使用JedisPoolConfig了吗?是不是连接池没有可用链接了?
JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
// 设置最大连接数
jedisPoolConfig .setMaxTotal(3000); // 可以创建3000jedis实例
// 设置最大空闲连接数
jedisPoolConfig .setMaxIdle(300);
//等待可用连接的最大时间
jedisPoolConfig .setMaxWaitMillis(10000);
//在borrow一个jedis实例时,是否提前进行validate操作;如果为true,则得到的jedis实例均是可用的
jedisPoolConfig .setTestOnBorrow(true);
//创建JedisPool
JedisPool jedisPool = new JedisPool(jedisPoolConfig , "url", port);
//获取Jedis
Jedis jedis = jedisPool.getResource();
//jedis操作
//关闭连接
jedis.close();
jedisPool .close();
希望有用
