无法获得Jedis连接;无法从池中获取资源 [英] Cannot get Jedis connection; Could not get a resource from the pool
问题描述
我每5分钟运行一次批处理作业,我不想让其他节点运行相同的工作,因此我使用Jedis锁来锁定对象5分钟。因此,如果其他节点尝试运行相同的作业,则不会获得锁定。获取锁定后工作开始,当我尝试从Redis读取时,我收到以下异常说
I am running a batch job for every 5 minutes and I don't wanna other nodes to run the same job hence I am using Jedis lock to lock an object for 5 minutes. So that other node won't get the lock if they try to run the same job. Job started after acquiring the lock and when I try to read it from Redis I am getting the following exception saying
'Caused by: redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool

这就是我的代码
@Bean
public Jedis getJedis()
{
Jedis jedis = new Jedis(this.redisHost, nteger.valueOf(this.redisPort));
jedis.auth(this.redisPassword);
return jedis;
}
spring-boot Application.properties文件
spring-boot Application.properties file
# DATA REDIS
spring.data.redis.repositories.enabled=true
# REDIS (RedisProperties)
spring.redis.host=10.160.49.22
spring.redis.password=qweqewqw
spring.redis.ssl=true
#spring.redis.pool.max-active=10
#spring.redis.pool.max-idle=10
# spring.redis.pool.max-wait=30000
spring.redis.port=6379
Job在开始时执行以下代码以获得锁定
Job executes the following code at the start to get the lock
JedisLock jedisLock = new JedisLock(jedis, getLockName(), getTimeInMillis());
jedisLoc.acquire()
之后redis存储库类试图读取a的值特殊模式..
After that redis repository class is trying to read values for a particular pattern..
List<String> hotelCodes = redisTemplate.execute(new RedisCallback<List<String>>() {
/**
* Gets called by {@link RedisTemplate} with an active Redis connection. Does not need to care about activating or
* closing the connection or handling exceptions.
*
* @param connection active Redis connection
* @return a result object or {@code null} if none
* @throws DataAccessException
*/
@Override
public List<String> doInRedis(RedisConnection connection) throws DataAccessException {
ScanOptions options = ScanOptions.scanOptions().match(pattern).count(1).build();
Cursor<Map.Entry<byte[], byte[]>> entries = connection.hScan(HASH_KEY.getBytes(), options);
List<String> result = new ArrayList<>();
if (entries != null)
while (entries.hasNext()) {
Map.Entry<byte[], byte[]> entry = entries.next();
byte[] actualValue = entry.getValue();
result.add(new String(actualValue));
}
return result;
}
});
return hotelCodes;
然后这是我在日志中看到的完整例外。
Then this is the complete exception I see in log.

任何人都知道为什么我会得到这个例外以及如何修复它?
Anyone knows why I get this exception and how to fix it?
推荐答案
从spring-managed redis连接池中获取Jedis实例:
Fetch Jedis instance from spring-managed redis connection pool:
Jedis jedis = (Jedis) redisTemplate.getConnectionFactory().getConnection().getNativeConnection();
然后你可以用它来实例化JedisLock。
Then u can use it to instantiate JedisLock.
