Redis

1，該文章主要介紹如何使用Jedis操作單節點redis資料,後續兩篇文章將介紹Jedis操作redis叢集及redisTemplate操作redis叢集；碼雲上面地址：https://gitee.com/dream21th/dream21th-redis

3，專案的application.properties配置

#redis
redis.host=192.168.1.81
redis.port=6379
redis.timeout=3
#redis.password=123456
redis.poolMaxTotal=10
redis.poolMaxIdle=10
redis.poolMaxWait=3

4，專案的config配置

@Service
public class RedisPoolFactory extends CachingConfigurerSupport{
@Autowired
RedisConfig redisConfig;
/**
* redis單例模式
* @return
*/
@Bean
public JedisPool JedisPoolFactory() {
JedisPoolConfig poolConfig = new JedisPoolConfig();
poolConfig.setMaxIdle(redisConfig.getPoolMaxIdle());
poolConfig.setMaxTotal(redisConfig.getPoolMaxTotal());
poolConfig.setMaxWaitMillis(redisConfig.getPoolMaxWait() * 1000);
JedisPool jp = new JedisPool(poolConfig, redisConfig.getHost(), redisConfig.getPort(),
redisConfig.getTimeout()*1000, redisConfig.getPassword(), 0);
return jp;

}

}
