redisclientsjedisexceptionsJedisConnectionException Could not get a resource from the pool

This exception is thrown when Jedis is unable to get a connection from the connection pool. This usually happens when there are no available connections in the pool, or when the connections in the pool are all being used.

To resolve this issue, you can try the following:

1. Increase the size of the connection pool. This can be done by setting the maxTotal parameter in your JedisPoolConfig object to a higher value.

2. Check if the Redis server is running and accessible. Make sure that the server is up and running, and that you are able to connect to it using the appropriate credentials.

3. Check if the Redis server has reached its maximum connection limit. If the server has reached its maximum connection limit, it may not be able to accept any more connections. You can check this by running the "redis-cli info" command and checking the "connected_clients" parameter.

4. Make sure that there are no network connectivity issues between your application and the Redis server. Check if there are any firewalls or other network devices that may be blocking the connection.

5. If none of the above solutions work, try restarting the Redis server and your application. This may help clear any temporary issues that may be causing the connection problem
