.redis.password=123456

#集羣配置
#spring.redis.cluster.nodes=192.168.1.24:6389,192.168.1.24:6479,192.168.1.24:6579
#spring.redis.password=123456

1.增加依賴

     <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
            <version>1.5.2.RELEASE</version>
        </dependency>

 

 

  1. org.springframework.boot.autoconfigure.data.redis.RedisProperties 會根據配置自動加載爲一個bean

@ConfigurationProperties(prefix = "spring.redis")

3.使用方式

   @Autowired
    private RedisTemplate<String,Object> redisTemplate;
    // 操作String類型
    redisTemplate.opsForValue().set("key","v1");

 

4.其他類型的獲取

// hash結構
redisTemplate.opsForHash();

//set 結構
redisTemplate.opsForSet();

// sortedset
redisTemplate.opsForZSet();

//list
redisTemplate.opsForList();

 

5. key類的操作

public boolean existsKey(String key) {
        return redisTemplate.hasKey(key);
}

/**
     * 刪除key
     *
     * @param key
*/
 public void deleteKey(String key) {
        redisTemplate.delete(key);
}

/**
     * 設置key的生命週期
     *
     * @param key
     * @param time
     * @param timeUnit
*/
public void expireKey(String key, long time, TimeUnit timeUnit) 
        redisTemplate.expire(key, time, timeUnit);
}
