redis提示Could not get a resource from the pool

[qq_25545983]

jredis连接池不能找到，但是最初启动的时候是开始的，运行一段时间之后就会报下面错误，求解？
报错：

连接池构建如下
public final class RedisConfig {
//Redis服务器IP
private static String ADDR = "121.199.**.**";
//Redis的端口号
private static int PORT = 6379;
//访问密码
private static String AUTH = "jiuzhekan_redis_password";
//可用连接实例的最大数目，默认值为8；
//如果赋值为-1，则表示不限制；如果pool已经分配了maxActive个jedis实例，则此时pool的状态为exhausted(耗尽)。
private static int MAX_ACTIVE = 1024;
//控制一个pool最多有多少个状态为idle(空闲的)的jedis实例，默认值也是8。
private static int MAX_IDLE = 200;
//等待可用连接的最大时间，单位毫秒，默认值为-1，表示永不超时。如果超过等待时间，则直接抛出JedisConnectionException；
private static int MAX_WAIT = 10000;
private static int TIMEOUT = 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；
private static boolean TEST_ON_BORROW = true;
private static JedisPool jedisPool = null;
/**
* 初始化Redis连接池
*/
static {
try {
JedisPoolConfig config = new JedisPoolConfig();
config.setMaxActive(MAX_ACTIVE);
config.setMaxIdle(MAX_IDLE);
config.setMaxWait(MAX_WAIT);
config.setTestOnBorrow(TEST_ON_BORROW);
jedisPool = new JedisPool(config, ADDR, PORT, TIMEOUT);
} catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
}
}

/**
* 获取Jedis实例
* @return
*/
public synchronized static Jedis getJedis() {
try {
if (jedisPool != null) {
Jedis resource = jedisPool.getResource();
return resource;
} else {
return null;
}
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
/**
* 释放jedis资源
* @param jedis
*/
public static void returnResource(Jedis jedis) {
if (jedis != null) {
jedisPool.returnResourceObject(jedis);
}
}
}

每次调用的时候最终都会释放资源：
public static <T> List<T> getList(String key){
Jedis jedis=getJedis();
List<T> list=null;
try{
if(jedis== null || !jedis.exists(key.getBytes())){
return null;
}
byte[] in =jedis.get(key.getBytes());
list= (List<T>) ObjectTranscoder.deserialize(in);
}catch(Exception e){
System.out.println(e.getMessage());
}finally{
RedisConfig.returnResource(jedis);
}
return list;
}


求解？
